Many kinds of situation can cause the sound box to have the noise, for instance the speaker is disturbed, the interface or the connection line contact is bad, the sound box itself quality is inferior and so on.
Generally speaking, the speaker is a lot of active speakers, its internal will certainly exist amplifier, so the noise is unavoidable, the source of noise from the source can be roughly divided into electromagnetic interference, mechanical noise and thermal noise.
Speaker problems lead
Netizen consults the author said: His computer speaker recently suddenly appeared the noise, is the current sound, does not open any music has, the volume is bigger, the murmur is also big, before has been good, suddenly has been so, is the speaker bad, why does the speaker have the current sound? What if the speaker has current sound?

The code above may be the subscribeOn(xxx).observeOn(xxx) same in many places, and if we intend to unify it in a certain place, we can write this:

But so each time we need to call the above method, roughly like the following, the outermost is a function, which is tantamount to breaking the link structure:

The process of creating a node may be a bit the same, but note that the text contained in the element (in the Dom, these text also represents a node, therefore, you must also create the corresponding node for them. You cannot directly set the content of the text using the setnodevalue () method of the element object. Instead, you must use the setnodevalue () of the created Text object () to add the created element and its text content to the DOM tree.
