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
conditions allowed for the transformer to install shielding shield effect is very obvious, can be the greatest degree of leakage magnetic barrier, shielding cover can only be made of iron-type materials. We should try to choose the big brand, the materials used solid products, in addition, the use of external transformers is also a good solution.

The traditional way to define arrays is this:1 var moviesthatneedbetterwriters = new Array (2 ' Transformers ', ' Transformers2 ', ' Avatar ', ' Indianajones 4 ' 3);The abbreviated version is this:1 var moviesthatneedbette

Each language has its own special place, and for JavaScript, using VAR to declare variables of any type, the scripting language looks simple, but it takes a lot of experience to write elegant code. This article provides a list of seven details that JavaScript beginners should pay attention to, and share them with you.

(1) Simplify the codeJavaScript defines objects and arrays very simply, and we want to create an object that is generally written like this:
Copy Code code as follows:
var car = new Object ();
Car.colour = ' red ';
Car.wheels = 4;
Car.hubcaps = ' spinning ';
Car.age = 4;
The following writing can achieve the same effect:
Copy Code code as follows:
var car = {
Colour: ' Red ',
Wheels:4,
Hubcaps: ' Spinning ',
Age:4

Configuring Bulkloader.yaml Files
The Bulkloader.yaml file consists mainly of two parts, Python_preamble and Transformers.
Python_preamble:

In general, you don't have to change this part unless you want to use other modules or methods in the conversion format, for exampl
Each language has a special place. For JavaScript, using var can declare any type of variables. This script language looks very simple, however, to write elegant code, you need to constantly accumulate experience. This article lists seven details that JavaScript Beginners should pay attention. 1. Simplified code
It is very simple to define objects and arrays in JavaScript. We want to create an object, which is generally written as follows:
The Code is as follows:
Var car = new Object ();Car.
a full set of Apple devices, including iPhone, iPad, iMac, and iWatch, in combination with their own UI wallpapers, it looks very realistic. Like a device in reality, the screen also has a switching effect, but this is a timed switch and cannot be switched by sliding. If you are interested, you can implement it on your own.

subsequent statement is much shorter, and you do not need to repeat the object name.
In addition, there is a simple way to write arrays. In the past, we declared arrays as follows:
The Code is as follows:
Var moviesThatNeedBetterWriters = new Array ('Transformers ', 'transformers2', 'Avatar', 'Indiana Jones 4');
A more concise statement is as follows:
The Code is as follows:
Var moviesThatNeedBetterWriters = ['

that the column name is case sensitive When configuring the field. If you use an Oracle database, because Oracle uses an upper-case column name by default, you must write the column in upper-case. In some cases, our data contains clob fields and rich text fields. SOLR provides some transformers converters that can pre-process these fields before saving the index. For example, you can convert clob to string clobtransformer, and you can cut all HTML-ma
