Patent number: 6188774Abstract: A flat loudspeaker of superior quality for use in audio appliances, in which loudspeaker the generation of abnormal sounds is eliminated by placing a voice coil with a high accuracy in the magnetic gap. A diaphragm is split into a main diaphragm (11) and a sub-diaphragm (12); a voice coil (8) is connected to the inner circumference of the main diaphragm (11) whose inner diameter is substantially identical with the diameter of the magnetic gap (5). In the loudspeaker, the voice coil (8) is placed in a right positioning without inclination and eccentricity relative to the magnetic gap (5), abnormal sounds are eliminated, and a thinner configuration and a lower rejection rate are made compatible.Type: GrantFiled: July 13, 1999Date of Patent: February 13, 2001Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takashi Sabato, Kazuhiro Oshika

Patent number: 5932850Abstract: A speaker system provides good acoustic characteristics for use in visual equipment, by controlling the turbulence in mid-range of response frequency characteristics to be flat so as to produce an excellent speech articulation. This is accomplished by coupling an acoustic pipe to the front of a speaker unit to guide sound waves through an opening of generally rectangle shape. A resonance absorption section is formed by a tube, one end of which forms a hole for absorbing sound facing to a sound path running within the acoustic pipe from the front of speaker unit to an opening, and a cavity having a small gap along the edge, except the area where is coupled through with the other end of tube. By constructing the speaker system in this way, the width of band to be absorbed and the Q of a dip can be controlled to suppress the peaks and dips, thereby providing a speaker system of good acoustic characteristics where the response frequency characteristics are flat and the speech articulation is excellent.Type: GrantFiled: April 29, 1998Date of Patent: August 3, 1999Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takashi Sabato, Toshihide Takizawa, Teruo Doi, Kazuki Honda, Takafumi Yuasa
