Abstract
The utility model relates to an electron alarm clock circuit, in particular to a self-recording alarm addition circuit. The technical proposal of the utility model is that: the sound recording and playing circuit consists of an self sound recording and playing integration circuit IC, a button AN a mike MIC and a loudspeaker; the control circuit consists of a diode D, a resistance R and a dynatron BG; and the self sound recording and playing integration circuit IC is formed by connecting a battery DC and a switch K. The utility model is simple in structure, convenient to be mounted and can be arranged on various alarm clocks which are supplied by batteries, realize voice remaining function and tape voice reminding voice by oneself; moreover, the utility model has a better meaning to the cultivate time concept and interests to children.
Description
Technical field
The utility model relates to the electronic alarm clock circuit, specifically is the adjunct circuit that makes a noise that cries that has from recording.
Background technology
Present all kinds of alarm clocks, particularly children use small alarm clock, adopt the sibilant rale of electronic chip or music noisy mostly, and are poor to children's attractive force, interest and competitiveness; And point out indeterminate.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, provides a kind of voice of can realizing noisy function, and the circuit that makes a noise is in the additional recording certainly of the alarm clock that makes noisy voice to record voluntarily.
Its technical scheme is: by forming recording and playing circuit from recording playback sound integrated circuit (IC), knob AN, microphone MIC and loudspeaker; Form control circuit by diode D, resistance R and triode BG; Battery DC connects from recording playback sound integrated circuit (IC) and former alarm clock circuitry ZB through K switch.
The utlity model has simple in structure, install additional conveniently, be installed on all kinds of battery powered alarm clocks, can realize voice noisy function, and make noisy voice to record voluntarily.Considering interest meaning is preferably arranged to cultivating children's view of time.
Description of drawings
Accompanying drawing is the circuit theory diagrams of a kind of embodiment.
Embodiment
Be further described with regard to its principle of work below in conjunction with accompanying drawing:
Among the figure by forming recording and playing circuit from recording playback sound integrated circuit (IC), knob AN, microphone MIC and loudspeaker; Form control circuit by diode D, resistance R and triode BG; ZB is former alarm clock circuitry.
When former alarm clock circuitry ZB has alarm clock signal when output, this signal is through diode D, resistance R trigger triode BG conducting, thereby makes from the work of recording playback sound integrated circuit (IC), emits the voice that record in advance.During recording, the K2 that at first closes a switch presses knob AN and begins to speak facing to microphone MIC, unclamps knob AN after finishing, and cut-off switch K2 can use then.
Claims (1)
1. alarm clock is additional is the circuit that makes a noise from recording, it is characterized in that: by connecting to form recording and playing circuit from recording playback sound integrated circuit (IC), knob (AN), microphone (MIC) and loudspeaker (L); Form control circuit by diode (D), resistance (R) and triode (BG); Battery (DC) connects from recording playback sound integrated circuit (IC) and alarm clock circuitry trigger circuit (ZB) through switch (K).
