Abstract

The utility model discloses a sound publicity object which comprises a publicity object, and is characterized in that the publicity object is provided with a sound ship, wherein the sound chip is electrically connected with a horn. According to the embodiment of the utility model, the sound chip adopts a WT588D integrated circuit, the power supply end of the sound chip is connected with a power supply, the PWM (Pulse-width Modulation) audio output end of the sound chip is connected with the horn, a trigger port of the sound chip is connected with one end of a normally-open touch key switch, and the other end of the normally-open touch key switch is grounded. The sound publicity object has the beneficial effects that sound and music are built in the sound chip, and can be broadcasted through the horn, so that people can see the texts and pictures on a traditional print media, and simultaneously can hear the sound information relevant to the texts and pictures, so that the attention of people can be attracted, and the impression and understanding of people on the publicity content can be greatly deepened, and then better publicity effect can be obtained. According to own needs, people can control whether the publicity object sounds or not by the normally-open touch key switch.

Description

Sound propaganda thing

Technical field

The utility model relates to a kind of propaganda thing, is specifically related to a kind of sound propaganda thing.

Background technology

At present, known print media all is a static materials, mainly transmit information to masses by single visual manners such as literal, pictures, but, most content is the reading interest to cause that people are strong not, people often read down with regard to out of patience continuation after having seen title, and not deep for the impression of institute's reading content, and a lot of contents can not obtain the cognition degree and the level of understanding at once.

Summary of the invention

The purpose of this utility model provides a kind of sound propaganda thing, can transmit information to masses by enough sound, thereby attracts popular attention.

To achieve these goals, the technical solution of the utility model is: a kind of sound propaganda thing, comprise the propaganda thing, and it is characterized in that this propaganda thing is provided with a speech chip, this speech chip is connected with loudspeaker.According to an embodiment of the present utility model, this speech chip adopts the WT588D integrated circuit, the power end of this speech chip is connected with power supply, the PWM audio output of speech chip is connected with loudspeaker, the triggering mouth of speech chip is connected with an end of often driving the touching switch, often opens the other end ground connection of touching switch.

The beneficial effects of the utility model are, in built-in voice of speech chip and music, play back by loudspeaker, feasible masses can be when seeing conventional planar medium literal and picture, hear associated acoustic information, attract the public concern degree, and can deepen impression and the comprehension of spectators greatly, obtain better the effect of publicity this promotional content.Often driving the touching switch can be so that masses can control whether sounding of this propaganda thing as required.
