What is the difference between a sound card and a microphone?

A sound card and a microphone are two different things entirely, the difference:

1. Sound card is also called audio card.

It is the most basic component of the computer multi-first system, and it is the realization of sound wave digital signals.

A type of hardware that converts to each other. The basic function of the sound card is to convert the original sound signal from the microphone, tape, and CD, and output it to earphones, speakers, amplifiers, tape recorders and other sound devices, or to send out the sound of synthesized instruments through the ** device digital interface (MIDI);

2. Microphone, also known as microphone, microphone. A microphone is an energy conversion device that converts sound signals into electrical signals. There are dynamic microphones, condenser microphones, electret and the recently emerging silicon microphone.

In addition, there are liquid microphones and laser microphones. Most microphones are electret condenser microphones that work by utilizing a polymeric material diaphragm with permanent charge isolation.

The microphone picks up the sound into the device, and the sound card converts the sound into a digital signal, saves it, and then converts it into an analog signal to output it. Missing one of the two, it doesn't sound good.

The sound card and the microphone are two different things. The sound card, also known as the audio card, is the most basic component of the computer system. It is a kind of hardware that realizes the conversion of sound waves and digital signals to and from each other.

A microphone, also known as a microphone, is an energy conversion device that converts a sound signal into an electrical signal.

A sound card is a group of chips in a computer that processes audio, and a microphone is a device that converts sound vibration into electrical signals.

Speaker and Microphone Differences:

The microphone is an energy conversion device that converts the sound signal into an electrical signal, that is, it is used to collect the sound of your speech, and the speaker is a transducer device that converts the electrical signal into an acoustic signal, which converts the electrical signal generated by the other party's speech into a Hongxun voice. To put it simply, the function of the microphone is to collect sound, and the function of the speaker is to **sound.

The speaker is made of an electromagnet.

The coil and the horn diaphragm are composed of the speaker converting the current frequency into sound. The final performance of a speaker is determined by the human ear's hearing, so this result may vary from person to person.

The mobile phone also has a speaker and a microphone (microphone), for example, the iphone11 mobile phone, the iphone11 has two speakers, one is located on the right side of the bottom of the mobile phone, and the other speaker is located at the top of the mobile phone screen.

Before the iPhone phone removed the headphone jack, the phone was a single speaker, located on the bottom right of the phone, and the bottom left was the radio microphone, and the stereo speaker was used for the first time on the iPhone 7 phone.

The dual-microphone noise reduction technology of the mobile phone refers to the "technical processing" in which the external noise is eliminated through technical processing, that is, there are two built-in microphones, one is stable and maintains a clear call, and the other microphone physically actively cancels the noise.

If you need to chat normally, you have to use a microphone, otherwise you can only listen and can't speak.

If it's those innovative sound cards, and you're going to talk, talk, sing, you need a microphone and headphones. Unless you're only going to listen to a song, don't sing, or talk, and you don't need a microphone.

The differences between a silent card and a sound card, i.e., an integrated sound card and an independent sound card, are as follows:

1. The functions are different.

The integrated sound card is mainly focused on ordinary voice chat and recording such as recording and playback. In addition to the normal sound function, the independent sound card also has special effects recording and other functions, and supports professional recording operations.

2. The sound effect is different.

Although the integrated sound card has some built-in sound effects such as valleys, auditoriums, etc., these sound effects can only be heard by the user himself, and these sound effects cannot be heard in the recording and chat rooms. The discrete sound card also contains a number of sound effects, which can be synchronized with the output, so that recordings can be recorded and heard in chat rooms.

3. Audio processing efficiency.

The stand-alone sound card is slightly higher than the integrated sound card in terms of analog-to-digital conversion and analysis, and its output speed is also higher than that of the integrated sound card.

There is a sound card and there is sound, and there is no sound card without a sound card.

The integrated sound card focuses primarily on playback, audio, and normal voice chat and recording. The independent sound card provides more functions such as input and output and chip support for special effects, and the professional sound card supports ASIO for professional recording.

Some integrated sound cards also have some built-in sound effects, such as auditoriums, valleys, football fields, sewers, etc., but those sound effects are only output on the monitor, and cannot be stored in the network chat room and system recording channel. Therefore, this effect can only be heard by yourself. The recording and the other party in the web chat room will not hear any effect.

Independent sound card, you can achieve effect synchronization, the effect of your own hearing, the recording can be recorded, and the other party in the chat room can also hear the sound effect synchronously. This difference is mainly in online karaoke entertainment and personal recordings.

Some independent sound cards have improved the processing of audio by a higher level,Both in analog-to-digital conversion and analysis are convenient,It is slightly higher than that of integrated sound cards,Of course,Now some integrated sound cards are also very good。 This difference lies in the support for some ** devices, such as some sound cards support SPDIF input and output, LR input and output, etc.

Some sound cards are focused on gaming or professional work areas. The support for game special effects is richer and more comprehensive. Stand-alone sound cards for professional work provide more audio solutions.

According to your needs, choosing the right sound card is the most important thing.

Professional singing equipment is more than just sound cards and microphones. There are two types of professional singing equipment.

One is to record it yourself and do it yourself later.

Hair ** on. This kind of requires a professional recording condenser microphone + recording sound card + relatively balanced monitor headphones.

The other is to sing on online entertainment platforms.

This is to buy K singing voice card + sound is passable condenser microphone + monitor or ordinary headphones + sound card debugging.
