    摘要： A speaker comprising a first rod magnet having a longitudinal direction, a second rod magnet having a longitudinal direction parallel with the longitudinal direction of the first rod magnet, a third rod magnet forming a second magnetic gap between it and the first rod magnet, a diaphragm vibrating in the vibrating direction, a housing for storing the first rod magnet, the second rod magnet, the third rod magnet and the diaphragm, and voice coils bonded to the diaphragm and arranged in first and second magnetic gaps. The second rod magnet has a longitudinal direction parallel with the longitudinal direction of the first rod magnet, and has the opposite end faces in the longitudinal direction. The third rod magnet has a longitudinal direction parallel with the longitudinal direction of the first rod magnet, and has the opposite end faces in the longitudinal direction. The diaphragm is located between the first and second rod magnets and between the first and third rod magnets. The housing forms a first space surrounded by one of the opposite end faces of the second rod magnet and one of the opposite end faces of the third rod magnet, and forms a second space surrounded by the other of the opposite end faces of the second rod magnet and the other of the opposite end faces of the third rod magnet. The housing is composed of a nonmagnetic body and supports the outer circumference of the diaphragm. First and second sound radiating holes respectively facing the first and second spaces are formed in the housing. This speaker is thin and can deliver big sound.

    摘要： A loudspeaker includes a first bar magnet having a longitudinal direction, a second bar magnet having a longitudinal direction parallel to the longitudinal direction of the first bar magnet, a third bar magnet forming a second magnetic gap between the first bar magnet and the third bar magnet, a diaphragm arranged to vibrate in a vibrating direction, a case accommodating the first bar magnet, the second bar magnet, the third bar magnet, and the diaphragm , and the voice coil fixed to the diaphragm and located in the first and second magnetic gaps. The second bar magnet has a longitudinal direction parallel to the longitudinal direction of the first bar magnet, and has both ends in the longitudinal direction. The third bar magnet has a longitudinal direction parallel to the longitudinal direction of the first bar magnet, and has both ends in the longitudinal direction. The diaphragm is located between the first and second bar magnets and between the first and third bar magnents. The case is made of non-magnetic material and holds an outer periphery of the diaphragm. The case forms a first space surrounded by the case, one of the both ends of the second bar magnet, and one of the both ends of the third bar magnet. The case forms a second space surrounded by the case, another one of both ends of the second bar magnet, and another one of both ends of the third bar magnet. First and second sound holes are provided in the case and communicate with the first and second spaces, respectively. The loudspeaker is thin but outputs large sounds.

    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.
