Q:Does the loudspeaker drive?
I remember in the 90's super king of a version of the speaker to solve some of the sound card speakers to see the disc silent.

Right click on the toolbar to customize the notice, the speaker icon is set to activities are not active show,
Q:What is the working principle of the loudspeaker?
2. Such speakers can be excellent performance, in the middle band can get a uniform frequency response.
Q:How the speaker converts the electrical signal into an acoustic signal
This magnetic field interacts with the magnetic field of the permanent magnet and drives the coil to vibrate. The cone connected to the coil is also vibrating, and the sound is emitted.
Q:Mobile phone speakers have noise, how to do it?
3, the speaker hole foreign body block or enter the dust impurities, it is recommended to customer service center to deal with;
Q:Speaker woofer what Q value is good
When the Q value is too high, the speaker is in an underdamped state, and the low frequency is excessively strengthened. The larger the Q value, the steeper the peak.So we say that the quality factor of the speaker that can not be too high can not be too low, usually take 0.2 ~ 0.5 is appropriate.
Q:How do speakers be classified?
Sorted by diaphragm: cone speakers, dome-shaped speakers, belt speakers, flat-panel drive speakers.
Q:Loudspeaker headset or headset has been unplugged how to do?
Normal (no exclamation point), this situation is also divided into two kinds: one is your sound card driver is not correct, the device can not run properly, the second is your sound card program version is too low, can not work, use Lu master upgrade driver
Q:How does the computer's speakers install?
2. If there is no drive disk, download a "drive life" or "driver wizard", it will automatically help you find the sound card driver, and then follow the prompts on the installation.

But the loudspeakers generally have their own speakers.
