Wireless karaoke microphone headset

The invention discloses a wireless karaoke microphone headset which comprises a left microphone, a right microphone, an ADC (analog-to-digital converter), a reverberation effect unit, a sound mixing unit, a DAC (Digital To Analog Converter), a left loudspeaker, a right loudspeaker and a wireless connection unit which are positioned at auricular positions when a user wears the headset. Voice signals picked up by the left and right microphones enter the reverberation effect unit after being subjected to analog-to-digital conversion by the ADC; after carrying out reverberation effect processing on the digital voice signals, the reverberation effect unit sends the digital voice signals to the sound mixing unit; the wireless connection unit receives a music accompaniment signal sent by a mobile terminal and sends the music accompaniment signal to the sound mixing unit; the sound mixing unit mixes the voice signals with the music accompaniment signal and sends a mixed signal to the DAC; after digital-to-analog conversion, sound is output to the user by the left and right loudspeakers; and the headset can send the sound mixed signal, the voice signals or a holographic sound field signal to the mobile terminal in a Bluetooth manner. By the wireless karaoke microphone headset disclosed by the invention, karaoke experience of the user and sharing capacity of high-quality sound an be effectively promoted.

The invention discloses an anti-radiation complementary metal oxide semiconductor (CMOS) device and a preparation method thereof and belongs to the technical field of CMOS integrated circuit. The CMOS device comprises a substrate, a source region, a drain region and a vertical channel located on the substrate. A first medium protective region is added in the vertical channel, the first medium protective region is located in the middle of the vertical channel to separate the vertical channel into two portions, the height of the first medium protective region is equal to the length of the vertical channel, an active silicon platform central axis serves as a center, and the distance between the edge of the first medium protective region and the outside of the channel is 20-100nm. Simultaneously a second medium protective region is arranged below the source region or the drain region on the substrate, the length of the second medium protective region is equal to that of the source region or the drain region, and the height of the second medium protective region is 10-50nm. The medium protective regions are added, a route of the source region and the drain region for collecting charges can be effectively separated, and signal grain characteristics of the device are improved.

Data processing method and device

The invention discloses a processing method and device, and the method comprises: obtaining a to-be-shared video frame under the condition that the connection with at least one second electronic device is built, wherein the to-be-shared video frame at least comprises one piece of identification information; sending the to-be-shared video frame to at least one second electronic device; and determining a display state of the to-be-shared video frame on the second electronic device at least based on an identification result of the identification information fed back by the second electronic device. According to the method and the device, identification information is set in a video frame transmitted to second electronic equipment; an identification result of the identification information fedback by the second electronic equipment is subsequently received to determine a sharing state; if the identification information is identified, the fact that the second electronic equipment normallydisplays the transmitted video frame is determined; and when the identification information cannot be identified, it is determined that the second electronic equipment does not normally display the transmitted video frame, so that the video sharing end side knows the content sharing situation in time, sharing related management and control can be carried out in time, and the content sharing effectcan be improved.

A data processing method and device

The present application discloses a processing method and device. The method includes: in the case of establishing a connection with at least one second electronic device, obtaining a video frame to be shared, the video frame to be shared includes at least one identification information; sending the video frame to be shared To at least one second electronic device; at least based on the recognition result of the identification information fed back by the second electronic device, determine the display status of the video frame to be shared on the second electronic device. The method and device set the identification information in the video frame transmitted to the second electronic device, and then receive the recognition result of the identification information fed back by the second electronic device to determine the sharing status, for example, when the identification information is recognized, it is determined that the second electronic device has Display the transmitted video frame normally, and determine that the second electronic device does not normally display the transmitted video frame when the identification information cannot be recognized, so that the video sharing terminal side can know the content sharing situation in time, which is conducive to timely sharing related management and control, and is conducive to Improve the content sharing effect.
