Abstract
The utility model relates to a loudspeaker diaphragm, whose interior forms a plurality of fine air bubbles. The diaphragm of the utility model has low self natural frequency, high damping coefficient, low distortion, good acoustic quality, high diaphragm intensity, durableness and difficult breakage.
Description
Technical field
The utility model relates to the parts of a kind of seehears such as audio amplifier or loud speaker, the loud-speaker vibrating diaphragm in particularly a kind of audio amplifier or the loud speaker.
Background technology
For audio amplifier in the seehears or loud speaker, it is exactly its reproducibility that people propose the most basic requirement, just the performance of high-fidelity.Vibrating diaphragm as audio amplifier or loud speaker main sounding component, its quality is the key of decision audio amplifier pronunciation quality, the most direct influence pronunciation of the damping coefficient of vibrating diaphragm quality if mix underdamping, has situation out of control, occurs the losses of unnecessary harmonic shock and message.
Chinese patent 98229270.8 discloses a kind of high damping diaphragm of loudspeaker, " it is characterized in that being densely covered with on the matrix of conventional loudspeaker diaphragm materials of through hole in the formula of being dispersed in, fills out the flexible acoustic damping material of intrinsic gentle matter in said this through hole." but its intensity of vibrating diaphragm of this filling formula structure is difficult to guarantee breakage easily.
In summary, the vibrating diaphragm of described prior art on reality is used, obviously exists inconvenience and defective, so be necessary to be improved.
Summary of the invention
The purpose of this utility model provides a kind of damping coefficient height and the high audio amplifier vibrating diaphragm of intensity.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of loud-speaker vibrating diaphragm, the inside of described vibrating diaphragm form the thin bubble of a plurality of silk flosses.
Described loud-speaker vibrating diaphragm, wherein, described vibrating diaphragm penetrates and foaming by plastic cement.
Owing to adopt above-mentioned structure, self natural frequency height of vibrating diaphragm of the present utility model, the damping coefficient height, distortion is low, and tonequality is good; And, vibrating diaphragm intensity height, durable and cracky not.
Description of drawings
Fig. 1 is the stereogram of a kind of execution mode of loud-speaker vibrating diaphragm described in the utility model;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the A portion section enlarged diagram of Fig. 2.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
As shown in Figure 1, a kind of audio amplifier vibrating diaphragm 1, whole one-tenth funnel type certainly, as required, also can make other shape.
Shown in Fig. 2 to 3, vibrating diaphragm 1 forms the film that there is the thin bubble 2 of many silk flosses its inside by shot foamed moulding.Self natural frequency of vibrating diaphragm is low, the damping coefficient height, and distortion is low, and tonequality is good; And, vibrating diaphragm intensity height, durable and cracky not.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the present utility model all be included in the invention.
Claims (2)
1, a kind of loud-speaker vibrating diaphragm is characterized in that: the inside of described vibrating diaphragm forms the thin bubble of a plurality of silk flosses.
2, loud-speaker vibrating diaphragm according to claim 1 is characterized in that described vibrating diaphragm penetrates and foaming by plastic cement.
