Description

A kind of pull bar active loundspeakers with charge and discharge protecting function
Technical field
This utility model relates to stereo set, particularly relates to a kind of pull bar active loundspeakers with charge and discharge protecting function
Background technology
In recent years, along with enriching constantly of people's material and cultural life, people are more and more urgent to the demand of spirit amusement etc. Cut;The most more it is suitable for the amusements such as popular predominantly square dance;In order to preferably meet masses' demand and develop emerging city , people have carried out various innovation for this, as in order to obtain the most outdoor sound equipment broadcasting experience, have developed special outdoor sound Ring.
The special sound equipment in the most representative open air is pull bar sound equipment, and it has been widely used for modern trend and intelligence In life, at present, pull bar sound technique quickly grows, and people are more and more higher to the requirement of acoustic product, and either hardware is still The functions such as control, data transmission and play operation all cannot meet the multiple demand that people the most quickly increase.
Utility model content
The purpose of this utility model is to provide a kind of pull bar active loundspeakers with charge and discharge protecting function, and it has safety Reliably, Stability Analysis of Structures is compact and operates with advantage simply and easily.
The utility model is achieved like this, a kind of pull bar active loundspeakers with charge and discharge protecting function, it includes Main control chip, power amplifier and accumulator, it is characterised in that it also includes being connected on main control chip for controlling accumulator The protection circuit of discharge and recharge.
Described main control chip is also connected with for connecting the touch screen that electricity shows and plays control.
This active loundspeakers also includes that bluetooth module and audio input interface, described bluetooth module connect master control core respectively Sheet, AUX input module, NFC module and USB module.Described audio input interface is guitar and mike input interface.
Preferably: described accumulator is the lead-acid battery of built-in 12V/10A.
Preferably: described power amplifier include having the overvoltage of auto restore facility, under-voltage, overheated, DC detection and Short-circuit protection circuit
The beneficial effects of the utility model are: this utility model compact conformation is practical, and it passes through charge and discharge protecting, it is possible to Protect internal electronic device in the case of abnormal electrical power supply in time, improve the security reliability used;It is right to be achieved by touch screen The real-time control play, improves convenience and the reliability of operation, further through Bluetooth architecture, can realize distant control with many The synchronization broadcasting that media are compatible, so substantially increases variation and convenience that sound equipment controls so that it is preferably meet each Plant the needs that audio frequency is play by occasion.
Accompanying drawing explanation
Fig. 1 is structural principle block diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.
As it is shown in figure 1, this utility model be achieved in that described in there is the pull bar active loundspeakers of charge and discharge protecting function Including main control chip, power amplifier and accumulator, it is structurally characterized in that, it also includes being connected on main control chip for controlling The protection circuit of accumulator cell charging and discharging.When battery being detected close to nothing electricity, main control chip automatically controls sound equipment and quits work, when Detect that battery has been filled with electricity and will be automatically stopped charging, so can reduce long-time charging and the overdischarge damage to battery, prolong Long battery.In order to improve the safety and reliability of sound equipment work further, described power amplifier includes having certainly The overvoltage of dynamic recovery function, under-voltage, overheated, DC detection and short-circuit protection circuit, can realize the real-time guard to power amplifier, Avoid the occurrence of abnormal voltage and line fault along bad Key Circuit, reduction maintenance cost, the reliability and durability property of raising work.
In order to improve the convenience of operation, described main control chip be also connected with for connect electricity show with play control touch Touch screen.In the specific implementation, main control chip uses AX2060 main control chip, and AX2060 main control chip is a high-performance, low one-tenth Originally, the multiformat decoder chip of high competitiveness, it is adaptable to its support low power consuming clock of multiple application product shows, built-in RTC Module, under system worked well pattern, the speed of service is fast, and disposal ability is strong, in stand-by mode, has good standby merit Consumption, quiescent current is little;Can realize play signal and volume etc. being play the control arranged and playing content by touch screen Regulation, visualizes, easy and simple to handle.
Each input and data transmission structure are also improved by this utility model, and this active loundspeakers also includes bluetooth Module and audio input interface, described bluetooth module connects main control chip, AUX input module, NFC module and USB mould respectively Block.Wherein bluetooth module uses bluetooth CSR4.0 version BT1213H module;BT1213H uses CSR8635 bluetooth to support V4.0+ EDR bluetooth standard, supports the clear stereo output of SBC, MP3, AAC audio format, low-power consumption, supports music and call merit Can, support CSR up-to-date CVC noise elimination function;In use, select the bluetooth on equipment (mobile phone etc.), open bluetooth discovery Going out the implementor name of sound equipment, click on connection and may be selected by music, when bluetooth is not attached to equipment, indigo plant lamp dodges, and is connected to set Standby rear blue lamp length is bright;NFC module also supports NFC wireless near field communication music simultaneously.
Described audio input interface is guitar and mike input interface, is furnished with guitar and microphone inlet can be easy to family Outer bullet is sung;In order to preferably meet the long-time needs play, described accumulator is the lead-acid battery of built-in 12V/10A.
