Example Embodiment

[0034] Example one

[0035] The auxiliary device for directional sound pickup of this embodiment, such as figure 1 , 2 As shown, it includes a height adjustment mechanism, a driving mechanism, a transmission mechanism, and an identification mechanism.

[0036] Among them, the height adjustment mechanism includes a fixed part and a movable part. The top of the fixing part is fixed to the roof and extends from the roof to the room. The movable part and the fixed part are the movement pair, and a pan / tilt is installed at the bottom of the movable part. A hanging wheat is fixed under the pan / tilt, and the pan / tilt is driven by the pan / tilt motor and drives the hanging wheat to rotate. In order to meet the needs of the tracking microphone function.

[0037] The driving mechanism drives the transmission mechanism to drive the height adjustment mechanism to realize the level change of the hanging wheat, and the transmission mechanism is used to drive the height adjustment mechanism and i...

Example Embodiment

[0046] Example two

[0047] The difference between this embodiment and the first embodiment is that the transmission mechanism in this embodiment adopts a pneumatic / hydraulic manner, which has achieved the purpose of moving the movable part up and down. Specifically, the movable part uses air / hydraulic way to raise and lower. If the corresponding driving mechanism is pneumatic, it is driven by a pneumatic unit, and if it is hydraulic, it is driven by a hydraulic motor. The other setting methods can be adjusted appropriately according to the first embodiment

Example Embodiment

[0048] Example three

[0049] The difference between this embodiment and the third embodiment is that the ball screw is replaced with a rack and pinion structure, and the others are basically the same or adjusted adaptively.

Abstract

The invention relates to an auxiliary device for directional pickup microphone hanging and a user identity confirmation and tracking method, and belongs to the technical field of directional pickup ofpickup microphones. The auxiliary device for directional pickup microphone hanging comprises a height adjusting mechanism, a driving mechanism, a transmission mechanism and an identity recognition mechanism. The height adjusting mechanism comprises a fixed part and a movable part; a holder is arranged at the bottom end of the movable part; a hanging microphone is fixedly connected with the holder. The lifting of the hanging microphone is realized through the driving mechanism. The identity recognition mechanism comprises an identity information acquisition device, an information comparison database, a recognition judgment module/device and an audio adjustment module/device; the identity information acquisition device is mounted on the outer side of the bottom of the fixed part. Accordingto the invention, equipment simplification is realized through omnibearing sensing and the holder, the use is convenient, the efficiency is improved, and the maintenance is convenient. And the intentional user is separated from the user, and the identity recognition is limited in a use state and a non-use state, so that the practical application of teaching sound amplification is facilitated.

Description

technical field [0001] The invention relates to an automatic lifting microphone and a corresponding identification and judgment method, belonging to the technical field of sound pickup microphones. Background technique [0002] The hanging mic is generally installed at a fixed position on the ceiling. Except for special circumstances (such as in 201822144814.9 "A Teaching Recording and Broadcasting System", the hanging mic can move on the slide rail in a certain way), and the position of the hanging mic generally does not change. [0003] The original intention of applying hanging microphones to teaching sound reinforcement is to free hands for teachers to teach easily and for the sake of teachers' health. [0004] With the application of hanging microphones in teaching sound reinforcement, teachers are more free in the teaching process, but hanging microphones added to the teaching sound reinforcement system for the purpose of freeing hands have become obstacles that limit ...
