Abstract
The utility model relates to a language broadcasting device which solves the problem that a device is fixedly arranged in a television to automatically broadcast advertisements or lucky words. In the utility model, an RC time delay circuit is used for controlling a base pole of a triode, and a relay J is connected with a collecting electrode of the triode to form a time delay control circuit. A language integrated circuit YY is controlled by a normally open contact JK of the relay J to switch on a working power supply. Therefore, the signals of the advertisement words or the signals of the lucky words stored in the language integrated circuit YY are output to a loudspeaker L. The utility model has the advantages of simple structure and low cost and is suitable for televisions, various domestic electric appliances, cars, etc.
Description
The utility model relates to a kind of device of playing language, can be from the device of advertisement or auspicious words during particularly a kind of television startup.
The sound accompaniment sounding that program that existing television set generally can only broadcast according to TV station or video tape recorder are put video tape, self can not set the language sounding, and the device of utilization itself just can't realize for own broadcast advertising slogan or auspicious words if this television set be can't come round to the idea TV station or video tape.If a kind of language device can be installed on television set, manufacturer just can increase function for the product of oneself, perhaps can give the wish of a luckiness of users.
It is a kind of simple in structure that the purpose of this utility model is to provide, and can broadcast the advertisement sound of setting or the device of auspicious words sound when television boot-strap preheating picture tube automatically.
The utility model is finished with following mode: the RC delay circuit electricity that is made of capacitor C series resistor R from advertisement or auspicious words device during television startup connects the base stage of triode BG and forms delay control circuit; Serial connection relay J coil on the collector electrode of triode BG, the normal opened contact JK of relay J is serially connected between the supply terminals of DC power supply and language integrated circuit YY, is connected to loud speaker L at the output of language integrated circuit YY.Delay control circuit is by on the DC power supply that is attempted by the control of television set switch behind the capacitor C series resistor R, and electricity connects the base stage formation of triode BG behind electric connecting resistance R1 between capacitor C and the resistance R.Or by being attempted by on the DC power supply behind the capacitor C serial connection diode D, electricity connects the base stage formation of triode BG behind series resistor R between capacitor C and the diode D.What store among the language integrated circuit YY is advertising language or lucky language.
The utlity model has simple in structure, cost is low, fixed storage advertisement language or store lucky language in the language integrated circuit, can enlarge to manufacturer and know lightness, increase television function, or when opening television set, broadcast a fine luckiness for vast TV user at every turn and wish, bring joy to the user.This device utilizes a delay control circuit control language integrated circuit to carry out work when the television picture tube preheating, and stops the integrated circuit working of language when the television set operate as normal automatically, can not hinder the normal function of television set.The utility model also can be used for automobile and other household electrical appliance such as radio-cassette player etc., can increase function from advertisement or auspicious words to various product.
Fig. 1 is the utility model embodiment one circuit theory diagrams;
Fig. 2 is the utility model embodiment two circuit theory diagrams.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Embodiment one: as shown in Figure 1, the utility model is to be attempted by on the dc supply after holding C serial connection diode D, and dc supply is controlled by the television set switch.Electricity connects the base stage formation delay control circuit of triode BG behind series resistor R between capacitor C and the diode D, the coil of serial connection relay J on the collector electrode of triode BG, the double-throw contact JK of relay J, its normal opened contact connects supply terminals and the DC power supply of language integrated circuit YY, its normally closed contact connects wiring of television audio circuit power and DC power supply, output termination loud speaker L at language integrated circuit YY, or by meeting loud speaker L behind the power amplifier, language integrated circuit YY can adopt TM80 series integrated circuit, can advertisement language signal or lucky speech signal be stored in wherein by special machine in language integrated circuit YY, diode D is the discharge channel that is used for capacitor C.The course of work is, when television boot-strap, set up dc supply, this direct voltage charges to electrochemical capacitor C immediately, in charging process, electrochemical capacitor C has electric current to flow through, and offers the base stage of triode BG, makes triode BG conducting, and power to relay coil J, the normal opened contact JK adhesive of relay J disconnects its normally closed contact thereupon, reaches to cut off television audio circuit BY, connect language integrated circuit YY, language integrated circuit YY work this moment is exported the advertisement of its storage or lucky speech signal to loud speaker L, and is broadcasted advertising slogan or auspicious words, through after a while, this time, electrochemical capacitor C charging was saturated by resistance R and capacitor C decision, and charging current disappears, triode BG also loses base current thereupon, and BG is ended, and the relay J dead electricity, its normal opened contact JK discharges, and the working power of cut-out language integrated circuit YY, connect the working power of sound accompaniment circuit BY, stop from advertisement or auspicious words, television set enters normal sound accompaniment work.
Embodiment two: as shown in Figure 2, its circuit structure and the course of work are as described in the embodiment one, and different is to use diode D instead resistance R, and other do not repeat.
Claims (3)
1, during a kind of television startup from advertisement or auspicious words device, it is characterized in that the base stage that the RC delay circuit electricity that is made of capacitor C series resistor R meets triode BG forms delay control circuit; Serial connection relay J coil on the collector electrode of triode BG, the normal opened contact JK of relay J is serially connected between the supply terminals of DC power supply and language integrated circuit YY, is connected to loud speaker L at the output of language integrated circuit YY.
2, according to the described device of claim 1, it is characterized in that delay control circuit is by on the DC power supply that is attempted by the control of television set switch behind the capacitor C series resistor R, electricity connects the base stage formation of triode BG behind electric connecting resistance R1 between capacitor C and the resistance R, or by being attempted by on the DC power supply behind the capacitor C serial connection diode D, electricity connects the base stage formation of triode BG behind series resistor R between capacitor C and the diode D.
3, according to the described device of claim 1, what it is characterized in that storing among the language integrated circuit YY is advertising language or lucky language.
