Description

Shock-absorbing structure

This creation is about a structure, especially a shock-absorbing structure.

The traditional microphone is called Mai, also known as a microphone or a microphone. The official Chinese name is microphone. Translated from the English microphone, the vibration of the sound is transmitted to the diaphragm of the microphone, which drives the magnet inside to form a changing current. The current is sent to the subsequent sound processing circuit for amplification. Therefore, from the above, it can be known that the microphone is a signal that converts the sound waves of speech, singing, or musical instrument performance, which is commonly known as vibration, into electricity in various ways.

Microphone types can be divided into the following types: Dynamic Microphones, which include coils, diaphragms, and permanent magnets. Because they contain coils and magnets, they are not as lightweight as condenser microphones, with low sensitivity and high and low frequencies. The response is poor. The advantage is that the sound is soft and suitable for recording human voice. The condenser microphone (Condenser Microphone) does not have a coil and a magnet. It changes the voltage by changing the distance between the two diaphragms of the capacitor. The condenser microphone is commonly used because of its high sensitivity For high-quality recording; the electret condenser microphone (Electret Condenser Microphone) uses an electret substance that can retain a permanent charge, so there is no need to power the capacitor. However, general electret microphone components have built-in electronic circuits to amplify signals, so they still need to be powered by low voltage (normal voltage is 1.0V-10V). Such microphones are currently widely used in consumer electronics; micro-electromechanical microphones ( MEMS Microphone refers to a microphone made using MEMS (MicroElectrical-Mechanical System) technology. It is also called a microphone chip or a silicon microphone. MEMS microphones are mainly used in some mobile phones, PDAs, etc. Small mobile products. Almost all such small microphones used in the past are electret condenser microphones. Ribbon microphones (Ribbon Microphones) Wavy metal foil strips, usually aluminum, are placed between the two poles of the magnet. Inductive signals are mainly used in professional recording studios due to their large shape and the fragility of aluminum foil strips. Carbon Microphones have been used extensively as carbon microphones in old telephones, and are now rarely used.

The microphone is used to collect air vibrations. Such a signal will not be a very powerful signal. However, the long range of this signal will cause attenuation. In addition to the air, there are various "radio waves", such as radio waves from base stations, and wireless from WIFI. Signals ... wait, when the signal is weak and the distance is long, the received signal becomes weaker. At this time, various signals generated in the air will form various interference noises in the microphone.

When the signal generated by the radio waves will cause noise to the microphone, if the microphone is installed inside the main body case, when the main body is operating, the main body case will cause vibration due to the internal operation, so this vibration will cause the inside of the main body. Small sounds. At this time, turning on the microphone will receive these small sounds and generate noise.

In addition, in addition to the above-mentioned radio waves in the air, the microphone may receive unwanted noise and noise generated during operation, there is another condition that may also cause the microphone to generate noise because of the poor contact caused by the microphone itself. For example, the microphone lead is broken or the wire is oxidized. However, the problem of poor microphone contact can be solved by simply replacing the wire. Therefore, the main focus is on the suppression of "radio interference".

Most of the existing methods for microphone noise suppression are electronically digitally suppressing noise, such as through program adjustments to suppress microphone noise, cancel sound resonance, enhance the microphone, and eliminate level shifts. Noise is also collected, but this method can only eliminate radio noise generated by various electronic signals, but it cannot eliminate environmental noise caused by the structure.

In order to solve the above-mentioned problem of environmental noise caused by structural vibrations, this creation provides a structure that seals the microphone through silicone to produce an air-tight structure, so that the sound of the external environment is isolated by the air-tight structure, so that the microphone will not receive the external environment. Noise caused by vibration.

In addition, this creation can also use electronic methods to suppress electronic noise. In combination with the air-tight structure described above, the microphone will not receive electronic noise generated by electronic signals when used. Through the structure of this creation, it can also be avoided. When the microphone receiver is installed in a closed structure, the ambient sound generated by the vibration enables the microphone to smoothly receive the main sound effect during operation, avoiding noise reception at the same time.

Based on the above, it can be known that this creation is to provide a shock-absorbing structure through which the microphone will not receive vibration noise in the environment when recording or receiving sound effects in a closed environment, so that the main recorded sound effects are clearly presented.

One of the purposes of this creation is to provide a structure that can cover the microphone so that the microphone will not be affected by the sound of the external environment when receiving the sound effect.

For the above purpose, the present invention provides a shock-absorbing structure, which is fixed in a device.

In order to make the reviewing committee members have a better understanding and understanding of the characteristics of this creation and the effects achieved, I would like to provide better examples and detailed descriptions with the following description:

When the traditional microphone is receiving radio, it is easy to receive electronic noise generated by external environmental sounds or electronic signals. As a result of listening to the recording results, it is found that the main sound effects also include electronic signal noise or environmental sounds. Signal noise can be removed by firmware or software. However, external environmental vibration noise cannot be eliminated by firmware or software.

When the microphone is fixed in a device, it can pass the shock absorbing. The component and the buffering component cancel the vibration formed by the environment, so that the microphone will not receive the sound effect generated by the vibration when the radio is received.

Through conventional techniques, it can be clearly known that when the sound receiving element 16 is placed in a computer case or a speaker case, it is usually directly fixed, and there is no special structural design for the sound receiving element 16. As a result, after learning that the radio program is completed, many small noises will be heard when the recorded sound is played back. These noises also include the sound of the chassis vibration, the sound of the speaker resonance, or the noise generated by the case itself. Because of this, the design of the sound-absorbing element 16 is designed for a shock-absorbing structure.

As mentioned above, the materials used in the creation of the damping elements 13 and the cushioning element 162 may be silicone or rubber. The following explains the principle of damping and sound absorption with rubber materials. These damping elements 13 are made of rubber. The characteristics of the material are used for shock absorption and sound absorption. Rubber is a material with high elasticity and high viscosity. The elasticity of rubber is caused by the change of the conformation of the curled molecule. The interaction between the rubber molecules will hinder the movement of the molecular chain. It also exhibits viscosity characteristics, so that stress and strain are often in an unbalanced state. The curled long-chain molecular structure of rubber and the weak secondary force between the molecules make the rubber material exhibit unique viscoelastic properties and therefore have good shock absorption, sound insulation and cushioning properties. Rubber is widely used to isolate vibration The shock absorption and shock absorption are also due to the characteristics of rubber with hysteresis, damping and reversible large deformation. The hysteresis and internal friction characteristics of rubber are usually expressed by a loss factor. The more obvious, and because of this, the shock-absorbing structure 1 of this creation can produce the effects of shock absorption and sound insulation.

In the embodiment described above, the method of the present invention provides a shock-absorbing structure through which the microphone does not receive vibration noise in the environment when recording or receiving sound effects in a closed environment, so that the received sound effects are clearly presented.
