Abstract
A receiver without tuning paper consists of a magnetic cover, a magnetic steel, a pole chip, a voice coil, a diaphragm and a front cover; wherein, the outer opening of the discharging hole on the magnetic cover has no tuning paper, thereby eliminating the influence of the tuning paper to the quality. Moreover, the sticking place of the diaphragm is a right angle, without step, and also the radius of the folding sphere top of the diaphragm is considered to be increased. The utility model has comparatively perfect quality consistence and improves the producing efficiency at the same time.
Description
The utility model belongs to loud speaker in International Classification of Patents; Microphone; Gramophone adapter or other sound---pickoff group (HO4R) does not particularly have the receiver of adjustable sound paper.
Public moving coil receiver is made up of magnetic cover, protecgulum, magnet steel, pole piece sheet, voice coil loudspeaker voice coil and vibrating diaphragm.Because the influence of technical merit and numerous factors causes homogeneity of product relatively poor.In order to reach the performance index requirement, product has been sticked on adjustable sound paper on release aperture, by only on this paper, scrapes stripping perforation etc. in the test, makes it frequency response curve up to specification.Therefore, production efficiency is lower, and is subjected to factor affecting such as weather between product, and performance difference is bigger.
The purpose of this utility model provides a kind of receiver.Its acoustical behavior consistency is better, not influenced by weather etc. and produces difference, is no adjustable sound paper receiver.
For achieving the above object, except guaranteeing the precision of parts process and assemble, improve outside the consistency (all can reach by state-of-the art), main consideration reduces the error approach.It is as follows to disclose new technical scheme:
No adjustable sound paper receiver comprises magnetic cover, magnet steel, pole piece sheet, voice coil loudspeaker voice coil, vibrating diaphragm and protecgulum at least, it is characterized in that the collar extension of release aperture does not have adjustable sound paper.
Magnetic cover on the bonding plane of vibrating diaphragm and the inner peripheral surface of magnetic cover be the right angle, do not have step.
The sample of making according to such scheme owing to remove step, has reduced error, and after particularly removing adjustable sound paper this being subjected to the bigger measure of climatic effect, the difference that reaches the frequency response requirement between product has clear improvement.Improved the manufacturing work efficiency simultaneously.
Fig. 1 is a cutaway view of the present utility model; Fig. 2 is the vertical view of Fig. 1.
Find out that from figure no adjustable sound paper receiver is made up of magnetic cover 2, magnet steel 3, pole piece sheet 4, voice coil loudspeaker voice coil 1, vibrating diaphragm 8 and protecgulum 6.Be shaped on louver 7 on the protecgulum 6, magnetic cover 2 is shaped on release aperture 5 (sound regulating hole) and is connected with lug plate 9.Therefore said release aperture 5 collar extensions do not have adjustable sound paper, have eliminated the performance index that adjustable sound paper brings by climatic effect and have changed.Make magnetic cover 2 intersecting for the right angle simultaneously, do not have step with the bonding plane of vibrating diaphragm 8 and the inner peripheral surface of magnetic cover 2.In addition, vibrating diaphragm 8 ring ball top radiuses increase, and to reducing error certain positive role are arranged also.
Claims (2)
1, a kind of no adjustable sound paper receiver comprises magnetic cover [2], magnet steel [3], pole piece sheet [4], voice coil loudspeaker voice coil [1], vibrating diaphragm [8] and protecgulum [6] at least, and it is characterized in that does not have adjustable sound paper on the collar extension of release aperture [5].
2, no adjustable sound paper receiver as claimed in claim 1, it is characterized in that magnetic cover [2] and the inner peripheral surface of the splicing face of vibrating diaphragm [8] and magnetic cover [2] be the right angle, do not have step.
