The invention relates to a prosthesis, orthosis or exoskeleton device (a bionic limb system device) for restoring lost functionality to a patient that suffers from at least partial loss of a limb, the device comprising a sound sensing system that communicates with a controller to generate a signal to control the device which can include a defined sensing element, a defined type of a sensor, of a communication interface and/or which can be insulated and/or wherein a controller can command an actuator and/or set a defined parameter. The device can be controllable by a defined sound; it can be coupled with an electrocomponent and/or mechanocomponent. A prosthesis, orthosis or exoskeleton device control method and a sonometry method are proposed.

An apparatus for use with an electronic device having a microphone. The apparatus comprises a structure configured to detachably couple to the device, and a generator supported by the structure. The generator is configured to generate a force that acts on the microphone and renders the microphone unresponsive to voice sounds.

An electromechanical transducer includes: a structural portion configured such that two pairs of magnets magnetized in opposite directions, a yoke configured to guide magnetic fluxes from the magnets, and a coil configured to receive a supplied electric signal are located integrally; an armature having an inner portion penetrating an internal space of the structural portion and outer portions protruding from the inner portion toward both sides in a first direction, forming, together with the structural portion, a magnetic circuit through regions of the inner portion facing the two pairs of magnets, and configured to displace in a second direction perpendicular to the first direction by magnetic force of the magnetic circuit; and a pair of elastic members each located on both sides of the armature in the second direction, and configured to provide, to the armature, restoring force according to relative displacement of the armature corresponding to the structural portion.

An apparatus for comprehensive perception of sound, preferably a cushion, where vibration and sound is produced with a mechanical device wrapped inside a padding, wherein (a) the device radiates sound by generating mechanical vibration directly to the padding that can be felt and listened on the outer surface of the padding, (b) the device radiates airborne sound through the padding, (c) in order to avoid acoustical and mechanical resonances, the padding includes an acoustically denser and lossy layer and a layer that is acoustically less dense and porous, and (d) the device includes at least one board, and the vibration of the boards is generated using at least one vibrating mechanical actuator.

Systems and methods are provided herein for balancing of outputs from playback devices playing audio content in synchrony. In one embodiment, the balancing of outputs may involve receiving a first audio signal to be played by a first playback device, determining a first limiting result by applying to a second audio signal a limiting function associated with a second playback device, determining a limiting function based on the first limiting result, and configuring the first playback device to apply the determined limiting function when playing the first audio signal. In some cases, the first and second playback devices may be configured to play the first and second audio signals, respectively, in synchrony.

The present embodiments relate to techniques (300) and apparatuses (100, 500) for implementing a flexible transducer for soft-tissue audio production. These techniques (300) and apparatuses (100, 500) enable an audio-production device (102) having a flexible transducer (116, 402) conformed to a person's pinna to create audio within the person's external ear canal.

A dynamic acoustic impedance matching device for an acoustic signal transmitted or received in a medium by a transducer includes a particle flow in an acoustic signal path of the transducer. The particle flow has an acoustic impedance between an acoustic impedance of the transducer and an acoustic impedance of the medium.
