Description

A kind of voice broadcast radio

Technical field

The invention belongs to the technical field of Smart Home and intelligent appliance, be specifically related to radio in specific crowd (vision Bad old man and blind person) in user individual service customization demand.

Background technology

Along with the development of science and technology, increasing electronic product occurs in the middle of our life, and such as hands is mechanical, electrical Depending on, wearable portable equipment, these emerging electronic products, in our life of enriching constantly, make our life more Interesting and convenient.And radio is as the electronic equipment of a generation the earliest, still account for the biggest ratio in person in middle and old age market.And Nowadays intelligent equipment has been irreversible trend, and the generation of voice system makes people break away from the constraint of eyes, to people Life bring great convenience.Furthermore, it mainly uses colony's middle-aged and elderly people vision can have with the growth at age and significantly moves back Change, the design of slight radio display screen obviously hommization not, it is impossible to meet the demand of user.

But now, most of language play back systems that market is sold, it is all employing order recording, is the most from the beginning multicast to Tail, it is impossible to realize the function of selections broadcasting, loop play.And along with the raising of state-of-art, modern wireless system Increasingly reach digitized and integrated, and cost is more and more lower, more stable, convenient compared with traditional radio. Integrated be advantageous in that the function that can add other easily on original function basis, and now TEA5767 system Row single-chip microcomputer digital element radio has been widely used in all kinds of handheld electric products such as such as mobile phone, MP3 etc..This radio reception Machine, has less, less expensive, consumes the various advantages such as less power.

Summary of the invention

The present invention is directed to the deficiencies in the prior art, it is provided that a kind of voice broadcast radio.

The present invention solves the technical scheme that technical problem taked:

The present invention include TEA5767 radio module, STC89C52 one-chip computer module, voice broadcast module, audio amplification block and Keyboard, STC89C52 one-chip computer module is respectively with TEA5767 radio module, voice broadcast module, audio amplification block signal even Connect；Wherein STC89C52 one-chip computer module uses I2C bus to be connected with TEA5767 radio module, and is controlled by I2C bus The work of TEA5767 radio module, two I/O pins of the P2 mouth on STC89C52 one-chip computer module carry out analogue I2C bus SCL and SDA sequential.

Audio amplification block uses power amplifier module TDA2822 or power amplifier module PMA8403；Potentiometer is used to control The volume of the audio signal of the left and right acoustic channels of TEA5767 radio module output, is then input to power amplifier module and carries out power amplification, Finally enter speaker, play out sound.

Voice broadcast module use YN3P010B speech chip, the 6 of this chip, 7,8 pins respectively with on one-chip computer module Three I/O pins of P3 mouth connect, described YN3P010B speech chip burning has the audio file recorded, one-chip computer module Read the data of speech chip, and play voice by tone playing equipment.

Described keyboard is connected with STC89C52 one-chip computer module signal, button detected by STC89C52 one-chip computer module Signal, and realize wireless manual tune platform through the control of STC89C52 one-chip computer module, automatically adjust platform.

Beneficial effects of the present invention: the present invention devises one and can be applied in radio with the circuit that selections are play, its Blind users can be made to rely on voice message to select radio station, remove people from by seeing the trouble of screen channel selection.

Detailed description of the invention

The design of the present embodiment has two parts respectively: one, uses the STC89C52 chip of macrocrystalline to do master control, brings control The TEA5767 radio module of PHILIPS Co.'s new production, makes a Radio system.Two, the most again with the master of single-chip microcomputer Control voice broadcast module, finally integrate, make a Radio system with voice broadcast frequency of radio station, ginseng See Fig. 1.Whole system can be operated by keyboard, the signal of button detected and through the control of single-chip microcomputer by single-chip microcomputer System realizes the functions such as wireless manual tune platform, automatically tune platform.

As in figure 2 it is shown, most important part is exactly that FM receives circuit in voice broadcasting system, this is crucial institute ?.The most most important core devices that the present embodiment is used is the TEA5767 of the single-chip as this FM reception circuit.

As it is shown on figure 3, whole main control part is more complicated, the most most importantly single-chip microcomputer STC89C52, also wraps Circuit containing periphery, wherein has reset circuit, crystal oscillating circuit etc..Single-chip microcomputer master control uses I2C bus to carry out the module phase with radio reception Even, and wireless normal work is controlled by I2C bus.Two P2 mouths of STC89C52 single-chip microcomputer have been used in this design The I/O pin of (P26, P27) carrys out SCL and the SDA sequential of emulation bus, communicates with TEA5767 module.

As shown in Figure 4, the topmost device of display circuit is exactly LCD1602, by the connection with single-chip microcomputer master control, receives After the signal of single-chip microcomputer, demonstrate content, operations and operating result, and the frequency in radio station can demonstrate from LCD Come.

The supply voltage of single-chip microcomputer STC89C52 chip is 5V, it is provided that power supply circuits as shown in Figure 5 provide one and stablize Voltage.The 5 V constant voltages that power module of voltage regulation produces can be that the device of modules is powered

As shown in Figure 6, the signal received by radio by this circuit function is amplified amplifying circuit, so can clearly hear The radio content that radio receives.

Voice broadcast circuit, as it is shown in fig. 7, carried out selections by Single-chip Controlling umber of pulse, reports the voice recorded in advance in advance. The all operations of NY3P010B speech chip is by Single-chip Controlling.

The present invention is directed to lacking of radio intellectuality aspect design, it is provided that integrated level is high, develop perfect radio Voice broadcasting system, reaches Intelligent Recognition frequency of radio station, the purpose of voice broadcast frequency of radio station.
