The utility model discloses a capacitance microphone, which comprises a mounting seat, a mounting frame is hinged to the top of the mounting seat, a microphone is arranged on the inner side of the mounting frame, a plurality of mounting buckles are arranged on the inner side of the mounting frame, and a plurality of mounting buckles corresponding to the mounting buckles are arranged on the outer side of the microphone. The installation buckle is connected with the installation buckle through an elastic component, the elastic component is an elastic line or an elastic rope, the top of the installation base is hinged to the installation frame through a hinge screw, and the hinge screw is in threaded connection with a manual adjusting screw. The microphone is convenient to mount, when vibration is generated outside, the vibration is transmitted to the elastic component through the mounting seat and the mounting frame, and the vibration is retarded by the elastic component and then transmitted to the microphone due to the elasticity of the elastic component, so that the influence of the external vibration on the microphone is greatly reduced, and the service life of the microphone is prolonged. The microphone is ensured not to influence audio receiving signals due to vibration, and the microphone is ensured to output clear sound.

This utility model relates to the field of pet equipment technology, specifically to a pet activity monitoring collar with a removable battery. Under normal circumstances, when the accelerometer detects that the collar is stationary and has been placed there for 10 minutes, the accelerometer will promptly transmit this detected state signal to the main control MCU. Upon receiving the signal, the main control MCU will immediately enter sleep mode, thereby reducing energy consumption and achieving energy saving. However, once the accelerometer senses that the collar has moved, it will immediately receive this dynamic change signal and quickly transmit the signal to the main control MCU, thereby controlling the main control MCU to start from sleep mode. After the main control MCU is awakened, it will activate the audio IC through its control function. When the audio IC is activated, it will output an analog signal to the speaker device, ultimately enabling the stored voice commands to be played clearly and accurately for further operation or command transmission.

A key device of a membrane keyboard comprises a lower cover, a supporting plate, an elastic piece, a membrane circuit piece, an elastic body, an upper cover and a key cap. The lower cover comprises a lower substrate and a lower convex cover. And the supporting plate and the lower convex cover jointly define a sound effect enhancing space. And the elastic sheet is located in the sound effect enhancing space. The key cap abuts against the elastic body and comprises a cap cover, a plunger connected with the cap cover and two supporting feet extending downwards from the plunger. The supporting legs extend into the sound effect enhancing space, and one of the supporting legs abuts against the elastic sheet. When the key cap is pressed, one of the supporting feet abuts against the elastic piece to enable the elastic piece to deform and accumulate elastic force, and when the key cap is loosened, the elastic piece pushes the key cap to move upwards, and the elastic piece releases the elastic force and impacts one of the supporting feet to make a sound.
