Abstract
The utility model relates to a message leaving device, composed of a language input circuit, a language synthesis chip, an amplifying circuit, a switch circuit, a power circuit, a loudspeaker, a shell, etc. The utility model has the characteristics of simple structure, small volume, low production cost, convenient use and carrying, etc. and can be conveniently used for the occasions such as families, offices, etc.
Description
The utility model belongs to electronic technology field, is specially a kind of message device.
Prior art the message device that extensively adopts be a kind of sound-track engraving apparatus that constitutes by magnetic medium and complicated mechanical, its manufacturing cost height of this kind message device and use inconvenience.Chinese patent (CN2144835Y) once disclosed a kind of electronic door bell message device, and it is made up of pure electronic devices and components, and has avoided necessary magnetic medium of sound-track engraving apparatus and complicated mechanical devices, except that using as doorbell, also can be used for putting down in writing guest's message.But still there is the circuit structure complexity and carries inconvenient shortcoming.
The purpose of this utility model provides that a kind of circuit structure is simple, and production cost is low, carries and message device easy to use.The purpose of this utility model is to realize like this; The utility model comprises speech input circuit (1), language synthesis chip (2), amplifying circuit (3), on-off circuit (4), power circuit (5), loudspeaker (6) and shell (7) etc., and wherein, speech input circuit (1) is by IR
