Abstract: A wireless transmitting/receiving device includes a wireless emitter, a connector, a digital signal processor, an audio signal connector and an analog signal processor. The wireless transmitting/receiving device is used to be electrically connected to an electronic device and transmit data by sending and receiving wireless signals. The connector is used to be electrically connected to the electronic device. The digital signal processor is electrically connected to the wireless emitter, and the digital signal processor may be connected to the connector. The audio signal connector is used to be electrically connected to the electronic device. The analog signal processor is electrically connected to the wireless emitter, and the analog signal processor may be connected to the audio signal connector.

Abstract: An embedded seat slot structure is disposed at a device having an opening. The embedded seat slot structure includes a cover, an interlocking portion, and a base. The cover covers the opening. The interlocking portion is pivotally connected with the device via a first pivot. An end of the interlocking portion close to the first pivot is connected with the cover. The base is pivotally connected with the device via a second pivot. An end of the base far away from the second pivot is close to the interlocking portion. The base has a connector facing the opening. When the cover is opened, the interlocking portion is driven to rotate, an end far away from the first pivot pushes the base, and then the base is rotated to make the connector exposed at the opening.

Abstract: A communication device includes a body and a sound receiving device. One end of the sound receiving device is pivotally connected to the body. The sound receiving device includes an omni-directional microphone and a uni-directional microphone. A processor has two modes for starting and operating the omni-directional microphone and the unidirectional microphone, respectively. An angle detecting element is located at the body to measure a rotary angle of the sound receiving device relative to the body, and then the processor switches to one of the two modes according to the rotary angle further to start the omni-directional microphone or the unidirectional microphone.
