Description

Speaker module with conducting characteristic

Technical Field

The utility model relates to the technical field of speakers, in particular to a speaker module with a conducting characteristic.

Background

The loudspeaker is an indispensable component part of electronic products, and people continuously improve the sound quality requirements and need to upgrade the prior art, so the market pushes back-to-back loudspeakers. The back-to-back loudspeaker has the advantages of large loudness and good vibration reduction effect, and is widely applied.

But the back-to-back speaker has four outlets and is sandwiched between the snaps. If wires or FPCs are led out before the speaker is mounted back-to-back, the lengthy wires are detrimental to the circulation and reliability of the parts. There is therefore a need for a new design that addresses the problem of back-to-back speaker extraction.

Disclosure of Invention

The utility model aims to solve the technical problems that: in order to overcome the defects in the prior art, the loudspeaker module with the conduction characteristic is provided.

The technical scheme adopted for solving the technical problems is as follows: the utility model provides a speaker module of switch-on characteristic, includes back-to-back place in speaker A and speaker B of same sound intracavity, speaker A and speaker B all have the link that protrudes in speaker module basin frame, one the link be connected with two leading-out ends through a leading-out piece, the link is spacing through being fixed in the protruding piece outside the basin frame.

Further, the connection ends of the loudspeaker A and the loudspeaker B are respectively a bonding pad A and a bonding pad B, and the bonding pad A and the bonding pad B are mutually welded or not welded.

The four leading-out ends are changed into two bonding pads welded with each other through two-by-two self connection, so that the number of leading-out wires is reduced, the four wires are changed into two wires, and materials and labor are reduced.

Of course, for products with special requirements, the two bonding pads can be led out without welding the four wires, and the speaker A/B is controlled separately.

Further, the protruding part is a plastic part, and at most one connecting end is injection molded in the plastic part.

Specifically, the plastic part is fixed outside the basin frame of the loudspeaker B, the bonding pad B is injection molded in the plastic part, and the bonding pad A is placed on the plastic part or is connected with the plastic part in an inserting mode.

Furthermore, the lead-out piece adopts an FPC board or a soldering lug which is injection molded in a speaker module basin frame.

Further, the sound production directions of the loudspeaker A and the loudspeaker B are opposite.

The beneficial effects of the utility model are as follows: the loudspeaker module is simple in structure, protrudes out of the bonding pad position of the inner core, is used for guiding out the clamping wire for the bonding wire of the conventional product, and does not occupy more space than the conventional product;

the structure assembly process is simple and convenient, the performance of the product is not affected, and the loudspeaker module can be assembled on one side panel of the sound cavity and then welded, so that the rotation of the strip line is avoided, the reliability is high, and the cost is low;

the four leading-out ends are changed into two bonding pads welded with each other through two-by-two self-connection, so that the number of leading-out wires is reduced, and the four wires are changed into two wires, so that materials and labor are reduced; for products with special requirements, the two bonding pads can be led out without mutual welding by welding four wires, and the loudspeaker A/B is controlled separately.
