A device has a standard female audio connector that is capable of receiving four-pole male connectors and three-pole male connectors and implements: means (CTRL, VCC, S1) for selectively transmitting a DC power supply signal via a first pin (DP1) of said connector; means (CTRL, ANC) for selectively activating a cancellation mechanism for ambient noise from digital audio signals that are intended to be received, via the first pin, in a manner superimposed on said DC power supply signal; means (CTRL, MIF) for selectively transmitting via a second pin of said connector, in a manner superimposed on said audio signals, a timing clock that is intended for digital microphones (DML, DMR) or other sensors; means (CTRL) for configuring itself vis-à-vis the DC power supply signal, the ambient noise cancellation mechanism and the timing clock, according to a determined type of listening device that is effectively connected via said connector.

A mobile terminal and a mobile terminal audio signal processing system including the same are disclosed. The mobile terminal includes a first body including an opening, a main circuit board, and a main earphone jack, a first audio signal processing body including a first circuit board, on which a sub-sound module receiving a digital audio signal from the first body and converting the digital audio signal into an analog audio signal is mounted, and a sub-earphone jack outputting the analog audio signal, and a controller outputting a first audio signal to the sub-earphone jack and outputting a second audio signal to the main earphone jack. The first audio signal processing body is a first state where the first audio signal processing body is coupled with the opening, or a second state where the first audio signal processing body is separated from the first body.

A headphone includes a pair of right and left headphone units, a resilient band formed substantially into a U shape to be mounted on a human head, and a pair of arm members. The device has a padded Lycra like band with Bluetooth infused speakers that are placed around the crown of the head and over the ears. The headphone device will stay in place at all times and eliminates possible slippage.

According to an embodiment of the disclosure, disclosed is an electronic device that includes a first connector electrically connectable to an external electronic device, a second connector electrically connectable to an external audio plug, a wireless communication circuit, and at least one processor. When the electronic device is connected to the external electronic device through the first connector, the at least one processor may receive a first digital audio signal from the external electronic device through the first connector, convert the received first digital audio signal into a first analog audio signal, and output the converted first analog audio signal through the second connector. When the electronic device is connected to the external electronic device through the wireless communication circuit, the at least one processor may receive a second digital audio signal from the external electronic device through the wireless communication circuit, convert the received second digital audio signal into a second analog audio signal having a sound quality lower than that of the first analog audio signal, and output the converted second analog audio signal through the second connector.

A multifunctional microphone, includes a controlling mainboard; a sound collector electrically connected with the controlling mainboard; a speaker electrically connected with the controlling mainboard; and a sound adjusting module arranged on the controlling mainboard and configured to adjust sound collected by the sound collector.

A user device determines whether a device connected to its headset jack is an audio accessory device. If the device connected to the headset jack is an audio accessory, the user device connects one or more pins of the headset jack to an audio codec. If the device plugged into the headset jack is not an audio accessory device, the user device connects one or more pins of the headset jack to alternate circuitry. The user device then determines, through the alternate circuitry, an electrical operating parameter requirement of the accessory device, and provides, from the alternate circuitry, the required operating parameter to the accessory device through the headset jack. The alternate circuitry may include an adjustable voltage regulator and/or an adjustable current regulator and the required operating parameter may be one or more of a voltage supply and a current supply.

Embodiments are provided for components configured for audio playback. According to certain aspects, a transducer includes dual voice coils disposed in a magnet section, whereby the magnet section generates an electromagnetic field that causes the dual voice coils to actuate in response to an applied audio signal. The transducer further includes a diaphragm coupled to the dual voice coils that actuates according to the dual voice coils and produces audio output. In some implementations, the transducer may be disposed within a cutout area of an electronic device, whereby the transducer is secured to the electronic device via a roll-surround suspension.

In a speech-based system, a wake word or other trigger expression is used to preface user speech that is intended as a command. The system receives multiple directional audio signals, each of which emphasizes sound from a different direction. The signals are monitored and analyzed to detect the directions of interfering audio sources such as televisions or other types of electronic audio players. One of the directional signals having the strongest presence of speech is selected to be monitored for the trigger expression. If the directional signal corresponds to the direction of an interfering audio source, a more strict standard is used to detect the trigger expression. In addition, the directional audio signal having the second strongest presence of speech may also be monitored to detect the trigger expression.

An audio processing device and an audio processing method are provided. The audio processing device includes a first controller configured to initialize the audio processing device; and a second controller configured to connect the audio processing device and an audio output device while the first controller initializes the audio processing device, and to transmit a message reporting completion of the connection of the audio processing device and the audio output device to the first controller, wherein the first controller is configured to start an operation of outputting audio to the audio output device in response to the message reporting the completion of the connection from the second controller.

Provided is a speaker simulating a rock comprising: a) a housing simulating a rock, the housing having a plurality of openings; b) a loudspeaker placed inside of the housing, audio from the loudspeaker leaving the housing through the openings; c) a solar panel attached to the housing in a configuration that allows light from outside of the housing to contact the solar panel to generate electricity; d) a rechargeable battery to be charged by the electricity from the solar panel, the rechargeable battery powering the loudspeaker; e) a wireless processor configured to communicate with a wireless protocol to obtain audio content; wherein the speaker plays the audio content received from the wireless communication through the loudspeaker.
