Description
[technical field]
The utility model relates to a kind of resonance sound equipment, refer in particular to a kind of can be by wireless mode and the extraneous resonance sound equipment that carries out data interaction.
[background technology]
Continuous development along with technology, this new product of resonance sound equipment had appearred in recent years, it changes the sounding principle of sound equipment traditional mode in the past, by with audio signal, being converted to audio frequency vibration passes to the sounding medium and makes the medium sounding, medium takes place can be various common as wooden desktops, glass, the floor, metal covering, rigid planar such as metope, we can say that the resonance sound equipment has proposed new notion in the development of electro-acoustic element, it does not have loudspeaker stereo, but the dynamics appeal that can send vocal music is extremely strong, especially the telepresenc of musical instrument resembles the scene reduction of concert, product manufacture deep in interior and beautiful in outside, to bring the user unprecedented fashion shock, therefore since it comes out, just be subjected to pursuing of consumers in general always.
Yet existing resonance acoustic product can only be single plays after passing through tone frequency channel wire and player being connected, and use to go up to be subjected to many restrictions, and tone frequency channel wire drags line very inconvenience outside, and therefore portability is relatively poor.
[summary of the invention]
The purpose of this utility model is to have overcome above-mentioned defective, and a kind of resonance sound equipment with wireless data communication is provided.
The purpose of this utility model is achieved in that a kind of resonance sound equipment with wireless data communication, it comprises audio input port, operational amplifier, power amplifier and audio driver, the operational amplifier input connects audio sockets, output is connected to power amplifier, power amplifier links to each other with audio driver, its improvements are: it has also included wireless receiving/transmitter module and antenna, and wireless receiving/transmitter module links to each other with antenna, and links to each other with audio driver by operational amplifier, power amplifier;
In the said structure, described operational amplifier comprises that a model is the amplifier chip of LM358;
In the said structure, described power amplifier comprises that a model is the power amplifier chip of SJ8305D;
In the said structure, described wireless receiving/transmitter module includes the WIFI communication unit;
In the said structure, described wireless receiving/transmitter module includes the bluetooth communication unit;
