Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

As shown in fig. 1 and 2, the utility model discloses loudspeaker feeler structure, loudspeaker body 1 includes basin frame 2, locates loudspeaker PCBA board 4 on 2 terminal surfaces of basin frame, be equipped with the positive negative pole contact that is used for being connected with the positive negative pole pin electricity of loudspeaker body 1's coil on the loudspeaker PCBA board 4, be equipped with respectively on the positive negative pole contact and have elastic positive negative pole shell fragment 3, positive negative pole shell fragment 3 is connected with the positive negative pole lead wire and the positive negative pole contact electricity of loudspeaker body 1's coil to make the positive negative pole lead wire and the positive negative pole shell fragment 3 of coil switch on.

As shown in fig. 3, the speaker body 1 further includes a vibrating diaphragm 8, the coil is fixed on the vibrating diaphragm 8, and the vibrating diaphragm 8 is disposed on a surface of the basin stand 2 opposite to the positive and negative elastic pieces 3; two positive and negative elastic pieces 3 are arranged.

The utility model discloses in, loudspeaker PCBA board 4's structure is the same with the structure that is used for loudspeaker PCBA board among the prior art, and the difference is only with loudspeaker PCBA board 4 in the prior art on be used for become the shell fragment by the wire with the PCBA board connected mode of product.

As shown in fig. 2, two insulating bumps 7 are disposed on the surface of the end of the speaker PCBA board 4 on which the positive and negative elastic pieces 3 are disposed, the insulating bumps facing the positive and negative elastic pieces 3, so as to prevent the positive and negative elastic pieces 3 from contacting the frame 2 after the positive and negative elastic pieces 3 are pressed to generate resonance.

As shown in fig. 2, the positive and negative elastic pieces 3 include a fixed section 31, an extending section 32, and a contact section 33, which are sequentially arranged, and the fixed section 31 is welded with the positive and negative leads of the coil and the positive and negative contacts of the horn PCBA board 4, so as to fix the positive and negative elastic pieces 3 on the horn PCBA board 4.

As shown in fig. 2, the contact section 33 is an arc shape tilted toward the frame 2 to increase the contact surface.
