Abstract
The utility model relates to a human body sensing automatic advertisement pictographic sounder, comprising a pictographic molding shell and an electronic device which is arranged in the pictographic molding shell. The function of sound amplification and shout with voice change are completed by an electronic circuit which is composed of a human body sensing signal control circuit, a solid voice recording and reproducing circuit, a voice change circuit, an audio preamplification circuit, an audio power amplification circuit and a frequency-division typed loudspeaker system which are connected in series. Brief lingual automatic play can be carried out dramatically. The utility model adopts a novel human body sensing device and a digital solid language recording and reproducing circuit and is particularly suitable for public places of emporiums, hotels, restaurants, recreation, etc.
Description
The utility model relates to acoustics, relates in particular to a kind of automatic advertisement pictograph of human sensing sound equipment that the pictograph shell is arranged, can carry out speech advertising automatically.
At present, the pictograph moulding that the various materials that the management place is provided with are made (as animation animal and human thing etc.), and the stereo set of these places uses, have only single vision or auditory effect, and the repeat playing of brief statement is made in stereo set inconvenience, because their function singlenesses, the sales promotion function of management place also just is restricted, unsatisfactory.
The purpose of this utility model is exactly to overcome above-mentioned weak point to propose a kind of automatic advertisement pictograph of human sensing sound equipment that integrates moulding and sound equipment.
Technical solution of the present utility model is as follows:
The automatic advertisement pictograph of human sensing sound equipment is pictograph moulding (as ugly duckling, sesame official rank) and be contained in combining of its inner electronic installation.The electronic installation of pictograph enclosure is become by the human sensing signal control circuit of belt sensor and operational amplifier, solid-state audio record circuit, change of voice circuit, audio frequency pre-amplification circuit, audio power amplifying circuit and the system-level joint group of frequency-dividing loudspeaker.
The utility model not only has active image appearance to use as public address equipment, and it is handsome in appearance, can be sent that humorous language carries out advertising and the change of voice is propagandaed directed to communicate by human sensing automatically.Vivo finish distribution, shopping guide, guide, warning, ceremony, greet, amuse etc.The utility model adopts novel human sensing device and digital solid-state language playback circuitry, and higher utility is arranged.Being particularly suitable for public places such as market, hotel, hotel, amusement uses.
Accompanying drawing is a circuit diagram of the present utility model.
Below in conjunction with embodiment and contrast accompanying drawing the utility model is made detailed description.
The automatic advertisement pictograph of embodiment human sensing sound equipment, comprise pictograph moulding shell and be contained in its inner electronic installation, electronic installation is made up of belt sensor (CGQ) and the human sensing signal control circuit of operational amplifier (1IC), solid-state audio record circuit (2IC), change of voice circuit (3IC), audio frequency pre-amplification circuit (4IC), audio power amplifying circuit (5IC) and frequency-dividing loudspeaker system (Y) cascade.The detected human body signal of sensor (CGQ), undertaken triggering solid-state audio record circuit (2IC) after the processing and amplifying by operational amplifier (1IC), for making the language tone color meet modeling characteristic, voice signal will be by change of voice circuit (3IC), amplify by the preposition amplification path of audio frequency (4ICb) again, input audio power amplifying circuit (5IC) promotes frequency-dividing loudspeaker system (Y) at last and plays.External sound source can be imported another audio frequency pre-amplification circuit (4ICa) by input end (IN).Switch (K2) can carry out the selection of the language broadcast and the function of propagandaing directed to communicate.
Present embodiment is decorated the management place with the pictograph shell and is attracted client, and inner altogether electronic installation can amplify to external sound source such as compact disc player, sound-track engraving apparatuss.When the pedestrian of dealing walks close to, the brief statement of prerecording in the internal circuit can be play automatically according to the selected tone color of moulding image, external sound source this moment music as a setting then.
