20120285808 | KEYBOARD STRUCTURE - A keyboard structure includes a frame, a button, a first circuit unit and a second circuit unit. The frame includes at least a through hole. The button is disposed at the through hole and magnetically connected with the frame. The first circuit unit includes a first electrical contact point disposed corresponding to the button. The second circuit unit includes a second electrical contact point disposed corresponding to the first electrical contact point. When the button is pressed, the button and the frame are separated, and the first electrical contact point contacts with the second electrical contact point. | 11-15-2012 |
20150194164 | METHOD AND DEVICE FOR PROCESSING AUDIO SIGNAL - An audio signal processing method includes following steps: playing a fundamental frequency signal by a media player; calculating a first fundamental frequency sound pressure value and a first harmonic sound pressure value of the fundamental frequency signal, and calculating a second fundamental frequency sound pressure value and a second harmonic sound pressure value of the audio signal calculating a threshold sound pressure value according to the first fundamental frequency sound pressure value, the first harmonic sound pressure value, and the second fundamental frequency sound pressure value; and comparing the second harmonic sound pressure value and the threshold sound pressure value to generate a comparing result, and adjusting the second harmonic sound pressure value according to the comparing result. An audio signal processing device is also disclosed. | 07-09-2015 |

20150036865 | ELECTRICAL SIGNAL TO AUDIO SIGNAL TRANSDUCER WITH A DEFORMABLE DIAPHRAGM UNIT - An electrical signal to audio signal transducer with a deformable diaphragm unit includes a connective portion and a deformable diaphragm unit. The connective portion connects the deformable diaphragm unit with a wall of a box. The deformable diaphragm unit is linked up with a through opening of the connective portion to form a passage. Push and pull exerted on the deformable diaphragm unit by the magnetic force induced by the current flows through the voice coil can cause deformable diaphragm unit to deform and move in a reciprocating manner and thus generate audible sounds. Therefore, with the transducer of the present invention, poor performance due to the dimensional constrain may be overcome. | 02-05-2015 |

20160127823 | SPEAKER STRUCTURE - A speaker structure includes a speaker box, a speaker unit, and an elastic component. An air pressure inside the speaker box is lower than that outside the speaker box. The speaker unit is disposed on the speaker box and includes a first vibrating assembly. The elastic component is disposed in the speaker box and connected to the first vibrating assembly and the speaker box in the speaker unit. When the speaker unit operates, the first vibrating assembly of the speaker unit vibrates, and the elastic component produces a pre-force correspondingly, the total pressure of the pre-force and the air pressure inside the speaker box equals to the air pressure outside the speaker box to balance the first vibrating assembly at an equilibrium position. | 05-05-2016 |
