What role can Inductor air core coil play in hearing aids

Inductor air core coil is generally a device installed inside a hearing aid for receiving magnetic signals. When there is an alternating magnetic field in the surrounding environment, the coil can induce this magnetic force, thereby generating a current, which can finally be converted into sound after being subjected to the microphone. So as to pass to the human ear.

So how do these Inductor air core coils work? In fact, when the hearing aid is in the microphone, the coil actually does not work; and when the hearing aid is in the inductive coil, the coil can recognize the magnetic signal in the surrounding environment, and can also amplify it into an electrical signal of the same size, which can be further transformed into Recognized voice. The stronger the magnetic signal, the clearer and truer the sound you hear.

So which hearing aids have Inductor air core coil function? BTE hearing aids, such hearing aids are generally large in size, easy to operate, and easy to install inductive coils. What functions can inductive coils generally achieve?

Answer the call, the microphone program Hearing aid microphone works normally, can collect the sound in the surrounding environment. There is also the induction loop magnetic signal. The Inductor air core coil system can generally convert the audio signal into an electric current, which in turn generates a magnetic field for identification by the inductive coil in the hearing aid. So when the inductive coil in the hearing aid recognizes this magnetic signal, the inductive coil can convert it into sound and transmit it to the human ear through the receiver. The relatively few signal conversion times of the inductive coil make the sound distortion less, the signal-to-noise ratio greater, and listening more comfortable.

Since the lcd video brochure everyone can speak for themselves

An important part of socializing people in the workplace is the exchange of business cards. The lcd video brochure is no longer a rare thing. The business card exchange method has become more and more high-end. Now there is a lcd video brochure to introduce yourself.

The use of video as an entry point is indeed relatively new in the current market. In terms of recruitment, many HRs will feel very researched after facing the traditional electronic resume and paper resume for a long time, but if it is a video card to introduce themselves It will be very novel, which will impress the other party.

lcd video brochure can be used not only in work and business, but also in blind date. For the introduction link before, the video business card with sound image will obviously make people leave a better impression. There are many development scenarios.

What are the advantages of rfid tracking tags?

Compared with traditional bar code technology, rfid tracking tags save more time manpower and material resources, and can improve work efficiency. RFID can quickly scan. RFID readers can generally recognize and read several rfid tracking tags at the same time.

Small size and diversified shapes. RFID is not limited by size and shape in reading, and does not need to match the fixed size and printing quality of paper for reading accuracy. Therefore, RFID tags can generally be miniaturized and diversified, so that they can be applied to different products.

Anti-pollution ability and durability. Generally, the traditional barcode carrier is paper, so it is more susceptible to pollution, but RFID is very resistant to substances such as water, oil, and chemicals. In addition, because the bar code is attached to a plastic bag or an outer carton, it is particularly vulnerable to damage; RFID tags store data in the chip, which is to prevent contamination.

This label can also be reused. Today's barcodes cannot be changed after they are printed. RFID tags can be repeatedly added, modified, and deleted data stored in RFID tags to facilitate the update of information.

Can be penetrated and barrier-free reading. In the case of being covered, RFID can penetrate non-metallic or non-transparent materials such as paper, wood and plastic, and can communicate penetratingly. The barcode scanner can read the barcode only when it is close and there is no object blocking.

The memory capacity of the data is large. The capacity of one-dimensional bar code is 50Bytes, stability, RFID carries electronic information, and its data content can be protected by password, so the related content is not easy to be forged and altered.

RFID has attracted much attention because of its long-distance reading and high storage capacity. Therefore, it can not only help an enterprise greatly improve the efficiency of goods and information management, but also allow sales and manufacturing companies to be interconnected to receive feedback information more accurately, control demand information, and optimize the entire supply chain.

What is the specific function of Pneumatic Quick Couplings?

Pneumatic Quick Couplings are mainly used for air piping and pneumatic tools. They can be used to connect or disconnect pipes without tools. When not connected-when the ferrule of the mother body is moved to the other end, stainless steel The bead automatically rolls outward, and the child body is disconnected by the action of the spring force of the valve of the mother and the child, and the valves of the child and the mother will be closed separately, blocking the fluid flow in an instant.

Quick couplings are generally suitable for the connection of pneumatic pipelines, compressed air, and nitrogen. The pipelines can generally be placed in working positions that are often loaded and unloaded, such as the operation of pneumatic tools in the assembly line, and of course can also be used for hydraulic machines, chemical and marine piping Wait.

WHEN DECORATING THE TV CABINET YOU NEED TO PAY ATTENTION TO THE FOLLOWING ASPECTS TO BE BEAUTIFUL

TV cabinet manufacturers generally believe that quality is actually the user's first requirement, but it is no exception for TV cabinets. The composition of product quality generally depends on many aspects.

The first is a reasonable design, but also for the quality of the market today, consumers are very concerned about design when buying, including convenience, beauty and practicality in use, which are related to design. In terms of selection, one needs to consider the reliability of the materials of the brand manufacturers, and then also depends on the price in the selection.

But in terms of design, generally speaking, it will be greatly affected by the design strength and design concept of the manufacturer. The style of the TV cabinet produced by each manufacturer is very different. However, there are also some manufacturers whose design concepts are relatively trendy. However, the products also have unique innovations, so not many are recognized by users because of strength and philosophy. But precisely because of the quality, high-quality materials, will have a great influence on the final product price. Generally, good materials will increase the price relatively.

In addition to the design, another element is the material. This is already used in the production of this TV cabinet. The materials used are very different. Some companies use advanced materials, but some companies The materials used have no advantages, so users need to pay attention to their choices.

Another point is workmanship. In fact, the workmanship of a TV cabinet is related to quality, grade, service life, etc. When it comes to workmanship, there are two requirements. One is the production strength of the manufacturer, and the other is in production. Sense of responsibility. If one aspect is not achieved, it will have a great impact on workmanship. So under normal circumstances, the products with high workmanship, either the manufacturer has the strength, or the manufacturer has a high sense of responsibility
