Description
Technical field
The present invention relates to loudspeaker processing technique field, specifically a kind of speaker frame multistation processing unit (plant).
Background technique
Loudspeaker is made of electromagnet, coil, Loudspeaker diaphragm.Power frequency is converted into sound by loudspeaker.Physics
Principle, when electric current is by coil generating electromagnetic field, the direction in magnetic field is right-hand rule.It is assumed that loudspeaker plays C tune, frequency
For 256Hz, i.e., vibration 256 times per second, loudspeaker exports the alternating current of 256Hz, and 256 primary current per second changes, and issues C frequency modulation
Rate.When electric coil vibrates together with loudspeaker film, the air vibration of surrounding is pushed, thus loudspeaker generates sound.
The frequency for the sound wave that human ear can be heard is generally between 20 hertz to 20000 hertz, so general loudspeaker
It will be program setting within this range.Working principle and above-mentioned identical.The conversion process of energy is to be converted to magnetic by electric energy
Can, then mechanical energy is converted to by magnetic energy, then be converted to sound from mechanical energy.
Loudspeaker is a kind of energy transducer for electric signal being changed into acoustical signal, the shadow of the performance superiority and inferiority of loudspeaker to sound quality
Sound is very big.Loudspeaker is a most weak device in stereo set, and for acoustics, it is one most heavy again
The component wanted.Loudspeaker it is many kinds of, and price differs greatly.Audio electric energy is made by electromagnetism, piezoelectricity or electrostatic effect
Its cone or diaphragm vibration simultaneously generate resonance (sympathetic response) with the air of surrounding and make a sound.
Cone formula loudspeaker is also known as coil-moving speaker.
It is consisted of three parts: 1. vibrational system, including taper cone, voice coil and centring disk etc.；2. magnetic circuit system, packet
Include adopted magnet, magnetic conductive board and field stem etc. forever；3. auxiliary system, including frame, terminal plate, flanging and dustproof cover etc..When being in
When voice coil in magnetic field has tone currents to pass through, just generate with tone currents changing magnetic field, this magnetic field and permanent magnet
Magnetic field interacts, and vibrates voice coil axially, since loadspeaker structure is simple, bass is plentiful, sound quality is soft, frequency band
Width, but efficiency is lower.
Our most common electrodynamic type taper cone loudspeakers.I.e. we are usual to speak cone to dynamic cone speaker in the past
Loudspeaker is used although many high molecular material vibrating diaphragms, metal vibration diaphragm still based on cone, occurs simultaneously in vibrating diaphragm in 2014
Cone loudspeaker address is just worthy of the name.Taper cone loudspeaker is substantially by magnetic loop system (permanent magnet, stem, magnetic conduction
Plate), the three parts such as vibrational system (cone, voice coil) and support auxiliary system (centring disk, frame, pad side) constitute.
1. voice coil: voice coil is the driving unit of taper cone loudspeaker, it is to be wound on paper two layers with very thin copper conductor point
Guan Shang is generally wound with tens circles, also known as coil, and the magnetic for being placed in magnetic conductive core column and magnetic conductive board composition is doubted in gap.Voice coil and cone
It is fixed together, after acoustic current-meter signal is passed through voice coil, voice coil vibrations drive cone to vibrate.
2. cone: material used in the conical diaphragm of taper cone loudspeaker there are many kinds of class, generally have natural fiber and
Staple fibre two major classes.Natural fiber then uses artificial silk, nylon, glass frequently with cotton, timber, wool, spun silk etc., staple fibre
Glass fiber etc..Since cone is the acoustic radiating device of loudspeaker, the sound reproduction of loudspeaker decide to a large extent
Can, thus no matter any cone, it is desirable that should light rigidity again it is good, cannot be deformed because of environment temperature, humidity variation due to.
3. ring: ring is risen simultaneously to guarantee that cone is arranged along axial movement, the limit lateral movement of loudspeaker
To the effect for stopping cone front and back sky to dare circulation.The material of ring also utilizes plastics, natural rubber in addition to the material of common cone
Deng by being hot bonding on cone.
4. centring disk: centring disk is used to support the binding site of voice coil and cone, guarantees it vertically without skew.It is fixed
There are many concentric loops for heart branch on piece, are freely moved up and down voice coil in magnetic gap without moving laterally, guarantee voice coil not
It collides with magnetic conductive board.Dust cover on centring disk is that external dust etc. falls magnetic gap in order to prevent, avoids dust and voice coil
Friction, and loudspeaker is made to generate abnormal sound.
Wherein frame is carrier and the support of vibrational system and magnetic circuit system as the skeleton of loudspeaker, in the prior art
Frame mostly uses the mode of metal plate punching press to be processed, and the processing of speaker frame specifically includes blanking, stretches, rushes center
Hole rushes the processes such as waist hole, completes to need to change the mold or replace press machine after the processing of a process to carry out the processing of subsequent processing,
Efficiency is lower.
