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.

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 is driven by the driving mechanism.
[0038] Identity recognition agency, including identity information acquisition device, database for information comparison, module/device for recognition and judgment, module/device for audio adjustment;
[0039] The identity information acquisition device is installed on the outside of the bottom of the fixed part and is used to identify the identity information of the person in the designated identification area.
[0040] In this embodiment, the transmission mechanism adopts a ball screw method. Specifically, it is a ball screw structure installed inside the fixed part and the movable part, and the movable part can move up and down through the ball screw. The corresponding driving mechanism includes a servo motor or a stepping motor for driving a ball screw, and is controlled by a program/device for identification and judgment. Hanging wheat, pan/tilt motors, and servo motors are routed from the inside of the height adjustment mechanism and connected to the indoor power grid.
[0041] In this embodiment, the designated identification area is simultaneously covered by the identification area of ​​the identity information acquisition device and the sound pickup area of ​​the hanging microphone.
[0042] The clothing device for the directional hanging wheat of this embodiment further includes an omnidirectional sensor, and the suspending wheat and the identity information acquiring device can turn to the area pointed by the omnidirectional sensor when the omnidirectional sensor senses the signal. The full-amplification sensor is generally composed of a set of sensors, such as infrared sensors, temperature sensors, etc., not to mention one by one, the purpose is to realize at least 360° sensing function, and in special cases, it will be realized by a single device.
[0043] The information comparison database of this embodiment is used to store the identity and/or temporary identity information obtained by the identity information obtaining device and the identity and/or temporary identity information used by the module/device for identification judgment.
[0044] The identification and judgment module/device is used to compare the identity and/or temporary identity information acquired by the identity information acquisition device with the identity and/or temporary identity information in the information comparison database.
[0045] The audio adjustment module/device, based on the result determined by the recognition and judgment module/device, the audio adjustment module/device calls related parameters or is configured in accordance with the related parameters. So as to adapt to the voice characteristics of people in the recognition area, and adjust the sound reinforcement effect.

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.
