In one embodiment, the external electronic device may be a portable device such as a mobile phone, a tablet computer, a notebook computer, and a wearable device.

The data processing module 60 is configured to receive the electrical signal and process the electrical signal to obtain the waveform, amplitude and respiratory frequency of the sound emitted by the subject to be auscultated, and the processed data can be displayed on the display screen of the auscultation apparatus 100 or transmitted to an external electronic device through the communication module 50. The storage module 70 is configured to receive and store the electrical signals, and further to store data processed by the data processing module 60 for use in application scenarios such as remote diagnosis or teaching, and the communication module 50 can also transmit the data stored in the storage module 70 to an external electronic device.

The communication mode of the communication module 50 includes, but is not limited to, Zigbee, bluetooth, Wi-Fi, mobile communication, and the like. For example, a USB interface may be provided on the auscultation device 100 to communicate via data line transmission, or a bluetooth module may be integrated on the circuit board to communicate via wireless bluetooth. The data processing module 60 includes a comparator and a processor, both mounted on the circuit board 41. The comparator may be one of single-way comparators MAX9060, MAX9061, MAX9062, MAX9063, and MAX9064, and the processor may be a Central Processing Unit (CPU), a Micro Control Unit (MCU), or the like. The memory module 70 may include readable media in the form of volatile memory elements, such as a random access memory element RAM and/or a cache memory element, and may further include a read-only memory element ROM. Memory module 70 may also include a program/utility having a set (at least one) of program modules including, but not limited to: an operating system, one or more application programs, other program modules, and program data, each of which, or some combination thereof, may comprise an implementation of a network environment.

It can be understood that, in a remote diagnosis scenario, a user may send heart sound data acquired by the auscultation device to a remote doctor client, and a doctor may perform remote diagnosis according to a received heart sound electrical signal. In an actual teaching scene, when historical heart sound data is diagnosed and read to summarize experience, the heart sound data stored in the auscultation device can be directly called, and the method is simple and rapid.

It is noted that the terms "comprises" and "comprising," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

The above description is only a part of the embodiments of the present application, and not intended to limit the scope of the present application, and all equivalent devices or equivalent processes performed by the content of the present application and the attached drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
