A method of determining bone vibrations includes providing at least one earpiece, transmitting substantially coherent light toward an outer surface of a user's body using the earpiece, receiving reflected light from the outer surface of the user's body using the earpiece, and determining bone vibration measurements using the earpiece.

A wireless earpiece for digital rights management is provided. The wireless earpiece includes a processor disposed within the ear piece housing, a speaker operatively connected to the processor, a storage medium disposed within the ear piece housing and operatively connected to the processor, and a wireless transceiver disposed within the ear piece housing and operatively connected to the processor. The processor may be configured to access audio files stored on the storage medium to play the audio files over the speaker. The processor may be configured to provide a digital rights management feature for one or more of the audio files. The processor may be further configured to access an audio stream conveyed to the earpiece through the wireless transceiver. The processor may be further configured to provide a digital rights management for the audio stream.

Ear buds are provided that communicate wirelessly with an electronic device. To determine the current status of the ear buds and thereby take suitable action in controlling the operation of the electronic device and ear buds, the ear buds may be provided with sensor circuitry. The sensor circuitry may include proximity sensors. The ear buds may each have a housing with a main body portion that is configured to be inserted into the ear of the user and an elongated stem portion that extends from the main body portion. The proximity sensors may include sensors on the main body and sensors on the stem. The proximity sensors may be light-based sensors that emit light that passes through the housing.

A sound controlling system including a user terminal having a sound source, a wireless communication device, a digital to analog converter (DAC) and first processing electronics. The first processing electronics are configured to: provide data of a backing sound to the sound source; control the sound source to generate a sound signal based on the data; receive a first input instruction including a first instruction to transmit the sound signal and a second instruction to play back the backing sound; provide the sound signal to the wireless communication device as the first input instruction being the first instruction, and provide the sound signal to the DAC as being the second instruction; control the wireless communication device to convert the sound signal to a wireless signal and transmit the wireless signal; and convert the sound signal from a digital signal to an analog signal for play back of the backing sound.

Headphones, with one or two earcups (10), wherein each earcup (10) includes an electroacoustic sound generator (12) having a membrane (13) configured to radiate sound; a rear wall (14), wherein the membrane is arranged between the rear wall (14) and the user’s ear when the headphones are used, wherein a rear side of the membrane (13) faces a rear volume (26) between the membrane (13) and the rear wall (14) and a front side of the membrane (13) faces a front volume (20) between the membrane (13) and the user’s ear; and a tube (18) having a first and a second opening and an inner volume, wherein the tube (18) is arranged between the membrane (13) and the rear wall (14), and wherein the first opening of the tube (18) faces the membrane (13) and the second opening of the tube faces a peripheral environment behind the rear wall (14).

The present disclosure relates to a system 10 comprising an ear cushion 20 for a headset 100, a fluid supply 30 and a fluid guide device 40 connected to the ear cushion 20. The present disclosure further relates to an ear cushion 20 for a headset 100, a fluid guide device 40 for a headset 100. Moreover, the present disclosure relates to a headset 100 as well as to a headgear 200 comprising such a system 10.

A modular headphone system that can afford the wearer configurable choices of hearing protection and quality sound delivery for music and programming is provided. In an embodiment, a modular headphone includes a headband and an earpiece mounted to the headband. The earpiece comprises a can comprising a speaker, the can secured to the headband. A removable and replaceable music ear cup is removably mountable to the can to overlie the speaker. A removable and replaceable hearing protection/sound amplification (HP/amp) ear cup is removably mountable to the can to overlie the speaker.
