Abstract: An electronic device may be configured to: make a call connection to a first external device; identify a first token including information related to the call connection to the first external device; transmit the first token using a communication circuit; receive a second token; based on the second token, identify information related to a call connection to an external device which transmitted the second token; based on the information related to the call connection, included in the second token, corresponding to the information related to the call connection to the first external device or information of the electronic device, identify that the external device having transmitted the second token is the first external device; identify distance information and/or angle information between the first external device and the electronic device using the communication circuit; and based on the distance information or the angle information, control an anti-howler for the call connection.

Abstract: An electronic device including a plurality of microphones and a processor is provided. The electronic device includes a plurality of microphones disposed at different positions in the electronic device, a processor configured to collect input signals input to each of the microphones, acquire direction of arrival (DOA) information corresponding to each of the microphones from the input signals, calculate generation directions of the input signals using the DOA information, adjust a weight of an input signal for each of the microphones, based on the generation directions of the input signals, and generate an output signal for each of the microphones by reflecting the weight adjusted for each of the microphones, and a speaker configured to output an output signal for each of the microphones.

Abstract: An electronic device includes a communication module and a processor operatively connected to the communication module. The processor is configured to: receive and store a first speech voice related to at least a first external device, and a second speech voice related to a second external device; if individual speech is detected, transmit the first speech voice or the second speech voice having a first playback speed to at least a first external device and a second external device; and, if simultaneous speech is detected, convert, into a second playback speed different from the first playback speed, at least a part of a synthesized voice in which at least first overlap speech of the first speech voice and at least second overlap speech of the second speech voice are successively connected, and transmit the synthesized voice to the at least first external device and the second external device.

Abstract: The present invention relates to a humidity-sensing structural color emitting laminate and a structural color display device self-powered by triboelectricity including the same, and more specifically to a structural color display device self-powered by triboelectricity, which can directly sense humidity among human body signals and display the same in structural color immediately without a separate power source and without data processing, and a humidity-sensing structural color emitting laminate for implementing the same.
