Embodiment Construction

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0023] like figure 2 and image 3 As shown, the present invention provides a preferred embodiment of a loudspeaker.

[0024] A loudspeaker, the loudspeaker comprises a sound membrane 210, a suspension edge 220 and a support portion 230, the suspension edge 220 and the support portion 230 are both annular structures, and the inner contour of the suspension edge 220 is connected with the outer contour of the sound membrane 210 , the outer contour of the suspension edge 220 is connected with the inner contour of the support portion 230 , and the width of the suspension edge 220 is not equidistant.

[0025] Specifically, the speaker is generally composed of four parts, including the high-pitched region 211 and the mid-bass region 212 that constitute the sound membrane 210 , as well as the suspension edge 220 and the support portion 230 . 211 ...

Abstract

The invention relates to the field of loudspeakers, in particular to a loudspeaker. The loudspeaker comprises a voice diaphragm, a dangling edge and a supporting part, the dangling edge and the supporting part are both of an annular structure, the inner contour of the dangling edge is connected with the outer contour of the voice diaphragm, the outer contour of the dangling edge is connected with the inner contour of the supporting part, and the width of the dangling edge is set in a non-equidistant mode. The beneficial effects of the loudspeaker are that compared with the prior art, the width of the dangling edge is arranged in a non-equidistant manner, the phenomenon that the loudspeaker generates resonance is reduced, wave crests and wave troughs generated due to resonance segmentation can be effectively inhibited, vibration transmitted to the dangling edge by the voice diaphragm is scattered, and the resonance phenomenon generated by vibration reflected back from the dangling edge is avoided.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a loudspeaker. Background technique [0002] The speaker is actually a conversion device that converts electrical energy into sound. When different electronic energy is transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the paper plate to vibrate, because the electronic energy changes at any time. The coil of the horn will move forward or backward, so the paper plate of the horn will follow the movement, which changes the density of the air and produces sound. [0003] like figure 1 As shown, the speaker includes a sound membrane 110, a suspension edge 120 and a support portion 130. The outer contour of the sound membrane 110 is a circular structure, and the suspension edge 120 and the support portion 130 are both circular structures. The outline is an elliptical structure, and the suspension edge 120 a...
