摘要： Voice coil actuators and loudspeakers containing same. The voice coil actuators include moving voice coil assemblies that have multiple segments. Each segment of a moving voice coil assembly is separately controlled by an amplifier, one channel of an amplifier, and combinations thereof utilized in combination with a position sensor that senses the position of the moving voice coil assembly. By this arrangement, the voice coil actuators produce a linear force per unit current throughout the range of motion while obtaining the benefits and advantages associated with both over-hung and under-hung voice coil actuator designs.

摘要： The present disclosure relates to a flexible printed circuit board (FPCB) diaphragm microspeaker having a magnetic field pair structure, and more particularly, to a microspeaker using an FPCB diaphragm in which magnetic fields are arranged in pairs up and down to increase the strength of a horizontal component of the magnetic fields. The microspeaker includes: a FPCB diaphragm in which a conductive coil pattern is formed on a non-conductive film; an upper magnetic circuit disposed above the FPCB diaphragm and having a yoke and a magnet; and a lower magnetic circuit disposed below the FPCB diaphragm and having a yoke and a magnet. When an electrical signal is applied to the coil pattern of the FPCB diaphragm, the FPCB diaphragm vibrates to generate sound by mutual electromagnetic force between the upper magnetic circuit and the lower magnetic circuit.

摘要： The present disclosure relates to a bone conduction speaker and its compound vibration device. The compound vibration device comprises a vibration conductive plate and a vibration board, the vibration conductive plate is set to be the first torus, where at least two first rods inside it converge to its center; the vibration board is set as the second torus, where at least two second rods inside it converge to its center. The vibration conductive plate is fixed with the vibration board; the first torus is fixed on a magnetic system, and the second torus comprises a fixed voice coil, which is driven by the magnetic system. The bone conduction speaker in the present disclosure and its compound vibration device adopt the fixed vibration conductive plate and vibration board, making the technique simpler with a lower cost; because the two adjustable parts in the compound vibration device can adjust both low frequency and high frequency area, the frequency response obtained is flatter and the sound is broader.
