There is disclosed an audio recorder that automatically determines, when preset microphones are configured to be detachable and different microphones are attached to the same jacks, whether or not the different microphones are in-house microphones, and automatically determines which of the X-Y technique or the A-B technique is used as the attachment technique. Holders in the audio recorder include a switch structure in which, in cases where the different microphones are attached in place of the preset microphones, a contact is turned on only when the different microphones are in-house microphones. Further, a main body unit includes a processor that, when the contact in the switch structure is turned on, automatically determines which of the X-Y technique or the A-B technique is used based on a voltage value of a certain terminal in a plug of the different microphones.

Embodiments of an electronic device are disclosed. The electronic device may include a USB Type-C connector including at least one configuration channel (CC) pin and a processor operatively connected to the USB Type-C connector. The processor may be configured to: obtain first information of a connected audio output device by using a USB driver; transmit the first information and/or audio card information of the audio output device to an audio framework through a USB framework; control the audio framework to access an interface corresponding to the audio card information; and activate, when at least a portion of second information of the audio output device is obtained through the USB driver while accessing the interface, the interface by transmitting the at least a portion of the second information to the audio framework through the USB framework. Various additional embodiments in addition to the disclosed embodiments are possible.

An intermediary device and a wearable bridge are provided. The wearable bridge is detachably assembled with two wireless earbuds, and includes a headband, two ear cups respectively connected to two opposite ends of the headband, and a wireless module. Each ear cup includes an assembling slot and an electrical connector that is arranged in the assembling slot. Each assembling slot can be assembled with one of the two wireless earbuds so as to enable the corresponding electrical connector to be structurally and electrically connected to the one of the two wireless earbuds. The wireless module is electrically coupled to the electrical connector of each of the two ear cups, and the wireless module is configured to transmit sound signals from an external apparatus to the electrical connectors of the two ear cups, so that the two wireless earbuds are allowed to synchronously play.

Microphone capsules for condenser or electret microphones often exhibit individual deviations from a desired ideal behavior, e.g. the frequency response and phase response. Particularly if a plurality of microphone capsules are interconnected to form a microphone array, suitable microphone capsules must be found in a selection process. Some of these deviations can be corrected electronically, e.g. by filtering with a corresponding filter that is individually adapted. An improved microphone capsule, with which an automatic selection and automatic assembly of circuit boards with microphone capsules is facilitated, comprises an electrostatic sound transducer, an amplifier element that outputs an amplified output signal of the electrostatic sound transducer, and at least one electronic memory element. Data obtained by a measurement and relating to the individual frequency response or phase response of the respective microphone capsule can be stored therein. The data can be read out during manufacturing and during operation, which enables automatic sorting of the capsules during production and automatic calibration of the target circuit in operation.

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 examples of the present invention relate to an apparatus and a method for removing noise from a reception signal and a transmission signal. A method for operating a sound system for removing noise from a reception signal and a transmission signal, according to an example of the present invention comprises the steps of: receiving power through a first path from another electronic device; receiving a plurality of signals including transmission signals from a plurality of microphones; generating first data by multiplexing the plurality of received signals on the basis of the received power; and transmitting, through the first path, the generated first data to the other device. In addition, other various examples are possible.
