Thereby the temple is assembled with the Bluetooth earphone conveniently and various combinations of materials such as metals and plastic are used to increase Bluetooth glasses styles. Moreover, an adjustment knob is mounted to the earphone body of the Bluetooth earphone for switching between a front broadcast hole and a rear broadcast hole through which sounds from a speaker are output.

A wireless earring assembly for discretely streaming audio into a user's ears includes a pair of earrings that each includes an ornament, a stud extending away from the ornament and a retainer that is slidable onto the stud. A pair of audio units is each integrated into the ornament of a respective one of the earrings. Each of the audio units is in wireless communication with an audio source such that each of the audio units receives an audio signal from the audio source. Additionally, each of the audio units has sound emitting capabilities to emit audible sounds from the audio signal toward the user's ear.

A case a portable listening device. The case includes a housing having an interior space to receive the portable listening device; a lid attached to the housing; a rechargeable battery and first and second wireless power receiving elements configured to receive electric charge from a wireless power transmitter during a charging event. The case further includes switching circuitry that is configured to disable one of the first or second wireless power receiving elements during a charging event when the disabled element is receiving power less efficiently than the other element.

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.

The present disclosure provides a HIFI system based on digital connection, which includes an audio outputting device and a HIFI module, the audio outputting device is detachably connected with the HIFI module, when the audio outputting device is connected with the HIFI module, the audio outputting device is electrically connected with the HIFI module, the HIFI module includes a digital analog conversion circuit and a digital interface electrically connected with the digital analog conversion circuit, the digital interface transmits a received digital signal from external to the digital analog conversion circuit to be converted to an analog signal. The present disclosure only need to connect the HIFI module connected with the audio outputting device with the sound source device, and overcomes the problem that user cannot listen to the sound source due to the losing or forgetting to carry the digital analog converter.

A system includes a safety helmet and an earpiece, wherein the earpiece is configured to determine when a user of the earpiece is wearing the safety helmet. The earpiece may include a touch surface and at least one sensor associated with the touch surface and wherein the earpiece is configured to ignore input at the touch surface when the user of the earpiece is wearing the safety helmet. A method includes sensing by an earpiece that a user is wearing a helmet and deactivating sensors associated with a touch input area on the ear piece when the user is wearing the helmet. A method includes charging an earpiece using a battery of a helmet while a user is wearing the earpiece and the helmet. A method includes communicating data from one or more sensors of a helmet or one or more sensors of a motorcycle to an earpiece and providing audio output indicating of the data to a user through a speaker of the earpiece.

Disclosed by the present application are an earphone and a worn detection device thereof. The detection device comprises a sensing panel used for forming a battery encapsulated metal shell, a detection chip connected to an input end and the sensing panel and a control chip connected to an output end of the detection chip; a battery is arranged in an earphone handle of the earphone; the detection chip is used for detecting a sensing signal of the sensing panel and determining a wearing state of the earphone according to the sensing signal; and the control chip is used to adjust the working state of the earphone according to the wearing state. When a user wears the earphone, the earphone handle of the earphone contacts the skin of the user, a capacitance effect is formed between the sensing panel and the skin of the user, and a sensing signal is generated. The detection chip determines the wearing state of the earphone by means of the sensing signal, and the control chip adjusts the working state of the earphone according to the wearing state. The present application reuses the encapsulated metal shell as the sensing panel, which is conducive to the miniaturization of the earphone and the improvement of the sensitivity and reliability of detecting the wearing state.

A system includes a plurality of earpiece sets, each of the earpiece sets comprising a left earpiece and a right earpiece and a smart case. The smart case includes a case housing, a plurality of receptacle sets disposed within the case housing, wherein the receptacle sets are configured to hold the plurality of earpiece sets, a processor disposed within the case housing, and a transceiver disposed within the housing and operatively connected to the processor.
