Embodiment Construction

[0018] A keyboard signal processing system configured for high-quality voice playback according to the present invention will be further described in detail through specific embodiments below.

[0019] Such as figure 1 and figure 2 Shown, a kind of keyboard signal processing system that configures high-quality voice playback, comprising:

[0020] The signal input connector 1 adopts an FPC connector and is connected with the touch signal processing circuit 2 for inputting the touch signal into the touch signal processing circuit 2. The signal size and sensitivity are determined by the capacitance of the touch keyboard and the size of the parallel capacitance Decision, because the capacitance values ​​of different touch keyboards are different, so the parallel capacitance parameters are also different;

[0021] The touch signal processing circuit 2 is composed of an integrated chip TS04 and its peripheral components (resistance, capacitance), which is connected with the conve...

Abstract

The invention relates to a keyboard signal processing system configured with high-quality voice playing. A signal input connector and a touch signal processing circuit can convert touch signals into control signals which are then converted into keyboard signals through a conversion circuit to control a voice circuit to produce voice, a microprocessor can send a command to control the voice circuit as well, and the system can assist or replace a simple display. The problem that electronic equipment is inconvenient for man-machine communication and weak-eyed people cannot operate the electronic equipment conveniently are solved, peripheral circuit components are few, area of a circuit board is greatly decreased, a chip can directly drive a loudspeaker, no external power amplifier circuit is required, and the keyboard signal processing system is low in production cost, small in size, high in reliability, wide in application range and applicable to various electronic equipment, handheld equipment and household appliances.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a keyboard signal processing system equipped with high-quality voice playback. Background technique [0002] At present, the artificial control of electronic products mainly comes from hard keyboards, soft keyboards or relatively novel touch keyboards. However, it is often inconvenient to operate the keyboard in operation, especially for people with poor eyesight and in some specific occasions. The markings on some keyboards will be worn out due to long-term use, and it is difficult for people who are not familiar with the functions of the keyboard to recognize the functions of the keyboard. General keyboards are relatively easy to cause misuse. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a keyboard signal processing system equipped with high-quality voice prompts, which can solve the problems of in...
