Detailed description of the invention

For describing speaker modular structure of the present utility model in detail, new to this practicality below with reference to accompanying drawing The specific embodiment of type is described in detail.

Fig. 1 shows the decomposition texture of the speaker module according to this utility model embodiment.

As it is shown in figure 1, the speaker module of this utility model embodiment, including module casing and collecting Loudspeaker monomer 3 in the cavity that module casing is formed, wherein, is provided with leakage mouth on module casing 6；Wherein, it is provided with spring washer 4 revealing at mouth 6, spring washer 4 is provided with and reveals mouth 6 position phase Corresponding perforate, the tapping at spring washer 4 is pasted with screen cloth 5, by adjusting the size and location of perforate, Control to reveal the size of the leakage rate of mouth 6, finally realize the impact on speaker acoustical behavior.

Wherein, module casing includes module mesochite 2 and the module upper casing 1 suitable with module mesochite 2 With module lower casing 7, being provided with accepting groove on module mesochite 2, loudspeaker monomer 3 is fastened in accepting groove, The cavity that module casing is formed is divided into the front operatic tunes and the rear operatic tunes by loudspeaker monomer 3, and the front operatic tunes passes through mould The side of group upper case side wall goes out acoustic aperture and connects with external environment, and the rear operatic tunes is confined space；After making the front operatic tunes And the air pressure balance between the rear operatic tunes, it is to avoid draught head produces impact to vibrating diaphragm, in the side of module mesochite 2 Being provided with leakage mouth 6 on wall, the rear operatic tunes is by revealing mouth 6 and extraneous conducting.

Groove, circular leak holes is revealed it should be noted that leakage mouth of the present utility model can be strip Or leakage device in irregular shape etc., it is possible to after realizing speaker module, the operatic tunes all may be used with extraneous conducting.

In speaker module of the present utility model, reveal the end that mouth 6 is arranged on the sidewall of module mesochite 2 On face, being provided with spring washer 4 revealing at mouth 6, the position of opening of spring washer 4 is corresponding with revealing mouth 6, logical The corresponding relation crossing the perforate adjusting spring washer 4 and reveal mouth 6 area, and adjust the size of perforate, can With the hole size of the operatic tunes after controlling with extraneous conducting, and then adjust the leakage rate of speaker, it is achieved raise one's voice The variation of device acoustic efficiency.

It should be noted that in a specific embodiments of the present utility model, spring washer 4 can pass through Gluing it is fixed on module casing, it is of course also possible to realize the fixing of the two by the way of other are different, It is not particularly limited at this.Such as, when spring washer is fixed at leakage mouth 6 by the mode such as gluing, pin To different size or the product of requirement, different size of perforate, then joining at screen cloth 5 can be set Under conjunction, it is achieved to the adjustment revealing mouth 6.When spring washer is fixed on mould by movable connection methods such as pull grooves Time on group housing, can be set to irregularly shaped by revealing mouth 6, by changing spring washer 4 and revealing mouth 6 Relative position, i.e. the size of operatic tunes leakage rate after adjustable.

Understand, for the fixed form of the spring washer 4 that above-mentioned this utility model is proposed, it is also possible to do not taking off Various improvement is made on the basis of this utility model content.

In another detailed description of the invention of the present utility model, the tapping at spring washer is sticked screen cloth 5, passes through Change the mesh number of screen cloth 5, can realize the adjustment revealing mouth 6.Additionally, screen cloth 5 can not only reduce Reveal mouth 6 on product acoustics should be able to impact, it is also possible to stop the small particles of pollution thing in air to enter and raise Sound device module internal, so that it is guaranteed that speaker module tonequality in use and acoustical behavior thereof.

Specifically, Fig. 2 shows that the plan structure of the speaker module according to this utility model embodiment is another Fig. 3 shows the partial enlargement structure of part A in Fig. 2.

As Fig. 1 to Fig. 3 jointly shown in, the speaker module of this utility model embodiment, reveal mouth 6 be Strip structure, the perforate of spring washer 4 is arranged on the one end revealing mouth 6, spring washer 4 and the shape of screen cloth 5 Shape and position are suitable with the shape of leakage mouth 6 and position.By adjust spring washer 4 perforate size or The size of mouth 6 and extraneous conducting is revealed in person's position control, in other words, reveals leakage rate and the perforate of mouth 6 Area and the mesh number of screen cloth 5 interrelated.

In another detailed description of the invention of the present utility model, loudspeaker monomer 3 includes vibrational system and magnetic Road system；Wherein, vibrational system includes vibrating diaphragm and is fixed on the voice coil loudspeaker voice coil of vibrating diaphragm side；Magnetic circuit system bag Include conductive magnetic yoke, be fixed on the conductive magnetic yoke Magnet near vibrating diaphragm side, and be arranged on Magnet away from conductive magnetic yoke The washer of side.Wherein, washer can use permeability magnetic material, is used for revising the magnetic line of force；Conductive magnetic yoke is arranged on Between washer, Magnet and loudspeaker monomer shell, use the material of high magnetic conduction to be made, use process In be fixed on loudspeaker monomer shell by gluing or fixing post, the effect of heat radiation can be played, it is to avoid During magnetic circuit system work, temperature is too high, it is ensured that the acoustical behavior of speaker module is stable.

By above-mentioned embodiment it can be seen that this utility model provide speaker module, by change The mesh number of the size of the perforate on spring washer, position or screen cloth, it is possible to adjust speaker module reveal mouth with The area of extraneous conducting, so that speaker has multiple acoustic efficiency, improves the acoustics of speaker product Energy.

Describe in an illustrative manner above with reference to accompanying drawing according to the speaker module that the utility model proposes. It will be understood by those skilled in the art, however, that the speaker module that above-mentioned this utility model is proposed, Various improvement can also be made on the basis of without departing from this utility model content.Therefore, this utility model Protection domain should be determined by the content of appending claims.
