CN201408621Y - Inductor of frequency divider of sound box - Google Patents

Abstract

The utility model relates to an inductor of a frequency divider of a sound box, which consists of a core pipe and a winding, wherein the core pipe is a hollow iron pipe with a through hole, and the winding wound on the core pipe is a copper wire or an aluminum wire. The inductor has fine tone quality, clear high pitch, magnetic middle pitch, namely voice, quiet background music and wider diapasoncompared with other frequency dividers, and is simple in manufacturing and low in cost.

Description

The loudspeaker enclosure divider inductance

Technical field

The utility model relates to a kind of loudspeaker enclosure divider inductance.

Background technology

The inventor was engaged in the speaker production industry nearly 20 years, wherein was engaged in speaker production and maintenance work in 10 years in the public place of entertainment, during be subjected to a problem puzzlement: the inductance of frequency divider often burns in the audio amplifier.Have no way, the frequency divider that burns have to have been changed the high-power frequency divider of professional usefulness, burn phenomenon and take a turn for the better to some extent, but happen occasionally.Helplessly, in order to reduce expenses, have to own coiling, unintentionally find, replace original solid silicon steel disc or the coiling of magnetic core pipe with hollow iron pipe, not only tonequality has been got well many, the happy background of liaison is also quiet many, and range is also more open than other frequency divider simultaneously, but also has saved a very big spending, save about 1/3rd copper cash than general inductance, make simple and convenient simultaneously.Up to the present none example is burnt, and will drop to minimum because of the fire possibility that frequency divider in the audio amplifier causes.Because the copper cash price rises, and in order further to reduce cost, the inventor brings into use aluminum steel coiling experiment, found that high pitch more beautiful, middle pitch are that voice has magnetic, facts have proved, none example of user was dissatisfied afterwards.

Summary of the invention

The purpose of this utility model is: solid silicon steel disc or the magnetic core pipe that the hollow iron pipe of a kind of usefulness replaces original audio amplifier frequency division inductance is provided and replaces the new-type audio amplifier frequency division inductance of the coiling of the copper wire on the pipe in original audio amplifier frequency division inductance with aluminium wire.

It is achieved in that it by the core pipe with the coiling form.The structure of core pipe is the hollow iron pipe that is provided with a through hole, and the coiling of twining thereon is copper cash or aluminum steel, can quicken heat radiation like this, improves power.In addition, bass effect is good when using copper cash, and high pitch is effective when using aluminum steel, can select as required.

Advantage of the present utility model is: 1, tonequality is good, and high pitch is beautiful, and middle pitch is that voice has magnetic, the music background peace and quiet, and range is also more open than other frequency divider simultaneously; 2, make simply, reduce cost.
