An electronic device includes: a power management module; a connector; a device recognition circuit; and a processor. The processor is configured to: based on a first resistance value detected in a first recognition pin, control the power management module to supply a first power signal to a first power pin and to supply a second power signal to a second recognition pin; receive first identification information of an external device via the first recognition pin or the first data pin; and based on the first identification information, control the power management module to cut off a supply of a first power signal and to maintain a supply of the second power signal.

A detachable headband for a headphone system can incorporate a headband identification circuit that stores or encodes a headband identification parameter value. When the headband becomes attached to an ear cup, the headband can transmit the headband identification parameter value to the ear cup.

A three-dimensional virtual reality vest; the three-dimensional virtual reality vest may be beneficial for use by a user to enhance virtual reality, video game, movie, or other media experiences. The three-dimensional virtual reality vest includes a vest garment having a surround sound speaker system, a series of embedded haptic feedback devices, and additional features configured to provide an immersive three-dimensional user-experience for a user when worn.

A low-profile earbud is disclosed that sits securely within an ear of a user. The earbud includes a protruding portion that passes through a channel defined by the tragus and anti-tragus of the ear. In some embodiments, the protruding portion can take the form of a cable configured to supply power and transfer data to the earbud. In some embodiments, the protruding portion can provide additional space for electrical components and sensors supporting the earbud.

The present invention relates to a kit comprising a microphone and a headphone, and also a case member provided with a first cut-out region for accommodating the microphone and a second cut-out region for accommodating the headphone as well as electronics means for charging the microphone and/or the headphone; the microphone comprising: a sound-receiving portion; a headphone connecting portion; an extension portion connecting a distal end arranged to connect to the sound-receiving portion and a proximal end opposite the distal end thereof and arranged to connect to the headphone connecting portion, the proximal end extending a distance from the distal end such that a voice signal received is greater than the environmental noise thus yielding a higher signal to noise ratio; the headphone comprising: a main body portion dimensioned for adapting to the user's ear contour to retain the headphone on the ear; a microphone connecting portion provided on the main body portion; each of the headphone connecting portion and the microphone connecting portion is provided with magnets, when the microphone is in use, the microphone is arranged to detachably connect to the headphone by means of their respective the magnets. The kit of the present invention allows the use of a boom microphone in a portable headphone.

Various aspects include wearable audio devices enabling modular component attachment and detachment. In certain implementations, a wearable audio device includes: a headband for contacting a head of a user; an earpiece coupled with the headband for positioning proximate an ear of the user, the earpiece having an electro-acoustic transducer configured to output audio signals; and a slot configured to engage an electronic component, where the slot includes one or more snap-fit and/or friction-fit connectors for selectively engaging the electronic component.

Various implementations include portable loudspeakers. Certain implementations include a portable loudspeaker that mitigates ingress of moisture, particulates, and other contaminates. In particular implementations, the portable loudspeaker includes a housing with an enclosure having a co-molded construction for ingress resistance.

A Bluetooth device controlling a plurality of wireless audio devices, includes: a wireless communication circuit, to receive a wireless audio device identifier from each wireless audio device; a sound processing circuit to apply independent audio effects on a main audio stream such that the sound processing circuit outputs as many modified audio streams as the wireless communication circuit has received identifiers of wireless audio devices, on the basis of the characteristics of each wireless audio device; an allocation circuit to allocate each modified audio stream to a respective wireless audio device; and a transmission circuit to wirelessly transmit through a Bluetooth usage each modified audio stream to the respective wireless audio device for emission by the wireless audio devices.

A portable audio input/output device may include one or more openings that extend through a cover of the device and allow acoustic signals outside a housing of the device to reach a microphone disposed within the housing. The opening(s) may be illuminated by a light guide disposed within the housing, which scatters light emitted from lights disposed within the housing. In some instances, a hole may pass through a printed circuit board to allow acoustic signals to be received by the microphone disposed below the printed circuit board. An input/output (I/O) interface module with multiple buttons and inputs may be installed in the hole. The multiple buttons and I/O ports of the I/O interface module may be aligned along an axis vertical relative to the housing and centered with respect to each other.

An audio processing apparatus includes a first input port, a second input port, a first processor that processes an audio signal input to the first input port and that includes a first adjuster which adjusts acoustic characteristics of the audio signal, a second processor that processes an audio signal input to the second input port, and output ports having a first particular output port. In a first operation mode, the first adjuster is set in an effective state and each of an audio signal as processed by the first processor and an audio signal as processed by the second processor is output from one or more of the output ports. In a second operation mode, the first adjuster is set in an ineffective state and an audio signal as processed by the first processor is output from the first particular output port.
