Abstract

An intelligent sound field control system, which relates to a sound field modulation device and is provided with a WiFi/wireless/wire network main control device, a notebook computer, a wireless universal serial bus dongle, a tablet computer, a motion control electronic device and a reflecting medium, is capable of integrally controlling states of different sound reflecting mediums. Accordingly, an indoor acoustic parameter can be varied and electromechanical integration can be achieved, thereby promoting usage convenience, accuracy and usability.

Claims

1. An intelligent sound field control system characterized in that a WiFi/wireless/wire network main control device, a notebook computer, a wireless universal serial bus dongle, a tablet computer, a motion control electronic device and a reflecting medium are provided, the WiFi/wireless/wire network main control device is respectively connected to an optional man-machine operation device notebook computer, the tablet computer and multiple sets of motion control electronic devices through an optional WiFi, or wireless or wire network, the wireless universal serial bus dongle is an optional wireless communication device that is utilized for connection of the man-machine operation device notebook computer, the tablet computer and the WiFi/wireless/wire network main control device, the WiFi/wireless/wire network main control device is utilized for response to a reflecting medium state control instruction transmitted from the notebook computer or the tablet computer, the reflecting medium state control instruction is accordingly utilized to control the corresponding motion control electronic device so that a purpose of collectively controlling each reflecting medium state can be attained and state information of each reflecting medium state can be fed back, and the WiFi, or wireless or wire network is an optional system communication.

2. The intelligent sound field control system as claimed in claim 1 characterized in that at least one of a flat-plate type reflecting plate array, a reflecting triangle conformation array, and a suspension type spherical reflecting plate array is adopted by the reflecting medium.

3. The intelligent sound field control system as claimed in claim 2 characterized in that the flat-plate type reflecting plate comprises a first surface formed as a reflective material layer and a second surface formed as an acoustic absorptive material layer.

4. The intelligent sound field control system as claimed in claim 2 characterized in that three surfaces of the reflecting triangle conformation are formed as material layers provided with different acoustic absorptive coefficients.

5. The intelligent sound field control system as claimed in claim 2 characterized in that the suspension type spherical reflecting plate comprises a lower part formed as a reflective material layer and an upper part formed as an acoustic absorptive material layer.
