Description

The double Magnet speaker of symmetrical expression
Technical field
This utility model relates to speaker, particularly to the double Magnet speaker of a kind of symmetrical expression.
Background technology
Speaker is a kind of conventional electro-acoustic transducer device converting electrical energy into acoustic energy, plays in sound reproduction place system Of paramount importance effect.Modal coil-moving speaker passes through electromagnetic induction principle, and by coil, the signal of telecommunication is converted into band Dynamic cone or the power of diaphragm vibration, compression promotes air around to produce resonance and send sound.
Speaker is mainly made up of vibrational system, magnetic circuit system, and wherein vibrational system includes that vibrating diaphragm, voice coil loudspeaker voice coil and centering are propped up Sheet, magnetic circuit system includes Magnet, washer and T ferrum.When the voice coil loudspeaker voice coil being in magnetic field has tone currents to flow through, can be by a friendship Become motive force and produce alternate motion, thus drive vibrating diaphragm shake, and then promotion air and sounding repeatedly.As being responsible for speaker Magnetic circuit provides the Magnet in magnetic field to be largely fixed the efficiency of speaker, the method traditional in order to improve the efficiency of speaker It is the size increasing Magnet, or after T ferrum, is further added by a secondary Magnet.First method is high along with single Magnet The increase of the increase magnetic field intensity of degree gradually weakens until being not changed in, and depends merely on increase magnet height inefficient.The second side Method is due to the positional distance voice coil loudspeaker voice coil same inefficiency farther out of secondary Magnet.
Utility model content
The purpose of this utility model is to provide the double Magnet speaker of symmetrical expression, at least can solve the problem that one of the problems referred to above.
For achieving the above object, according to an aspect of the present utility model, it is provided that the double Magnet speaker of a kind of symmetrical expression, Be mounted on frame including magnetic circuit system, vibrational system and frame, magnetic circuit system and vibrational system, magnetic circuit system include T ferrum with And all it being sheathed on upper Magnet, washer and the lower magnet of T ferrum, washer is between upper Magnet and lower magnet.Thus, upper and lower magnetic catch Washer, it is possible to be effectively improved the efficiency of speaker so that speaker acoustic efficiency is high.
In some embodiments, upper Magnet and lower magnet is in the same size.So that the magnetic field formed has preferably Symmetry.
In some embodiments, the opposite polarity of one end that upper Magnet is mutually close with lower magnet.Thus be formed The magnetic loop of effect.
In some embodiments, vibrational system includes semicircle rubber edge, vibrating diaphragm, bullet ripple and the sound being connected with vibrating diaphragm Circle, the outer rim of semicircle rubber edge is connected with frame, and the semicircle inner edge of rubber edge is connected with the outer rim of vibrating diaphragm, plays the outer rim of ripple Being connected with the inwall of frame, the inner edge playing ripple is connected with voice coil loudspeaker voice coil, and voice coil loudspeaker voice coil is sheathed on T ferrum.Thus, semicircle rubber edge and bullet ripple are altogether With the suspension constituting speaker, it is ensured that the vibration of voice coil loudspeaker voice coil maintains certain limit, it is to avoid voice coil loudspeaker voice coil is jumped out magnetic gap and caused The biggest distortion.
In some embodiments, the magnetic gap for accommodating voice coil loudspeaker voice coil, the position of voice coil loudspeaker voice coil and China it are provided with between T ferrum and washer Take charge of corresponding.Thus, voice coil loudspeaker voice coil is corresponding with the center of washer vertical direction thickness so that the magnetic force that voice coil loudspeaker voice coil produces is the most right Claim, be also beneficial to reduce the harmonic distortion that voice coil loudspeaker voice coil produces.
In some embodiments, vibrational system also includes dust cap, and dust cap is located at the middle position of vibrating diaphragm.Thus, Dust cap is used for preventing dust from falling in magnetic gap causes speaker to produce abnormal sound, and dust cap also radiates the work of a part of sound With, the sound of speaker can be changed as required with difform dust cap.
The beneficial effects of the utility model are: the double Magnet speaker of symmetrical expression uses upper and lower Magnet clamping washer, it is possible to have Effect improves the efficiency of speaker so that speaker acoustic efficiency is high;Upper lower magnet is in the same size and magnetic is reversed so that shape The magnetic field become has preferable symmetry and forms effective magnetic loop.
Accompanying drawing explanation
Fig. 1 is the structural representation of the double Magnet speaker of symmetrical expression of this utility model one embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Fig. 1 show schematically show the double Magnet speaker of the symmetrical expression according to a kind of embodiment of the present utility model.
As it is shown in figure 1, the double Magnet speaker of this symmetrical expression, including magnetic circuit system 1, vibrational system 2 and frame 3, magnetic circuit system System 1 and vibrational system 2 are mounted on frame 3.
Magnetic circuit system 1 includes T ferrum 11 and is all sheathed on the upper Magnet 12 of T ferrum 11, washer 13 and lower magnet 14, washer 13 Between upper Magnet 12 and lower magnet 14.Upper Magnet 12, washer 13 and lower magnet 14 are ring-type.Upper Magnet 12 and lower magnet 14 in the same size.During installation, the opposite polarity of one end that upper Magnet 12 is mutually close with both lower magnets 14.Upper Magnet 12 and under The magnetic field that Magnet 14 is formed has preferable symmetry and forms effective magnetic loop.
Vibrational system 2 includes semicircle rubber edge 21, vibrating diaphragm 22, plays ripple 23 and the voice coil loudspeaker voice coil 24 being connected with vibrating diaphragm 22.Semicircle The cross section of shape rubber edge 21 is semicircle.Semicircle rubber edge 21, vibrating diaphragm 22, bullet ripple 23 and voice coil loudspeaker voice coil 24 are loop configuration. The outer rim of semicircle rubber edge 21 is bonding with the upper end-face edge of frame 3, the inner edge of semicircle rubber edge 21 and the outer rim of vibrating diaphragm 22 Bonding.The outer rim playing ripple 23 is bonding with the inwall of frame 3, and the inner edge playing ripple 23 is connected with voice coil loudspeaker voice coil 24, and voice coil loudspeaker voice coil 24 is sheathed on T ferrum 11 Outward.Frame 3 is irony frame, and the bottom of frame 3 is connected with upper Magnet 12.Semicircle rubber edge 21 and bullet ripple 23 collectively constitute The suspension of speaker, it is ensured that the vibration of voice coil loudspeaker voice coil 24 maintains certain limit, it is to avoid voice coil loudspeaker voice coil 24 is jumped out magnetic gap and caused the biggest Distortion.
Being provided with the magnetic gap for accommodating voice coil loudspeaker voice coil 24 between T ferrum 11 and washer 13, the position of voice coil loudspeaker voice coil 24 is relative with washer 13 Should.Voice coil loudspeaker voice coil 24 is corresponding with the center of washer 13 vertical direction thickness so that the magnetic force that voice coil loudspeaker voice coil 24 produces is symmetrical above and below, also Advantageously reduce the harmonic distortion that voice coil loudspeaker voice coil 24 produces.
Vibrational system 2 also includes that dust cap 25, dust cap 25 are located at the middle position of vibrating diaphragm 22.Dust cap 25 is used for preventing Dust is fallen into and is caused speaker to produce abnormal sound in magnetic gap, and dust cap 25 also radiates the effect of a part of sound, can be according to need The sound of speaker is changed with difform dust cap 25.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, On the premise of creating design without departing from this utility model, it is also possible to making some deformation and improvement, these broadly fall into this practicality Novel protection domain.
