  • Patent number: 7062053
    Abstract: Herein disclosed is a condenser microphone structure which comprises a microphone housing, a condenser microphone accommodated in the microphone housing to produce a sound signal indicative of a voice sound, first and second terminal connecters provided on the microphone housing in the neighborhood of each other under an insulated state from each other, each of the first and second terminal connecters including a helical spring portion, and an end portion integrally formed with the helical spring portion, the helical spring portion and the end portion being made of an electrically conductive material, the end portions being electrically connected with the condenser microphone to discharge the sound signal from the condenser microphone through the first and second terminal connecters, and an insulating member accommodated in the microphone housing to retain the condenser microphone and the first and second terminal connecters with the microphone housing and to insulate the first terminal connecter from the sec

  • Patent number: 6748091
    Abstract: To provide a capacitor microphone without molds or dies formed with a high accuracy for the manufacturing of spring terminals of the capacitor microphone, this invention provides a capacitor microphone including spring terminals attached to an insulator so as to make the spring terminals contact and conductive with contact points provided at the inside and the outside of a capacitor microphone main body. The spring terminals are provided with leg portions each formed by a pair of wire rods having elasticity which protrude in directions separating to each other toward the outside. The spring terminals can be manufactured in a short time and at a low cost and realize a stable electrical connection.
