Specific embodiment

For technology contents, the objects and the effects that the utility model is described in detail, below in conjunction with embodiment and match Attached drawing is closed to be explained.

The design of the utility model most critical is: the first lead drawn on voice coil and the second lead are arranged in voice coil On symmetrical two angles.

Before this, the technical solution of the utility model in order to facilitate understanding, for English involved in the utility model Abbreviation, equipment etc. are described as follows:

(1), FPCB: it is in the present invention the abbreviation of Flexible Printed Circuit Board, means soft Property printed circuit board, it is a kind of using patterned printed circuit board made of flexible parent metal, by insulating substrate and is led Electric layer is constituted, and can have binder between insulating substrate and conductive layer.

Please refer to Fig. 1 to Fig. 5, Microspeaker, including voice coil, the voice coil include from the first lead diagonally drawn with Second lead, the outlet point of the first lead and the outlet point of second lead are separately positioned on the voice coil symmetrically On two angles.

As can be seen from the above description, the utility model has the beneficial effects that: by the outlet point of the first lead on voice coil with The outlet point of second lead is separately positioned on the voice coil on symmetrical two angles, so that two outlet points were centrosymmetric Mode, to alleviate the excessive problem of the unilateral stress of voice coil, it is ensured that the balance of monomer vibration, so that the audio of loudspeaker is more Good, whole design wide adaptability is practical, use easy to spread.

Further, the first lead extends outwardly since outlet point with second lead.

As can be seen from the above description, first lead extends outwardly since outlet point with second lead, convenient for welding.

As can be seen from the above description, the outlet point of i.e. first lead and the outlet point of the second lead are also essentially central symmetry, Further to alleviate the excessive problem of the unilateral stress of voice coil, to reach better audio.

As can be seen from the above description, the end of first lead and the second lead extends away from the direction of voice coil respectively, this It is to be fixed since voice coil is generally located on centre by the component on both sides, the end of first lead and the second lead needs to weld On the firmware on both sides, consequently facilitating welding.

Further, the voice coil is single-tone circle.

As can be seen from the above description, this programme is primarily directed to structure designed by two leads of conventional voice coil.

As can be seen from the above description, two leads are welded on different devices, this is because the outlet point of lead is symmetrical Position on, if be arranged on same device, be difficult so that connect with lead pad setting in the same side, to be unfavorable for sky Between be laid out.

As can be seen from the above description, providing the scheme that two leads of one kind are welded on different devices.

As can be seen from the above description, under the premise of meeting the welding of two leads, so that pad in frame is in the same side, into And guarantee loudspeaker in the application at complete machine end, if loudspeaker mould group will this is because pad in frame is located at not ipsilateral FPC cabling space is reserved on monomer periphery, wastes structure space.

Please refer to Fig. 1 to Fig. 5, the embodiments of the present invention one are as follows:

Microspeaker, including middle patch 1, sound film 2, voice coil 3, FPCB4, frame 5 and magnetic circuit system 6, wherein, voice coil 3 Including from the first lead 31 diagonally drawn and the second lead 32, the outlet point of first lead 31 and the outlet point of the second lead 32 It is separately positioned on voice coil 3 on symmetrical two angles.

Wherein, first lead 31 and the second lead 32 include beginning and end, the position that beginning is connect with the side of voice coil 3 For outlet point, first lead 31 and the second lead 32 respectively along voice coil 3 short side since outlet point towards with outlet point Opposite direction extends, and end extends away from the direction of voice coil 3 respectively.

Wherein, voice coil 3 is single-tone circle.

Please refer to Fig. 1 to Fig. 5, the embodiments of the present invention two are as follows:

Microspeaker, on the basis of example 1, FPCB4 include the first pad 41 and the second pad 42, the first weldering Disk 41 and the second pad 42 are connected and are located at the same side；Frame 5 include third pad 51 and the 4th pad 52, third pad 51 with 4th pad 52 is connected and is located at the same side.

Wherein, in the present embodiment, first lead 31 is welded on the first pad 41 of FPCB4, the welding of the second lead 32 On the third pad 51 of frame 5, the first pad 41 is connected with 51 circuit of third pad, and the second pad 42 and the 4th pad 52 weld It connects, so that the pad in frame 5 is in the same side.

In conclusion Microspeaker provided by the utility model, by the outlet point of the first lead on voice coil and second The outlet point of lead is separately positioned on the voice coil on symmetrical two angles, so that the side that two outlet points are centrosymmetric Formula, to alleviate the excessive problem of the unilateral stress of voice coil, it is ensured that the balance of monomer vibration, so that the audio of loudspeaker is more preferable； First lead is welded on the first pad, the second lead is welded on third pad, and the first pad and third pad pass through the The welding of two pads and the 4th pad and be connected so that the pad in frame is located at the same side, and then guarantee loudspeaker in complete machine The application at end, whole design wide adaptability is practical, use easy to spread.
