Further, described the first controller links to each other by universal serial bus with second controller.
Further, described the first controller is connected with the first communication module, and described second controller is connected with the second communication module, and the first controller links to each other with the second communication module by the first communication module with second controller.
Further, also be connected with power amplification circuit between described the first controller and the described loud speaker.
Further, described order input module be button and/touch-screen.
Compared with prior art, Baffle Box of Bluetooth control circuit described in the utility model, carry out Bluetooth pairing in the Baffle Box of Bluetooth startup, the perhaps Play Control of Baffle Box of Bluetooth, during volume adjusting, can carry out Play Control by inputting corresponding control command with the first order input module of the first controller, audio amplifier for closely control inconvenience, can receive the control command of being inputted by the second order input module by the audio amplifier second controller in addition that is arranged at that links to each other with the first controller, received the control command of the second order input module input by second controller control, send it to first controller, resolved the order that transmits by the first controller, control is play, thereby realize non-closely control, make sound-box device can adapt to various control requirement, improve ease of use.
Description of drawings
Fig. 1 is the Bluetooth audio device control circuit connection diagram that the utility model provides;
Fig. 2 is another Baffle Box of Bluetooth control circuit connection diagram that the utility model embodiment provides.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model provides a kind of Baffle Box of Bluetooth connecting circuit, its purpose is to overcome the problem of control inconvenience in the prior art, on the basis of existing Baffle Box of Bluetooth controller, can increase by a controller, adjusted control, newly-increased controller can be set up button etc. as required in addition, improves the user convenience that uses and the flexibility that improves equipment.
As shown in Figure 1, Baffle Box of Bluetooth control circuit described in the utility model comprises the first controller 2 that links to each other with loud speaker 1 that is arranged at the audio amplifier content, and described the first controller 2 connects the first order input module 3.Controller 2 is sent to loud speaker after the voice data that is received by the Bluetooth transmission module can being processed, the order input module that links to each other with the first controller, can be button or touch-screen etc., operated by rotary motion has the startup button, be used for starting power supply, bluetooth module enters the search pairing mode, can also comprise that in addition the practical example of the utility model can comprise above-mentioned button but be not limited to above-mentioned set-up mode such as playing redirect button, volume increase and decrease button etc.Above-mentioned the first instruction control unit can also be finished the control and management to miscellaneous equipment, such as machine module between memory, bluetooth module, receipts etc., to realize the greater functionality of Baffle Box of Bluetooth.
Described the first controller 2 also links to each other with the second controller 4 that is arranged at the audio amplifier outside, second controller 4 connects described the second control order input module 5, the second control command input module can be input key, also can be touch-screen, situation flexible choice according to control appliance, this connected mode can realize the control mode of Baffle Box of Bluetooth is expanded, in the situation for control mode inconvenience closely, can send control command by second controller 4, the first controller 2 is after receiving control command and resolving, realize corresponding control action, this connected mode has positive effect for the flexibility that improves control.
In a kind of connected mode of two controllers shown in Figure 1, described the first controller and second controller can but be not limited to by universal serial bus and link to each other, (English full name is Inter-Integrated Circuit to serial bus, and is English referred to as I
2C) bus), serial bus is as communication bus of usefulness all, realizes simply, and general controller itself all can with such interface, can be realized the control expansion to the first controller easily.
As shown in Figure 2, connected mode for the another kind expansion, described the first controller 2 is connected with the first communication module 6, and described second controller 4 is connected with the second communication module 7, the first controllers 2 and links to each other with the second communication module 7 by the first communication module 6 with second controller 4.The selection of communication module can be versatile and flexible, such as the ripe bluetooth communication module that the AVRCP agreement controls etc. that passes through on the market, because sound-box device described in the utility model itself has bluetooth module, by second controller, for equipment such as employed mobile phones in people's life, generally all with bluetooth communication module, can realize easily that therefore second controller controls by bluetooth.Can certainly or adopt the mode of other communication connection to finish the transmission of control command for other communication protocol.
