The device mainly comprises the following parts: sound identifying tool software, microphone, sound signal filter, amplifying circuit and gaining control circuit, coded circuit and drive program, coded circuit and computer interface circuit and matched soft package. This invention fully uses PC materials and realizes the sound browse, inquiring and control functions through combination with the multi-medium software development tools.

Description

technical field [0001] The invention relates to an electronic device used for voice interaction by a voice information query system, in particular to the transformation and product upgrade of the original information query product (touch screen). At the same time, it can also be installed on a personal computer as an external device to realize the voice control function and enhance the operability of the computer. Background technique [0002] The information query system as a dedicated interactive platform mainly achieves the purpose of information query by the user tapping a specific information area on the touch screen with a finger. It is mainly composed of computer host, display screen, touch screen, USB interface sound processing and encryption board, audio power amplifier, cabinet, speaker, power supply and other parts. [0003] The original touch screen information query system mainly has the following problems: [0004] (1) In use, the touch screen that has the ab...

AI Technical Summary

Problems solved by technology

However, due to the structure and material limitations of the touch screen itself, positioning drift often occurs, resulting in a deviation or even mismatch between the display area and the original corresponding touch area, which brings great trouble to normal use.

In order to make up for the above shortcomings, the display and the corresponding touch area must be made as large as possible to increase the effectiveness of the click, but it is obvious that the amount of optional information on each page is reduced; moreover, regular corrections are required position

[0005] (2) During use, due to non-subjective reasons such as pollution by finger attachments and natural aging, regular maintenance is required in frequently touched areas, which undoubtedly greatly increases the maintenance workload of users

[0006] (3) The original touch and use method is not hygienic enough

[0007] To sum up, the efficiency of information query is not high, which will inevitably lead to an increase in the complexity of use. In addition to considerations such as hygiene, it is bound to cause resistance to the user.

However, the original products have higher requirements for maintenance work, which also increases maintenance costs.

These unfavorable factors have hindered the development and promotion of the original touch screen system to a certain extent.
