Company Information

We Are a professional loudspeaker manufacturer with almost two decades experience in the scope. It developed from a small workshop 20 years ago.It has growing to be an professional manufacturer of car speaker. Our main products include Multimedia speaker,coaxial car speaker,tweeter,midrange,subwoofer,PA speaker,Portable voice amplifier,and speaker parts.

T iron & washer:

1) Play the role of fixing the magnet and the basin frame

2) A uniform magnetic flux loop is formed between the magnetic rigidity and the T iron. The design of the T iron heat dissipation hole will affect the heat dissipation of the voice coil, and the gap between the magnetic rigidity and the T iron will affect the efficiency of the voice coil.

magnetic steel:

1) The materials used generally include AlniCo, Neodymium, and Ferrite. Among them, AlniCo has the highest magnetic flux density, followed by neodymium, and then ferrite.

2) Magnetic flux density is the abbreviation of magnetic flux density. It reflects the density of magnetic lines of force in quantity, that is, the strength of the magnetic field. The higher the magnetic flux density, the stronger the magnetic field, and the more fidelity the speaker can restore the sound. high.

 Basin frame:

1) The basin frame is mainly made of iron sheet, cast aluminum or plastic.

2) When the rigidity of the basin frame is not good, the speaker will resonate when it is working, which will cause peaks or valleys in the frequency response and cause sound distortion.

3) Poorly designed basin frame structure will affect the airflow generated by cone vibration, and the reflection of sound waves in the basin frame will affect the quality of the restored sound.

Cone:

1) It is the most important vibration component in the speaker unit, which directly drives the air and converts the mechanical motion of the speaker unit into sound wave vibration of the air.

2) It directly determines the performance of all aspects of the unit's replay sound, such as frequency response, distortion, sensitivity, etc.;

3) The commonly used materials are mainly paper, glass fiber, carbon fiber, polypropylene, etc.

Bouncing:

1) The main purpose is to provide restoring force for the movement of the cone, and to keep the voice coil in the correct position in the magnetic gap during movement.

2) It can also prevent foreign objects from falling into the magnetic gap. Its performance greatly affects the mid-low frequency playback effect of the speaker unit; together with the cone, the folding ring and the voice coil, it determines the quality of the speaker unit.

3) Generally, cloth woven with cotton, linen, polyimide, Nomex and other fibers, and then impregnated with resin to make it shape (wave-shaped) and harden.

Voice coil:

1) It is the central component of the speaker unit's sound, which obviously affects the sound performance of the speaker unit.

2) According to the relationship between the width of the voice coil winding and the height of the magnetic gap, it is generally divided into a long voice coil structure and a short voice coil structure. The coil material generally uses round copper wire, aluminum wire, etc.

Folding ring:

1) Provide a certain degree of compliance for the movement of the cone, and have a certain flexibility, so that the cone can vibrate up and down.

2) The auxiliary elastic wave locates the cone voice coil, keeps the voice coil in the center of the magnetic gap, and provides the restoring force of the cone movement.

3) The commonly used materials mainly include leather, rubber, plastic, etc.

Dust cover:

1) Prevent foreign objects from falling into the magnetic gap and affecting the movement of the voice coil

2) Isolate the air in the front and back of the cone to avoid the sound radiated backwards going to the front, which mainly affects the middle and high frequencies.
