- Modify the speakers into computer speakers?
- 1. Modify the speakers into computer speakers? If you change the speaker of a car speaker to a computer, you need to add an amplifier. You can buy a ready-made amplifier board online. Of course, if it is just a speaker, it is best to make a speaker. A single speaker can sound, but the effect is not good without a box. You can choose a single-power digital power amplifier for the power board. It is highly efficient and produces little heat, so you don’t need a large heat sink. Take a look at the impedance of the speaker. The power amplifier board must match the impedance of the speaker. The power of 10W+10W is enough for home use. If you want to make a box, you can find the speaker drawings online according to the size of the speaker, and just use density board to make it. 2.

- Is it good to install a virtual machine on an Apple computer?
- 1. Is it good to install a virtual machine on an Apple computer? First of all, I can only say that your friend from the computer company is not a real Apple fan, but only loves Apple for the Apple brand. Of course, if you want to say that you really need a Windows system, outsiders have nothing to say. Apple has nothing to say about the compatibility of developed programs, and it is not an exaggeration to say that they are works of art. Moreover, because the MAC system prevents Windows viruses from running, it is more protective for accounts and completed works, so there are many program developers and other Designers prefer it. But unfortunately, for ordinary users, it is really not very convenient to operate. Back to the topic of virtual machines, the virtual machine itself is just a program. When you turn it off when not in use, it will not occupy resources. When you turn it on, it will definitely occupy Apple resources. There is nothing you can do about it.
