摘要： An acoustic transducer comprises one or more electromagnetic motors that drive one or more sets of multiple diaphragms to provide acoustically efficient loudspeaker systems having dimensions that allow use in applications that would be difficult or impossible with traditional transducers. The diaphragms may be driven directly, inertially or fluidically. If diaphragms are driven by rods that pass through holes in the diaphragms, noise may be generated by air that leaks through the pass-through holes. This noise may be reduced or eliminated by measures that reduce or eliminate the air leakage.

摘要： A speaker includes a housing and four substantially similar electro-acoustic drivers secured inside the housing. The drivers are driven by substantially the same audio signal and are arranged such that the net mechanical vibrational force between the drivers and the housing is substantially zero. Four substantially similar passive radiators are secured inside the housing and driven by acoustic energy from the four drivers. The passive radiators are arranged such that the net mechanical vibrational force between the passive radiators and the housing is substantially zero.

摘要： A dual magnetic loop type receiver is composed of a yoke molding, a ferrite yoke, an annular magnet, a magnetic pole member, a vibration panel, a ferrite core, and a circular plate. While the receiver is operated, the annular magnet and the ferrite core and the ferrite yoke cause the receiver to produce an inner magnetic loop that interacts with the inner voice coil, and an outer magnetic loop that interacts with the outer voice coil such that the receiver generates vibration and sound.

摘要： When a sound signal is received, a sound wave generated on an upper surface of a vibration plate is transmitted to a sound collection portion through a first air passage, and a sound wave generated on a lower surface of the vibration plate is transmitted to the sound collection portion through a second air passage. The sound waves generated above and below the upper and lower surfaces of the vibration plate are about 180 degrees out of phase from each other and substantially cancel each other which minimize or prevent howling.

摘要： A vibrating plate is mounted in a case, and a first coil is secured to the vibrating plate. A magnetic circuit composition is mounted in the case. The magnetic circuit composition comprises a yoke having a flange and a core formed on the flange, an annular magnet mounted on the flange of the yoke, and a top plate comprising an annular portion and a cylindrical portion projection from a peripheral portion of the annular portion. The magnetic circuit composition is resiliently supported in the case. A coil holding plate is secured to the case, and a second coil is secured to the coil holding plate. The first coil is inserted in a first magnetic gap formed in the magnetic circuit composition and the second coil is inserted in a second magnetic gap formed in the magnetic circuit composition.
