Description

Speaker structure improvement

The invention relates to a speaker structure improvement, in particular to a speaker structure applied to a micro horn and having a blast wave disposed inside the voice coil, and the elastic wave system is a high and low slant wave structure for vibrating the voice coil When you make a sound, you can increase its bass performance.

In general, the horn is usually provided with a spring wave structure for the diaphragm to reciprocate in the axial direction. Generally, the horn usually includes a bracket, a yoke, a magnet, a washer and a voice coil. The snare is provided with a elastic wave structure, so that when the voice coil vibrates, the elastic wave structure can be used to prevent the voice coil from being displaced and colliding with the yoke, the magnet or the washer to avoid the occurrence of abnormal sound or the damage of the horn. However, in order to cope with the development of today's technology, thinning will be an inevitable trend. If the speaker is to be placed on a thinner device, the speaker must use a thin speaker, and the thin speaker is set to a bomb wave because of its height. It is difficult to connect the structure to the voice coil. Therefore, the manufacturer must make a decision to sacrifice the structure of the elastic wave in exchange for the reduction of the overall height, but lose the structure of the elastic wave. In addition to the inability to locate the voice coil, it will cause distortion of the sound quality. The problem occurs, especially when the space for reciprocating the diaphragm is increased, the vibration of the diaphragm will easily occur to collide with other components inside the horn, which will result in Situation as abnormal noise or cause damage and affect the sound quality of the monomer occurs.

Since the thin speaker has no elastic structure, the performance is limited. Therefore, the manufacturer chooses to set the elastic wave structure inside the voice coil. As shown in FIG. 1, the speaker 1 has a housing 11, a magnet 12, a voice coil 13, and a bullet. The wave 14, the diaphragm 15, the dust cover 16 and the heat insulating material 17, and the elastic wave 14 is disposed inside the voice coil 13, such a manner that the volume of the speaker 1 can be reduced (wide) At the same time, the voice coil 13 can be positioned to avoid the occurrence of abnormal sound or horn damage due to the collision; however, in the above-mentioned embodiment, one end of the elastic wave 141 is adhered to the voice coil 13, and the elastic wave is different. One end 142 is adhered to the heat insulating material 17, but as shown in FIG. 1, the bonding surface of the elastic wave end 141 and the voice coil 13 and the bonding surface of the elastic wave end 142 and the heat insulating material 17 are actually very Unstable, when the voice coil 12 vibrates, the elastic wave 14 is likely to fall or break; in addition, since the speaker 1 is assembled, the operator must first place the elastic wave 14 on the voice coil 13 and Between the heat insulating materials 17, the bonding surface of the acoustic wave 14 and the voice coil 13 and the heat insulating material 17 is bonded, but due to the structural limitation, it is difficult for the operator to smoothly bond, and if the bonding action is not correct, once When the voice coil 13 vibrates, the elastic wave 14 is likely to be shaken and dropped due to poor adhesion. Such a structure will cause difficulty in implementation, so even if the problem that the thin speaker has no elastic structure can be solved, However, due to implementation and industry use, it is not practical. There are very big problems need to be improved.

Therefore, if the elastic wave can be disposed inside the voice coil, one end of the elastic wave can be disposed on a Chinese machine, and a positioning member is disposed on one end of the elastic wave to position one end of the elastic wave to the positioning member and the washer. Between the other end, the other end of the elastic wave is positioned by the diaphragm, the hanging edge and the top of the voice coil to position the other end of the elastic wave between the hanging edge and the top of the voice coil. Therefore, the stacking method can be used. The component is superimposed on the elastic wave, that is, a part of the surface of the component may be adhered to the surface of the elastic wave to fix the elastic wave, and the occurrence of falling due to a single point of adhesion may be avoided, so For an optimal solution.
