The wireless sound boxes such as existing WIFI, bluetooth and 2.4G, between audio amplifier in the environment for use such as spacing comparatively far away, ambient shield serious, RF serious interference, there will be communication wild effect, directly affect audio frequency result of broadcast, there will be intermittently, the phenomenon such as noise.
Utility model content
The utility model there will be communication wild effect when communication distance is far away by environmental factor interference for solving existing wireless sound box, directly affects the problem of audio frequency result of broadcast.
The technical scheme in the invention for solving the technical problem is: audio amplifier, comprise master controller, power module, power amplifier and interface driver module, described master controller and power module, power amplifier and interface driver model calling, described power amplifier is connected with loudspeaker, described interface driver model calling has USB interface, SPDIP interface, SD card plug, HDMI and analog interface, also comprise wireless communication module and power line carrier, PLC module, described wireless communication module and power line carrier, PLC module are connected with described master controller.
Described USB interface, SPDIP interface, SD card plug, HDMI and analog interface are at least one, and described USB interface, SPDIP interface and SD card plug and loudspeaker are arranged on same.
Particularly, described wireless communication module is WIFI module, bluetooth module or 2.4G wireless module.
When needs multitone case works simultaneously, the utility model provides a kind of sound box system further, comprise at least 2 above-mentioned audio amplifiers, also comprise router, connected by supply line and/or radio connection between described audio amplifier, have at least an audio amplifier to be connected with router, described router is connected by radio connection with between audio amplifier.
A preferred scheme is: described audio amplifier is 6, be respectively main sound box, the first audio amplifier, the second audio amplifier, the 3rd audio amplifier, the 4th audio amplifier and five notes of traditional Chinese music case, described main sound box is connected with router, and described main sound box is connected by supply line with the first audio amplifier, the second audio amplifier and the 4th audio amplifier respectively.
The beneficial effects of the utility model are: the utility model inserts wireless sound box by PLC, use existing power line as transmission medium, system, according to active wireless network environment, is selected wireless or PLC as communication channel, is possessed the convenience of wireless sound box and the high-quality of wired audio amplifier simultaneously.The communication efficiently solved when communication distance is far away between audio amplifier between audio amplifier is disturbed by environmental factor thus affects the problem of audio frequency result of broadcast.
Accompanying drawing explanation
Fig. 1 is the utility model loudspeaker box structure principle schematic.
Fig. 2 is the sound box system structural representation of embodiment.
Embodiment
Be further described the technical solution of the utility model below in conjunction with drawings and Examples, embodiment is only used to help reader to understand technical solutions of the utility model better, and should not be understood as the restriction to the utility model protection range.
As shown in Figure 1, the utility model provides a kind of audio amplifier, comprise master controller, power module, power amplifier and interface driver module, described master controller and power module, power amplifier and interface driver model calling, described power amplifier is connected with loudspeaker, described interface driver model calling has USB interface, SPDIP interface, SD card plug, HDMI and analog interface, also comprise wireless communication module and power line carrier, PLC module, described wireless communication module and power line carrier, PLC module are connected with described master controller.
Embodiment
For the sound box system audio plays of 6 audio amplifier compositions, describe the operation principle of audio amplifier and sound box system in detail, in this example, the wireless communication module of audio amplifier is WIFI module.
As shown in Figure 2,6 audio amplifiers are respectively main sound box, the first audio amplifier, the second audio amplifier, the 3rd audio amplifier, the 4th audio amplifier and five notes of traditional Chinese music case, described main sound box is connected with router, and described main sound box is connected by supply line with the first audio amplifier, the second audio amplifier and the 4th audio amplifier respectively.
In audio amplifier, the function of each device blocks is as follows:
Power module: be each module for power supply, simultaneously for PLC provides clean passage.
WIFI module: the network service such as WIFI DIRECT, AIR PALY, WIFI hot spot, DLNA, WIFI relaying is provided.
PLC module: power line carrier, PLC service is provided.
Interface driver module, for connecting the Peripheral Interface of audio amplifier.
Master controller: detect WIFI signal quality, selects WIFI communication service or plc communication service according to WIFI quality condition.Respond the data transfer demands such as the internet audio of user, aerial broadcasting simultaneously, WIFI module, PLC module are configured, realize the functions such as intelligent power managed, network trunk, hotspot.
After audio frequency in network is pushed to main sound box by router, main sound box is play needing the audio content play to be transferred in other 5 audio amplifiers connected simultaneously, first audio amplifier, second audio amplifier, 3rd audio amplifier, master controller in 4th audio amplifier and five notes of traditional Chinese music case controls this audio amplifier by wired or wireless network and main sound box communication according to the power of the WIFI signal detected, when WIFI signal is enough strong, then use WIFI passage and main sound box communication, if WIFI signal is lower than the signal strength values of setting, then use power line carrier, PLC channel, namely by power line and main sound box communication.
Should be noted that, in upper example, the master controller of audio amplifier needs to use software when judging which kind of mode this audio amplifier uses communicate according to the signal detected, but involved software belongs to prior art completely, the utility model there is no any improvement in software.
