Embodiment 1

[0057] Such as Figure 1 to Figure 11 As shown, the embodiment of the present application provides a vibration assembly 100, which is applied to a speaker 200. The speaker 200 has a support body 201 and a magnetic circuit system 202 arranged on the support body 201. The vibration assembly 100 includes a diaphragm 10, a high The high-frequency canceling part 20, the high-frequency diaphragm 30 and the sound cap 40.

[0058] The diaphragm 10 is arranged on the support body 201 of the speaker 200. The diaphragm 10 is configured to vibrate relative to the magnetic circuit system 202 of the speaker 200 through the voice coil 50 to emit sound. The diaphragm 10 is configured to emit low frequency sound. The diaphragm 10 is also called a sound cone or a paper cone. The diaphragm 10 can be a diaphragm of any structure or material in the prior art, such as a paper cone diaphragm, a plastic diaphragm, a metal diaphragm, or a synthetic fiber diaphragm. any of these, but not limited to. ...

Embodiment 2

[0084] The difference between embodiment 2 and embodiment 1 is:

[0085] Such as Figure 12 to Figure 18 As shown, the high frequency canceling part 20 has a cylindrical shape, and the two ends of the high frequency canceling part 20 are open and the inside is hollow. One opening end of the high frequency canceling part 20 is connected to the inner wall of the diaphragm 10 , and the other opening end of the high frequency canceling part 20 is connected to the high frequency diaphragm 30 . Compared with Embodiment 1, the high-frequency canceling part 20 removes the connecting part, which simplifies the structure.

[0086] It should be noted that the high-frequency canceling part 20 is cylindrical, and is not limited to a cylindrical shape with the same outer diameter. Its outer diameter can gradually become smaller from the diaphragm 10 toward the high-frequency diaphragm 30, and its outer diameter can be determined by the diaphragm 10. 10 gradually becomes larger toward the ...

Embodiment 3

[0093] The difference between embodiment 3 and embodiment 1 is:

[0094] Such as Figure 19 and Figure 20 As shown, one end of the high-frequency diaphragm 30 is directly connected to the inner wall of the diaphragm 10, so that the part of the high-frequency diaphragm 30 close to the diaphragm 10 replaces the high-frequency canceling part 20, that is, the part of the high-frequency diaphragm 30 close to the diaphragm 10 is used as High frequency canceling part 20. The junction of the high-frequency diaphragm 30 and the inner wall of the diaphragm 10 is located between the larger end of the diaphragm 10 and the smaller end of the diaphragm 10 .

[0095] By adopting the above settings, the structure is effectively simplified, and the technical effect in Embodiment 1 can also be achieved.

Abstract

The invention discloses a vibration assembly, a loudspeaker and a sound device, and belongs to the technical field of loudspeakers. The vibration assembly is applied to the loudspeaker, and the loudspeaker is provided with a support body and a magnetic circuit system arranged on the support body. The vibration assembly comprises: a voice coil; a vibrating diaphragm, wherein one end of the vibrating diaphragm is connected with the voice coil, and the vibrating diaphragm is used for being arranged on a supporting body of the loudspeaker and configured to vibrate relative to a magnetic circuit system of the loudspeaker through the voice coil; a high-frequency elimination part which is arranged on the inner wall of the vibrating diaphragm; a high-frequency vibrating diaphragm which is arrangedon the high-frequency elimination part, wherein the high-frequency vibrating diaphragm protrudes towards one side far away from the vibrating diaphragm and is in a flaring shape; and a sound cap which covers the inner wall of the high-frequency vibrating diaphragm, wherein a distance is formed between the joint of the sound cap and the high-frequency vibrating diaphragm and the edge of the high-frequency vibrating diaphragm. According to the vibration assembly disclosed by the invention, the high-frequency sound, the intermediate-frequency sound and the low-frequency sound can be truly and effectively distinguished, so that the high pitch, the intermediate pitch and the low pitch can be clearly and definitely presented, the tone quality and the sound effect are effectively improved, and the authenticity of the sound is enhanced.

Description

technical field [0001] The invention relates to the technical field of speakers, in particular to a vibrating component, a speaker and an audio device. Background technique [0002] A horn (also known as a loudspeaker) is a conversion device that converts electrical energy into sound. When different electronic energies are transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the diaphragm to vibrate, because the electronic energy Change at any time, the coil of the speaker will move forward or backward, so the diaphragm of the speaker will move accordingly, this action changes the density of the air and produces sound. [0003] The horn usually includes a pot frame, a vibration system and a magnetic circuit system. Vibration systems usually include rings, diaphragms (also known as sound cones or paper cones), voice coils, elastic waves, etc. Internal magnetic magnetic circuit systems usually incl...
