Problems solved by technology

However, this method will generate additional sound, causing users to hear unexpected sounds
On the other hand, semi-breathable paper will make its low-frequency impedance unable to be accurately controlled within a certain range, resulting in unsatisfactory timbre performance and poor dynamic response of low-frequency sounds

Embodiment Construction

[0033] ginseng figure 1 As shown, the present invention provides an earphone 1 with a passive sound membrane, which is worn on the user's ear 9 . The earphone 1 with passive sound film comprises a sound unit 10, a sound film assembly 20 (referring to figure 2 shown) and an elastic member 50 , the sound membrane assembly 20 is arranged at one end of the sounding unit 10 , and the elastic member 50 is arranged at one end of the sounding unit 10 close to the ear 9 of the user.

[0034] The sounding unit 10 can be driven in different driving modes such as moving coil, electrostatic and balanced armature according to factors such as cost, frequency, sensitivity requirements, sound quality and service life. The elastic member 50 is a high-density sponge earpad, a silicone earplug, or a sponge earplug. When in use, one end of the elastic member 50 is attached to the user's ear, so as to increase the airtightness and comfort of the earphone 1 with the passive sound membrane on the ...

Abstract

An earphone is worn on an ear of a user. The earphone comprises a vocal monomer and a sound film assembly. The sound film assembly comprises an assembling ring and a passive sound film. The vocal monomer is arranged at one end, close to the ear of the user, of the assembling ring. The passive sound film closes one end, far away from the ear of the user, of the assembling ring. The passive sound film, the assembling ring and the vocal monomer together form a rear cavity chamber.

Description

technical field [0001] The invention relates to an earphone, in particular to an earphone using a passive sound film to form a rear cavity of a sounding unit. Background technique [0002] Nowadays, people often wear earphones to listen to music in order not to disturb the surrounding people when listening to music, and because earphones are often carried by people, portable earphones should be small in size and light in weight. [0003] However, due to the small volume of the earphone, the volume of the sounding unit disposed in the earphone is limited, so that the size of the acoustic cavity for restoring the sound is also limited, so the bass effect of the earphone is usually not good. Nowadays, in order to manufacture earphones with better bass effects, the industry often provides closed acoustic chambers. However, due to the large damping of the closed acoustic chambers on the sounding unit, when the sound is low-frequency, it is not easy for the sounding unit to be ins...
