Problems solved by technology

[0003] However, the existing earphones focus on appearance design and manufacturing cost, while ignoring the wearing comfort of earphones. The pursuit of earphones is the perfect playback of sound effects. The vibration brought by the sound for a long time will damage the ears, because the human ear is very sensitive. The earphone cavity vibrates with the frequency of the music, and the user's ear has real resonance vibration. Long-term vibration It can cause ear itching and numbness; especially for audio pronunciation with strong rhythm and obvious bass effect, it will affect the user's normal hearing due to vibration
[0004] Furthermore, with the vibration of the earphone cavity, the earphone will produce sound leakage, which cannot provide the wearer with an auditory feast of surround sound effect.

Abstract

The invention discloses a micro speaker with an acoustic damping function, comprising a bracket and a protecting cover which are mutually engaged, wherein the bracket and the cover are fastened to form a receiving cavity, and a magnet, a spring washer and a sound film are sequentially arranged in the receiving cavity; a U cup and a tuning paper are arranged inside the bracket, and a tuning hole isprovided in the middle of the bottom of the U cup; a damping ring is sleeved outside the protecting cover; the magnet is circular and arranged inside the bracket, the spring washer is arranged on theupper surface of the magnet, and the magnet is inserted into an arc opening of the sound film. The invention aims to provide a damping structure of a micro speaker, which effectively reduces the vibration transmission in the interior of the micro speaker, thereby ensuring comfortable wearing of the user and uniform sound effect, reducing distortion, and restoring true sound reproduction.

Description

technical field [0001] The invention relates to the technical field of electroacoustics, in particular to a miniature loudspeaker with an acoustic damping function. Background technique [0002] With the popularity of MP3 and video players, and the widespread use of new smart phones, people are increasingly inseparable from earphones when listening to music and watching videos. At the same time, earphones, as an essential accessory product for MP3, video players, mobile phones, tablet computers, etc., have also developed rapidly. And at the same time have decorative and functional headphones. [0003] However, the existing earphones focus on appearance design and manufacturing cost, while ignoring the wearing comfort of earphones. The pursuit of earphones is the perfect playback of sound effects. The vibration brought by the sound for a long time will damage the ears, because the human ear is very sensitive. The earphone cavity vibrates with the frequency of the music, and...
