Embodiment
Below in conjunction with accompanying drawing, execution mode of the present utility model is elaborated.It is emphasized that following explanation is only exemplary, instead of in order to limit scope of the present utility model and application thereof.
Consult Fig. 1 a to Fig. 3 c, according to embodiment of the present utility model, a kind of Wristwatch case structure with electroacoustic device comprises housing 5, the inner side of housing 5 offers the first containing cavity 8, namely the second containing cavity 7 is offered, the piezoelectric ceramic loudspeaker 1 that electroacoustic device comprises base plate 2 and fixes on a base plate 2 bottom it in first containing cavity 8.Base plate 2 is placed in the first containing cavity 8, piezoelectric ceramic loudspeaker 1 to embed in the second containing cavity 7 and and the bottom of the second containing cavity 7 there is interval R, the distance of this interval R, at 0.1mm-0.4mm, is preferably 0.15-0.25mm, is more preferably 0.2mm.Through test, preferred spaced design can obtain splendid loud speaker voice effect.The floor space of the first containing cavity 8 is greater than the area of base plate 2, in the clearance spaces of the first containing cavity 8 (namely between the chamber wall of the first containing cavity 8 and base plate 2 periphery) injection moulding with make base plate 2 and piezoelectric ceramic loudspeaker 1 one-body molded on housing 5.Injection article can be plastic material or the silica gel etc. such as PC, AB or PC+ABS.
Greatly simplifie the structure of loud speaker in equipment by one-body molded in housing for piezoelectric ceramic loudspeaker, reduce the space hold in equipment, avoid due to loud speaker thickness and have influence on complete machine thickness greatly.In addition, piezoelectric ceramic loudspeaker 1 is arranged in the first containing cavity, inwall relatively near housing 5 also has certain intervals with it, on the one hand, good vibrating vocal cavity effect can be formed, on the other hand, piezoelectric ceramic loudspeaker in follow-up assembling process also can be avoided to contact with miscellaneous part in housing and damage, more can prevent from being contacted by mould in technical process shaping on housing 5 and damaging.
The area of base plate 2 can be less than or equal the accent area of the second containing cavity 7.More preferably, the area of base plate 2 is greater than the accent area of the second containing cavity 7 and a part for base plate 2 is pressed together on the step surface around the second containing cavity 7 in the first containing cavity 8.In a more preferred embodiment, base plate 2 can have the profiled edge 3 being with multiple breach, namely base plate 2 periphery at least partially in irregular form, the lower surface of profiled edge 3 is pressed together on the step surface 6 around the second containing cavity 7 in the first containing cavity 8, injection moulding in the space between profiled edge 3 and the chamber wall of the first containing cavity 8.The profiled edge 3 of preferred versions can comprise the notch that oral area is less and inside is wider, and this notch structure is conducive to after being filled with injection article, make profiled edge 3 firmly fix.Step surface 6 can be the smooth chamber wall extending to the first containing cavity 8, and now injection article is filled on the step surface 6 between profiled edge 3 and the chamber wall of the first containing cavity 8.Another kind of mode is, groove is formed between step surface 6 and the chamber wall of the first containing cavity 8, now injection article is filled in a groove (profiled edge 3 takes whole step surface 6), or to be filled on the step surface 6 between profiled edge 3 and the chamber wall of the first containing cavity 8 among (profiled edge 3 does not take whole step surface 6) and groove.As previously mentioned, profiled edge 3 may take whole step surface 6, now the shape of step surface 6 and the mating shapes of profiled edge 3.In addition, step surface 6 can arrange positioning convex 10, and profiled edge 3 can offer the location hole 9 matched with positioning convex at correspondence position, facilitate the noseplate 2 of injection moulding to install with the contraposition of housing.
