Description
Technical field
This utility model relates to a kind of Microspeaker, is specifically related to a kind of Microspeaker with double washer structure.
Background technology
Speaker is the energy transducer that a kind of the signal of telecommunication is changed into acoustical signal, the good and bad shadow to tonequality of the performance of speaker
Ring the biggest.Speaker is a device the weakest in stereo set, and for acoustics, it be again one the heaviest
The parts wanted.Speaker of a great variety, and price differs greatly, and can be divided into electrodynamic type (i.e. moving-coil by its transduction principle
Formula), electrostatic (i.e. condenser type), electromagnetic type (i.e. reed), piezoelectric type (i.e. crystal formula) etc. several, latter two is used for rural area
In cable radio network；Can be divided into woofer, mid frequency ludspeaker, tweeter by frequency range, these are often in audio amplifier
Use as combination loudspeaker.Audio frequency electric energy pass through electromagnetism, piezoelectricity or electrostatic effect so that it is cone or diaphragm vibration and with surrounding
Air produce resonance (sympathetic response) and send sound.
Conventional micro-speaker design only one of which washer, causes utilizing in Magnet performance the highest, and is easily caused micro-
The total harmonic distortion of type speaker is too high.Currently without a kind of double washer structure Microspeakers, assemble magnetic by the second washer
Can, improve Magnet performance utilization rate, reduce the total harmonic distortion on Microspeaker.
Utility model content
The technical problems to be solved in the utility model is: propose a kind of Magnet performance utilization rate height and total harmonic distortion is low
There is the Microspeaker of double washer structure.
This utility model is to solve the technical scheme that above-mentioned technical problem proposes to be: a kind of double washer structure is miniature raises one's voice
Device, including U ferrum cup, is placed on described U ferrum cup center magnetic column, diaphragm and is connected to the voice coil loudspeaker voice coil bottom described diaphragm, described
Being fitted with the first washer sheet on the top end face of magnetic column, on the inwall of described U ferrum cup, connection has concentric with described first washer sheet
The the second washer sheet arranged, is formed between inner side edge edge and the outer side edges edge of described first washer sheet of described second washer sheet and supplies
Described voice coil loudspeaker voice coil bottom sides is along the annular gap passed through.
Further, the middle part of described first washer sheet offers the first through hole, and described magnetic column is provided with along its axle center
The second through hole that line is arranged, offers third through-hole at the bottom centre of described U ferrum cup, described first through hole, the second through hole and
The diameter of third through-hole is identical and position is relative.
Further, the bottom of described U ferrum cup is pasted with the tuning screen cloth covered on described third through-hole.
Further, in described first washer sheet and described second washer sheet are generally aligned in the same plane.
The beneficial effects of the utility model are:
This utility model has the Microspeaker of double washer structure, assembles magnetic energy by the second washer sheet, improve magnetic
Ferrum property utilization rate, reduces the total harmonic distortion on Microspeaker.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings the Microspeaker with double washer structure of the present utility model is described further.
Fig. 1 is the structural representation of the Microspeaker in this utility model with double washer structure.
Detailed description of the invention
Embodiment
According to Fig. 1, the double washer structure Microspeakers in this utility model, including U ferrum cup 4, it is placed on U ferrum cup
4 center magnetic columns 7, diaphragm 1 and be connected to the voice coil loudspeaker voice coil 2 bottom diaphragm 1, be provided with circuit board 6 in the bottom of U ferrum cup 4.
Being fitted with the first washer sheet 5 on the top end face of magnetic column 7, the inwall of U ferrum cup 4 connects to be had and the first washer sheet
5 the second washer sheets 3 being arranged concentrically, are formed between inner side edge edge and the outer side edges edge of the first washer sheet 5 of the second washer sheet 3 and supply
Voice coil loudspeaker voice coil 2 bottom sides is along the annular gap passed through.
Can be as preferably: the middle part of the first washer sheet 5 offers the first through hole, magnetic column 7 is provided with along its axle
The second through hole that heart line is arranged, offers third through-hole at the bottom centre of U ferrum cup 4, the first through hole, the second through hole and threeway
The diameter in hole is identical and position is relative.
Can be as preferably: the bottom of U ferrum cup 4 is pasted with the tuning screen cloth 8 covered on third through-hole.
Can be as preferably: in the first washer sheet 5 and the second washer sheet 3 are generally aligned in the same plane.
In this utility model, assemble magnetic energy by the second washer sheet 3, improve Magnet performance utilization rate, thus reduce miniature
Total harmonic distortion on speaker.
The above-described embodiment that is not limited to of the present utility model, the technical scheme of each embodiment above-mentioned of the present utility model that
This can form new technical scheme with combined crosswise, and the technical scheme that the most all employing equivalents are formed all falls within this practicality
In the protection domain of novel requirement.
