Abstract
The invention relates to a loudspeaker box being capable of wirelessly controlling the volume; the loudspeaker box is characterized in that the loudspeaker box being capable of wirelessly controlling the volume comprises four parts which are a wireless transceiving module A, a control circuit B, a line transformer C and a loudspeaker D; the wireless transceiving module A can be the known wireless transceiving modes such as frequency modulation, amplitude modulation, infrared, Bluetooth and the like; the wireless transceiving module A can use the address bit of a decoding module thereof or the combination of the address bit and the data bit for determining the identify identification information of the loudspeaker D; and the loudspeaker D can be the known loudspeaker modes such as a ceiling-mount loudspeaker, a wall hanging loudspeaker, an outdoor waterproof loudspeaker and the like.
Description
Technical field
The present invention relates to a kind of audio amplifier, but a kind of audio amplifier of wirelessly controlling volume particularly.
Background technology
It all is unified volume basically that the loud speaker of existing Public Address system amplifies, and for solving the demand of a certain loud speaker to volume, need install independently volume adjuster again additional.
Such scheme exists needs independent wiring, digs problems such as metope again.Cause the serious wasting of resources.
Summary of the invention
In sum, but the invention provides a kind of audio amplifier of wirelessly controlling volume, can under the condition of laying-out not, realize purpose independent speaker volume control.
But the audio amplifier of wirelessly controlling volume of the present invention is characterized in that: but the audio amplifier of described wirelessly controlling volume is made up of wireless transceiving module A, control circuit B, line transformer C, loud speaker D four parts; Described wireless transceiving module A can be known wireless transceiving modes such as frequency modulation, amplitude modulation, infrared, bluetooth; Described wireless transceiving module A can be determined the identity identification information of loud speaker D with the combination of the address bit of its decoder module or address bit and data bit; Described loud speaker D can be known loud speaker forms such as ceiling loudspeaker, wall hanging loud speaker, outdoor water-proof loud speaker.
Description of drawings
But accompanying drawing is the constituent components figure of the audio amplifier of wirelessly controlling volume.
* accompanying drawing major part symbol description *
A1: the transmitter module of wireless receiving and dispatching module
A2: the receiver module of wireless receiving and dispatching module
B: control circuit
C: line transformer
D: loud speaker
Embodiment
Consult accompanying drawing, but the audio amplifier of the present invention's wirelessly controlling volume is made up of wireless transceiving module A, control circuit B, line transformer C, loud speaker D four parts.Wireless transmitter module A1 provides control command and is received by wireless receiving module A2, correspondence on behind the address bit corresponding data bit provide a high level to control circuit B, control circuit B connects corresponding line transformer C power output signal to loud speaker D.
Described each functional module of accompanying drawing all belongs to general and mature technique, and can adopt multiple scheme to realize, though the scheme that realizes can be ever-changing, its basic principle is the same.
