Embodiment 1

[0037] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 with Figure 7 As shown together, a vibration speaker has a square structure and includes a housing 12, a front cover 11 and a rear cover 13 combined with the housing 12, and an inner cavity enclosed by the housing 12, the front cover 11 and the rear cover 13 contains a vibration system And the magnetic circuit system, the inner side wall of the housing 12 is provided with a shrapnel 42. The vibration system includes a diaphragm 21. The diaphragm 21 is combined with a voice coil 22. One end of the voice coil 22 is located in the magnetic gap formed by the magnetic circuit system. The system includes a basin frame 33. A magnet 32 ​​and a washer 31 are sequentially arranged in the basin frame 33. A magnetic gap is formed between the magnet 32 ​​and the washer 31 and the side wall 331 of the basin frame. The basin frame 33 has a square structure. The four corners of 331 are provided with notches 332; ...

Embodiment 2

[0043] Such as Figure 8 , Picture 9 , Picture 10 with Picture 11 As shown in common, the main difference between this embodiment and the first embodiment is:

[0044] The basin frame 33 has a racetrack-shaped structure, and two straight sides of the basin frame 33 are respectively provided with basin frame side walls 331.

[0045] The edge portion 422 of the shrapnel 42 is a square ring structure, the middle portion 421 of the shrapnel 42 is a racetrack-shaped ring structure corresponding to the shape of the basin frame 33, and the two straight-side edge portions 422 and the middle portion 421 are respectively provided There are two elastic arms 423; the bottom 411 of the counterweight 41 is a racetrack-shaped ring structure opposite to the shape of the basin frame 33, and the two opposite counterweights 41 are respectively provided with ear parts 412, and the ear parts 412 and The elastic arm 423 is located on the same side.

Embodiment 3

[0047] Such as Picture 12 , Figure 13 , Picture 14 with Figure 15 As shown in common, the main difference between this embodiment and the above embodiment is:

[0048] The vibrating speaker has a circular structure, and the basin frame 33, the shrapnel 42 and the counterweight 41 are all circular structures.

[0049] Three notches 332 are provided on the side wall 331 of the basin frame; three elastic arms 423 are provided between the edge portion 422 of the elastic sheet 42 and the middle portion 421 correspondingly; the counterweight 41 is provided with three side portions 413 and three side portions 413 They correspond to the positions of the three notches 332 respectively.

[0050] In this embodiment, the elastic sheet 42 is provided with three elastic arms 423, which correspond to the three notches 332 provided on the side wall 331 of the basin frame. This is only a preferred solution of the present invention. Two notches, two elastic arms are provided on the shrapnel; or ...

Abstract

The invention discloses a vibration loudspeaker and relates to the technical field of electroacoustic products. The vibration loudspeaker comprises a shell, a vibration system and a magnetic circuit system, wherein the vibration system and the magnetic circuit system are contained in the shell. An elastic sheet is arranged on an inner side wall of the shell. The magnetic circuit system comprises a basin rack. A magnet and a spring washer are sequentially arranged in the basin rack. A magnetic gap is formed between the magnet and the spring washer and the side wall of the basin rack. A notch is formed in the side wall of the basin rack. The elastic sheet comprises an edge portion fixed on the shell. An annular middle portion is arranged at the inner side of the edge portion. The edge portion is connected with the middle portion through an elastic arm. A side wall penetrates between the edge portion and the middle portion, so that the middle portion is located in the magnetic gap. A balance weight matched with a structure of the magnetic circuit system is arranged on the middle portion. The vibration loudspeaker solves the problems that a vibration loudspeaker in the prior art is large in size and can not satisfy the requirement for portable electronic terminal microminiaturization development. The vibration loudspeaker has the advantages of being small in size, stable in work performance, capable of fully satisfying the requirement for portable electronic terminal microminiaturization development and the like.

Description

Technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a vibration speaker. Background technique [0002] The vibrating speaker is a multifunctional acoustic device. In addition to realizing the vibration and sound function of an ordinary speaker, it also has the function of a vibration motor. The vibrating speaker can save the internal space of the portable electronic terminal, simplify the assembly process of the portable electronic terminal, and reduce the cost of the portable electronic terminal. Therefore, the vibrating speaker is more and more widely used in the field of portable electronic terminals. [0003] The structure of the vibrating speaker in the prior art mainly includes a housing, and a vibration system and a magnetic circuit system arranged in the housing. The magnetic circuit system includes a washer, a magnet, and a basin frame combined in sequence, and the vibration system includes a combined diaphragm ...
