摘要： The present invention 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 invention 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.

摘要： A loudspeaker (1) comprising a diaphragm (2), a voice coil (10) mounted on the diaphragm (2) to move with the diaphragm (2), a chassis (4), and a spider (20) is disclosed. The spider (20) extends across a gap between the chassis (4) and the voice coil (10) and comprises a plurality of legs (36), each leg (36) extending radially across at least a portion of the gap. The diaphragm (2) is configured to move from a neutral position to an extended position. When the diaphragm (2) is in the neutral position the cross-sectional shape of each leg (36) follows a line which varies in height with respect to a reference plane, said line comprising first, second and third curves, the second curve being located in between the first and third curves. Either the first and third curves are convex and the second curve is concave, or the first and third curves are concave and the second curve is convex. Thus, the spider (20) may have legs (36) having an ‘m’ or ‘w’ shaped profile in at least one region of the leg (36).

摘要： A structure for fixing a membrane to a carrier including a carrier; a suspended structure; and a holding structure with a rounded concave shape which is configured to fix the suspended structure to the carrier and where a tapered side of the holding structure physically connects to the suspended structure is disclosed. A method of forming the holding structure on a carrier to support a suspended structure is further disclosed. The method may include: forming a holding structure on a carrier; forming a suspended structure on the holding structure; shaping the holding structure such that it has a concave shape; and arranging the holding structure such that a tapered side of the holding structure physically connects to the suspended structure.

摘要： A sound producing package structure includes a first sub-package structure and a second sub-package structure. The first sub-package structure includes a first substrate having a first opening and a first chip including a first membrane, wherein a first cavity is formed between the first membrane and the first substrate. The first sub-package structure and the second sub-package structure are stacked, and the second sub-package structure includes a second substrate and a second chip. The second substrate is connected to the first substrate and has a second opening. The second chip includes a second membrane, wherein a second cavity is formed between the second membrane and the second substrate. A gap, connected to the first opening and the second opening, is formed between the first substrate and the second substrate, such that an ambient of the sound producing package structure, the first cavity and the second cavity are connected.

摘要： A robust MEMS transducer includes a kinetic energy diverter disposed within its frontside cavity. The kinetic energy diverter blunts or diverts kinetic energy in a mass of air moving through the frontside cavity, before that kinetic energy reaches a diaphragm of the MEMS transducer. The kinetic energy diverter renders the MEMS transducer more robust and resistant to damage from such a moving mass of air.

摘要： A beamforming microphone array may be integrated into a wall or ceiling tile as a single unit. The beamforming microphone array includes a plurality of microphones that picks up audio input signals. In addition, the wall or ceiling tile may include an acoustically transparent outer surface on the front side of the tile, and the beamforming microphone array picks up the audio input signals through the outer surface of the tile. The beamforming microphone array may be coupled to the tile as a single unit and may be integrated into the back side of the tile.

摘要： Presented herein are contaminant-proof microphone assemblies for use with devices/apparatuses, such as auditory prostheses, that include one or more microphones disposed within a housing. A contaminant-proof microphone assembly in accordance with certain embodiments presented herein includes a microphone, a microphone plug, and a contaminant-proof membrane. The microphone plug has a first end coupled to the microphone and a second end that is configured to be positioned adjacent the contaminant-proof membrane. As such, the microphone plug is disposed between a sound inlet of the microphone and the contaminant-proof membrane. The microphone plug may be configured to mate with the housing or a gasket attached to the housing.

摘要： A loudspeaker system with viscoelastic material affixed between two flexible panels is disclosed. The loudspeaker system dissipates the energy of motion, resulting in less pronounced resonant peaks. The effect may be especially evident at high frequencies, where energy is dissipated over many cycles in a shorter period of time. Also disclosed are the method of making the loudspeaker system and a method of using the loudspeaker system.
