Abstract
The utility model relates to an electron speech sound map with sound playing function. The electron speech sound map consists of a plastic shell 3 and a plane map whole 4, wherein, sensing touch points are arranged on the inner surfaces of specified positions of the plane map; the sensing touch points are connected with a sound playing device 2 as a switch of the sound playing device 2. The structure of the sound playing device 2 is that: a sound IC integrated chip 9 is connected with touch points 15 through an oscillation circuit 16 and a digital-analog conversion circuit 17; the digital-analog conversion circuit 17 is connected with an audio amplifying circuit 12 and an electrodynamic loudspeaker 11 via an audio line 14; the electrodynamic loudspeaker is connected with a zero line connecting device 13 and a power supply connecting line 10 which is connected with a power supply accessing line 18; the sound IC integrated chip 9 is connected with the power supply accessing line 18. The utility model has the advantages of the capability of being read, producing sound through touch and being heard, thereby improving the using interests of people. Meanwhile, the utility model is convenient to carry because of simple design and a cleverish structure.
Description
Technical field
The utility model relates to a kind of map, particularly relates to a kind of electronic speech map with voice play function.
Background technology
Existing map is usually used in people's studying the geography knowledge, grasps the usefulness in geographic position, and it adopts draws various geographical units on three-dimensional sphere or plane, but function singleness has only indicative function, can not sounding, and inconvenience carries, and outward appearance is also plain.
Summary of the invention
Technical problem to be solved in the utility model is to overcome present map can not play sound and carry inconvenient shortcoming and a kind of electronic speech map that can play voice is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
The electronic speech map is made up of plastic casing and plane map integral body, and the sensing touch point is arranged on the inside surface of plane map assigned address, and the sensing touch point connects voice playing device, makes the switch of voice playing device.
Aforesaid electronic speech map, described voice playing device is: voice IC integrated chip 9 links to each other with touch point 15 with D/A conversion circuit 17 by oscillatory circuit 16, D/A conversion circuit 17 is connected with audio amplifier circuit 12 and dynamic loudspeaker 11 through tone frequency channel wire 14, audio amplifier circuit connection connecting to neutral device 13 links to each other with power supply tie-in line 18 with electric power connection line 10, and voice IC integrated chip 9 links to each other with power supply tie-in line 18.
During use, turn on the power switch, with pointing directly touch or scheming surperficial assigned address in the sensing, voice system is just play voice because of induction or touch conducting.
Compared with prior art, advantage of the present utility model is and can not only sees, and by touching sounding, can listen, therefore can improve people's use interest, the while, structure was small and exquisite, is easy to carry owing to the utility model simplicity of design.
