Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
Example one
The invention provides a large conference sound receiving system, which comprises a main controller, a plurality of microphones and a plurality of positioning modules, as shown in figures 1-2. Wherein, a plurality of microphones, a plurality of orientation module all distribute and install in the meeting room. And the microphone is used for receiving the speech of the speaker. And the positioning module is arranged at the position of the speaker and used for positioning the position of the speaker. For example, the positioning module is mounted on the armrest of each table or chair in the room of the conference room, so as to be convenient for the speaker to operate. As shown in fig. 1, the microphones include a first microphone, a second microphone, a third microphone, and a fourth microphone. The positioning module comprises a first positioning module, a second positioning module and a third positioning module. Each microphone and each positioning module are electrically connected with the main controller and perform data interaction with the main controller.
Preferably, the microphone and the positioning module are electrically connected with the main controller respectively. The main controller realizes the positioning of the speaker position by receiving the positioning signal sent by the positioning module, then starts the microphone closest to the speaker in the conference room to receive the voice of the speaker, and receives the voice data sent by the microphone in real time, thereby realizing the function of voice reception of the speaker in the conference room.
The invention arranges a plurality of microphones, and the microphones are distributed and installed in the room of the conference room and are respectively used for detecting and receiving the sound data in the corresponding range. The distribution positions of the microphones can be determined according to the maximum sound receiving distance of the microphones. Each microphone is responsible for detecting and receiving sound data within a corresponding range.
Further, each location module is used for locating the position of a speaker. When a certain speaker needs to speak, the main controller obtains the position of the speaker by receiving a positioning signal of one positioning module, and then obtains a microphone closest to the speaker according to the position matching of the speaker.
Therefore, the main controller starts the microphone closest to the speaker and receives the sound data sent by the microphone in real time, and the speaking and the sound receiving of the speaker are realized. The microphones are distributed and installed in the conference room, so that a host does not need to transmit the microphones to the corresponding speakers, the time for transmitting the microphones is greatly shortened, and meanwhile, the operation of the microphone transmission system is automatically controlled by the main controller to start the microphones, and the microphone transmission system is simple to operate.
Preferably, the present embodiment further comprises a microphone rail. The microphone slide rails can be one or more, and are determined according to the size of a room in a conference room and the sound receiving range of the microphone.
The microphone slide rail is arranged in a room of a conference room and is away from the ground by a first preset distance. For example, the microphone slide rail is installed at the top of the conference hall at a first preset distance from the ground. Wherein, the first preset distance is determined by the maximum sound receiving range of the microphone, a chair made by a speaker and the like. For example, if the maximum sound receiving range of the microphone is 2 meters, the first preset distance may be set to 2 meters, so as to ensure that the microphone above can receive the speaking voice of the speaker. Because the microphone is positioned above the speaker, normal sound reception can be realized as long as the distance between the speaker and the microphone is ensured to be less than or equal to 2 meters.
As shown in fig. 2, the microphones are distributed at different positions of the microphone rail. Preferably, adjacent microphones on the same microphone slide rail are spaced by a second preset distance. The distance between different microphone slide rails is a third preset distance. Similarly, the second preset distance and the third preset distance are both determined by the sound receiving range of the microphone. For example, the distance between adjacent microphones on the same microphone rail is 10 meters.
Preferably, the microphone of the present embodiment is an omnidirectional microphone.
Preferably, the positioning module is a positioning button. The location button is installed in speaker's position department, and every location button all with main control unit electric connection. Each positioning button is provided with a unique code. The main controller stores the corresponding relation between the code of each positioning button and the installation position of the positioning button and the installation position of each microphone in advance.
When the speaker needs to speak, the speaker presses the positioning button, and the main controller receives a positioning signal of the positioning button at the moment. The positioning signal includes a code for positioning the button. Therefore, the main controller can identify the installation position of the positioning button, namely the position of the speaker according to the code in the positioning signal, and further the main controller can identify the microphone closest to the speaker according to the position of the speaker, control the work of the microphone and receive the sound data in real time.
Preferably, the present invention also provides for repositioning of the positioning buttons, i.e. repositioning of the speaker's position by repositioning each positioning button after a change in the table/chair arrangement in the conference room.
Further, this embodiment further includes: the sound wave generator, first sound wave receiver and second sound wave receiver. The first sound wave receiver and the second sound wave receiver are arranged at two corners of one side surface of the room of the conference room, and the distance between the first sound wave receiver and the second sound wave receiver is known. The sound wave generator is arranged at the position of the positioning button.
When the arrangement in the room of the conference room is changed, the sound wave generator is arranged at the position of each positioning button, and the positioning buttons are repositioned by sending out sound wave signals.
Preferably, the sound wave generator, the first sound wave receiver and the second sound wave receiver are respectively connected with the main controller.
When the positioning button needs to be repositioned, the sound wave generator arranged at the position of the positioning button sends out a sound wave signal, and meanwhile, the time of sending out the sound wave signal is recorded and uploaded to the main controller.
The first sound wave receiver and the second sound wave receiver receive the sound wave signals and respectively record the time of receiving the sound wave signals.
The main controller obtains the time when the first sound wave receiver receives the sound wave signals from the first sound wave receiver, obtains the time when the second sound wave receiver receives the sound wave signals from the second sound wave receiver, and then calculates the distance between the first sound wave receiver and the sound wave generator and the distance between the second sound wave receiver and the sound wave generator according to the time when the sound wave generator sends the sound wave signals.
Meanwhile, the first sound wave receiver and the second sound wave receiver are installed in two corners of the room of the conference room, and the distance between the first sound wave receiver and the second sound wave receiver is the length of one wall of the room of the conference room. Therefore, the main controller can calculate the position of the sound wave generator in the conference room by adopting a triangle method according to the distance between the first sound wave receiver and the second sound wave receiver, the distance between the first sound wave receiver and the sound wave generator and the distance between the second sound wave receiver and the sound wave generator.
For example, as shown in fig. 5, a corner of a room in a conference room is used as an origin of a coordinate system, and a straight line where two walls of the room in the conference room are located is used as an X axis and a Y axis, so as to establish the coordinate system:
the first acoustic receiver 12 is located at the origin and the second acoustic receiver 13 is located at the other corner of the conference room, and the distance z between the first acoustic receiver 12 and the second acoustic receiver 13 is exactly the length or width of the conference room. The sound generator 11 is provided in a conference room.
Since the width or length of the room is known. When the sound wave generator 11 emits a sound wave signal and is received by two sound wave receivers, the first sound wave distance L1 and the second sound wave distance L2 can be calculated. The first acoustic wave distance L1 is a distance between the acoustic-wave generator 11 and the first acoustic-wave receiver 12, and the second acoustic wave distance L2 is a distance between the acoustic-wave generator 11 and the second acoustic-wave receiver 13.
The distance from the sound generator 11 to the wall surface of the conference room can be obtained by the pythagorean theorem according to the distance z between the first sound receiver 12 and the second sound receiver 13, the first sound distance L1, and the second sound distance L2, so as to obtain the position of the sound generator 11. Thus, the positioning button is mounted at the position of the sound generator 11, i.e., the repositioning of the positioning button is achieved.
Preferably, a stepping motor is mounted on the microphone slide rail. And the microphone on each microphone slide rail is respectively connected with the corresponding stepping motor. The stepping motor is electrically connected with the main controller.
The microphone moves on the microphone slide rail under the control of the stepping motor.
When the main controller obtains the position of a speaker and recognizes the microphone closest to the speaker, the main controller sends a control instruction to the stepping motor, so that the stepping motor controls the microphone closest to the speaker to move on the microphone sliding rail and move above the position of the speaker, and then the microphone is started to realize the speech reception of the speaker.
