Embodiment 1
[0033] Such as Figure 1-Figure 6As shown, an energy-saving sound collection device with an automatic activation function includes a waterproof casing 1, a sound sensor 5, a pickup head 6, a sound processor 10, and a control module 14, and the waterproof casing 1 is provided on the long end side wall There is an electronic display screen 3, a control button 2 is arranged below the electronic display screen 3, a solar panel 4 is arranged on the top of the waterproof casing 1, a pickup 6 is arranged on the side wall of the short end of the waterproof casing 1, and a pickup 6 is arranged on the side wall of the waterproof casing 1. The side is provided with a dustproof cover 12, the pickup head 6 is provided with a pickup 13 inside, the pickup head 6 is surrounded by a sound sensor 5, and the sound sensor 5 is provided with a sensitive bracket 21 inside, and the sensitive bracket 21 is used to install the laser emission 22, the sensitive bracket 21 is provided with a laser emitte...
Embodiment 2
[0035] The difference between this embodiment and Embodiment 1 is: in this embodiment,
[0036] The quantity of sound sensor 5 has 4, is distributed around pickup head 6.
[0037] Specifically, such setting helps to improve the sound detection accuracy of the device, and ensures instant and accurate sound collection.
[0038] The working principle of the present invention is: when the device is performing sound collection operation, the device can be installed at a designated position through the side wall mounting bracket 11 first, and then the related program of the device operation can be set through the control button 2, and the sound sensor 5 will perform For the sound detection of the surrounding environment, the laser transmitter 22 inside the sound sensor 5 will send the laser to the reflective diaphragm 23 in real time. When the surrounding environment of the device is stable, the laser passes through the center of the reflective diaphragm 23. When the external sound ...
