How do microphones and speakers amplify sound?

It's because the speaker and the microphone have made a corresponding function to amplify the sound,First of all, the microphone and the speaker will be directly absorbed,After the sound is absorbed,And then through some internal devices to reconvert the output,And then amplify the sound,In fact, it is to amplify the sound signal。

When making microphones and speakers, you put a part inside that allows you to turn up the sound at will, and when the sound reaches the part, the volume is amplified.

Since a sound amplifier is installed in both the microphone and the speaker, the volume is amplified when the sound signal is transmitted to the sound amplifier.

A loudspeaker is installed inside the machine, which can make the sound of these two things louder and smaller according to the remote control.

When the volume has been turned up to the maximum, but the sound is still very quiet, it may be that the program has turned down the volume, so the system sound can not continue to be turned up:

2. Select [Hardware & Sound] in the control panel, if you don't find this option, you can select [Category] in the upper right corner.

3. In the Hardware and Sound window, select [Change System Sound] in the [Sound] selection on the right side.

4. Select [Recording] in the upper tab, select the default device for the microphone ("Default Device" will be displayed below), and right-click to select properties.

5. Select [Level] on the tab at the top of the "Microphone Array Properties" interface, and increase [Microphone Strengthening] to the maximum.

Microphone settings: small speaker in the lower right corner Right click Recording device: Set the existing microphone as the default device during recording.

Then double-click the microphone or dot properties in the level to adjust the volume of the microphone and the microphone enhancement (this is adjusted appropriately, turn up the amplification, some computers will have current sound), and select noise suppression and echo cancellation in the enhancement field.

Select Listen to this device in the listening, you can hear your own voice (this normal use is not selected, some computers will freeze or have noise).

6. After that, click Record, click Microphone, and click Properties.

7. Then click the level, then slide the slide button below the microphone to adjust the sound volume, and click OK. This adjusts the sound volume of the microphone.

1. Increase the output power of the power amplifier, so that the power amplifier can transmit a larger signal to the speaker.

2. Increase the sound efficiency of the speaker, so that the speaker can emit greater sound pressure under the same large signal, and the specific method must have professional knowledge, not a few words can be clear, only some direction references: 1. The power formula is: power = the square of the output voltage divided by the impedance of the speaker.

That is, the higher the output voltage, the lower the impedance of the horn, and the greater the output power. If you want the power amplifier output voltage to be high, you can increase the power supply voltage of the power amplifier, or thicken the speaker wire to reduce the loss. If you want to reduce the impedance of the horn, you can change the horn to a low-impedance horn, such as 8 ohms to 4 ohms.

2. To increase the sound efficiency of the speaker, it can be replaced with a high-sensitivity speaker, replaced with a high-efficiency cabinet, etc. The above is just a direction, and it must be done in a practical way, and the impact of any change on the rest of the world should be fully considered.

Computer speakers mainly refer to the speakers used around computers and other multi-** equipment, mainly suitable for iPod, MP4, mobile phones, PSP game consoles, computer products, etc. Depending on the interface, there are also differences in the devices that can be connected.

Next, let's take a look at how to turn up the computer sound.

1. The sound card driver may be incorrect, reinstall it.

2. The volume is muted, turn on the small speaker and remove the mute check.

3. Turn off all the volumes, turn on the small speakers and turn the volume up.

4. The audio output and audio input are confused, the output is green and the input is pink.

5. The front audio jumper is incorrect, and the chassis should be adjusted according to the motherboard manual.

6. If there is a hardware problem with the sound card, replace it.

7. Turn off the sound option, open the sound option in the control panel and open it 8. There is a problem with that song.

9. The public end of the audio cable connecting the computer to the audio is broken.

10. The plug or socket of the audio cable has rust or oxide, which causes the resistance to increase11. There is a problem with the front of your audio.

12. The volume control potentiometer is worn and replaced.

13. The feedback resistance of the power amplifier increases, resulting in a decrease in gain, and the sound will be smaller!

Turning up the volume of the speaker can be done in the following ways:

1.Increase the output power of the power amplifier, so that the power amplifier can transmit a larger signal to the speaker;

2.Increase the sound efficiency of the speaker, so that the speaker can emit greater sound pressure under the same large signal;

3.Increase the sound effect of the speaker, and replace the speaker with a high-sensitivity speaker;

4.Change the cabinet of the speaker and replace the cabinet of the speaker with a cabinet with amplification effect to increase the volume effect.

If you want to get more power output, then you need to increase the supply voltage, but blindly increasing the voltage will burn the components. It is necessary to understand the circuit composition, the maximum working voltage of all chips, and then make adjustments. There is no other way.

Ways to make the headphones' microphone louder:

1. In the lower right corner of the computer, find the logo of a small speaker, which is the button to adjust the sound.

2. Then move the mouse to the icon, right-click, and an option box will come out, with an option of "sound" on it, move the mouse over, and then left-click.

3. After clicking, a dialog box will appear, which has a "Record" option in it, click into it.

4. After clicking, you will see an option of "built-in microphone", and then move the mouse over it, and double-click to open it.

5. Next, click on the "Level" option in the red box.

6. You will see a slider that can adjust the size of the microphone, and you can adjust the size of the microphone according to your needs. Move the slider all the way to the right, and you'll be the loudest.

Here's how to make the headphones' microphones louder:

1. Take win7 system as an example, right-click the sound icon in the taskbar on the desktop, and select the "Recording Device" menu;

2. In the page of recording devices that opens, double-click the microphone device you are currently using.

3. In the special page of the microphone device property page, click the "Level" tab at the top of the page;

4. In the level setting page, drag the sound setting bar of the microphone device to the maximum;

5. Finally, click the "OK" button at the bottom of the page to save the settings.

Summary. To make your computer microphone louder, you can try the following:1

Increase microphone volume: In Windows system, right-click the volume icon on the taskbar, select "Recording Device", find the microphone you are using in the pop-up window, double-click to open its properties, switch to the "Level" tab, and adjust the "Microphone" volume to the maximum. 2.

Adjust Microphone Gain: Also in the Level tab of the microphone properties, you can also adjust the gain of the microphone to increase the sensitivity of the microphone and thus increase the volume of the microphone. 3.

Check the microphone connection: If the microphone connection is poor or damaged, it may cause the microphone to be not loud enough or noisy. Please check that the microphone is properly connected to the computer and that it is not damaged.

4.Choose the right microphone: If your computer's built-in microphone isn't of the same quality or doesn't meet your needs, consider purchasing an external microphone.

External microphones are generally of high quality and can be adjusted as needed to improve the clarity and volume of the sound. 5.Using audio software:

If you need to record high-quality audio, you can use professional audio software, such as Adobe Audition, Audacity, etc., through the processing and adjustment of the software, you can make the volume of the audio more balanced and clear. The above are some commonly used methods, I hope it can help you.
