Speaker unit and speaker

Abstract

The invention provides a speaker unit and a speaker. The speaker comprises a box body, a support frame, a diaphragm, an internal dangling edge, a magnetic loop assembly, a voice coil, and a double-dangling edge structure. The upper half part of the support frame forms an opening. The diaphragm is disposed at the opening of the support frame. The internal dangling edge is connected between the periphery of the diaphragm and the periphery of the opening of the support frame. The magnetic loop assembly is arranged in the lower half part of the support frame. The voice coil is disposed at the bottom of the diaphragm, and corresponds to the magnetic loop assembly. The double-dangling edge structure is connected between the outer periphery of the support frame and the box body. Irregular displacement can be restrained to avoid distorted or unclear voice, and the best bass and low-frequency effect is achieved.

Description

Technical field [0001] The invention relates to a horn unit and a horn, in particular to a horn unit and a horn with a double suspension structure. Background technique [0002] Small speakers are widely used in the market due to their light weight, easy installation and low price. However, due to the small size and small caliber of small speakers, its inherent disadvantage is insufficient bass energy. However, if a small speaker wants to achieve a low-frequency effect, it is related to the vibration amplitude of the diaphragm of the small speaker and the speaker unit. So like figure 1 and figure 2 As shown, the speaker unit A100 of a small speaker A300 can be suspended on the cabinet A200 through the outer overhanging edge A70 to increase the vibration amplitude of the speaker unit A100 and its diaphragm A20 to obtain low frequency. effect. However, when the vibrating membrane A20 performs piston movement and generates a large vibration, the entire speaker unit A100 suspende...

AI Technical Summary

Problems solved by technology

However, when the vibrating membrane A20 performs piston movement and generates large-scale vibrations, the entire speaker unit A100 suspended on the box A200 is displaced along the axis due to the action force and reaction force, often resulting in irregular displacements, such as unexpected horizontal displacement

Due to the inability to linearly displace along the axis, the vibrating membrane A20 vibrates unevenly, resulting in sound distortion and unclear sound, which cannot be effectively avoided even with the harder outer hanging edge A70
