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. |

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.
