摘要： A sinusoidal waveform generation circuit is configured to continuously control a voltage applied to a gate of a MOSFET to change an output current in the form of a sinusoidal wave by utilizing, as an electric characteristic specific to the MOSFET, a characteristic between a voltage applied to a gate of a MOSFET and an output current. The waveform of the sinusoidal wave generated by the sinusoidal waveform generation circuit is not a combination of a plurality of linear lines but is continuous and smooth. As a result, noises generated by the sinusoidal waveform generation circuit can be reduced.

摘要： The outer face of a case which accommodates a whole microphone is coated by a material having a heat conductivity which is lower than that of a metal, and a material transforming temperature which is higher than the charge dissipating temperature of a dielectric layer for forming an internal electret, and which is higher than 260° C., so that the internal temperature rise can be mitigated by the thermal resistance and the thermal capacity of the whole interior. When a microphone is attached to an application equipment, particularly, the microphone may be passed through a reflow solder bath for a short time period. A heat-resistant structure which can prevent the function from being impaired by a high temperature in the period is provided.
