[0002] As shown in the accompanying drawings of the specification, Figure 4 The loudspeaker includes a stand, a magnetic circuit, a voice coil, a moving coil, a cone and a dust cap, the voice coil is fixed to the middle part of the moving coil and the lower end of the cone, the voice coil is inserted into the outer side of the T-shaped iron core of the magnetic circuit, the outer end of the moving coil is connected with the stand, and the dust cap is fixed to the middle part of the cone. The stand, the magnetic circuit, the voice coil, the moving coil, the cone and the dust cap form a relatively sealed cavity. When the voice coil is electrified, the moving coil vibrates, the vibration of the moving coil changes the volume of the cavity, thereby increasing or decreasing the air pressure in the cavity, so that the vibration of the moving coil is resisted or the cone is deformed additionally, thereby affecting the sound quality of the loudspeaker. The structure of other components of the loudspeaker except the stand is relatively simple, and the problem can only be solved from the stand, so a new type of stand is urgently needed. SUMMARY

[0003] The utility model aims at providing an improved loudspeaker stand, which can balance the air pressure in the cavity surrounded by the moving coil by setting the balance air hole, so as to ensure the normal vibration of the moving coil of the loudspeaker and improve the sound quality of the loudspeaker.

[0004] The above technical purpose of the utility model is realized by the following technical scheme:

[0005] An improved loudspeaker stand comprises an integrated voice coil former connecting boss and a structure reinforcing boss, the outer bottom surface of the voice coil former connecting boss is connected with the voice coil former, an annular groove is arranged between the voice coil former connecting boss and the structure reinforcing boss, the bottom of the annular groove is flat, and the inner side of the bottom of the annular groove is used for fixing the moving coil.

[0006] A plurality of balance air holes in communication with the annular groove are formed on the side wall of the voice coil former connecting boss. When the moving coil vibrates with the voice coil, the pressure generated in the cavity due to the volume change can be balanced through the balance air hole, so that the movement of the moving coil is not affected by the air pressure, thereby improving the sound quality of the sound.

[0007] A weight-reducing hole is formed on the structure reinforcing boss. By setting the weight-reducing hole, the appearance of the stand can be improved while the weight of the stand is reduced.

[0008] The utility model is further provided as follows: the weight-reducing hole is provided with a plurality of groups, and the plurality of groups of weight-reducing holes are circumferentially distributed, so as to further improve the appearance of the stand.

[0009] The utility model further sets up: each group of lightening hole includes multiple waist type holes of equidistance distribution;

[0010] The inner end of the waist type hole is formed with an inturned edge, which can improve the strength of the structure reinforcing boss and reduce the risk of deformation.

[0011] The utility model further sets up: the bottom outer edge of annular sink is formed with annular convex that section is semicircular, the setting of annular convex can enhance the overall strength of annular groove, also can carry out center positioning to the installation of elastic wave, make the position of elastic wave installation more accurate.

[0012] The utility model further sets up: the first end surface of structure reinforcing boss is not higher than the second end surface of washer connecting boss, and the air in the cavity surrounded by the elastic wave vibration can pass through the balance air hole and communicate with the annular sink, and the first end surface is lower than or equal to the second end surface, which can ensure that the air in the annular sink communicates with the atmosphere and ensures the smooth flow of air pressure.

[0013] The utility model has the advantages of:

[0014] Compared with the prior art, the balance air hole can make the internal cavity of the washer connecting boss communicate with the atmosphere, balance the air pressure in the cavity surrounded by the elastic wave in the loudspeaker, and ensure the normal vibration of the elastic wave in the loudspeaker, thereby improving the sound quality of the loudspeaker.

[0015] By setting multiple groups of lightening holes, the appearance and structural strength of the basin frame can be improved while reducing the weight of the basin frame. DRAWINGS
