Silicone diaphragm, speaker module and method for reprocessing the silica gel diaphragm

Abstract

The invention discloses a silica gel diaphragm, a loudspeaker module and a method for reprocessing the silica gel diaphragm. The silica gel diaphragm adopts laser etching technology to etch two symmetrical line grooves on its surface; each line groove is A conductive metal layer is deposited, and the two ends of each conductive metal layer are provided with a first welding part and a second welding part. The first welding part is deposited on the plane part of the silicone diaphragm near the ring part, which is used for the voice coil The winding tap of the voice coil is welded on the inner side; the second welding part is deposited on the fixed part of the silicone diaphragm for welding the pad on the shell; the middle part connecting the first welding part and the second welding part is deposited in the silicone diaphragm Form a conductive path. The technical solution of the present invention can solve the problem of poor acoustics caused by the collision of the voice coil lead wires in the traditional solution, avoid the risk of voice coil lead wire breakage, and improve the acoustic performance and stability of the product; and the conductive metal layer deposited in the wire slot has a relatively high Good compactness, high uniformity, superior electrical conductivity.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a silicone diaphragm, a loudspeaker module and a method for reprocessing the silica gel diaphragm. Background technique [0002] The vibrating voice coil of a traditional moving coil speaker is composed of a voice coil body and a voice coil lead wire. The voice coil lead wire generally appears in two forms: first, the voice coil lead wire is adhered to the diaphragm, but this method easily causes the vibration system to be unbalanced. Polarization of the diaphragm is caused; secondly, the voice coil lead is suspended between the diaphragm and the casing, but this method has extremely high requirements on the radian and height of the voice coil lead and the symmetry of the positive and negative leads, otherwise the voice coil lead is easy to touch to the housing or diaphragm, resulting in poor acoustics. Moreover, when the speaker works in the high-power mode for...

Problems solved by technology

[0002] The vibrating voice coil of a traditional dynamic speaker is composed of a voice coil body and a voice coil lead wire. The voice coil lead wire generally appears in two forms: first, the voice coil lead wire adheres to the diaphragm, but this method easily causes the vibration system to be unbalanced. Polarization of the diaphragm is caused; secondly, the voice coil lead is suspended between the diaphragm and the casing, but this method has extremely high requirements on the radian and height of the voice coil lead and the symmetry of the positive and negative leads, otherwise the voice coil lead is easy to touch to the housing or diaphragm, causing acoustical problems

Moreover, when the above two methods work for a long time in the high-power mode, the vibrating voice coil and the voice coil lead wire are repeatedly bent, which may cause the potential risk of voice coil lead wire breakage, and the product stability is poor

[0003] In addition, the industry has plans to use electroplating or magnetron sputtering to form a conductive layer to replace the lead wire of the vibrating voice coil. However, due to the sparse arrangement of metal particles in the conductive layer formed by electroplating or magnetron sputtering, the resistance of the conductive layer itself is too high, The conductive layer is easy to fall off and other defects
