Abstract

The utility model discloses a loudspeaker vibrating diaphragm. A metal thin diaphragm layer of lighter specific weight is plated on the surface of the vibrating diaphragm in a vacuum mode, which leads the damping of the vibrating diaphragm to be reduced. When the utility model vibrates, the conduction of sound waves is accelerated. A bass part can be naturally eliminated through the vibrating diaphragm, which leads a mediant part and a high pitch part to be clear and natural, and leads sound quality not to be distorted. The utility model avoids the mode that bass is forcibly eliminated in an auxiliary mode by a splitter in the past. In addition, the utility model can also be made into a vibrating diaphragm structure, wherein, both surfaces of which are respectively provided with a light metal layer, which can generate the efficiency of super high pitch.

Description

A kind of diaphragm of loudspeaker

The utility model relates to a kind of loud speaker, and is especially relevant with the diaphragm of loudspeaker.

General loud speaker drum paper is by stationery, plastics, synthetic resin, fiber, weave cotton cloth, materials such as metal are made, for building the demand of alt or bass, must be by the partial device auxiliary, in not wanting, high pitch or bass are forced to eliminate, and stationery, plastics, the fibrage class, base material vibrating diaphragms such as ceramic-like are when listening the heavy metal music, because of the rigidity deficiency, so tonequality is unclear, the vibrating diaphragm of aluminium titanium base material is when vibration, frequency is too high, glouglou in the time of can sending class such as Metal Cutting, too ear-piercing, tonequality is too firm, special sound effects such as only suitable heavy metal music, do not meet and in alt, show the distortionless sound of nature,, be a difficult problem of demanding urgently overcoming of the same trade in fact more than for using the disappearance that drum paper generally has at present always.

The purpose of this utility model is to provide a kind of diaphragm of loudspeaker, can make alt partly analyse nature more clearly, and tonequality is undistorted; Also can produce the effect of superelevation sound.

For reaching above-mentioned purpose, the utility model plates the lighter metal film layer of one deck proportion in the vacuum plating mode on the vibrating diaphragm surface.In addition, the utility model also can also plate one deck light metal thin layer on the vibrating diaphragm backside surface.

After adopting said structure, the utility model can make the vibrating diaphragm damping diminish because of the vibrating diaphragm surface is coated with than the light metal thin layer, and during vibration, the sound wave conduction is accelerated, and by vibrating diaphragm itself bass is partly eliminated naturally, makes alt partly analyse nature more clearly, and tonequality is undistorted; And the vibrating diaphragm backside surface also is coated with than the light metal thin layer, can make the vibrating diaphragm damping littler, and during vibration, the sound wave conduction is faster, thereby produces the effect of superelevation sound.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the utility model embodiment stereogram;

Fig. 2 is the utility model embodiment profile;

Fig. 3 is Fig. 2 A portion enlarged drawing;

Fig. 4 is another embodiment profile of the utility model;

Fig. 5 is Fig. 4 B portion enlarged drawing.

See also shown in Fig. 1-3, the utility model vibrating diaphragm 1 is in vibrating diaphragm 1 base material: plate the lighter metal film layer of one deck proportion 11 in the vacuum plating mode on as stationery, plastics, fibrage class, ceramic-like surface: as aluminium, titanium, owing to have one deck light metal thin layer 11 on vibrating diaphragm 1 substrate surface, vibrating diaphragm 1 damping is diminished, during vibration, the sound wave conduction is accelerated, can itself bass partly be eliminated naturally by vibrating diaphragm 1, make alt partly analyse nature more clearly, tonequality is undistorted, can save the mode that in the past needs by the auxiliary elimination bass of partial device.

Moreover, see also shown in Fig. 4,5, the utility model vibrating diaphragm 1 also can also plate the lighter metal film layer of one deck proportion 11 in the vacuum plating mode on vibrating diaphragm 1 substrate backside surface, all has one deck light metal thin layer 11 owing to vibrating diaphragm 1 base material is two-sided, make vibrating diaphragm 1 damping littler, during vibration, the sound wave conduction is faster, can produce the effect of superelevation sound.

Claims

1, a kind of diaphragm of loudspeaker is characterized in that: be coated with the lighter metal film layer of one deck proportion on the vibrating diaphragm substrate surface.

2, according to the described a kind of diaphragm of loudspeaker of claim 1, it is characterized in that: also be coated with the lighter metal film layer of one deck proportion on the vibrating diaphragm substrate backside surface.
