|20140369534||SOUND PICKUP SYSTEM AND TERMINAL DEVICE USING THE SAME - A sound pickup system is disclosed. The sound pickup system includes a screen, an accelerometer attached to the screen, and a pre-processing module electrically connecting with the accelerometer. The screen is configured to detect a vibration caused by sound waves, the accelerometer is configured to receive the vibration detected by the screen and convert the vibration into an acceleration signal, and the pre-processing module is configured to receive the acceleration signal, and process the acceleration signal then convert the processed acceleration signal into a voice signal.||12-18-2014|
|20140161289||Silicon Condenser Microphone - A silicon condenser microphone is disclosed. The microphone includes a transducer, an IC chip, a first board, a second board spaced from the first board by a frame, and a third board located between the first board and the second board. A cavity is accordingly formed by the first board, the frame and the third board to accommodate the transducer and the IC chip. The IC chip is electrically connected to a surface of the third board facing the second board. The microphone provides an enlarged back volume to the transducer and provides the transducer with a shield against electro-magnetic interference. A manufacturing process is also disclosed.||06-12-2014|
|20140056465||Speaker - A speaker includes a vibrating unit, and a magnetic circuit unit. The vibrating unit includes a diaphragm, an elastic plate coupled with the diaphragm, and a voice coil electrically connecting to the elastic plate. The vibrating unit is mounted to and positioned by the magnetic circuit unit. A projection of the diaphragm on the magnetic circuit unit is disposed within an outline of the magnetic circuit unit. The speaker has no frame or any structure with a frame configuration, which makes the magnetic circuit unit larger and more powerful.||02-27-2014|
|20140056447||Speaker - A speaker includes a vibrating unit, a gasket and a magnetic circuit unit. The vibrating unit includes a diaphragm, and a voice coil electrically connecting to the elastic plate. The gasket supporting the position portion of the diaphragm includes a number of slots serving as air leaking holes for communicating interior of the speaker with exterior space. The combination of the diaphragm and the gasket is mounted to and positioned by the magnetic circuit unit. A projection of the diaphragm on the magnetic circuit unit is disposed within an outline of the magnetic circuit unit. The speaker has no frame or any structure with a frame configuration, which makes the magnetic circuit unit larger and more powerful.||02-27-2014|
|20140023224||Speaker - A speaker includes a holder having a receiving cavity and an acoustic hole communicating with the receiving cavity, a magnetic circuit system received in the receiving cavity of the holder, and a guiding portion attached on the holder. Wherein at least a part of the guiding portion is exposed from an outer surface of the holder and disposed near the acoustic hole for guiding magnetic leakage leaked from the magnetic circuit system to attract the ferromagnetic material dust near the acoustic hole. The performance of the speaker is improved.||01-23-2014|
