TECHNICAL FIELD

[0001] The utility model relates to USB camera technical field, concretely relates to USB camera with recording and audio power amplifier. BACKGROUND

[0002] The conventional USB camera mostly uses fixed support or folding support. Due to the limitation of the support structure, the camera only has the image collection function in one direction, and when the multi-directional image collection requirement is needed, the camera operation cannot be well carried out. Therefore, the conventional USB camera has great limitation, and it is difficult to meet the more and more market use demand.

[0003] Through the search, the patent with patent announcement number CN201520036823.X discloses a rotatable high-definition USB camera, although the device can realize the free image and video collection function of multi-angle and nearly 360-degree spherical space by setting the first support and the second support which are connected through the rotating part when using, and the use performance of the USB camera is effectively improved, but when the device is used, the camera cannot be separated from the support, which limits the portability of the equipment. The user cannot use the camera alone without carrying the support, which will bring inconvenience in some occasions that need to be carried lightly or arranged flexibly (such as outdoor shooting, temporary meeting, etc.). And when the camera is not used, due to the fixation of the support, the whole device needs to occupy more storage space. UTILITY MODEL CONTENT

The switch 103 is directly arranged on the microphone module 1, which improves the convenience of user operation, reduces the need for additional search or operation of other equipment, and reduces the risk of misoperation. The microphone module 1, power amplifier module 2 and camera module 3 are controlled by the switch 103 and the power supply, and the user can easily control the power on / off of the microphone module 1, power amplifier module 2 and camera module 3 by simply operating the switch 103, making the device operation more intuitive and convenient without complex settings or adjustments. By controlling the power on / off through the switch 103, the power consumption of the device when not in use is effectively avoided, the energy consumption is reduced, the energy waste is reduced, which meets the modern energy-saving and environmental protection concept. The bottom end of the camera module 3 is provided with a protrusion 301, the protrusion 301 is provided with a clamping groove 302, the fixing frame 4 is provided with a connecting seat 402, the fixing frame 4 is provided with a base 404, the base 404 is rotatably installed with a connecting rod 405, the connecting seat 402 is rotatably installed at one end of the connecting rod 405 away from the base 404.

[0040] Working principle:

[0041] The user controls the power on / off of the camera module 3, power amplifier module 2 and microphone module 1 through the switch 103. The camera module 3 is connected with the computer through the USB data line to establish a data transmission channel. The camera module 3 captures light through its built-in optical lens system (including lens group, automatic focusing system and infrared filter, etc.) and forms an optical image. The lens group adjusts the direction of light and focuses to make the image clear and visible; the automatic focusing system ensures that the image remains clear at different distances. The sensor (such as CMOS or CCD) in the camera module 3 receives the optical image and converts it into an electrical signal. The pixel array on the sensor is composed of numerous light-sensitive units (i.e. pixels), each of which converts the received light into electric charge, and the amount of electric charge is proportional to the intensity of light. The readout circuit converts the electric charge generated by the pixels into a voltage signal and performs amplification and transmission; the control circuit is responsible for transmitting control signals such as exposure time, gain, etc. to the pixel array. The camera module 3 internally contains an image processing chip that processes the image signals captured by the sensor, such as digitization, enhancement, noise reduction, exposure control, etc. The processed digital image signals are transmitted to the computer through the USB data line for further processing or storage.

[0042] When the camera module 3 captures the optical image, the microphone module 1 also captures the sound signal at the same time. After the image and audio signals are processed and amplified, they are transmitted to the computer through the USB data line simultaneously. The microphone module 1 captures the sound signal through the microphone 101 on the cantilever support 102. The microphone 101 converts sound (mechanical wave energy) into an analog audio signal. The analog-to-digital converter in the microphone module 1 converts the analog audio signal into a digital audio signal. The digital audio signal is amplified by the power amplifier module 2 to improve the intensity and clarity of the audio signal. The amplified digital audio signal can be transmitted to the computer for storage or playback through the USB data line.

[0043] The computer receives and processes image signals from the camera module 3 and audio signals from the microphone module 1. The processed image and audio data can be stored in the hard disk or other storage device of the computer for subsequent use or analysis.
