Abstract
The invention discloses an intelligent terminal alarm circuit. A plurality of common light-emitting diodes and a clamping circuit, together with an intermittent pronunciation type buzzer, are combined together, then, under the action of a plurality of direct current acousto-optic driving voltage signal sources U, combined acousto-optic information of single sound/source single light source or single sound source/multi-light source can be produced. The invention has the advantages that a common light-emitting diode of very low price, following with the intermittent pronunciation type buzzer, is enabled to produce acousto-optic alarm information in mode of intermittent buzz sound and intermittent flashing light emission, the acousto-optic alarm information is necessary for various acousto-optic alarm equipment and devices, so that for the equipment and devices, extra expense in material cost due to purchase of auto-flashing type light-emitting diodes of very high price can be saved.
Description
Technical field
The present invention relates to the generation of simple sund source/list or multiple light courcess combined type sound/light (warning) signal; Especially let the clipped type hummer of single or many common light emitting diodes and a sense of hearing aspect; Driven by single channel or multichannel (single kind or multiple) information source, the light information that sends the flashing type visual aspects identical with autoflash type light emitting diode comes.
Background technology
Only use a hummer to add single or many signal lamps for having designed; Serve as the device or the equipment of acousto-optic (warning) output function and so on; In order to increase aspect the sense of hearing and the visual notice effect; The conventional practice is the original driving DC voltage signal with continued presence; The voice signal that acts on sense of hearing aspect respectively produces on the wigwag generation device light emitting diode of device hummer and visual aspects, and then message ceases and intermittent mode sends the light information of flicker to let it sound a buzzer with interrupted mode respectively separately.Along with popularizing of electronic integrated circuit technology; Aspect the electronic devices and components of generation sound and these two kinds of transducing purposes of light; Can be automatically with the independent electronic device of intermittently interrupted type way of output work: clipped type hummer and autoflash type light emitting diode; The minister of public works in ancient china is used on market already, and the user only needs still to apply the DC driven signal of regulation by standard practice respectively to them, just can obtain satisfied result.But the price that the concrete fact that can not ignore is arranged is exactly two kinds of devices all has raise, and the price of especially autoflash type light emitting diode is than high times of common light emitting diode! Obviously, for this acousto-optic (warning) device or the equipment, with the cost that increases the starting material aspect for simple sund source multiple light courcess and so on.
Summary of the invention
The object of the present invention is to provide a kind of interior those original auxiliary circuits such as self-timing and electronic switch that only were provided with of clipped type buzzing body that make for the clipped purpose; Simultaneously can be the common light emitting diode service of price than much lower times of autoflash type light emitting diode; Make it to be provided with under the prerequisite, also can send the intermittence flashing type identical (report to the police and use) wigwag with autoflash type light emitting diode at no extra circuit ancillary hardware.
