Description

Technical Field

[0001] The present application relates to the technical field of audio equipment, and more specifically, to an audio equipment and an audio device. Background Art

[0002] An audio device is a device that converts electrical signals into acoustic signals for the purpose of sound dissemination. An audio device generally includes a speaker assembly and a shell for assembling the speaker assembly. The speaker assembly generally includes a magnetic circuit, a voice coil, a bracket, a basin, a spring and a radiator. The radiator includes a folding ring and a diaphragm. The electromagnetic effect of the magnetic parts and the voice coil causes the diaphragm in the radiator to vibrate, thereby resonating with the surrounding air and emitting sound to the outside.

[0003] However, in the process of the audio equipment generating sound, since the sound source is the speaker assembly, and the speaker assembly is assembled in the shell, a cavity is formed inside the shell. During the process of the speaker assembly generating vibration, sound waves are also generated inside the shell. The sound waves will propagate inside the shell, thereby forming standing waves inside the shell. When standing waves exist, the vibration of the speaker assembly will be affected, and the sound emitted by the speaker assembly will be distorted, which is not conducive to the use of the audio equipment.
