Abstract:
1. A structure around a speaker unit, the structure comprising: a speaker unit comprising a frame supporting a magnet and a vibrating cone; and a back sound screening section for screening out indirect sounds which come from the back of the speaker unit and travel forward, the back sound screening section including a sound transmitting hole portion; wherein the frame of the speaker unit is mounted to the back sound screening section through a vibration absorbing member which is remote from said vibrating cone to isolate the speaker unit from the back sound screening section so that the frame of the speaker unit can move freely in the direction in which the vibrating cone vibrates with strokes being substantially the same as the amplitude of the vibrations of the vibrating cone and indirect sounds are not transmitted from the frame of the speaker unit to the back sound screening section, and wherein the back sound screening section and the vibration absorbing member can screen out indirect sounds and transmit only direct sounds which come from the front of the speaker unit.
