Mass loaded earbud with vent chamber
Intra-concha earphones are disclosed. In an embodiment, an intra-concha earphone includes a housing having a rear space divided into a back volume, a bass duct, and a vent chamber between a driver and a rear wall. The vent chamber may be acoustically coupled with the back volume through both an acoustic port and the bass duct. Furthermore, the vent chamber may be acoustically coupled with a surrounding environment through a vent port, which may be a sole acoustic opening in the rear wall. Thus, sound emitted by the driver may propagate through the acoustic port and the bass duct to meet in the vent chamber before being discharged through the vent port to the surrounding environment. Other embodiments are also described and claimed.
In-ear audio system
Techniques are described for an in-ear audio system that delivers high quality sound into an ear canal of the user using two or more waveguides. Each of the waveguides may deliver sound output by individual drivers to a consolidation zone. The sound may be mixed at the consolidation zone and delivered to the ear canal of the user.
Remote control of ear mounted audio devices
A remote controller for a sound delivery system such as hearing aids and headsets is shown and described. The remote controller has control buttons corresponding to control functions of the sound delivery system, a signal generator, a signal transmitter, and a power supply. The sound delivery system is worn on the head or ears, and includes speakers, sounding controlling elements, a signal receiver for communication with the remote controller, a power supply, and audible and/or visible beacons for implementing a locator function if misplaced or lost. The remote controller may be a stand alone, dedicated component physically separate from the sound delivery system, or alternatively, may be implemented as an application downloadable to a cellular telephone. The application causes manual controls corresponding to those of a hearing aid or stereophonic controls to appear on a screen of the cellular telephone.
Audio signal processing for noise reduction
A headphone, headphone system, and speech enhancing method is provided to enhance speech pick-up from the user of a headphone and includes receiving a plurality of signals from a set of microphones and generating a primary signal by array processing the microphone signals to steer a beam toward the user's mouth. A noise reference signal is also derived from one or more microphones via a delay-and-sum technique, and a voice estimate signal is generated by filtering the primary signal to remove components that are correlated to the noise reference signal.
Portable audio device case with power-saving features
Disclosed are techniques to improve power consumption of portable audio devices through the use of a plurality of adapters. Each of the plurality of adapters can be used to modify and/or enhance the functionality of the portable audio device. The portable audio device can include respective circuitry that is activated in response to detecting that a specific one of the plurality of adapters is coupled to the portable audio device.
Loudspeaker device
The present disclosure provides a loudspeaker device. The loudspeaker device may include an earphone core configured to transfer an electrical signal to a vibration signal; an auxiliary function module configured to receive an auxiliary signal and perform an auxiliary function; a first flexible circuit board configured to electrically connect to an audio signal wire and an auxiliary signal wire of an external control circuit, the audio signal wire and the auxiliary signal wire being electrically connected with the earphone core and the auxiliary function module, respectively through the first flexible circuit board; and a core housing configured to accommodate the earphone core, the auxiliary function module, and the first flexible circuit board. The wiring process inside the loudspeaker device provided in the present disclosure may be simplified, thereby further reducing a volume of the loudspeaker device.

Headset with membrane coupling connecting the headband to the earpieces
A headset includes an earpiece coupled to a headband with a membrane coupling. The earpiece includes an outer housing and an audio driver positioned within and coupled to the outer housing. The membrane coupling includes a membrane insert composed of a resilient material. The membrane insert is coupled to the outer housing. A connection pin may extend through a central opening of the membrane insert and into an end of the headband in order to directly couple the end of the headband to the membrane insert in order to couple the outer housing to the end of the headband. The coupling of the end of the headband to the outer housing with the membrane insert in between defines the membrane coupling. The membrane coupling is designed to allow relative movement in six degrees of freedom comprising three orthogonal degrees of translation freedom and three orthogonal degrees of rotational freedom.
Systems and methods for dynamic noise reduction
Aspects relate to systems and methods for dynamic active noise reduction including at least a sensor configured to sense a physiological characteristic of a user and transmit a physiological signal correlated to the sensed physiological characteristic, at least an environmental microphone configured to transduce an environmental noise to an environmental noise signal, a processor configured to receive the environmental noise signal, generate a noise-reducing sound signal as a function of the environmental noise signal, and, modify the noise-reducing sound signal as a function of the physiological signal, and a speaker configured to transduce a noise-reducing sound from the modified noise-reducing sound signal.
Wireless audio streaming system for swimmers and under water applications
A wireless audio streaming system for swimmers and underwater applications uses directional transmission antennas, one or more reception antennas worn on a user, and a combination of radio frequency and near-field magnetic induction communication, for streaming audio to a swimmer, buffering the streamed audio, and allowing the user to play the audio on a wireless, waterproof headset.
