To solve the above-mentioned problems, the purpose of the utility model is to provide a kind of safe to use, facilitate production, structure simple Single multi-functional micro-vibration loudspeaker.

In order to achieve the above objectives, the technical solution of the utility model is as follows：A kind of micro-vibration loudspeaker, the loudspeaker are by preceding Lid, diaphragm, voice coil, holder, washer, magnet, U glasss, vibrating reed, quality loop, rear cover composition, the holder is cylinder, intermediate Three sections of arc convex I, two sections of arc convex II are distributed on the lower face of holder in through-hole；Described raised II with raised I phase It connects, forms a groove between them for gluing fixed rear cover；The rear cover is installed on the bracket, by described raised I Support；Described raised II is equipped with an inclined-plane, convenient for the fixed rear cover of gluing；Two are additionally provided on the lower face of the holder to determine Position protrusion；The positioning protrusion is symmetric；The positioning protrusion is equipped with inclined-plane, convenient for the fixed rear cover of gluing；Institute It states and is additionally provided with positioning plate on positioning protrusion, for rear cover described in location and installation；The rear cover uses stainless steel；The rear cover It is in disk form, it is provided with one section of arc notch thereon；Arc between the arc length of the arc notch and the positioning plate of two positioning protrusion Length is equal.

Further, the tin plating stainless steel weld tabs of two panels is additionally provided on the pedestal lower end face；The tin plating stainless steel weld tabs note At the lower end of the stand in face, surface is less than the lower face of holder for modeling.

Further, the vibrating reed is installed on the bracket；The magnet, is sequentially arranged in U glasss described washer； Described U glasss is fixed on the vibrating reed；The quality loop is mounted on the vibrating reed；The rear cover is adhesive in the holder Lower face on；The diaphragm is mounted on the upper surface of the holder；The voice coil is sticked on the diaphragm, is set in institute It states on magnet；The protecgulum gluing is on the upper surface of holder.

The utility model has the beneficial effects that：(1) the utility model rear cover is provided with one section of arc notch and fundamentally solves Conducting wire stripping head contacts the problem for short circuit occur with stainless steel rear cover, uses safer；(2) the utility model uses tin plating Stainless steel weld tabs is moulded in the mode of the traditional attaching pcb board of substitution in holder, greatly improves production efficiency, makes simultaneously Whole horn structure is more compact, and product is more stablized；(3) the utility model be equipped with protrusion II and protrusion I, after cover Glue is easy to operate when installing, efficient, while ensureing that glue will not fall on trumpet core component, stable quality.(4) originally Utility model integrates vibration, receiver, microphone, compact-sized, powerful.
