[0024] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0025] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0026] Example 1

[0027] In this embodiment, a bird voiceprint recognition device is proposed. Figure 1-Figure 5 The bird voiceprint recognition device includes a bracket 1, a solar panel 2 combined with the bracket 1 and exposed to sunlight, and a voiceprint recognition host 3.

[0028] Further explanation, such as Figure 2 As shown, there is a battery assembly 7 in the bracket 1. Specifically, the battery assembly 7 includes a battery pack 71 that is charged by the solar panel 2 and supplies power to the voiceprint recognition host 3, and a battery pack PCB 72 that controls the charging and power supply of the battery pack 71.

[0029] See also Figure 3 The bottom of the voiceprint recognition host 3 is provided with a shield 5, and the bottom of the shield 5 is a bracket extension part 6 extending outward from the bracket 1 and responsible for fixing the entire bird voiceprint recognition mechanism.

[0030] Further explanation, the shield 5 has Figure 4 The accommodating space shown in the figure has an omnidirectional microphone head 8 which coincides with the axis of the voiceprint recognition host 3 , and a plurality of through slots 4 which are arranged on the side wall of the shield 5 to connect the accommodating space with the outside of the shield 5 .

[0031] To further explain, the omnidirectional microphone head 8 does not collect sounds with a threshold value below a certain range, and filters out useless bird sound slice data, thereby improving recognition accuracy.

[0032] The omnidirectional microphone head 8 is centered in the accommodating space and has a through slot 4 as a sound propagation channel, so that the sound pickup quality is improved and the monitoring range is wider.

[0033] This embodiment also adds a cleaning structure at the shield 5, specifically, as Figure 5 As shown, the omnidirectional microphone head 8 is encircled by an arc sleeve 12 (the arc sleeve 12 can be hollowed out), the arc sleeve 12 has a baffle 9 on its edge, and a baffle first extension block 10 arrayed on the side wall of the baffle 9 and extending into the plurality of through slots 4. This design has the following functions:

[0034] ① Such as Figure 4 and Figure 5 As shown, the arc sleeve 12 has an annular accommodating cavity, so that when the arc sleeve 12 slides along the omnidirectional microphone head 8, the attachments located at the periphery of the omnidirectional microphone head 8 fall into the annular cavity through shearing action.

[0035] ② When the arc-shaped sleeve 12 slides along the omnidirectional microphone head 8, the foreign matter in the through groove 4 is pushed down by the first extension block 10 of the baffle plate and falls into the annular accommodation cavity or falls from the outer periphery of the shield 5;

[0036] From ①②, it can be seen that the cleaning structure has a good cleaning effect and can maintain and service the host after improving the sound pickup quality.

[0037] Further explanation: the side wall of the baffle 9 also has a baffle second extension block 11 extending from the through slot 4 and extending relative to the through slot 4. The baffle second extension block 11 is controlled by personnel, that is, during maintenance, the personnel can move the baffle second extension block 11 to control the arc sleeve 12 to slide relative to the omnidirectional microphone head 8.

[0039] The voiceprint recognition host 3 has a sound pickup (analysis) circuit board and a power board connected to the battery pack 71. The sound pickup (analysis) circuit board is connected to the omnidirectional microphone head 8. As described above, the omnidirectional microphone head 8 does not collect sounds with a threshold value below a certain range, filters out useless bird sound slice data, and supports wireless transmission.
