Description

M247176 V. Description of planing (1) < Technical field of new type > This creation is about electronic noise that can exceed unnecessary noise |, Enhancement: J sound device, especially refers to-a kind of digital conversion and Those who have reached the standard of convenience and can pass the fetal sound through the "previous technology", "," and "preservation of the stethoscope structure". Commonly known stethoscope, i, a shallow dish can be set in the opening: Twenty-one has an opening, a hollow container, and a membrane, so that the resonance membrane can slightly protrude = a peripheral edge of the resonance inner lid is set above the far inner lid, and the top side of the arc surface of the inner lid is tight; Combining the interior with the inside of the stethoscope, two dimples are used to connect the resonance membrane to the human ear: use the sun to capture the resonance membrane to make the resonance membrane vibrate, and then: the ::: Occupy the detection site, use the sound gas to pass the catheter through the catheter to the diaphragm of the stethoscope. The diaphragm in the stethoscope is vibrated to generate the movement of the simulated sound source to the human ear and vibrate the ear.

A However, the structure of the stethoscope mentioned above should be due to the resonance of the stethoscope ’s resonance membrane. The column is missing: The periphery of the withdrawal gorge is directly folded back, but the folds and deformation are easy to occur at the folded position. produce. The fit ’response to the vibration of the sound source

B Although a general stethoscope can be straight to a certain extent, it is also susceptible to the interference of environmental dry sounds. ^ ^ 22 Your voice, the difficulty of diagnosis and the reduction of accuracy. Dude > g will increase

C Although the analog sound signals picked up by traditional stethoscopes can be passed, they can benefit from the analog sound signals. Spears, stomach protection, etc., are determined by digital instruments,

ill, page 6 M247176 V. Creation Instructions (2) The application of judgment, which can only be compared with human ears, lacks scientific basis. In view of the above-mentioned shortcomings of the conventional stethoscope structure, the author researched and improved some of the shortcomings of txuan, and finally created this creation. < New content > The purpose of this creation is to provide an electronic tire sound listening device, which mainly uses a microphone to pick up the tire sound signal detected by the stethoscope body, filters the noise through an audio processing circuit, and amplifies it. An analog / digital converter converts analog audio signals into digital signals and inputs them to the microprocessor. The microprocessor can choose to control the display device to output related images or store them in memory. It can not only convert the fetal sound data into digital signals. Stored for reference, the digital signal can also be transmitted to the far end, and then the digital signal is converted into an analog sound signal by a digital / analog converter. After being appropriately amplified by an amplifier, the fetal sound is output by Lao Ba for easy remote Auscultation or consultation, this is the main purpose of the creation. This type of electronic tire sound listening device created according to the present invention is provided with a ring flange on the inner ring of the periphery of the stethoscope body, and the ring flange protrudes from the plane of the periphery of the stethoscope body, and the ring flange is used to support it. The resonance film can be made flatter and tighter, and the relative vibration can be more faithfully reflected by the environmental sound, which is another purpose of this creation. This type of electronic fetal sound listening device created according to this article can output the sound directly through a speaker after being processed by the audio processing circuit for on-site auscultation, or directly record and store the analog fetal sound signal through a recording interface. In order to improve the convenience of its application, this is another purpose of this creation.
