Criteria for good car speakers in the vehicle

Published

on

What are the criteria for good car speakers in vehicles and which factors do you have to take into
account? You can find the answer in this post. Car speakers are the core of the music system in the
vehicle, if the quality is poor or if they become damaged over time and start to scratch, the time has
come to make a change. People are spending more and more time in vehicles because the traffic is
very slow, depending on the location. A good performance of the music system is very important
because it influences our concentration and mood.

But what are the criteria for good car speakers that have to match the respective vehicle model. The
first and most important value is the size that the original speakers should correspond to, otherwise
they will not fit into the original installation locations in the vehicle. There is the possibility to get
advice from specialists who concentrate on these areas for vehicle-specific loudspeaker installation
sets. The company Auto-Lautsprecher.eu is such a provider with loudspeaker installation sets for car
brands in which these loudspeakers fit into the original installation locations of the respective model.

In addition to the correct size of the car speakers, the mounting rings and adapter cables also have to
fit perfectly so that the installation later works without any problems. All of these factors play a
major role in the decision on a suitable loudspeaker installation set. Installation tutorials in which the
exact installation in the respective vehicle is explained are of great help in making the decision. The
dismantling of the door panels and the original loudspeakers is described step by step, with plenty of
pictures and information on the tools required.

Where can you find such installation tips?

Such installation tips must be written by professionals who know exactly how new speakers can be
successfully installed in the car. The company Auto-Lautsprecher.eu has experts with years of
experience who know exactly how they have to be installed in the various vehicle models, under the
following link Auto-Lautsprecher Einbau-Tipps you will find what you are looking for in numerous
instructions. Suitable offers for loudspeaker installation sets are also offered on the platform.


Another important value for car speakers is the quality of the manufacturer. There are vehicles with
premium music systems, but standard loudspeakers in the vehicle are always manufactured very
cheaply because the car brands do not attach great importance to special quality. Here you can
achieve a great improvement of the entire music system with the installation of branded goods.

Branded goods from top loudspeaker manufacturers have different components in the case of
crossovers, the membranes of the loudspeakers and the entire tuning of a loudspeaker system.
Standard car speakers are only made of paper cones and small magnets, so they have a very low load
capacity and tend to distort immediately at higher volumes. The value of the components of a 2-way
loudspeaker system is precisely determined by these factors, not only the pure wattage is important
here. If you consider these factors, a bad buy is impossible.

How to Prevent a Power Surge Damage

Published

on

By

A power surge occurs due to a quick rise in the voltage, higher than the actual level that travels through any outlet of your home. It is important to protect devices like appliances, computers and other electrically- powered elements during a power surge as it can cause a havoc.

  • What causes a power surge?

A power surge takes place by an interruption in the flow of electricity leading to a short or an increased delivery of power while the electricity is sent back into the system.

Given below are some of the main reasons leading to a power surge:

  1. Electrical overload: Overusing of an extension cord or plugging in too many devices into the same circuit can lead to electrical overloads following which a power surge could occur due to a massive current or a voltage spike from excess utilization of power from a single unit.
  2. Faulty wiring: A damaged or an exposed electrical wire causes faults leading to a power surge which are unlikely to be discovered if they are located behind the walls. Signs like burn marks, burning smell from an outlet or a buzzing sound indicates a faulty wiring. It is suggested to unplug the devices or turn of the electricity immediately after a power surge and appoint a local electrician in Pakenham that will ensure your safety by checking all the wires correctly.
  3. Lighting: Lighting doesn’t directly damage the appliances but can trigger a power surge by creating an extreme load on your home’s electrical system leading to a tremendous rise in voltage. It is advisable to unplug all such devices during severe storms incase they miss out surge protection.
  4. Power grid failure: Fixtures in a failed power grid leads to a rise in electrical current after restoration thus, creating a power surge.
  • Signs of a power surge: It is important to detect a power surge to ensure your house’s safety.
  • Flickering lights and sudden brightness in your TV and computers indicates a power surge.
  • Power surges often causes a device to go into a reset mode.
  • A detectable burnt smell after burst of power from electrical circuits.
  • Tripping of circuit breakers leading to a fire.
  • Tips to prevent a power surge:
  1. Unplug everything during a storm: You must unplug devices like computers, smaller electronic appliances like gaming system to protect them from a havoc.
  2. Use appliance-grade surge protectors for sensitive electronics: Surge protectors works the best during a power surge. You must purchase appliance grade surge protectors for refrigerator, washer, dryer, air conditioning and other appliances.
  3. Install a whole home surge protector: A home surge protector acts as a barrier of protection between home’s electrical system and the power grid. It is installed on the electrical box to prevent from power surges. Have an electrician to evaluates and audits your wiring to identify any potential threats as an old and outdated wiring can lead to surges. 
  4. Invest in energy efficient appliances: Air conditioning units and refrigerators are more efficient and are designed to lower the electricity bills. They draw less electricity and are resistant in comparison to old appliances.
  5. Beware of the post outage: A power surge always accompanies a power outage so, it is beneficial to power off all the electronics including an Air Conditioner after you experience an outage.
  6. Distribute your appliances: You must distribute your appliances and surge protectors between outlets, extension cords and power strips. Rather than combining the television and computer it is better to distribute them so as to prevent any overloading of an outlet.
  • Steps to take after a power surge:
  1. Before resetting your circuit breakers after a power surge, reset and unplug all the electronics.
  2. Asses any damages in your home by inspecting all the outlets and devices.
  3. Check your HVAC if it needs any professional help.

What is a Proximity Sensor?

What is a Proximity Sensor

Proximity sensor is a general term for sensors that replace the contact detection methods such as limit switches and aim to detect without touching the detection object. It can detect the movement information and presence information of objects and convert them  into electrical signals. Among the detection methods of  electrical signals, there are methods that utilize eddy currents generated in a metal object to be detected by electromagnetic induction, methods that capture changes in the capacity of electrical signals due to the proximity of the object to be detected, and methods that use sharp stones and guide switches. Proximity sensor is a device with the ability to sense the proximity of objects. It uses the sensitive characteristics of displacement sensors to approaching objects to identify the proximity of objects and output corresponding switch signals. Therefore, proximity sensors are usually called proximity switches. 

In the JIS standard, the JIS standard (JIS C 8201-5-2 Low-voltage switchgear and control device, fifth control circuit device and switching element, second section proximity switch) was established based on IEC60947-5-2 non-contact position detection switch. In the definition of JIS, products that can also detect the proximity of an object in a non-contact manner and the presence or absence of a nearby detection object are collectively referred to as “proximity switches”. It is composed of induction type, electrostatic capacitance type, ultrasonic type, photoelectric type, magnetic type and so on. In this technical guide, inductive proximity sensors that detect the presence of metals, capacitive proximity sensors that detect the presence of metallic and non-metallic objects, and switches that utilize a DC magnetic field generated by magnetic force are defined as “proximity sensors”.

Proximity Sensor Types and Working Principle

Capacitive Proximity Sensor

Capacitive proximity sensor is an electric capacitance proximity switch with electrodes as detection terminals. It consists of high frequency oscillation circuit, detection circuit, amplifier circuit, shaping circuit, and output circuit.

Usually there is a certain capacitance between the detection electrode and the ground, which becomes an integral part of the oscillation circuit. When the detected object is close to the detection electrode, due to the voltage applied to the detection electrode is C=Q/V, the detection electrode will be subjected to electrostatic induction to generate polarization. The closer the detected object is to the detection electrode, the more induced charges on the detection electrode. Since the electrostatic capacitance exits on the detection electrode, the capacitance C of the detection electrode increases as the amount of charge increases. Since the oscillation frequency of the oscillation circuit  is inversely proportional to the capacitance, when the capacitance C increases, the oscillation of the oscillation circuit weakens, or even stops the oscillation. The two states of oscillation and stop of the oscillation circuit are converted into switching signals by the detection circuit and then output to the outside.

Inductive Proximity Sensor

Inductive proximity sensor consists of a high-frequency oscillation circuit, a detection circuit, an amplifying circuit, a shaping circuit and an output circuit. The detection sensitive element is the detection coil, which is an integral part of the oscillating circuit, and the oscillating frequency of the oscillating circuit is . When the detection coil is connected to alternating current, an alternating magnetic field is generated around the detection coil. When the metal object approaches the detection coil, the metal object will generate eddy current and absorb the magnetic field energy, so that the inductance L of the detection coil changes. Thereby, the oscillation frequency of the oscillation circuit is reduced, and the oscillation is stopped. The two states of oscillation and vibration stop are converted into switching signal output by the monitoring circuit.

It should be noted that: the same as the capacitive proximity sensor, the measured object detected by the inductive proximity sensor is also a metal conductor, and non-metallic conductors cannot be measured by this method. Amplitude changes vary depending on the type of target metal, so the detection distance also varies depending on the type of target metal.

Photoelectric Proximity Sensor

In the photoelectric proximity sensor, the beam axis of the light-emitting diode (or semiconductor laser tube) and the axis of the phototransistor are on the same plane and form a certain angle, and the two axes intersect at a point in front of the sensor. When the surface of the detected object is close to the intersection, the reflected light of the light-emitting diode is received by the phototransistor, and an electrical signal is generated. When the object is far away from the intersection, the reflection area is not within the viewing angle of the phototransistor, and the detection circuit has no output. Under normal circumstances, the driving current sent to the light-emitting diode is not a direct current, but an alternating current of a certain frequency, so that the receiving circuit also obtains an alternating signal of the same frequency. If the received signal is filtered, only the signal of the same frequency is allowed to pass, which can effectively prevent the interference of other stray light, and can improve the luminous intensity of the light-emitting diode.

Proximity Sensor Advantages

① Since the detection can be performed in a non-contact manner, the detection object will not be worn or damaged.

② Since the non-contact output method is adopted, the life extension (except the magnetic type) adopts the semiconductor output, which has no influence on the life of the contact point.

③ Different from the light detection method, it is suitable for use in environments such as water and oil, and it is hardly affected by stains, oil, water, etc. of the detection object. In addition, Teflon shell type and products with good chemical resistance are also included.

④ Compared with contact switches, high-speed response can be achieved.

⑤ Compatible with a wide temperature range.

⑥ Detects changes in the physical properties of the detected object, which is not affected by the color of the detected object, so it is hardly affected by the surface color, etc.

⑦ Different from the contact type, it will be affected by the surrounding temperature, surrounding objects, and the same type of sensors. Therefore, for the setup of the sensors, mutual interference needs to be considered. In addition, in the inductive type, the influence of surrounding metal needs to be considered, while in the electrostatic capacitance type, the influence of surrounding objects needs to be considered.

Proximity Sensor Applications

Proximity sensors are mainly used to detect the displacement of objects, and are widely used in aviation, aerospace technology, and industrial production. In daily life, it also used for automatic doors and automatic hot air blowers of hotels, restaurants, garages,  have applications. In terms of security and anti-theft, important places such as data files, accounting, finance, museums, and vaults are usually equipped with anti-theft devices composed of various proximity switches. In the measurement technology, the measurement of length and position; in the control technology, such as the measurement and control of displacement, speed and acceleration, a large number of proximity switches are also used.

Tips to Sell Your Old Car

Published

on

No wonder selling a car privately is very frustrating and daunting. However, if you invest time and effort into it, the results will be worth it. Bear in mind, sellers who decide to sell an old car after much research can easily get a higher price. On the contrary, if they quickly sell it off to anyone who demands their vehicle in the first instance, the profit margin is less. Here, in this feature, we will shed light on the best tips to sell your old car:

  • Depersonalize It

One of the first things to do is to depersonalize your car and remove any personal touches that you have made. This not only implies that you have to get through the cleaning process but also give it a recent makeover. Sometimes, it is usually not cleanliness and a hygiene issue. It is more psychological because it will have an impact on the overall look of the car. You don’t want the other person to think of it as a product that will repulse the audience. 

  • Clean it Thoroughly

If you want to make the most out of your efforts, we recommend cleaning it thoroughly. Sometimes, thorough cleaning can help get the best price for your car. Cleaning a car is important because it will prepare it for the buyers before time. Therefore, as a seller, you need to inspect it thoroughly and see what changes need to be made. Sometimes, the interior is too untidy, and the buyer easily gets repulsed. So, as a rule of thumb, you need to clean it through and see how to make it look amazing. 

  • Be Careful of The surrounding When You Take Photos

Once you depersonalize your car, it will give it a much-needed look, but when you aren’t careful enough of the surroundings, it will have a negative impact on the vibe of the product. Sometimes, buyers lose the best-paying clients when the photos haven’t been taken in an attractive environment. Especially when you’re on the driveway or the street, you need to be extra cautious of everything, such as the people walking around, the garbage truck, or anything that could create disruption. 

  • Sell Your Car to Junk Services

If your old car is in a very bad condition and requires a hefty investment to come back to its normal shape, we recommend you sell it to cash for cars. After all, the junk services will pay you a good price for your current car, which will be better than the price offered by other platforms. Junk services have hands-on experience refurbishing many cars in the past, so they’ll offer you a good price if you’re looking for urgent cash. 

  • Be Honest About The Car’s condition

When it comes to the condition of your old car, honesty is the best policy. It might appear to be tempting to sell a vehicle if it is in good condition but equally frustrating for the buyer if the claims aren’t confirmed by their visit to your place. Always be upright and honest about your car’s condition and focus on the positive points.
