The utility model provides an electro-acoustic transducer, comprising a main body of the electro-acoustic transducer. Electric terminals are arranged on the main body of the electro-acoustic transducer and the electric terminals are connected with a flexible circuit board implementing electric conduction. An elastic element is arranged on the main body of the electro-acoustic transducer for positioning the said flexible circuit board. Comparing with the present technology, the elastic element of the utility model accurately locates the FPC, eclectically conducts with the electric terminals on the main body of the electro-acoustic transducer, and can prevent the problem of departure from the specific location after assembling products.
Description
Technical field
The utility model relates to a kind of electroacoustic transducer, relates in particular to a kind of FPC interconnection system electroacoustic transducer.
Background technology
Electroacoustic transducer is widely used in portable electronic equipments such as mobile phone, notebook computer.Along with fast development, the people of these portable electronic equipments are more and more stronger to its functional requirement, the also corresponding development apace of the electroacoustic transducer that is applied thereon.
Electroacoustic transducer is finished electric energy as microphone devices such as loud speaker, receivers and is converted acoustic energy in order to finish the conversion between electric energy and the acoustic energy, and microphone is finished acoustic energy and converted electric energy to.For realizing the conversion between electric energy and the acoustic energy, electroacoustic transducer all needs to link to each other with external circuit, and the connected mode that its circuit inputs or outputs generally includes several: 1, contact pin type, promptly realize that by two metal ferrules circuit inputs or outputs; 2, lead type promptly realizes that by two leads circuit inputs or outputs; 3, add the connection shell type, promptly suit one adapter sleeve on electroacoustic transducer is provided with spring to realize that circuit inputs or outputs in adapter sleeve; 4, FPC (Flexible Printed Circuit flexible printed circuit board) interconnection system promptly links to each other to realize that circuit inputs or outputs with the power connection end on the electroacoustic transducer is sub by FPC.As shown in Figure 1, on power connection end of electroacoustic transducer 10, be welded with one and realize the FPC 12 that circuit inputs or outputs by scolder 11.
About the FPC interconnection system, only the location measure that does not have other by welding is positioned FPC on the electroacoustic transducer, can not reach desirable effect, but can exist FPC location inaccurate and the problem of assigned address after the product assembling, occurs departing from, thereby the instability that electrically conducts that can cause power connection end and FPC influences the performance of this electroacoustic transducer.
Thereby, be necessary to study a kind of FPC interconnection system electroacoustic transducer that can accurately locate, electrically conduct good.
The utility model content
The technical problem that the utility model need solve is to overcome above-mentioned deficiency, and a kind of well behaved FPC interconnection system electroacoustic transducer is provided.
According to the above-mentioned technical problem that needs solution, designed a kind of electroacoustic transducer, comprise the electroacoustic transducer body, on the electroacoustic transducer body, be provided with power connection end, described power connection end links to each other with realizing the flexible PCB that electrically conducts, and also is provided with the flexible member that is attached thereto and realizes to locate described flexible PCB on the electroacoustic transducer body.
As the utility model one step improvement, the groove of described flexible PCB is held in described flexible member and electroacoustic transducer body formation one.
Further improve as the utility model, described flexible member is a flat board, and this flat board is provided with and resists the elastic press that flexible PCB links to each other with power connection end.
Compared with prior art, the flexible member that the utility model is provided with makes FPC accurately locate, electrically conduct well with power connection end on the electroacoustic transducer body, also can not occur departing from the problem of assigned address after product assembling.Thereby, the utlity model has well behaved advantage.

Embodiment
The utility model is described in further detail below in conjunction with drawings and embodiments.
As Fig. 2, Fig. 3, shown in Figure 4, be the utility model embodiment, a kind of FPC interconnection system electroacoustic transducer, this electroacoustic transducer is a kind ofly to convert audio electrical signal the electroacoustic transducer of acoustical signal to, and it comprises electroacoustic transducer body 2, diving board 3, FPC (Flexible Printed Circuit flexible printed circuit board) 4.
As shown in Figure 5, this electroacoustic transducer body 2 comprises basin frame 21, is contained in magnetic bowl 22 in the basin frame 21, is placed in permanent magnet 23 in the magnetic bowl 22, is arranged at voice coil loudspeaker voice coil 24, the vibrating diaphragm 25 that is connected with voice coil loudspeaker voice coil 24 in permanent magnet 23 and the magnetic gap that magnetic bowl 22 forms, covers and be connected to the loam cake 26 on the basin frame 21 and be located at power connection end 27 on the basin frame 21.Voice coil loudspeaker voice coil 24 is by power connection end 27 input electrical signals.
Diving board 3 is a flat board, and the one side is provided with two elastic press 31.This diving board 3 links to each other with four ends of electroacoustic transducer basin frame 21, also forms a groove 32 between the two.
As shown in Figure 6, FPC 4 is provided with the contact pins 41 that realization electrically conducts.This FPC 4 is placed in the groove 32 between diving board 3 and the basin frame 21 realizing accurate location, and also can not occur departing from the situation of assigned address after the product assembling; Elastic press 31 on the diving board 3 resists FPC 4, contact pins 41 on the FPC 4 is linked to each other with power connection end 27 electrically conduct well with realization.
When the utility model embodiment F PC interconnection system electroacoustic transducer is applied on the outer carrier, FPC 4 links to each other with circuit on the carrier to realize input electrical signal, and voice coil loudspeaker voice coil 24 is subjected to the motive force of alternation in magnetic gap, produces alternate motion, drive vibrating diaphragm 25 vibrations, thereby sound.
The utility model embodiment is a kind of electroacoustic transducer that converts electrical energy into sound acoustic energy, and it can also be the electroacoustic transducer of other employings such as microphone, loud speaker, news Chinese percussion instrument FPC interconnection 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 creation design; can also make improvement, but these all belong to protection range of the present utility model.
