Problems solved by technology

[0002] General gooseneck microphones are used in the meeting room, and because of the short pick-up distance of the gooseneck microphone, the speaker is in a posture close to the microphone for a long time during the meeting, which will cause physical discomfort to the participants, and if the speech When the speaking posture of the speaker changes, the sound pickup effect of the gooseneck microphone will decrease, and even cause the voice to fluctuate.

Embodiment 1

[0033] Such as figure 1 and figure 2 As shown, this example provides a conference system based on an array microphone, including: an array microphone 1, a switch control circuit 2, a loudspeaker 3 and a wireless controller 4, and the switch control circuit 2 and the loudspeaker 3 are respectively connected to The array microphone 1 is connected, and the array microphone 1 is two or more microphones arranged successively on the conference table; the switch control circuit 2 includes a wireless receiving module; the wireless controller 4 includes an MCU single-chip microcomputer, a first pickup, The second pickup and wireless transmitting module, described wireless controller 4 is connected with the wireless receiving module of switch control circuit 2 by wireless transmitting module, described first pickup and the second pickup are connected with MCU single-chip microcomputer respectively, described first The pickup is used to pick up the sound size of the wireless controller...

Embodiment 2

[0041] On the basis of Embodiment 1, after the switch control circuit 2 described in this example receives the sound size and the comparison result, it adjusts the opening number of the microphone in real time until the opening number of the microphone can make the sound size picked up by the first sound picker match the setting. If the fixed value matches, then keep the open number of the microphone unchanged. Preferably, if the difference between the magnitude of the sound picked up by the first sound pickup and the set value does not exceed 5db, it is determined to be consistent.

[0042] Because the speaker's posture will constantly change when he is speaking, and the volume of the speech will also fluctuate according to his emotions. Therefore, it is normal and necessary for the volume of the sound picked up by the first pickup to fluctuate to a certain extent; therefore, The difference between the magnitude of the sound picked up by the first sound pickup and the set val...

Embodiment 3

[0046] Such as image 3 As shown, the further improvement of this example is that a distance sensor 5 is also included, and the distance sensor 5 is arranged on the conference table directly in front of each participant, and the distance sensor 5 is used to detect the wireless controller 4 and the array microphone 1 The MCU single-chip microcomputer transmits the distance data detected by the distance sensor 5 to the switch control circuit 2 through the wireless transmitting module, and then controls the first opening quantity of the microphone through the preset distance parameter.

[0047] The MCU single-chip microcomputer is used as an operation controller, and the distance sensor 5 can detect the shortest distance between the participants and the array microphone 1 on the conference table. The detection method is to place a distance sensor 5 in the corresponding microphone area directly in front of each participant. That is to say, the distance sensor 5 is set on the confe...

Abstract

The invention provides a meeting system based on array type microphones. The meeting system based on the array type microphones comprises the array type microphones, a switch control circuit, a loudspeaker and a wireless controller, wherein the switch control circuit and the loudspeaker are connected with the array type microphones; the array type microphones are more than two microphones arranged on a meeting table in sequence; the wireless controller comprises an MCU single-chip microcomputer, a first pickup, a second pickup and a wireless emitting module; the wireless controller is connected with the switch control circuit; the wireless controller judges whether a participant makes a statement or not through the second pickup until one participant makes a statement, and the volume of voice heard by the spokesman can be detected through the first pickup; the MCU single-chip microcomputer compares the volume of the voice with a set numerical value and sends the result to the switch control circuit. The meeting system based on the array type microphones achieves the pickup effect, the spokesman can make a statement easily, the voice is prevented from being too large or too small suddenly, and meanwhile the quality of output voice is ensured.

Description

technical field [0001] The present invention relates to a conference system, in particular to a conference system based on an array microphone. Background technique [0002] General gooseneck microphones are used in the meeting room, and because of the short pick-up distance of the gooseneck microphone, the speaker is in a posture close to the microphone for a long time during the meeting, which will cause physical discomfort to the participants, and if the speech When the speaker's speaking posture changes, the sound pickup effect of the gooseneck microphone will decrease, and even cause the voice to fluctuate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a conference system based on an array microphone that does not limit the speaker's posture, ensures the quality of the output sound, and avoids loud and small sounds. [0004] In this regard, the present invention provides a conference system based on an ar...
