Compared with the relevant technologies, the fixation wall of the steel disc is arranged to by the master by the loud speaker of the utility model The main wall and the reinforced wall extended by main wall both sides that body portion extends, so that the fixation wall is in dovetail wide outside and narrow inside Shape structure, which makes the fixation wall be embedded at the frame fixing intensity bigger of the latter two, not easily to fall off, and then makes The acoustical behavior for obtaining the loud speaker is more stable.

【Description of the drawings】

It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings Other attached drawings are obtained, wherein：

Fig. 1 is the part isometric structural decomposition diagram of the utility model loud speaker；

Fig. 2 is the structural decomposition diagram of the upper cover of the utility model loud speaker.

【Specific implementation mode】

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The all other embodiment obtained, shall fall within the protection scope of the present invention.

Please refer to Fig. 1-2, wherein Fig. 1 is the part isometric structural decomposition diagram of the utility model loud speaker；Figure 2 be the structural decomposition diagram of the upper cover of the utility model loud speaker.The utility model provides a kind of loud speaker 100, including Frame 1, vibrational system 2, magnetic circuit system 3 and upper cover 4.

The vibrational system 2 and the magnetic circuit system 3 are individually fixed in the frame 1, and the upper cover 4 is covered on the basin On frame 1.

The vibrational system 2 includes the voice coil 22 for being fixed on the vibrating diaphragm 21 of the frame 1 and the vibrating diaphragm 21 being driven to vibrate. Electromagnetic field is generated jointly with the magnetic circuit system 3 after the energization of the voice coil 22 so that the voice coil 22 moves back and forth, and then drives 21 vibration sounding of the vibrating diaphragm.

The upper cover 4 include pressure set on the frame 41 annular in shape of the vibrating diaphragm 21 and be covered on the frame 41 and with institute State the steel disc 42 that frame 41 is fixedly connected.

In present embodiment, the steel disc 42 is integrated injection molding with the frame 41.

Specifically, the steel disc 42 includes main part 421, goes out acoustic aperture 422 and by institute through what the main part 421 was arranged State the outwardly extending fixation wall in side 423 of main part 421.

It is described go out acoustic aperture 422 be oppositely arranged with the vibrating diaphragm 21 for speaking, shape is unlimited with quantity.

The fixation wall 423 includes multiple and surrounds 421 spaced setting of the main part.The fixation wall 423 is embedding Set on the frame 41, so that the steel disc 42 is fixed on the frame 41.

More preferably, the fixation wall 423 and 421 shape of the main part it is in 90 °~180 ° of angle.The fixation wall 423 Arc-shaped structure.Combined with firmness higher when the structure makes the fixation wall 423 be embedded in the frame 41.

In present embodiment, the main part 421 is an integral molding structure with the fixation wall 423, i.e. the steel disc 42 It is integral structure.

In present embodiment, for the steel disc 42 for rectangular, every side of the steel disc 42 each extends over setting two A fixation wall 423, i.e., the described steel disc 42 include eight fixation walls 423.Certainly, the shape of the steel disc 42 and described The quantity of fixation wall 423 is not limited to this.

In present embodiment, the fixation wall 423 includes the body wall 4231 extended by the main part 421 and by described The reinforced wall 4232 that the both ends of body wall 4231 each extend over.

For example, above structure makes the cross-sectional area of the fixation wall 423 by its side far from the main part 421 It is gradually reduced to a side direction of its close main part 421.

That is, after 423 structure of the fixation wall makes it be embedded at the frame 41, the reinforced wall 4232 is suitable In formed limiting card be provided as using, to strengthen the fixing intensity of the fixation wall 423, that is, strengthen the steel disc 42 with it is described The fixing intensity of frame 41.

Therefore, in present embodiment, on the one hand, the steel disc 42 is high with 41 fixing intensity of the frame, even if described The enclasping force formed in the case that frame 41 is small-sized also can reach 30N or more so that the reliability of the loud speaker 100 By force；On the other hand, because the bond strength of the steel disc 42 and the frame 41 is high, then the upper cover 4 can minimize the side The size of frame 41, and so that the size of the steel disc 42 increases as far as possible, to increase the young modulus of the upper cover 4 or strong Degree, and then improve the acoustical behavior of the loud speaker 100.

Compared with the relevant technologies, the fixation wall of the steel disc is arranged to by the master by the loud speaker of the utility model The main wall and the reinforced wall extended by main wall both sides that body portion extends, so that the fixation wall is in dovetail wide outside and narrow inside Shape structure, which makes the fixation wall be embedded at the frame fixing intensity bigger of the latter two, not easily to fall off, and then makes The acoustical behavior for obtaining the loud speaker is more stable.

Above-described is only the embodiment of the utility model, it should be noted here that for the ordinary skill of this field For personnel, without departing from the concept of the present invention, improvement can also be made, but these belong to this practicality Novel protection domain.
