The description only actually at least one exemplary embodiment is illustrative below, never as to this practicality New and its application or any limitation used.

It may be not discussed in detail for technology and equipment known to person of ordinary skill in the relevant, but in appropriate situation Under, the technology and equipment should be considered as a part for specification.

In shown here and discussion all examples, any occurrence should be construed as merely exemplary, without It is as limitation.Therefore, other examples of exemplary embodiment can have different values.

It should be noted that：Similar label and letter represents similar terms in following accompanying drawing, therefore, once a certain Xiang Yi It is defined, then it need not be further discussed in subsequent accompanying drawing in individual accompanying drawing.

According to the utility model embodiment, there is provided a kind of electro-acoustic conversion device.For example, electro-acoustic conversion device can be but It is not limited to loudspeaker, receiver or microphone.Optionally, loudspeaker, receiver or microphone are moving-coil type device Or moving-iron type device.

The coil 15 for producing electromagnetic field is provided with housing, be provided with housing wrapping post 18 with for connecting The electrical connector 19 of peripheral circuits, the lead 20 of coil 15 is around being located on wrapping post 18, the exit of lead 20 and the electricity Connector 19 is electrically connected with.Electrical connector 19 is electrically connected with external circuit simultaneously, so just completes current signal by outside Transmission from circuit to coil 15.

The electro-acoustic conversion device that the utility model embodiment is provided, lead 20 by coil 15 draw after first around being located at coiling On post 18, it is connected on electrical connector 19.It is exposed outside that the setting of wrapping post 18 avoids lead 20, and reduction is even avoided Lead 20 is by exterior object hook, the risk hung.Improve the service life of electro-acoustic conversion device.

In addition, this way provides spare lead wire 20, the part lead 20 of winding can be torn open when lead 20 is too short Out use.

Fig. 1 is the exploded view of the electro-acoustic conversion device according to the utility model embodiment.The device is moving-coil type device.Example Such as, coil-moving speaker.The coil-moving speaker includes housing, vibrational system and magnetic circuit system.It is provided with the housing Cavity.For example, housing includes the fore shell 17 and rear shell 11 snapped together, the two snaps together to surround chamber inside them Body.This structure is easy to the installation of housing.Fore shell 17 has acoustic aperture.For example, the acoustic aperture can be loudspeaker or receiver The sound for going out acoustic aperture or microphone enters hole.The magnetic circuit system and the vibrational system are arranged in the cavity.

Magnetic circuit system includes T iron 12, annular magnet 13 and washer 14.Annular magnet 13 is set on the pole piece of T iron 12, China Department 14 is arranged on annular magnet 13.There is gap in annular magnet 13, washer 14, constitute magnetic between the pole piece of T iron 12 Gap.Vibrational system includes vibrating diaphragm 16 and coil 15, and the two is fixed together.Vibrational system is fixed together with fore shell 17.Shake Dynamic system is suspended above magnetic circuit system, in one end insertion magnetic gap of coil 15.

During energization, coil 15 produces electromagnetic field, the electromagnetic field and the magnetic field interaction of magnetic circuit system formation, makes coil 15 Vibration, coil 15 drives vibrating diaphragm 16 to vibrate.Vibrating diaphragm 16 is relative with acoustic aperture.

In another example, magnetic circuit system uses U iron (not shown).Magnet is cylindricality.Magnet is arranged in U iron, Washer is additionally provided with magnet.Magnetic gap is formed between the side wall and magnet, washer of U iron.Between vibrational system coil insertion magnetic In gap.The operation principle of the device is identical with above-mentioned T swages structure.

In another example, electro-acoustic conversion device is moving iron type loud-speaker.In this example embodiment, coil 15 is fixed. Moving iron type loud-speaker is the conventional structure of this area, is not elaborated herein.

Fig. 2 is the structural representation of the electro-acoustic conversion device according to the utility model embodiment.In this example embodiment, wrapping post 18 are arranged on the sidepiece of fore shell 17.The line outlet 21 for the outlet of lead 20 is additionally provided with fore shell 17.Wrapping post 18 with Electrical connector 19 is adjacent.Lead 20 is drawn by line outlet 21, winding is first carried out on wrapping post 18, then the exit of lead 20 Linked together with electrical connector 19.

In one example, electrical connector 19 is shell fragment, and exit welds together with shell fragment.For example, being welded by soldering The mode connect welds together the two, and this mode can make electric connection more stable.

Exit and shell fragment are linked together for example, it is also possible to the mode such as be connected by screw bolts, crimp.

In one example, as shown in figure 3, the wrapping post 18 is perpendicular to the outer surface of the housing.This mode is just In coiling.During coiling, the wire turn of the formation of lead 20 is arranged side by side along wrapping post 18.Rows of wire turn is moved closer in housing There is exposed possibility in portion, only outmost wire turn.By this winding, the wind that lead 20 is hooked, hung is further reduced Danger.

In one example, wrapping post 18 is embedded in the shell wall of housing.Wrapping post 18 is non-bulging in shell wall, by this The mode of kind so that the neat appearance of housing.Housing is not easy to interference with exterior object.

Fig. 5 is the side view of the wrapping post 18 according to the utility model embodiment.In this example embodiment, wrapping post 18 has line Groove 22.Also, the outer one end of wrapping post 18 is formd blocks to cored wire.During coiling, the winding of lead 20 in wire casing 22, this Planting structure can further prevent that lead 20 is exposed, serves good protecting effect.

The quantity of wrapping post 18 can be configured according to actual needs.In one example, as shown in figure 4, lead 20 For two.Wrapping post 18 is 2, and wrapping post 18 is corresponded with lead 20.Also, 2 wrapping posts 18 are symmetrically It is arranged in around the housing.This setup make it that the structure of shell is more balanced, is easy to be connected with other electronic components.

Preferably, wrapping post 18 is integrally formed with fore shell 17.For example, the material of fore shell 17 is plastics or rubber.Adopt With the method for injection molding by wrapping post 18 and housing integrated injection molding.In this way, fore shell 17 and coiling are improved The bonding strength of post 18, and simplify manufacturing procedure.

According to embodiment of the present utility model, there is provided a kind of electronic equipment.The electronic equipment is carried including the utility model The electro-acoustic conversion device of confession.

The electronic equipment has the characteristics of service life is long.

Although some specific embodiments of the present utility model are described in detail by example, this area It is to be understood by the skilled artisans that above example is merely to illustrate, rather than in order to limit scope of the present utility model.This Field it is to be understood by the skilled artisans that can be in the case where not departing from scope and spirit of the present utility model, to above example Modify.Scope of the present utility model is defined by the following claims.
