发明名称 Speaker system
摘要 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.
