| 20120093331 | EARPHONE - Provided is an earphone, including an earphone body and an earphone cap. The earphone body includes an earphone shell forming a sound cavity and disposing a sound-guiding pipe. The sound-guiding pipe disposes at least one through hole. The earphone cap is rotatably mounted on the earphone body and includes a main body and a barrel. The barrel is located on the inside of the main body and arranged to encompass the sound-guiding pipe. The barrel disposes at least one opening, which is arranged to be aligned or misaligned with the part or whole of the through hole. The earphone of the present invention can make the opening be aligned or misaligned with and the part or whole of the through hole by rotating the earphone cap, thereby varying the pressure of the sound cavity to attain the object of adjusting sound effect. | 04-19-2012 |
| 20120093332 | ADJUSTABLE AUDIO HEADPHONE - Provided is an adjustable audio headphone, including a headphone body, a damping object and a pressing mechanism. The headphone body includes a headphone shell, which forms a sound cavity in inside thereof and a receiving chamber on one end thereof. A bottom surface of the receiving chamber forms a through hole communicated with the sound cavity. The damping object is made of compressible material such as sponge, elastic plastic, textile and so on and. The damping object is placed into the receiving chamber of the headphone shell. The pressing mechanism is mounted on the headphone shell and is capable of pressing the damping object. The adjustable audio headphone of the present invention can compress the damping object to change the density of the damping object by employing the pressing mechanism, thereby varying the pressure of the sound cavity and realizing the object of adjusting the audio thereof. | 04-19-2012 |
| 20120113329 | LASER PROJECTOR - A laser projector has a cursor control unit, a main control unit, a laser generator and a scanning lens. The cursor control unit is used to generate and transmit cursor signals; the main control unit is used to obtain and process video signals and the cursor signals, both of which are combined into cursor video signals and transmitted; the laser generator is coupled to the main control unit for generating and projecting laser beam according to the cursor video signals; and the scanning lens is coupled to the main control unit for receiving the laser beam and projecting it outward in a predetermined scanning manner. The laser projector of the present invention uses laser resource itself to project laser cursor generated by the cursor control unit onto a screen, so that it is unnecessary to additionally use a laser pointer, and the operation of the laser projector is relatively simple. | 05-10-2012 |
| 20120114160 | TUNABLE EARPHONE - Provided is a tunable earphone, including an earphone shell, a sound generation device and a tuning device. The earphone shell disposes a pivot hole and a number of tuning holes. The sound generation device is located in the earphone shell. The tuning device includes a tuning member and a damping body. The tuning member includes a covering body being adjustable for covering all or part of the tuning holes and a connecting rod. One end of the connecting rod is fixedly connected to the covering body, and the other end of the connecting rod extends out of the earphone shell. The damping body is placed into the corresponding tuning hole for auxiliary adjusting the pressure of the low sound inner cavity, so that the present tunable earphone can generate the different sound effect of the low frequency to satisfy the different users' needs. | 05-10-2012 |
