Products Description

The speaker coil is a device that converts electrical signals into mechanical vibrations, and is an important component of the mechanical wave system of an electric speaker. It can also be said to be the heart of the speaker. Its function is to produce horn sound.

During the operation of the speaker, the voice coil is responsible for the power part of the speaker. When powered on, it becomes an electromagnet that exerts a force on the permanent magnet. The force changes according to the current, causing the sound film to vibrate. The stroke length, air force, speed, and other factors of a voice coil can all affect the sound quality.

The difference between different diaphragms

Titanium diaphragm: a common high-frequency diaphragm on the market, with high cost-effectiveness and clear and bright sound quality.

Blue film: Apply a layer on the surface of the titanium film, which solves the problems of burrs and auditory fatigue caused by the titanium film, and the sound quality is more durable.

Composite film: Polymer composite film is an innovative material that has a finer and more durable sound quality compared to titanium film and blue film. After pressing the film, it can instantly recover, effectively avoiding the situation of film rupture.

Horn tips

The speaker unit of high school bass has different requirements for the voice coil, and how to select the voice coil parameters within the specified size range can produce greater value.

The voice coil of the tweeter is relatively thinner, and the two materials commonly used are copper wire and aluminum wire. Applied to the voice coil of the tweeter horn, aluminum wire is lighter than copper wire, and can obtain better transient response. The resistance of copper wire is smaller, and aluminum wire is less than copper wire in terms of endurance and durability.

Mezzo and subwoofer voice coils are often wound with copper wire, because the copper wire is thicker and can withstand high power. Some subwoofers on the market will choose to wind several layers of voice coil in order to increase the bearing capacity.

The general voice coil is wrapped around the paper tube, but the paper is not a good conductor of heat, but has the advantage of light weight. In order to improve the heat dissipation efficiency, some speakers will wind the voice coil on the aluminum tube, the heat dissipation effect is significantly improved than the paper tube, and the bearing capacity is also significantly improved.

Voice coil functions Common faults occur

1, manufacturing process problems: the speaker voice coil may have process defects in the manufacturing process, such as uneven winding of the coil, the coil wire diameter is too thin or too thick, resulting in unstable mechanical strength and electrical performance of the voice coil.

2, the use of poor environment: the speaker may be affected by the environment during use, such as too high or too low temperature, excessive humidity, excessive dust, etc., these factors may lead to the aging and damage of the voice coil.

3, the current is too large: when the current input to the speaker is too large, it will cause the voice coil to overheat or even burn.

4, mechanical vibration: the speaker will be affected by mechanical vibration during use, such as the impact of the speaker or the vibration is too large, which may cause the voice coil to shift or fall off.

5, improper maintenance: The speaker in the use of the lack of proper maintenance and maintenance, such as improper cleaning, the use of inappropriate detergent, etc., may lead to corrosion or damage to the voice coil.

6, contact ablation: If you press the miniature horn for a long time, it is easy to appear horn contact ablation and generate impedance. The current flowing through the electromagnetic coil is weakened, the electromagnetic suction is reduced, and the armature cannot be attracted to drive the normal vibration of the diaphragm, resulting in hoarse or even no sound. There are also cases when the horn is constantly honked, there is a momentary strong current through the impedance during the press, it will work normally, when the current ends will not continue to work, there are good and bad conditions.

7. The sealing gap causes moisture: although the inside of the miniature horn is sealed, if the seal is not tight, the water vapor or fog in the air will enter the car wash, and the contact will not work properly because of moisture.

Select speakers and routine maintenance measures

1. Choose high-quality and reliable speaker products: Choosing well-known brands and speaker products with quality assurance can reduce the incidence of voice coil failures.

2. Pay attention to the usage environment: Keep the speaker usage environment clean and dry to avoid damage to the speaker caused by high and low temperatures.

3. Correct use and maintenance: Avoid excessive or improper use of speakers, and regularly perform appropriate maintenance and upkeep, such as cleaning, checking screws and glue, etc.

4. Regularly replacing the voice coil: For speakers that have been in use for a long time or have malfunctioned, regularly replacing the voice coil can extend the lifespan of the speaker and improve sound quality performance.

5. Professional maintenance: When the speaker malfunctions, seek the help of professional maintenance personnel to avoid further damage caused by self disassembly.
