As shown in fig. 1 to 11, the present invention provides an intelligent stethoscope 101, a body; the audio acquisition module is arranged in the body and positioned at the first end of the body and used for acquiring an audio signal from a user; a processor arranged in the body for filtering the audio signal to retain audio data within a set frequency range; and an audio convergence module adjacent to the audio collection module when connected to the first end of the body for increasing a contact area of the audio collection module with a user, wherein the processor amplifies an audio signal of the audio signal in a range of 20-1,000 Hz when the intelligent stethoscope is operated in an auscultation mode. In fig. 1, a right-side orthogonal view of the intelligent stethoscope 101 shows a first end 104 and a second end 103, and the second end 103 includes an audio acquisition module. The enclosed first housing 102 and the first housing 115 are manufactured to form a pen-type stethoscope design for hand-held operation. A removable protective cover 113, when attached to the stethoscope as shown in fig. 1, is adjacent the distal end of the second end 103 to cover a microphone disposed at the lower end of the stethoscope 101. The control module provides a plurality of user interface controls including: a button 105 for starting and stopping recording of audio data collected by a microphone in the main body audio module; a power switch 111 to physically enable and disable the transfer of electrical energy from the power supply module to the other modules; and buttons 107 and 109 for reducing and increasing the intensity of the audio signal outputted from the main audio module through the audio output jack, respectively. The clamping piece 117 is arranged at the rear side of the stethoscope; which is attached to a plastic housing located above the stethoscope and which is made of a material that is sufficiently resilient so that it can be lifted from a rest position on the back of the stethoscope away from the position closest below the stethoscope to facilitate insertion of paper or fabric (e.g., from a shirt or coat pocket).

Fig. 2 shows an orthogonal view from above of the stethoscope 101, including the proximal end of the clip 117 attached to the upper stethoscope housing. The end cap 119 may be configured to display a brand logo and, in one embodiment, may be configured to cover an appropriately sized compartment area configured to receive one or more removable batteries for providing power to the power module of the body.

Referring to fig. 3, the mode selection button 123 of the control module of the body may be used to select an audio filtering mode for use by the digital signal processor inside the processor of the body. The external interface controller of the control module of the main body includes buttons 125 and 127 for starting and stopping the playing of the sound previously recorded by the audio capture module or the output transmission of the audio data, respectively. The external audio port or jack 128 of the audio acquisition module of the body can accept a standard 3.5mm stereo audio plug for the output and transmission of electronic audio signals. The external data transmission port or jack 130 may accept a standard Universal Serial Bus (USB) plug for the transmission of audio data. The removable boot 129 is in a position separate from the first housing 115. When connected, a protective cover 129 is positioned on the side of the first housing 115 to cover the recessed area containing ports 128 and 130.

Fig. 4 and 5 are bottom orthographic views of the intelligent stethoscope 101. A protective cover 113 is attached to the second end 103 to cover an outer housing 131 surrounding the audio capture module microphone. Tabs on the rear side of the protective cover are adjacent to the surface of the stethoscope 101 to facilitate removal of the protective cover from the outer housing 131. Fig. 5 shows an outer housing 131 having a centrally recessed lower surface profile and centered on the concave microphone. The profile can protect the microphone and guide sound to the microphone.

Fig. 6 shows a side view of the back surface of the clamp 117, as well as user interface control buttons and switches located on the right and left sides of the stethoscope. When the protective cover 113 is attached to the stethoscope, the rear of the protective cover 113 can be seen.

Fig. 7 is an orthogonal front view of the intelligent stethoscope 101, including the external user interface components of two control modules: a touch-sensitive display 133 and control buttons 135. The touch screen 133 may communicate stethoscope status information to the user, such as the current mode of operation, available recorded and stored audio data files, the status of the wireless transceiver within the stethoscope body wireless communication module, and the status of the wireless connection to one or more external wireless receivers. Control buttons 135 enable a user to write from a program to a set of available functions in the subject processor.

Fig. 8 is a side perspective view of the audio convergence module 137. The audio convergence module 137 has a housing formed thereon and is configured to couple the audio convergence module 137 to the smart stethoscope 101 at a position below and adjacent to the outer housing 131. The position where the audio convergence module 137 is connected to the stethoscope 101 is the same as the position where the protective cover 113 is connected to the stethoscope 101, and when the protective cover 101 is attached thereto, the audio convergence module 137 cannot be attached thereto. The outer housing of the audio convergence module 137 includes a tab on the rear side that is adjacent to the rear side of the smart stethoscope 101 when the audio convergence module 137 is connected. This tab facilitates removal of the audio focus 137 from the stethoscope 101. The lower side of the audio convergence module 137 comprises a frame 139 and a support 140, which can hold the vibration film 138 in place. The use of an audio convergence module can improve the good contact of the device with the skin of the patient during auscultation to obtain a stronger audio signal in certain frequency ranges of clinical significance.

Fig. 9 to 11 show a wireless receiver of the intelligent stethoscope. Fig. 9 is an orthogonal front view of the wireless receiver 143, which includes four user interface controls for the wireless receiver control module. The controller includes a power switch 145 for physically enabling and disabling the transfer of power from the wireless receiver power module to other modules. In addition, the buttons 147 and 149 can respectively increase and decrease the signal intensity outputted from the audio module of the wireless receiver through the audio output port or the jack 153, and the audio output port or the jack 153 can receive a standard 3.5mm stereo audio plug for outputting and transmitting the electronic audio signal. The button 151 establishes a connection between the wireless communication module of the wireless receiver 143 and the body wireless communication module of the smart stethoscope 101. The second housing 163 shown in fig. 9 is arranged adjacent to the third housing 165 shown in fig. 10, and the internal components of the wireless receiver are sandwiched therebetween in the form of shells along the peripheral edge thereof. Set screws 155, 157, 159 and 161 secure the housings 163 and 165 together and maintain their peripheral edge alignment. The housings 163 and 165 are designed to have a smooth outer contour for the comfort of the user, particularly when the wireless receiver is not in use and is stored in a pocket or is placed on the user's chest like a pendant on the end of a necklace. Fig. 11 is a top view of the wireless receiver 143, with the external audio port 153 being visible to the naked eye, and so are the perspective views of the four user interface controls 145, 147, 149 and 151.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
