摘要： The present invention provides a unidirectional condenser microphone unit that can suppress the occurrence of howling. In a unidirectional condenser microphone unit, a diaphragm 20 extended across a support ring 21 and a backplate 30 supported by an insulation cylinder 50 are arranged opposite each other via a spacer ring 40. A backside air chamber 31 is provided between the backplate 30 and the insulation cylinder 50. When the density of air is defined as ρ, sound velocity is defined as c, the effective vibration area of the diaphragm 20 is defined as S, and the volume of the backside air chamber 31 is defined as V, a stiffness s1 of the backside air chamber expressed by (ρ×c2×S2)/V is increased on the basis of the volume V of the backside air chamber to shift a resonance frequency of a unidirectional component contained in unidirectivity up to a frequency near a high-frequency reproduction limit.

摘要： It is an object of the present invention to use a simplified structure to improve a strength of a neck portion of a conical diaphragm in the vicinity of a voice coil fixing section, thereby inhibiting an undesired dividing vibration in a speaker device. The speaker device of the present invention comprises: a generally conical diaphragm having an opening formed in a generally central position thereof; a voice coil bobbin fixed in the inner circumferential portion of the foregoing opening of the diaphragm; and a diaphragm reinforcing annular member disposed near a fixing section fixing together the diaphragm and the voice coil bobbin. The annular member includes, in the form of an integrally formed body, a diaphragm reinforcing portion having an inclined surface which contacts an inclined surface of the diaphragm close to the inner circumferential portion thereof and is fixed to the inclined surface of the diaphragm by virtue of an adhesive agent, and a cylindrical portion having a liquid holding portion which is formed between the voice coil bobbin and the annular member and is filled with the adhesive agent.
