摘要： Earphones including condenser type electroacoustic transducers exhibit compatibility between an open type earphone mode and a closed type earphone mode for improving convenience. An exemplary earphone includes a diaphragm, at least one fixed electrode constituting a capacitor with the diaphragm, a housing accommodating the diaphragm and the at least one fixed electrode, the housing having an interior and an exterior, a sound conduit protruding forward from the housing, communication holes establishing communication between the interior and the exterior of the housing, and an opening and closing mechanism to open and close the communication holes. The sum of the volume of the interior space of the sound conduit and the volume of the space in a front of the diaphragm in communication with the interior space of the sound conduit in the interior space of the housing is smaller than the volume of the space in a rear of the diaphragm in the interior space of the housing.

摘要： In a microphone holder, a microphone can be attached and detached by a one-touch operation and to be securely held. A microphone grip is pressed into between clamp arms in a state where front ends are opened. This causes the microphone grip to press rear ends of the clamp arms to swing the front ends in closing directions. Thus, the microphone can be attached and detached by a one-touch operation without causing collision noise and the like.

摘要： The present invention relates to a capacitor microphone which is characterized that even in a microphone with a small diameter such as a lavalier microphone, the noneffective electrostatic capacitance enables to be decreased and a better signal-to-noise ratio enables to be obtained. As shown in FIG. 2, in the capacitor microphone in which a vibration plate 10 strained and fixed on a support ring 11 and a charge back-plate 20 supported on one end-side of a cylinder base 21 face each other and are disposed through a spacer forming a gap, the spacer 30A having at least three spacer pieces, in which the each spacer piece has the same thickness and is disposed apart from the adjacent spacer pieces at generally equal angle on the same circumference, in place of the ring-shaped spacer.
