Abstract
The utility model relates to the field of electroacoustic energy sound production, in particular to a miniature acoustic generator integrated system. At least part of a PCB embedded in a shell for containing and supporting a miniature acoustic generator body is overlapped with the acoustic generator body, and at least part of the PCB at the overlapped part is tightly pressed in the shell by the acoustic generator body so as to ensure that the PCB can bear larger pressure and can not fall out of the shell when a conductive terminal connected with the PCB receives pressure from outside, thus improving the overall performance of the acoustic generator integrated system.
Description
[technical field]
The utility model relates to electroacoustic energy sounding field, specifically refers to a kind of integrated system of minitype acoustic generator.
[background technology]
The minitype acoustic generator integrated system is widely used on the portable electronic equipments such as mobile phone, notebook computer.Along with fast development, the people of these portable electronic equipments are more and more higher to its stable performance requirement, the also corresponding development apace of the minitype acoustic generator integrated system that is applied thereon.
Relevant existing minitype acoustic generator integrated system comprises a plastic casing and is contained in the interior minitype acoustic generator body of housing.Described minitype acoustic generator body comprises the magnetic bowl that is placed in the basin frame, be contained in permanent magnet in the magnetic bowl, be arranged at the voice coil loudspeaker voice coil in the magnetic gap that permanent magnet and magnetic bowl-type become, the vibrating diaphragm that links to each other with voice coil loudspeaker voice coil, and the inlet wire of voice coil loudspeaker voice coil and outlet are welded on the interior pcb board of housing.Usually play glue to be fixed in the housing at the pcb board periphery, the position of relative pcb board is provided with the installing hole that is embedded conducting terminal on the base of described housing, and conducting terminal can be a spring.One end of spring is conflicted and is electrically connected with it on pcb board.Yet, when being subjected to external force extruding pcb board at spring, only rely on play glue mode fixedly pcb board have risk, when pcb board is subjected to the excessive external force housing that will come off, this performance to the integrated system of minitype acoustic generator causes very big influence.
[utility model content]
The purpose of this utility model is to solve the interior pcb board of acoustical generator integrated system and locatees unstable problem, and a kind of minitype acoustic generator integrated system of stable performance is provided.
According to the above-mentioned technical problem that needs solution, a kind of minitype acoustic generator integrated system is provided, comprise the shell of accommodating and support the minitype acoustic generator body, be embedded acoustical generator body, pcb board in the shell, the voice coil loudspeaker voice coil lead of acoustical generator body is electrically connected pcb board, wherein pcb board is overlapping to small part and acoustical generator body, has at least a part of pcb board to be compressed in the enclosure so that pcb board is fixedly positioning by the acoustical generator body in the overlapping part.
Preferably, described pcb board is not coated with glue so that pcb board fixedly positioning in the enclosure with the overlapping part periphery of acoustical generator body.
The position of relative pcb board is provided with the installing hole that is embedded conducting terminal on the described shell.
Described conducting terminal comprises the spring or the metal pin of conductivity.
Compared with prior art, it is overlapping to small part and acoustical generator body that the pcb board that is embedded in the shell of minitype acoustic generator body is accommodated and supported to the utility model minitype acoustic generator integrated system, overlapping part has at least a part of pcb board to be pressed on inner surface of outer cover by the acoustical generator body, to guarantee when the conducting terminal that is connected with pcb board is under pressure in the external world, pcb board can bear bigger pressure, can not come off, improve the overall performance of acoustical generator integrated system from inner surface of outer cover.
[description of drawings]
Fig. 1 is the schematic perspective view of the utility model minitype acoustic generator integrated system;
Fig. 2 is the decomposing schematic representation of the utility model minitype acoustic generator integrated system;
Fig. 3 is an A-A generalized section among Fig. 2.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 1, the utility model minitype acoustic generator integrated system comprises in the plastic casing 100 be made up of base and lid, the shell accommodates and supports minitype acoustic generator body 200, and minitype acoustic generator body 200 is often referred to the Microspeaker monomer.After opening lid, the minitype acoustic generator integrated system is illustrated in figure 2 as the utility model one preferred embodiment, also be embedded pcb board 300 in the shell 100, the part of pcb board 300 and acoustical generator body 200 are overlapping, and some pcb board is pressed on shell 100 inner surfaces by an end of acoustical generator body 200 in the overlapping part, in order to fixedly positioning pcb board 300 more, be not coated with glue by the part periphery that acoustical generator body 200 covers at pcb board 300.
As shown in Figure 3, be A-A generalized section among Fig. 2.The position of relative pcb board 200 is provided with installing hole 110a, the 110b that is embedded conducting terminal (not shown), corresponding two-sided pad 310a, the 310b of being provided with on the shell 100 on pcb board 200; The end that conducting terminal is embedded its conducting terminal in installing hole 110a, 110b is electrically connected with corresponding two- sided pad 310a, 310b, usually conducting terminal is the spring or the metal pin of conductivity, after conducting terminal is subjected to ambient pressure, ambient pressure is passed to pcb board 300, because the part pcb board is subjected to reverse pressure from acoustical generator body 200, force whole pcb board 300 to be fitted in closely on shell 100 inner surfaces, thereby prevent pcb board 300 displacement even come off, help improving the reliability of whole minitype acoustic generator integrated system.
Above-described only is execution mode of the present utility model, should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model design, can also make improvement, but these all belongs to protection range of the present utility model.
