20150208160 | TREBLE AND BASS HEADPHONE STRUCTURE - A treble and bass headphone structure comprises: a headphone back cover; a headphone support frame contacted with the headphone back cover; a dynamic bass sound unit contacted with the headphone back cover; a partition contacted with the dynamic bass sound unit; a headphone front cover contacted with the partition; a film ribbon tweeter sound unit entered and accommodated in an accommodating slot of the headphone front cover from the headphone front cover; and a soft ear-cover contacted with the headphone front cover; | 07-23-2015 |
20140072153 | SIMULATED SOUND FIELD EARPHONE - A simulated sound field earphone includes a right ear unit, a left ear unit, a battery-containing analog sound field signal connective module and a simulated sound field selector. The right ear unit includes at least two sound generating units and the left ear unit also includes at least two sound generating units. Therefore, the sound field signal connective module can be used to select from at least two types of sound fields through the simulated sound field selector. | 03-13-2014 |
20140064548 | EARPHONE WITH TENSION DIAPHRAGM - 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. | 03-06-2014 |
20130259286 | Negative pressure earphone - A negative pressure earphone includes a main body, a cover portion, a silica gel earplug, a filtering net and a moving coil sound unit. The silica gel earplug is fitted to the protruding end of the main body. The filtering net is provided on the opening of the protruding end and the moving coil sound unit is disposed inside the main body. The cover portion is fitted to the other end of the main body. A sealing framework portion is disposed inside the main body and the moving coil sound unit is fitted to the sealing framework portion. A negative pressure portion is disposed on the sealing framework portion. The negative pressure earphone of the present invention is structurally simple and water resistant and does not have to have an opening in its cover portion. | 10-03-2013 |
