Problems solved by technology

[0002] Current headphone equipment usually uses a magnet under the sound film to interact with a magnetic field generated by a set of concentric voice coils that input audio current. The voice coil drives the sound film to vibrate to generate sound waves. Due to the small contact area between the voice coil and the sound film, distortion is easily generated.
I applied for the magnetic diaphragm of earphones in 2012, which belongs to the magnetic diaphragm of earphones for moving iron earphones. The invention patent publication number is CN 103297899 A. It only makes technical innovations on the magnetic diaphragm of earphones, but the magnetic diaphragm does not have any effect on the audio current. Converted to a uniform magnetic field for design

Embodiment Construction

[0017] Such as figure 1 As shown, there is a permanent magnet 103 on the magnetic diaphragm 102 of the moving iron earphone 101 . There is a sound film support 104 on the magnetic diaphragm 102 , and the sound film support 104 plays a role of fixing the magnetic diaphragm 102 . Under the magnetic diaphragm 102, there are multiple voice coils and a voice coil group composed of a magnetic conductor, such as a voice coil group composed of a voice coil 107 and a magnetic conductor 108, a voice coil group composed of a voice coil 110 and a magnetic conductor 111, and a voice coil 114. and a voice coil set composed of a magnetic conductor 113. The voice coils are connected through wires, for example, the voice coil 107 is connected to the voice coil 110 through the wire 109 , and the voice coil 110 is connected to the voice coil 114 through the wire 112 . The magnetizers 108 , 111 , 113 are at the same distance from the magnetic diaphragm 102 . The moving iron earphone housing 10...

Abstract

The invention relates to a moving-iron headset, in particular to a layout method of voice coil groups of the moving-iron headset. According to the layout method, more than three voice coil groups consisting of voice coils and magnetic conductors are arranged, wherein all the voice coil groups are uniformly distributed below a magnetic vibrating diaphragm. Under the magnetic vibrating diaphragm, a voice frequency current drives multiple groups of voice coils to generate a magnetic field, so that the surface of the magnetic vibrating diaphragm is uniformly stressed, and the generated sound wave is little in distortion, large in dynamic condition and sensitive in response.
