Problems solved by technology

Among them, the airtightness of the auscultation head affects the quality of auscultation. Generally, the existing auscultation head composed of the mutual assembly of the vibrating membrane and the sound collecting head will inevitably have a gap between the vibrating film and the sound collecting head, resulting in poor airtight sealing effect. Good, increase the loss of sound vibration energy and increase the sound attenuation rate, reducing the quality of auscultation

Embodiment 1

[0067] Example 1: Planar diaphragm

[0068] The steps include: using a planar diaphragm with a thickness of 0.175 mm to 0.178 mm and made of polycarbonate, spraying silica gel (i.e. a soft material) on the first surface of the diaphragm, and curing the soft material to A soft structural layer is formed with a thickness of 0.042 mm to 0.045 mm. The above steps are completed to obtain a vibrating membrane with a thickness of 0.22 mm; the vibrating membrane is fastened and clamped to the sound collecting head of the stethoscope through a holding ring.

Embodiment 2

[0069] Embodiment 2: Vibrating membrane with holding part

[0070] The steps include: using a diaphragm with a thickness of 0.175mm to 0.178mm and made of polycarbonate, the diaphragm is preformed and stamped to form a semi-finished product of the vibrating membrane with a holding part, and the silica gel (that is, a soft material) ) is sprayed on the first surface of the semi-finished vibration part with the holding part, and the soft material is solidified and molded to form a soft structural layer with a thickness of 0.042 mm to 0.045 mm. Complete the above steps to obtain a vibrating membrane with a holding part and an overall thickness of 0.22 mm; a sound collecting head that can be directly combined and fixed to a stethoscope.

Abstract

The invention relates to a vibrating membrane, a method of manufacturing the vibrating membrane, and a stethoscope applied to the vibrating membrane. The invention relates to a vibrating membrane having a flat vibrating portion, wherein the vibrating portion is provided with a first surface; the structure of the vibrating membrane further includes a soft structural layer disposed on the first surface. When the vibrating membrane is combined with a sound collecting head, the soft structural layer is in contact with the sound collecting head to enhance the airtightness of the vibrating membraneand the sound collecting head, so as to prevent the acoustic vibration energy from being lost. The invention also relates to a method of manufacturing the vibrating membrane, which can quickly producea large number of vibrating membranes by a simple process.

Description

technical field [0001] The invention relates to a vibrating membrane capable of reducing the loss of sound vibration energy and a stethoscope used therein, especially capable of improving the quality of auscultation. The present invention also relates to a method for preparing the aforementioned vibrating membrane. Background technique [0002] In order to effectively diagnose the health of the patient's internal organs, general medical and nursing staff use a stethoscope to attach to the patient's chest or abdominal cavity, and the sound waves generated by visceral vibrations are transmitted to the ears of the medical staff for diagnosis. Symptoms of cardiopulmonary or gastrointestinal diseases, it is a fast, safe and simple diagnostic tool, and an important portable tool for medical staff. [0003] At present, stethoscopes used by medical and nursing staff can be roughly divided into two types: single-sided stethoscopes and double-sided stethoscopes. No matter single-side...
