Abstract

An earphone with tension diaphragm includes a front portion, a rear portion, a silicone gel earplug, a filtering net and a sound generating unit. As a user pushes the earphone into his ear, the diaphragm of the sound generating unit has a deformation and thus an air turbulence would be generated. This air turbulence would then cause a deformation of the tension diaphragm and this deformation would in turn eliminate the strange and unpleasant noises generated as a user pushes an earphone into his ear. Therefore, better audio signals may be achieved and a better low-frequency effect may be reached. Also, because the earphone of the present invention is water-resistant, it may be used under water. In addition, other water-resistant earphones on the market do not have such tension diaphragm.

Claims (12)

1. 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.

2. The earphone with tension diaphragm as in claim 1 , wherein the flat base part ( 12 ) is a metallic membrane, a macromolecular membrane or an organic membrane and may have a variety of shapes to choose from.

3. The earphone with tension diaphragm as in claim 1 , wherein the circumferential supportive part ( 13 ), flat base part ( 12 ), upper part ( 14 ) and lower part ( 16 ) may have smooth surfaces or protruding patterns.
