Embodiment
A kind of mini audio, comprise housing, is fixed on loudspeaker and the circuit board of enclosure interior, also comprises that one is arranged on the vibrating membrane of described loudspeaker rear side, closely cooperates between described vibrating membrane and housing.The present invention is because the rear side at loudspeaker is provided with vibrating membrane, and vibrating membrane has the effect that improves loudspeaker bass and resonance effect, improve to a certain extent the tonequality of mini audio, thereby made mini audio send preferably tonequality, can give a kind of enjoyment acoustically of people.
The invention will be further described below in conjunction with accompanying drawing and preferred embodiment.
As Figure 1-4, mini audio 1 comprise housing and be fixed on loudspeaker, the battery circuit board of enclosure interior and be fixed on loudspeaker and circuit board between vibrating membrane 5.Vibrating membrane 5 can improve the vibrating effect of sound, thereby improves the tonequality of mini audio 1.
Generally, 5 ones of vibrating membranes are to be made by soft materials, and housing adopts, mostly be duroplasts or metal material, if will be directly fixing between the two, vibrating membrane 5 may come off or fixing illusive situation so, and in order to solve this situation, mini audio 1 also comprises a vibrating membrane fixed frame 6, vibrating membrane 5 is fixed on vibrating membrane fixed frame 6, then vibrating membrane fixed frame 6 is fixed in housing.The vibrating membrane adapted with vibrating membrane 5 shapes that vibrating membrane fixed frame 6 comprises the housing 61 adapted with housing and is arranged on housing inside is dodged hole 62, interference fit between housing 51 and housing, vibrating membrane is dodged between hole 62 and described vibrating membrane 5 and is closely cooperated, so just can be so that seamless contact the between vibrating membrane 5 and vibrating membrane fixed frame 6, and seamless contact the between vibrating membrane fixed frame 6 and housing.
Vibrating membrane 5 is round pie, on vibrating membrane 5, be provided with a recessed annular recess 51, corresponding vibrating membrane is dodged hole 62 and is circular, and the internal diameter that vibrating membrane is dodged hole 62 equals the diameter of described vibrating membrane 5, at vibrating membrane, dodge on the rim in hole 62 and be provided with the annular platform 63 that is less than vibrating membrane 5 diameters to projecting inward and internal diameter; The external diameter of annular recess 51 is identical with the internal diameter of annular platform 63.As long as the vibrating membrane 5 of annular recess 51 outsides is applied glue and is bonded together and just vibrating membrane can be fixed on vibrating membrane fixed frame 6 with annular platform 63.Annular platform 63 is positioned at 1/2 At The Height that vibrating membrane is dodged 62 edges, hole, the whole inside that just is in vibrating membrane fixed frame 6 of vibrating membrane 5 like this, and vibrating membrane 5 is by softer material, to be made easily to be damaged, can in installation process, protect and expand vibrating membrane 5, thus the damage rate of reduction product.The total height of housing 61 equals the height that vibrating membrane is dodged hole 62, and the end of housing 61 and described vibrating membrane are dodged 62De end, hole and be positioned at sustained height.It is identical that housing 61 and vibrating membrane are dodged empty 62 height, when not increasing vibrating membrane fixed frame 6 and taking the volume of enclosure interior, can increase again the fixedly contact area of vibrating membrane fixed frame 6 and housing.In order to alleviate the weight of mini audio 1, at housing 62 and vibrating membrane, dodge between hole 52 to be provided with and draw the glue lightening hole.
Between circuit board and loudspeaker, be connected by wire, vibrating membrane 5 is fixed in the housing between loudspeaker and circuit board, on vibrating membrane fixed frame 6, is provided with wire and dodges hole (not marking in figure), facilitates wire to pass through vibrating membrane fixed frame 6.
Housing is the square shape, and housing 61 also is the square shape, and the external diameter of housing 61 equals the internal diameter of described housing, and the internal diameter of described housing 61 equals the external diameter that described vibrating membrane is dodged hole 62; Vibrating membrane fixed frame 6 use glue are fixed on described enclosure interior.Adopt glue fixedly vibrating membrane fixed frame 6 not only can fixedly secure vibrating membrane fixed frame 6, and glue can also fill the gap between vibrating membrane fixed frame 6 and housing, guarantees that further vibrating membrane 5 improves the effect of tonequality.
On circuit board, be provided with the usb interface be connected with external usb data wire, the corresponding usb interface that arranges on housing is dodged hole.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, section should be considered as belonging to guarantor of the present invention and expand scope.
