Claims

[Scope of utility model registration request]

A sound sensor that receives sound waves emitted from the object to be measured and converts them into analog signals, an A/D converter that receives the analog signals output from the sound sensor and converts them into digital signals, and a sound wave generated from the object to be measured. A memory for storing data and reference data for comparison with the generated data; a signal input section for outputting a function selected by manual operation;
A calculation unit that compares and calculates the output signal from the /D conversion unit and necessary reference data output from the memory according to a command from the signal input unit, and a calculation result output from this calculation unit is sent to a first drive circuit. An auscultation device that includes a speaker that outputs audio using a second drive circuit, and a display section that displays an image using a second drive circuit.
