PURPOSE:To increase the compliance of a support system sufficiently without complicating the constitution and causing any defect due to abnormal sound by providing an opening of dust cap to a semicircle part opposite to a semicircle provided with two lead wires of a diaphragm. CONSTITUTION:Two lead wires are provided to one semicircle of the diaphragm 9 and an opening hole 10 is provided to a dust cap 11 corresponding to the other semicircle. Thus, the compliance of the support system is increased sufficiently without complicating the constitution and without causing any defect of abnormal sound due to the asymmetry of the diaphragm.
