Abstract

The present utility model relates to a miniature speaker, comprising a miniature speaker body; said miniature speaker body has at least one pair of leads that lead out from the interior of the miniature speaker and extend outward; the miniature speaker body also comprises an outer cover; a splitting guide groove is arranged at a position relative to said outer cover and said leads; the leads pass through the splitting guide groove. The design of the miniature speaker of the present utility model has an added splitting guide groove, improving the reliability of the miniature speaker; the invention has the features of fall prevention and pressure resistance, and it is easy for an operator to perform line-splitting operations.

Description

a miniature speaker

Technical field

The utility model relates to a loudspeaker, in particular to a microspeaker.

Background technique

A speaker is a transducer used to convert an electrical signal into an audio signal. Micro-speakers are one type of speakers. Miniaturization is one of the mainstream trends in the development of today's loudspeakers. Small, lightweight micro-speakers provide consumers with high-quality listening enjoyment. The micro-speakers mainly include a basin frame (bracket), a magnetic steel (magnet), a pole piece (was), a sound film, a voice coil, a front cover, a wiring board (circuit board), and a damping cloth (tuning paper).

However, most of the current micro-speakers have a pair of leads extending from the inside. The voice coils of the micro-speakers are very thin and fragile, and slight pressure or impact can cause disconnection. This is a fatal problem of the micro-speakers. Reliability, drop resistance and pressure resistance are not perfect.

Utility model content

The technical problem to be solved by the utility model is to provide a micro-speaker that protects the lead wire and at the same time facilitates the split line.

The technical solution proposed by the present invention to solve the above technical problem is: a micro-speaker comprising a micro-speaker body, the micro-speaker body having at least one pair of leads extending from the inside thereof and extending to the outside, the micro-speaker body further The cover case includes a branch guide groove at a position opposite to the lead position of the cover case, and the lead wire passes through the branch line guide groove.

Further, the branch guiding groove is arranged along a height direction of the outer casing, and a top end outlet of the branch guiding groove is located at a top surface of the back of the micro-speaker body.

Further, the outer casing includes a bottom skirt portion and a top cover portion, and a slope engaging portion is disposed between the bottom skirt portion and the top cover portion, and the branching guide groove passes through the slope engaging portion.

The beneficial effects of the utility model are:

The micro-speaker of the utility model is designed with a branch guiding groove, which can make the micro-speaker more reliable, has the characteristics of anti-drop and anti-pressure, and is easy for the operator to perform the branching operation. Increase the split guide groove, which can be well separated and protected, avoiding the risk of the lead being squeezed and impacted by the outside.

DRAWINGS

The microspeaker of the present invention will be further described below with reference to the accompanying drawings.

2 is a schematic structural view of a bottom view of a microspeaker in the present invention.

Detailed ways

Example

According to FIG. 1 and FIG. 2, the microspeaker of the present invention includes a microspeaker body having at least one pair of leads 1 extending from the inside thereof and extending to the outside, the microspeaker body further including The outer casing 2 is provided with a branching guide groove 3 at a position opposite to the position of the lead casing 2, and the lead wire 1 passes through the branching guide groove 3.

It may be preferable that the branch guide groove is arranged along the height direction of the outer casing 2, and the top end outlet of the branch guide groove 3 is located at the top surface of the back of the micro-speaker body.

It is further preferred that the outer casing 2 includes a bottom skirt portion 2-1 and a top cover portion 2-2, and a slope is provided between the bottom skirt portion 2-1 and the top cover portion 2-2. The connecting portion 2-3 passes through the slope guiding portion 2-3.

The present invention is not limited to the above embodiments, and the technical solutions of the above various embodiments of the present invention can be cross-combined with each other to form a new technical solution, and the technical solutions formed by the equivalent replacement are all required by the present invention. Within the scope of protection.
