Universal mechanical isolator that effectively decouples a vibration sensitive device such as a microphone from a support to thereby isolate the vibration sensitive device from mechanical vibrations.

A sound capture system can include a sound capture device configured for placement within a sound-generating device. The sound capture system can include a suspension system configured to suspend the sound capture device within the sound-generating device. The suspension system acoustically decouples the sound capture device from the sound-generating device. The sound capture device includes a plurality of transducers configured to generate a plurality of audio signals concurrently from sound generated by the sound-generating device. In another aspect, the sound capture system includes a signal processing circuit.

A microphone includes: a housing; a microphone unit that outputs a sound signal disposed in the housing; an elastic member mounted to the microphone unit; and a weight member mounted to the elastic member.

An image capture device and a handheld image stabilization device may each include a housing, a motor assembly, a microphone, a dampener, or any combination thereof. The housing may include a first port. The motor assembly may be attached to the housing. The motor assembly may include a plurality of motors. The microphone may be configured to detect audio waves via the first port, vibration noise of the plurality of motors via the housing, or both. The audio waves may include acoustic noise from the plurality of motors. The dampener may be coupled to the housing. The dampener may be configured to reduce the acoustic noise from the plurality of motors, the vibration noise from the plurality of motors, or both.

A receiver assembly including a receiver and an assembly housing. The receiver includes a sound outlet configured to outlet sound from the receiver. Furthermore, the receiver includes at least a first and a second outer surface and is arranged at least partly within the assembly housing. The assembly housing includes an assembly sound outlet arranged in communication with the sound outlet for outlet of sound from the receiver via the assembly outlet. The receiver assembly further includes a suspension structure having at least one suspension element, the suspension structure suspending the receiver in the assembly housing. The suspension element connects the receiver and the assembly housing, and the suspension element is formed by a sheet material and is an elongated element extending in an longitudinal direction and is configured to dampen vibration of the receiver by deflection of the suspension element in a direction transverse to the longitudinal direction.

An open audio device with a housing that is configured to be worn on the torso and an acoustic transducer carried by the housing, the acoustic transducer configured to either radiate sound outwardly of the housing or convert received sound into an electrical signal. A structure is coupled to the housing. The structure is proximate to the acoustic transducer. The structure is constructed and arranged to inhibit radiated sound or received sound from being interrupted by a flexible sheet material, such as clothing, located over the housing.

A motor may include a coil assembly, a ring, one or more magnets, and a shaft. The coil assembly may include one or more coils arranged in a circular structure. The ring may surround an outer surface of the coil assembly. One or more magnets may be adhered to an inner surface of the ring. The one or more magnets may correspond with a respective coil of the one or more coils. The shaft may extend through a center portion of the circular structure. The shaft may provide a rotational axis for the motor. The shaft may be configured to generate a natural resonance that does not overlap with an operating frequency of the motor.

A shotgun microphone unit which includes a housing, a microphone capsule, a shotgun tube having a longitudinal axis, and a shotgun mounting for mounting the shotgun tube with the microphone capsule within the housing. The shotgun mounting has an axial and a radial mounting, wherein the axial mounting is softer than the radial mounting.

The invention relates to speaker systems for high-quality sound reproduction. It provides a simplified structure of the device, improves the device manufacturability and durability. The speaker system includes the driver, the horn for reproducing low-frequency range sound (rear horn), and the horn for reproducing high-frequency and mid-frequency range sound (front horn); both horns are made in the form of a single enclosure with the capability of mounting the driver in this enclosure, while the enclosure is made of two solid parts symmetrical with respect to the plane of the central vertical section, each part represents a half of the overall profile of the front and rear horns, with no joints at the junction between the front and the rear horns.

A loudspeaker device comprising a loudspeaker unit comprising a diaphragm with a first and second surface (such as the front and rear surface of the diaphragm, respectively) and an enclosure in which the loudspeaker unit is mounted such that the first surface of the diaphragm is in acoustic communication with the surroundings of the loudspeaker device. The device further comprises an internal cavity formed in the enclosure and being in acoustic communication with the surroundings of the loudspeaker device via an acoustic element. In the device, the second surface of the diaphragm is in acoustic communication with the internal cavity. The acoustic element can be varied between a state in which sound energy generated by the loudspeaker unit in the internal cavity can be emitted to the surroundings via the acoustic element and a state in which sound energy is substantially prevented from entering the surroundings via the acoustic element.
