KT148A Voice Chip: Analysis of Voice Application in Electronic Sphygmomanometers

The voice - enabled electronic sphygmomanometer, with its voice - prompt function, offers voice announcements throughout the entire process from pre - measurement to the presentation of measurement results. This provides great convenience for the elderly and those with poor eyesight. The voice chips and Bluetooth chips of Qingyue Electronics are widely used in fields such as electronic medical devices, medical auxiliary equipment, physical health index monitoring, and various measuring instruments. They provide professional voice chip and Bluetooth technology development services to manufacturers of equipment such as electronic sphygmomanometers, blood glucose meters, and body fat scales.

Design Principle of the Voice Chip Solution for electronic SphygmomanometersCircuit Connection and Signal Flow

The electronic sphygmomanometer circuit is connected to the voice circuit, and the voice circuit is connected to the speaker. The data signal generated by the electronic sphygmomanometer circuit is transmitted to the voice circuit. This signal not only serves as an input but also controls the voice circuit to generate an audio signal, which is finally output as sound by the speaker.

The Coordination Mechanism of Voice and Address Code

Different voices are set within the voice circuit, each corresponding to a specific address code. The electronic sphygmomanometer circuit has an in - built address - code data generation circuit and a comparison circuit. The voice circuit is connected to the electronic sphygmomanometer through serial data lines, data feedback lines, and data confirmation lines. Through this connection, the voice - enabled electronic sphygmomanometer can report the real - time measured blood pressure value in a voice - based manner.

Application Practice of KT148A Voice Chip in electronic SphygmomanometersThe Implementation Architecture of Voice Function

The KT148A voice chip is selected to achieve the voice - playing function of the electronic sphygmomanometer. This chip pre - records human - friendly voices, is responsible for storing and outputting voice information, while the speaker is tasked with outputting audio voices.

The Process of Data Processing and Voice Output

The single - chip microcomputer obtains digital blood - pressure data from the electronic sphygmomanometer according to the control information. After data processing, it controls the voice chip to output the corresponding human - friendly voices to the speaker.

Product Features of KT148A Voice Chip

The KT148A voice chip adopts the SOP8 surface - mount package form. It has the capabilities of anti - interference and shock - resistance. With superior performance, high reliability, beautiful sound quality, and good stability, it has been widely used in the market, enabling users to select according to product requirements.
