Abstract

The invention relates to the technical field of headset, and discloses a passive radiation type micro speaker comprising a speaker frame and a loudspeaking component coaxially arranged in the speaker frame. A first through hole penetrating inside and outside of the speaker frame is formed in the center of the bottom of the speaker frame, a second through hole is formed in a position, opposite to the first through hole, on the loudspeaking component, and the first through hole is provided with a passive radiation frame opposite to the second through hole; a damping fin is arranged on the upper ring of the outer end face of the bottom side of the speaker frame. The invention further discloses a headset comprising the passive radiation type micro speaker. The passive radiation type micro speaker has the advantages that since the first through hole penetrating the inside and outside of the speaker frame is formed in the center of the bottom of the speaker frame, the second through hole is formed in the position, opposite to the first through hole, on the loudspeaking component, the first through hole is provided with the passive radiation frame opposite to the second through hole, and the damping fin is arranged on the outer end face of the bottom side of the speaker frame, the passive radiation frame and the damping fin are utilized to produce proper acoustic impedance, low-frequency sound quality is improved, and distortion is reduced.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to a passive radiation micro-speaker and earphones. Background technique [0002] With the continuous improvement of material living standards, listening to music has become a way for people to relieve their mood and reduce stress in their spare time. At the same time, with people's continuous pursuit of high-quality life, people also have higher requirements for the quality of earphones. The manufacturer starts from the combination of humanistic care and health concepts, in order to allow every user to listen to the pure sound of life, and develops speakers with ultra-low frequency and deep dive to meet the needs of earphone consumers. For the earphones currently on the market, the speaker units are all of ordinary design, and the space and volume requirements of the inner cavity of the earphone have certain limitations, and it is not easy to meet the consumer's demand for low-f...
