The electronic device simultaneously maintains the first Bluetooth connection and the second Bluetooth connection.

A method for audio modification for a wearable device in operative Bluetooth communication with a device includes receiving a sound signal at a microphone of the wearable device, encoding the sound signal at a digital signal processor of the wearable device using a codec to provide an encoded audio stream, routing the encoded audio stream from the digital signal processor over a Bluetooth parallel simultaneous transport channel to the device, modifying the encoded audio stream using an audio modification software application executing at a processor external to the wearable device to provide an encoded modified audio stream, communicating the encoded modified audio stream from the audio modification software application executing on the processor over the Bluetooth parallel simultaneous transport channel back to the wearable device, and communicating the encoded modified audio stream from the wearable device over a Bluetooth hands free profile (HFP) channel to the device.

An electronic device according to various embodiments includes: a memory, a communication module comprising communication circuitry configured to communicate with an external electronic device, and a processor operatively connected to the memory and the communication module, wherein the processor is configured to: confirm that the external electronic device is in a worn state through the communication module, and transmit a control command through the communication module to change an audio output mode of the external electronic device based on an operating state of the electronic device being changed according to an instruction stored in the memory so that a designated condition is satisfied, to thereby control the operation of the external electronic device according to the designated condition.

A Bluetooth communication system is provided, which comprises a Bluetooth host device and a Bluetooth device set. The connections between the Bluetooth host device and the Bluetooth device set complies with the specification of Bluetooth Low Energy Audio technology. The Bluetooth device set comprises at least a first member device and a second member device. The first member device and the second member device may be configured in a first mode wherein uplink audio signal transmission is allowed, and the connections are carried out by isochronous streaming channels respectively. The first member device transmits captured voice data to the Bluetooth host device, while the second member device does not transmit. When an event is triggered, the first member device can notify the second member device through a third-part device, so that the first member device and the second member device can carry out subsequent voice input handover procedures.

A method of preventing loss of headphones configured to communicate with a cell phone enables an alarm setting using an app on the cell phone; the app responding by continuously measuring a received magnitude of a wireless signal transmitted between the cell phone and the headphones. If the measured received magnitude is lower than a predetermined threshold value for a first predetermined time, an audible alarm is activated at the headphones. The continuous measurement and the activation of the alarm dependent on the measured received magnitude occur automatically, independent of any user interaction with the app after the alarm setting enablement. Another method addresses a corresponding issue in a similar way to prevent loss of one earbud of a pair.

The present invention relates to a smartphone having an earphone storage unit including: at least one an earphone storage unit formed in a cylindrical shape; and an earphone withdrawing unit for facilitating the withdrawal of an earphone stored in the earphone storage unit, wherein the earphone withdrawing unit includes: a cylinder; a shaft reciprocating in the cylinder; a knock member rotating in response to the shaft whenever the shaft is pressed; and an elastic member pushing the knock member outward in response to the knock member. The cylinder has guide grooves and guide protrusions formed inside the cylinder in a longitudinal direction. The shaft has a moving protrusion moving along the guide groove in response to the guide groove, and sawteeth rotating the knock member in response to the knock member, and is formed to reciprocate in the cylinder.

In order to withdraw the earphone stored in the earphone storage unit, when a user presses the earphone in an earphone insertion direction to a predetermined depth and releases the earphone, the shaft of the earphone withdrawing unit is pushed out so that the earphone is discharged.

A peripheral device for use with a user terminal, the peripheral device comprising: a non-graphical actuator operable to be actuated by a user; an interface for connecting to the user terminal; and control logic for interfacing with the user terminal in order to control a communication client application running on the user terminal, and to thereby control a voice or video call that is conducted over a packet-based network from the user terminal using the communication client application. The control logic is configured such that the control of the call comprises performing a function in relation to the call in response to actuation of said hardware actuator by the user, and furthermore that the function of the actuation of the actuator is dependent on a current status of the call.

An audio rendering device includes: at least one wireless communications interface configured to receive a first plurality of audio packets from a wireless communication device, the first plurality of audio packets including frames of audio data for a first audio channel from a set of one or more audio channels; and a processing unit; wherein the audio rendering device is configured to release, at respective first buffer release times, the frames of the audio data for the first audio channel from a first buffer for rendering by the processing unit; wherein the audio rendering device is configured to receive one or more messages from an other audio rendering device; and wherein the audio rendering device is configured to synchronize the first buffer release times with second buffer release times associated with the other audio rendering device based on the received one or more messages.

A system and method for a face mask communication system. The face mask communication system includes a removable microphone that can be installed in a face mask to allow the wearer to clearly and privately communicate with another user over a Bluetooth enabled mobile device such as a cell phone. In illustrated examples, a microphone unit is deformable to enable the microphone unit to form a custom fit over the nose bridge to seal the mask on the user's face. The face mask communication system includes an application program operating on the mobile device that allows a user to initiate and secure private conversations with other users.

One example discloses an apparatus for near-field magnetic induction (NFMI) based robustness, including: a first wireless device including a first wireless signal interface and a first NFMI signal interface; wherein the first wireless signal interface is configured to receive a data set from a third wireless device; wherein the first NFMI signal interface is configured to communicate with a second wireless device through a second NFMI signal interface; and wherein the first wireless device is configured to detect an error in the data set received from the third wireless device and in response to detecting the error configure the first NFMI signal interface to receive the data set from the second wireless device through the second NFMI signal interface.
