[0006] The sound amplification component includes an upper sound amplification part and a transition part located below the sound amplification part, the transition part is fixedly connected to the sound amplification part, and the transition part connects the chest piece with the rubber hose through the sound amplification part;

[0007] The sound amplification part comprises a loudspeaker with an adjustment part, the input end of the loudspeaker is communicated with the input end of the adapter part, and the output end of the loudspeaker is communicated with the output end of the adapter part.

[0008] Furthermore, the adapter includes a cavity and a partition disposed in the cavity, the partition divides the cavity into an input cavity and an output cavity, the input cavity is connected to the input end of the loudspeaker, and the output cavity is connected to the output end of the sound amplification part.

[0009] Furthermore, the sound amplifier also includes a battery for supplying power to the sound amplifier, the positive electrode of the battery is electrically connected to the positive electrode of the sound amplifier, and the negative electrode of the battery is electrically connected to the negative electrode of the loudspeaker.

[0010] Furthermore, it also includes a power monitoring component for detecting the power of the battery.

[0011] Furthermore, the power monitoring component is a power monitoring chip.

[0012] Furthermore, the power monitoring component is an LED light connected in parallel with a loudspeaker.

[0013] Furthermore, the input cavity is connected to a first adapter ring, and the output cavity is connected to a second adapter ring.

[0014] Furthermore, the first adapter ring and the second adapter ring are both made of elastic material.

[0015] The above scheme achieves the following principles and beneficial effects: In the present invention, the sound received by the chest piece is amplified by the sound amplification component to meet the auscultation needs of older medical staff. At the same time, since the loudspeaker with an adjustment component is used, it is convenient for older medical staff to use.

[0021] The following is further described in detail through specific implementation methods:

[0022] The figure marks in the drawings of the specification include: chest piece 11, sound amplification component 12, shell 121, knob 122, loudspeaker 123, first adapter ring 124, shell 125, input cavity 126, partition 127, output cavity 128, second adapter ring 129, hose 13, ear piece 14, power monitoring chip 21, LED light 23.

[0023] The embodiment is basically as shown in the attached Figure 1-2 As shown:

[0024] The present application provides a volume-adjustable stethoscope, which basically comprises a chest piece 11, a sound amplifying component 12, a hose 13 and an ear piece 14, wherein the sound amplifying component 12 is the main improved part of the present application.

[0025] The loudspeaker 12 includes a housing 121 and a loudspeaker 123 installed in the housing 121. The loudspeaker 123 is an existing loudspeaker 123 with an adjustment portion (the adjustment portion is a knob 122 or a button), such as a small loudspeaker 123 of the 707 model, etc. Of course, the loudspeaker 123 used in MP3 can also be used. Therefore, it only needs to be small in size and suitable for use with a traditional stethoscope. The bottom of the housing 121 is provided with a sound inlet and a sound outlet. The input end of the loudspeaker 123 is aligned with the sound inlet, and the output end of the loudspeaker 123 is aligned with the sound outlet. A hollow outer shell 125 is fixed to the bottom of the shell 121 by screws, and a partition 127 is arranged in the outer shell 125. The partition 127 is made of sound insulation material, such as sound insulation cotton, etc. The partition 127 divides the outer shell 125 into an input cavity 126 and an output cavity 128. The input cavity 126 is connected to the sound inlet, and the output cavity 128 is connected to the sound outlet. At the same time, the input cavity 126 is connected to the first adapter ring 124, and the output cavity 128 is connected to the second adapter ring 129. The first adapter ring 124 and the second adapter ring 129 are both made of elastic material, such as medical silicone material, etc.

[0026] In this embodiment, the chest piece 11 is connected to the input cavity 126 through the first adapter ring 124 , and the rubber tube 13 is connected to the rubber tube 13 through the second adapter ring 129 .

[0027] Thus: the sound received by the chest piece 11 passes through the first adapter ring 124 and the input cavity 126, and is transmitted to the input end of the loudspeaker 123 through the sound inlet, amplified by the loudspeaker 123 (of course there is a speaker), and then output to the output cavity 128 through the output end of the loudspeaker 123, and then to the hose 13 and the ear piece 14 through the output cavity 128, so that the elderly medical staff can perform auscultation. In this process, the volume of the sound can be adjusted by the knob 122 to select the volume suitable for the elderly medical staff.

[0028] The chest piece 11 and the hose 13 of the present application are connected by the first adapter ring 124 and the second adapter ring 129, and because the first adapter ring 124 and the second adapter ring 129 are both made of elastic materials, the chest piece 11, the hose 13 and the ear piece 14 can be removed from the sound amplifier component 12, and can be disinfected. Since they can be removed, they can be disassembled and stored, which reduces the overall volume and is convenient to carry. Of course, the loudspeaker 123 is installed in the shell 121, so the shell 121 and the outer shell 125 can also be made of medical grade materials, and the surfaces of the shell 121 and the outer shell 125 are disinfected. Of course, it is also necessary to prevent the disinfectant from entering the outer shell 125 and the shell 121 when using the disinfectant.

[0029] Another embodiment of the present application, in combination with the attached Figure 3 As shown, the loudspeaker 123 is electrically connected to the battery, specifically, the positive electrode of the battery is electrically connected to the positive electrode of the loudspeaker 123, and the negative electrode of the loudspeaker 123 is electrically connected to the negative electrode of the battery. The battery is detachably installed in the housing 121 (not shown in the figure), and the battery can be charged and can also supply power to the loudspeaker 123. It also includes a power monitoring component installed in the housing 121, and the power monitoring component is an existing power monitoring chip 21. The input end of the power monitoring chip 21 is electrically connected to the positive electrode of the battery, and the output end of the power monitoring chip 21 is electrically connected to the positive electrode of the loudspeaker 123. The power monitoring chip 21 is electrically connected to a display light. After detection by the power monitoring chip 21, the display light can be used to give a power alarm to the battery. Specifically, if the display light becomes dim, it means that the battery is insufficient (the battery is removed for charging at this time), otherwise the battery is sufficient.

[0030] Another embodiment of the present application, in combination with the attached Figure 4 As shown, the loudspeaker 123 is electrically connected to the battery, specifically, the positive electrode of the battery is electrically connected to the positive electrode of the loudspeaker 123, and the negative electrode of the loudspeaker 123 is electrically connected to the negative electrode of the battery. The battery is detachably installed in the shell 121 (not shown in the figure). The battery can be charged and can also supply power to the loudspeaker 123. It also includes a power monitoring component installed in the shell 121. The power monitoring component is an LED lamp 23. The LED lamp 23 is connected in parallel to the power supply circuit of the loudspeaker 123. When the battery power is low, the LED lamp 23 becomes dim.

The ordinary technicians in the relevant field know all the common technical knowledge in the technical field of the utility model before the application date or priority date, can obtain all the existing technologies in the field, and have the ability to apply the conventional experimental means before that date. The ordinary technicians in the relevant field can improve and implement this scheme in combination with their own abilities under the enlightenment given by this application. Some typical known structures or known methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for the technicians in this field, without departing from the structure of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, which will not affect the effect of the implementation of the utility model and the practicality of the patent.
