Patent ID: 8744111

Claim:
An earphone with tension diaphragm, comprising: a front portion ( 1 ); a rear portion ( 2 ), fitted to the front portion ( 1 ); a silicone gel earplug ( 3 ), fitted to a protruding portion ( 5 ) of the front portion ( 1 ); a filtering net ( 4 ), attached at a proximal end of the protruding portion ( 5 ); a sound generating unit ( 6 ), disposed inside the front portion ( 1 ), having a vibration diaphragm actuated by an attached voice coil when an audio current is passed through the coil; a tension diaphragm ( 7 ) disposed inside the rear portion ( 2 ), wherein the tension diaphragm ( 7 ) comprises a flat base part ( 12 ), a frame ( 15 ), an upper part ( 14 ), a lower part ( 16 ) and a circumferential supportive part ( 13 ), and wherein the upper part ( 14 ) and lower part ( 16 ) are made of a composite material, and wherein the circumferential supportive part ( 13 ) is circumferentially provided around the flat base part ( 12 ) and the frame ( 15 ) is provided on the outmost portion of the flat base part ( 12 ); a decorative portion ( 8 ) fitted to a distal end of the rear portion ( 2 ), and an air outlet ( 11 ) formed on the decorative portion ( 8 ), thereby as a user pushes the earphone into his ear, the vibration diaphragm of the sound generating unit has a deformation and thus an air turbulence is generated, and the air turbulence then causes a deformation of the tension diaphragm, which in turn eliminates strange and unpleasant noises generated.
