Description

Minitype acoustic generator

[technical field]

The utility model relates to a kind of minitype acoustic generator, relates in particular to a kind of minitype acoustic generator that is applied on the portable consumer electronic products such as mobile phone.

[background technology]

Minitype acoustic generator is widely used in portable electronic equipments such as mobile phone, notebook computer, hearing aids.Along with the fast development of these portable electronic equipments, people are more and more stronger to its functional requirement, the also corresponding development apace of the mini-sound device that is applied thereon.

The minitype acoustic generator of dependency structure mainly comprises support that has pad end and shell fragment portion and the voice coil loudspeaker voice coil that has voice coil line, voice coil line on the voice coil loudspeaker voice coil and the welding of the pad end on the support, and the shell fragment position on the support connects external circuit.The minitype acoustic generator that adopts this method to make, the rack forming process operation of band shell fragment portion is many, and assembling back shell fragment portion can not reach with support and well combines fastness.

Thereby, be necessary to study a kind of minitype acoustic generator with new construction.

[utility model content]

The purpose of this utility model is to provide that a kind of die molding process operation is few, have preferably the minitype acoustic generator in conjunction with fastness after the assembling.

For solving the problems of the technologies described above, the technical scheme that the utility model provides is:

A kind of minitype acoustic generator, it mainly comprises support, the shell fragment pin that is connected with support, the connecting portion that the voice coil loudspeaker voice coil that has voice coil line, described shell fragment pin comprise stiff end, extend from stiff end one end, certainly this connecting portion one end bending extension the contact site towards stiff end, the welding disk that is used to weld voice coil line that extends from the stiff end other end, be arranged on hook end on the contact site, from the vertically extending first buckle end of stiff end; Described support is provided with the hook position that is used for butt hook end and is used to cooperate the draw-in groove of this first buckle end, described first buckle end and described draw-in groove interference fit.

Preferably, described shell fragment pin also comprises from the vertically extending second buckle end that is provided with madial wall of stiff end, described support is provided with and is used for the screens that is provided with lateral wall that cooperates with this second buckle end, the lateral wall interference fit of the lateral wall butt of the madial wall of the described second buckle end and screens and the madial wall of the second buckle end and screens.

Preferably, described hook position is provided with the groove that is used to place contact site, is provided with step in these groove both sides, and the hook end is connected to this step.

Preferably, the described first buckle end is provided with groove.

Preferably, described shell fragment pin directly is connected by welding disk with inner voice coil line.

The beneficial effects of the utility model are: because plastic stent and contact terminal shell fragment pin are separately made part, be connected with the buckle end with hook end and draw-in groove screens by the hook position between the two, the welding disk of voice coil line direct spot welding on the shell fragment pin, increased in conjunction with fastness, reduced the die molding process operation.
