Abstract:
A speaker apparatus comprising:a speaker unit including a magnet, a frame and a diaphragm, said speaker unit electromechanically transducing an input low-frequency signal into oscillation to oscillate said diaphragm, and to generate and radiate sound waves from a front surface of said diaphragm; a speaker housing having a substantially cylindrical shape, said speaker housing having such a structure that said speaker unit is secured onto one end surface of said cylindrical shape of said speaker housing so as to substantially cover said speaker unit except for front and back surfaces of said diaphragm, and said speaker housing having an opening in another end surface of said cylindrical shape thereof; a support bar extending and having one end secured to a back surface of said magnet of said speaker unit; and a weight secured to another end of said support bar, said weight holding said support bar in a substantially vertical direction and grounding said magnet acoustically and virtually, thereby attenuating and suppressing oscillation transmitted from said magnet to said support bar.
