Abstract: An audio headset sub-assembly (600, 700, 900, 1000, 1200, 1300, 1500) providing the operative functionality for true wireless headphones/headset (100) includes circuitry operative to effect wireless communication and audio signal processing, and a battery (212). These circuits and battery (212) are contained in a sealed enclosure (610, 710, 1210, 1310). In one embodiment, the sub-assembly (600, 700, 900, 1000, 1200, 1300, 1500) includes all electronic components for wireless communications and audio signal processing, and a battery (212), but does not include a speaker. A microphone (240) may be part of the sub-assembly (600, 700, 900, 1000, 1200, 1300, 1500) or may be external. In another embodiment, a speaker (230) is part of the sub-assembly (600, 700, 900, 1000, 1200, 1300, 1500) as well. The sub-assembly (600, 700, 900, 1000, 1200, 1300, 1500) may include several cavities (1254, 1252) and vents (1264, 1262) before and behind the speaker (230) for optimal acoustic performance.

Abstract: A wireless monophonic headset device has one ear piece, a control box, and a cable in between. The ear piece comprises a speaker and a battery. The control box includes circuitry including a short-range radio transceiver and a codec. The ear piece battery is connected to supply power to the control box circuitry by means of the cable.

Abstract: A compact, wearable wireless headset for stereo audio reproduction contains first and second ear pieces. The ear pieces each contain a battery and a speaker, and are connected by connecting means. The first ear piece receives audio information via a short range radio, and communicates left channel audio information to the second ear piece by various means, including wirelessly, by wire, and via optical communication. In some embodiments, the battery in the second ear piece supplies power to circuitry located in the first ear piece.

Abstract: A noise-cancellation wired headset device has a left ear piece, a right ear piece, a control box, first and second cables, and a connector for connecting the control box to a third cable. Each of the ear pieces comprises its own speaker, microphone and battery. The control box includes circuitry including noise cancellation circuitry and a power management unit. The left ear piece battery is connected to supply power to the power management unit by means of the first cable; and the right ear piece battery is connected to supply power to the power management unit by means of the second cable. The power management unit in the control box regulates the supplied battery power and supplies regulated power to control box circuitry. The noise cancellation circuitry is for noise cancellation processing of signals provided by the first and second microphones.
