摘要： In a loudspeaker, three magnets are disposed to provide magnetic gaps therebetween and a voice coil is fit therein. The magnets disposed at both sides are magnetized so that their opposing poles exhibit the same magnetic polarity. The magnet in the middle has its magnetic poles in the direction perpendicular to the line connecting the poles of the side magnets. The side magnets are fixed to a plate made of non-magnetic material. Those magnetic poles of the side magnets and the middle magnet not facing the magnetic gaps are magnetically coupled by a magnetic member.

摘要： A loudspeaker includes a diaphragm, a voice coil fixed to the diaphragm, a first magnet having a first pole surface facing an inner side of the voice coil, a second magnet located inside the inner side of the voice coil, and a first magnetic fluid provided between the first pole surface of the first magnet and the voice coil. The first magnet has the first pole surface facing the inner side of the voice coil. The second magnet has a second pole surface located inside the inner side of the voice coil such that a magnetic flux passing through the first pole surface of the first magnet crosses the voice coil in a direction perpendicular to the voice coil and a vibration direction. The first magnetic fluid contacts the first pole surface and the voice coil. The loudspeaker has a small thickness but can produce a high audio output, while preventing rolling.

摘要： An edge (29) for supporting a diaphragm assembly (100) with respect to a frame (26) is bonded to the frame (26) along the outer periphery thereof and joined to a diaphragm (27) in a position more peripherally inward than a voice coil (28) along the inner periphery thereof. The edge (29) partly overlaps diaphragm (27). This structure allows downsizing of the speaker, without reducing the sizes of a permanent magnet (21) and the edge (29).

摘要： An electro-acoustic transducer has a magnetic circuit, a frame, a diaphragm, a voice coil, a terminal, and a stopper. The frame is joined to a magnetic circuit. The diaphragm is joined to a circumferential edge of the frame. The voice coil is joined to the diaphragm and is partially provided at a magnetic gap of the magnetic circuit. The terminal is composed of a metal plate having spring property and conductivity, is partially fixed to the frame, and is electrically connected to the voice coil. The stopper is provided at an outer periphery of the metal plate of the terminal and extends from a main section of the terminal to the frame. The stopper restricts a bending range of the metal plate constituting the terminal to a level equal to or lower than a reversibility limit value of metal material constituting the terminal.
