    摘要： An electroacoustic transducer has a magnetic circuit, a frame combined with the magnetic circuit, a diaphragm combined with a periphery of the frame, a voice coil, a terminal, and a holder covering the frame. The voice coil is combined with the diaphragm and a part of the voice coil is arranged in a magnetic gap of the magnetic circuit. The terminal, made of a metal plate having spring property and electric conductivity, electrically connects an outside circuit and the voice coil utilizing spring pressure generated when the metal plate is bent. The holder forms a stopper for restricting a bend of the metal plate forming the terminal to within a reversible limit of a metallic material.

    摘要： A loudspeaker includes a magnetic circuit having a magnetic gap, a frame coupled to the magnetic circuit, a voice coil having a first end positioned in the magnetic gap and a second end opposite to the first end, and a diaphragm coupled to the second end of the voice coil and the frame. The voice coil has a center axis provided through the first end and the second end. The diaphragm has a first portion in which the center axis of the voice coil is provided. The first portion of the diaphragm is provided inside the voice coil. The diaphragm further has a second portion outside the voice coil. One of the first portion and the second portion of the diaphragm has a cross section in a plane including the center axis, and the cross section of the one of the first portion and the second portion of the diaphragm has an elliptic-arc shape. This loudspeaker has a small thickness, has a high sound pressure level in a high frequency range, and secures a wide reproduction range in high frequencies.
