Abstract
The utility model belongs to the field of a vibrating diaphragm in an earphone horn and specifically provides a composite sound diaphragm. The composite sound diaphragm is characterized in that: the composite sound diaphragm mainly comprises a vibrating diaphragm body which is a polyurethane base material structure; and the vibrating diaphragm body is composed of a high-frequency vibration portion ball roof and a low-frequency vibration portion bending ring, wherein the bending ring is arranged around the ball roof; and the ball roof is composited with at least one layer of auxiliary membrane. The polyurethane is adopted as a base material in the composite sound diaphragm, so that the requirement for low frequency vibration of the low-frequency vibration portion bending ring is met; while as to the requirement for the large-strength ball roof of the high frequency, the ball roof is composited with one layer or a plurality of layers of materials, such as PET and the like, the traditional strength of which is relatively large and which is light, so that the low frequency and the high frequency are both taken into consideration, frequency band is further broadened, triple frequency is balanced, and tone quality is improved. The composite sound diaphragm is simple in structure and high in practicality.
Description
Technical field
The utility model belongs to the vibrating diaphragm field in earphone horn, specifically a kind of compound voice diaphragm.
Background technology
Earphone requires the requirements such as tonequality is good, tone color is pure, bass is plentiful and dive is dark, alt is bright to the sound of its loudspeaker.But cavity space is little after earphone, its loudspeaker can not be brought into play optimum performance, and low frequency part distortion is serious.Vibrating diaphragm in earphone horn is mainly used the materials such as PEI, PET, PAR, PPS at present, and they all can not meet tut requirement.In addition, at present traditional Loudspeaker diaphragm all only forms with a kind of thin-film material hot-pressing.This vibrating diaphragm is mainly by the ball top at center be located at the Periapical ring of ball and form.Ball top rigidity intensity is better, and the extension of corresponding high frequency is better, also broader; Ring compliance soften is higher, and corresponding low frequency dive is darker.Therefore, single thin film is difficult to take into account the sound requirement of low-and high-frequency.Generally, traditional method is generally to adopt thin and soft vibrating diaphragm to meet low frequency, thereby high frequency seems bright not very thin, and therefore earphone sound just show not good enough.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of compound voice diaphragm; It has solved the former of vibrating diaphragm traditional material and individual layer thereby has caused the problems such as sound performance is not good enough, frequency band is wide not.
In order to achieve the above object, a kind of compound voice diaphragm of the utility model, mainly comprises a vibrating diaphragm body, and described vibrating diaphragm body is polyurethane matrix structure; This vibrating diaphragm body consists of the ring of the ball top of high frequency vibrating portion and low frequency vibration portion, and described ring is arranged in ball top around; And, on ball top, be also compounded with at least auxiliary film of one deck.
Described polyurethane is commonly called as PU, and the material of auxiliary film can be used the larger and light materials of traditional strength ratio such as PEI, PET, PAR, PPS.This auxiliary film can be one deck, can be also two-layer or multilayer.
Preferably, described ring and ball push up the structure that is formed in one.
Preferably, the lower surface of described ring is dome shape structure.
Preferably, the lower surface on described ball top is dome shape structure.
Preferably, described auxiliary film is arranged on the lower surface on ball top.
With respect to traditional materials such as PET, PU is more soft, environmental protection, is made into the vibrating diaphragm body of same specification, and its high frequency is more very thin bright, and low frequency is plentiful.The utility model adopts polyurethanes (PU) as the main material of vibrating diaphragm body, and it can meet the requirement of its low-frequency vibration concerning the ring of low frequency vibration portion; And for high frequency to the large demand of ball top intensity, the utility model is at larger and light materials of traditional strength ratio such as compound one or more layers PET in ball top place, thereby takes into account high and low frequency, and then widened frequency band, three have frequently obtained balance, have improved tonequality.This is simple in structure, practical.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of traditional vibrating diaphragm body;
Fig. 2 is cross-sectional view of the present utility model.
Wherein, 11 is ball top, and 12 is ring, and 21 is ball top, and 22 is ring, and 23 is auxiliary film.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail, but not as to restriction of the present utility model.
Fig. 1 is the cross-sectional view of traditional vibrating diaphragm body, with reference to Fig. 1, traditional vibrating diaphragm body is mainly by the ball top 11 at center be located at ball top 11 ring 12 around and form, and this vibrating diaphragm body is mainly used the materials such as PEI, PET, PAR, PPS, and all only with a kind of thin-film material hot-pressing, forms.Ball pushes up that 11 rigidity intensity are better, and the extension of corresponding high frequency is better, also broader; Ring 12 compliance softens are higher, and corresponding low frequency dive is darker.Therefore, single thin film is difficult to take into account the sound requirement of low-and high-frequency.Generally, traditional method is generally to adopt thin and soft vibrating diaphragm to meet low frequency, thereby high frequency seems bright not very thin, and therefore earphone sound just show not good enough.
Fig. 2 is cross-sectional view of the present utility model, and with reference to Fig. 2, a kind of compound voice diaphragm of the utility model embodiment, mainly comprises a vibrating diaphragm body, and described vibrating diaphragm body is polyurethane matrix structure; This vibrating diaphragm body consists of the ring 22 of the ball top 21 of high frequency vibrating portion and low frequency vibration portion, and described ring 22 is arranged in ball top 21 around; And, on the lower surface on ball top 21, being also compounded with the auxiliary film 23 of one deck, this auxiliary film 23 is made by PET material.
Described polyurethane is commonly called as PU, and the material of auxiliary film 23 not only can be used PET, can also use the larger and light materials of traditional strength ratio such as PEI, PAR, PPS.Certainly, this auxiliary film 23 can be one deck, can be also two-layer or multilayer.
With reference to Fig. 2, described ring 22 and ball top 21 structure that is formed in one; And the lower surface on described ring 22 and ball top 21 is all dome shape structure.
Comparison diagram 1 and Fig. 2, with respect to traditional materials such as PET, PU is more soft, environmental protection, is made into the vibrating diaphragm body of same specification, and its high frequency is more very thin bright, and low frequency is plentiful.The utility model adopts polyurethanes (PU) as the main material of vibrating diaphragm body, and its ring 22 concerning low frequency vibration portion can meet the requirement of its low-frequency vibration; And for high frequency, ball is pushed up to the demand that 21 intensity are large, and the utility model pushes up the larger and light PET material of the 21 compound one deck strength ratio in place at ball, thereby takes into account high and low frequency, and then has widened frequency band, and three have frequently obtained balance, have improved tonequality.This is simple in structure, practical.
Below the utility model is described in detail, but apparent, those skilled in the art can carry out various changes and improvements, and does not deviate from the scope of the present utility model that appended claims limits.
