Problems solved by technology

[0002] The voice coil of the traditional loudspeaker will have a broken voice coil during the long-term vibration process, which will cause the above problems. Because the broken line of the voice coil will interfere with the frame during the vibration process, the stress will be in the voice coil. Stress concentration occurs at the broken line, and the stress concentration will shorten the service life of the lead wire of the voice coil and cause the problem of breakage

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] figure 1 There is no relief part in the second step surface of the frame structure in the prior art. During the vibration process of the voice coil, the broken line part of the voice coil will interfere with the second step surface of the frame structure, so that the vibration stress All will be concentrated in the broken line of the voice coil, so the broken line of the voice coil is prone to breakage.

[0018] Such as Figure 2 to Figure 4 The frame structure of the micro-speaker shown includes a frame body 1, which is characterized in that: the end face of the frame body 1 is a first step surface 5, and the inner side of the frame body 1 is sunken to form a second step surface 3, corresponding to A relief portion 2 lower than the second stepped surface 3 is formed on the second stepped surface 3 of the voice coil folded line portion 71 , and the position of...

Abstract

The invention belongs to a loudspeaker assembly and particularly relates to a basin stand structure of a micro loudspeaker. The structure comprises a basin stand body and is characterized in that the end face of the basin stand body is a first step face, the inner side of the basin stand body is concave to form a second step face, and a receding portion lower than the second step face is formed on the position, corresponding to a voice coil line folding portion, of the second step face. The basin stand structure of the loudspeaker is improved, the situation that stress accumulates on the line folding portion of a voice coil in the vibration process of the voice coil is avoided, and the problem that the voice coil line folding portion is easy to break is solved.

Description

technical field [0001] The invention belongs to loudspeaker components, in particular to a basin frame of a miniature loudspeaker. Background technique [0002] The voice coil of the traditional loudspeaker will have a broken voice coil during the long-term vibration process, which will cause the above problems. Because the broken line of the voice coil will interfere with the frame during the vibration process, the stress will be in the voice coil. Stress concentration occurs at the broken line, and the stress concentration will shorten the service life of the lead wire of the voice coil, which is prone to breakage. Contents of the invention [0003] The present invention aims at the deficiencies of the prior art, improves the frame structure of the loudspeaker, avoids the accumulation of stress on the broken line of the voice coil during the vibration process, and thus overcomes the problem that the broken line of the voice coil is prone to breakage question. [0004] ...
