Description

Technical Field

[0001] This utility model relates to the field of monitoring system technology, and in particular to a multi-functional scheduling wireless audio system. Background Technology

[0002] Currently, for live recording in scenarios such as live broadcasts and stage performances, in addition to transmitting the performer's voice signal to the loudspeaker, wireless communication equipment is needed so that the performer can monitor the performance in real time. Simultaneously, the on-site director or stage manager needs to issue control instructions to the performers. However, existing wireless audio systems cannot simultaneously achieve voice monitoring and voice signal transmission, often requiring two independent sets of equipment to operate concurrently. This not only inconveniences on-site control personnel but also causes interference between the devices. Furthermore, existing wireless audio systems do not allow directors or stage managers to have individual conversations with the on-site anchors or singers for real-time control, impacting the ease of use of the wireless audio system.

[0032] The working principle of this utility model will be further explained below.

[0033] In this embodiment, during the use of the multi-functional scheduling wireless audio system, the singer wears instrumental headphones and performs through the instrumental pickup device; the photographer or director, or other coordinator, sends scheduling signals to the singer through a scheduling microphone. After the multi-functional scheduling wireless audio system is paired and connected with the instrumental headphones, the instrumental pickup device, and the scheduling microphone, the first receiving port 110 is connected to the instrumental pickup device through a receiving antenna, and the first transmitting port 120 is connected to the instrumental headphones through a transmitting antenna; the second receiving port 130 is connected to the scheduling microphone through a receiving antenna, and the second transmitting port 140 is connected to the instrumental headphones through a transmitting antenna.

For example, after a singer performs using a performance pickup device, they send a performance audio signal to a receiver. The first receiving port 110 receives the performance audio signal and sends it to the audio processing module 320 via the switching unit 200 and the switch module 310. With the monitoring function enabled, the audio processing module 320 converts the performance audio signal into a monitoring signal and sends it to the switching unit 200.

The second receiving port 130 receives the dispatch audio signal via a receiving antenna and sends it to the audio processing module 320 via the switching unit 200 and the switch module 310. With the dispatch function enabled, the audio processing module 320 converts the dispatch audio signal into a dispatch signal and sends it to the switching unit 200. The second transmitting port 40 transmits the monitoring signal to the right channel of the performer's headphones via a transmitting antenna, achieving wireless dispatch and improving the efficiency of video recording for both the performer and the camera crew. Especially in performances involving long distances, a multi-functional scheduling wireless audio system can be used for remote scheduling and coordination. In practical applications, this system can also support multiple singers wearing instrumental headphones to receive monitoring and scheduling signals, enabling collaborative monitoring and scheduling among multiple singers and improving the system's compatibility.

[0034] Existing performance audio pickup devices all transmit performance audio signals wirelessly to a corresponding receiver, which then converts them into analog signals before transmitting them to the appropriate front-end audio equipment, such as speakers, via audio cables to achieve sound amplification. However, this method cannot simultaneously enable the performer to receive monitoring and orchestration signals through their headphones, which greatly affects the ease of use of the receiver.

[0035] As can be seen from the above description, the multi-functional scheduling wireless audio system of this utility model, by setting up an interface unit 100 and a switching unit 200, allows the interface unit 100 to receive performance audio signals and scheduling audio signals, and simultaneously send monitoring signals and scheduling signals, thus realizing voice monitoring and real-time communication functions, improving the ease of use of the multi-functional scheduling wireless audio system; by setting up a switching unit 200 and a control unit 300, the audio processing module 320 can receive and process performance audio signals and scheduling audio signals through the switching module 310, and send monitoring signals and scheduling signals to the switching unit 200 through the switching module 310, improving the operating efficiency of the multi-functional scheduling wireless audio system and enhancing the user experience; through By setting up receiving and transmitting antennas, the connection stability between the first receiving port 110 and the performance pickup device, and between the first transmitting port 120 and the performer's headphones, is ensured, thus guaranteeing the transmission stability of the performance audio signal and the monitoring signal. By setting up the first control transistor Q1, the second control transistor Q2, the third control transistor Q3, and the fourth control transistor Q4, the switching module 310 can quickly turn on or off the transmission of the scheduling audio signal, the scheduling signal, the scheduling audio signal, and the scheduling signal, thereby improving the response speed of the scheduling audio signal and the scheduling signal. By setting up the current limiting resistor 311, excessive current is avoided between the switching module 310 and the audio processing module 320, thereby improving the operational stability and service life of the scheduling audio signal and the scheduling signal.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
