Abstract
The utility model discloses a magnetic high sound pressure level loudspeaker, which comprises concentrating flux plates, a permanent magnet, a speech coil, a magnetic field stem, a loudspeaker basin stand, a vibrating diaphragm and a dust cover; a vibrating cone-shaped basin is fixed on the loudspeaker basin stand around the speech coil, is made of PET material, and has the thickness of 0.1mm; and the resistance of the speech coil is 21-27 ohm. The utility model has the characteristics of long continuous operating time, small basin diameter and low cost; and moreover, the sound pressure level can reach 107 plus or minus 3dB (A).
Description
Technical field
The utility model belongs to the loudspeaker techniques field, especially relates to a kind of magnetic-type high sound pressure level loud speaker.
Background technology
Loud speaker is the vitals of sound-reducing, and it can reproduce sound and buzzer reduction true to nature.In any sound system, final tonequality depends on loud speaker.Loud speaker is parts of sound system, with electronic signal and be translated into the real sound that the mankind can hear, if what sound system connected is the loud speaker of lower tone, even on state-of-the-art memory device, encode, play with top tape drive and amplifier, good so again recording and buzz sound it also being bad, sound pressure level also greatly less than, present common Φ 57 loud speaker sound pressure levels can only reach 90 ± 3dB (A), exceed this parameter as sound pressure level, its life-span can have a greatly reduced quality, and as too high, ventional loudspeakers can be burnt in a few minutes.
Summary of the invention
The purpose of this utility model is to improve the deficiency of prior art and provides a kind of sound pressure level can reach the magnetic-type high sound pressure level loud speaker that 107 ± 3dB (A), stream time are long, the basin footpath is little, cost is low.
The purpose of this utility model is to realize like this, a kind of magnetic-type high sound pressure level loud speaker, be between two magnetic conductive boards, to be fixed with permanent magnet, the center of permanent magnet is equipped with magnetic field stem stem and voice coil loudspeaker voice coil, and vibrating diaphragm covers voice coil loudspeaker voice coil, and speaker frame is fixedlyed connected with inboard magnetic conductive board, be characterized in being provided with the vibration taper basin that is fixed on the speaker frame around voice coil loudspeaker voice coil, vibration taper basin is the PET material, and thickness is 0.1 millimeter, and dust cap is installed in vibration taper basin center.
In order further to realize the purpose of this utility model, the resistance that can be described voice coil loudspeaker voice coil is 21-27 Ω.
Compared with the prior art the utility model has following distinguishing feature and good effect: vibration taper basin material of the present utility model changes the PET material that thickness is 0.1mm into, the voice coil loudspeaker voice coil resistance is between 21-27 ohm, voice coil loudspeaker voice coil cooperates perfect with vibration taper basin, after cooperating like this, sound pressure level can reach 107 ± 3dB (A), and can continuous operation not damage in 10 hours, this parameter had only in the past with big basin footpath loud speaker and could realize, present little basin footpath loud speaker has promptly reached this parameter, both provided cost savings like this, make product seem small and exquisite, good looking appearance again.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Embodiment, a kind of magnetic-type high sound pressure level loud speaker, with reference to Fig. 1, be to be fixed with permanent magnet 21 of two magnetic conductive board, the center of permanent magnet 2 is equipped with magnetic field stem stem 4 and voice coil loudspeaker voice coil 3, vibrating diaphragm 6 covers voice coil loudspeaker voice coil 3, speaker frame 5 is fixedlyed connected with inboard magnetic conductive board 1, be provided with the vibration taper basin 8 that is fixed on the speaker frame 5 around voice coil loudspeaker voice coil 3, vibration taper basin 8 is the PET material, and thickness is 0.1 millimeter, dust cap 7 is installed in vibration taper basin 8 centers, the resistance of voice coil loudspeaker voice coil 3 is 21-27 Ω, and the resistance of present embodiment voice coil loudspeaker voice coil 3 is 24 Ω, and this constitutes a kind of structure of the present utility model.
