Is the lavalier microphone wired or wireless? Say goodbye to the choice difficulty!

Is the collar clip better wired or wireless? Similar problems can be seen everywhere on Du Niang. Many netizens have launched a heated discussion on this issue, which is comparable to a debate contest. In fact, the question of how to choose between wireless and wired is not only controversial in the microphone field, but also in the headset, audio and other fields. This is an unsolvable problem (at least for the moment)~~What are the advantages of wired and wireless?

Solutions to common problems in the use of wireless microphone

Problems easy to occur 1、 Judgment and solution of channeling (also called channeling). Judgment: There are two reasons for this type of situation,

How to improve the sound quality of general speakers

High-quality decoding chip. Decoding chips are the key to sound quality, and the sound quality displayed by high-quality decoding chips is incomparable to those of poorer ones.

Comparison of bass speakers

Large floor speakers can also see 8-inch 10-inch or even 12-inch low-frequency speakers, but in terms of bass performance, it is always difficult to match the special subwoofer. In addition to the differences in power amplifier equipment, what are the differences in speaker unit and circuit design? The speakers (drivers) used in the subwoofer are designed to work in the lowest frequency range. In structure, they are similar to but different from the bass speaker in the multi-channel speaker. The subwoofer limits the upper limit of the working frequency to about 120-150 Hz, and has a high slope filter (3 to 4 orders)

Speaker selection and layout

(1) Speaker system selection. The speaker system should not only restore the sound with high fidelity, but also consider the recognition degree of the performance group to the speaker, and also consider the subjective evaluation indicators of the speaker, such as the electroacoustic indicators and timbre and sound quality. Meyer Sound active speaker system is selected for this purpose. Meyer Sound active speaker system can also remotely monitor the working status and sound quality of each speaker box through monitoring software and transmission network to ensure that the system is always working. (2) Left, middle and right main loudspeaker systems. The main loudspeaker of the central channel uses a vertical line array speaker system that covers the whole field, and uses the precise vertical finger of the line array

Is the principle of loudspeaker electromagnetic induction?

Electromagnetic induction is another energy conversion method based on Faraday's electromagnetic induction and Lenz's law. The "Lenz's Law" mentioned here means that the magnetic field that generates the induced current will always prevent the magnetic flux that generates the induced current from changing. In other words, to obtain an energy, we must overcome the current brought by the current, and to convert energy into electrical energy, we need external energy. In junior high school physics, we learned the "right hand rule" to judge the direction of the induced current in the wire, that is, the right hand is extended horizontally, so that the thumb and the other four fingers are vertical, and at the same level as the palm. Place the right hand in the magnetic field. If the magnetic force line is facing the palm (when the magnetic induction line is a straight line, the palm of the palm is N electrodes), and the direction pointed by the thumb is the direction of the induced current on the wire. Speakers, also known as "speakers", are a kind of "energy conversion device" that converts electrical signals into acoustic signals. There are many kinds of speakers, such as internal speakers and external speakers, and their sizes are also different.

Classification of speakers

There are many kinds of speakers. We can classify them in three ways. They are classified according to the driving mode, the shape of the paper basin or radiator, and the purpose. 1. According to the driving mode, it is how to apply the electrical signal to the paper basin to convert it into mechanical force and then generate vibration. See the following table: 2. Classification according to the shape of diaphragm or radiator According to the shape of the diaphragm or radiation, there are mainly conical, flat, spherical, trumpet, ribbon, and sheet shapes. Conical diaphragm speaker: When we talk about speakers, we will think of conical diaphragm speaker (also called paper basin speaker), which is a widely used speaker type at present. Especially as the bass speaker of high fidelity speaker system, high fidelity means to maintain its authenticity. We usually see HiFi audio, which means high fidelity. Conical diaphragm loudspeaker means that its drum paper is conical. In our specifications, we often see that the type is CONE, which means cone. We often call the drum paper CONE PAPER, which means that the paper body is conical.

Smart speakers with screen become a new trend in the market

MediaTek MT8516 is the main voice in the smart speaker market. It is equipped with a quad-core CPU, integrated Wi-Fi and Bluetooth, and the built-in PowerAQ audio correction tool can provide better sound quality.

Is IoT nothing more than a sophisticated espionage network?

How the Internet of Things affects privacy has always been a matter of concern. Smart speakers, for example, will always be listening, and they must do so in order to receive any commands the user may make.

The future smart speaker market will likely be a protracted battle

In the movie "Untouchable Her", there is a virtual AI assistant named "Samantha". She has no specific image and can only communicate with the male protagonist through her voice, accompanied by a humorous "Samantha" , The male protagonist gradually got out of the haze of life and found hope again. In the end, the two became lovers only by voice communication, which made the audience envious.
