Abstract
A treble frequency loudspeaker sound diaphragm is provided. Two filtering sound-absorbing layers are bonded on a sound diaphragm body and are made of a sound-absorbing sponge material. The sound diaphragm body comprises a ball top part arranged on a central position and a folding ring part mounted around the ball top part. The filtering sound-absorbing layers are disposed on the ball top part and the folding ring part of the sound diaphragm body. The beneficial effects of the sound diaphragm are that the sound diaphragm provided by the utility model can preferably control a loudspeaker frequency response curve of a high-frequency resonance peak to be relatively flat, control frequency to be relatively wide and provide the preferable timbre treble frequency loudspeaker for people. Panel design of the loudspeaker is not limited. Conventional thread-film treble panels can be widely used. Redundant information is absorbed by the filtering sound-absorbing layers, noises cannot appear when the sound diaphragm vibrates, so that timbre is preferable.
Description
Technical field
The utility model relates to a kind of sound film of loudspeaker, particularly a kind of high pitch loudspeaker sound film.
Background technology
We compare with external advanced person's technology country in the technology aspect the manufacturing high pitch loudspeaker and also have certain gap at present, so that some gaps of existence qualitatively of the high pitch loudspeaker of the high pitch loudspeaker of China's domestic production and more external famous brands, particularly more there is bigger gap in the tonequality aspect.
As everyone knows, the tonequality quality of high pitch loudspeaker depends primarily on the quality of sound membrane material, but because there is a certain distance in the technology of the technology of the sound membrane material that China makes and external advanced country, and in certain period, technically be difficult to surmount external advanced country technology, only seeking breakthrough on the sound membrane structure.
At present, the sound film mainly comprises voice coil loudspeaker voice coil, Metal Ball top and soft limit; Wherein, this voice coil loudspeaker voice coil is provided in a side of and is arranged on this soft limit, and this Metal Ball top is provided in a side of on this soft limit; It is corresponding with this voice coil loudspeaker voice coil, and this voice coil loudspeaker voice coil directly contacts with the Metal Ball top.That is to say how many sizes of this voice coil loudspeaker voice coil is set to than Metal Ball top undersized, this voice coil loudspeaker voice coil is directly contacted with the Metal Ball top, and this soft limit just is connected, and does not touch and directly be not connected with this voice coil loudspeaker voice coil with this Metal Ball top.Because this sound membrane structure, voice coil loudspeaker voice coil and Metal Ball top contact can produce high-frequency resonant, and the information that produces during the vibration of sound film is unnecessary, influences sense of hearing; And the method for present this defective of solution is mainly set up an eqalizing cricuit, because the sound film of this structure is after being provided with eqalizing cricuit, the redundant information of generation has obtained certain alleviation, and the tonequality that makes loud speaker is better than former; But, because after setting up eqalizing cricuit, the design of whole sound film can become and relatively bother, and after being provided with eqalizing cricuit, has also known the liter that prolongs of sound film high frequency, and the manufacturing cost height, be unfavorable for promoting.
Summary of the invention
At the technical deficiency of traditional sound film, the utility model provides a kind of sound film of New-type loudspeaker.
To achieve these goals, the measure taked of the utility model:
A kind of high pitch loudspeaker sound film be bonded with two circle filtering sound absorbing layers on the sound membrane body, and the filtering sound absorbing layer is made for the sound-absorbing sponge material;
Described sound membrane body is positioned at the ball top at center and around the ring portion at ball top;
Described filtering sound absorbing layer is positioned on the sound membrane body ball top;
Described filtering sound absorbing layer is positioned in the ring portion of sound membrane body.
The beneficial effects of the utility model: it is more flat that the utility model sound film can be controlled high-frequency resonant peak loudspeaker frequency response curve preferably, frequency is wideer, the high pitch loudspeaker of better tonequality is provided for people, and the panel designs of loud speaker is unrestricted, can be extensive use of common cortina high pitch panel, by filtering sound absorbing layer absorption redundant information, the noise that also can not produce during the vibration of sound film makes tonequality sound better.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
As shown in Figure 1: a kind of high pitch loudspeaker sound film, be bonded with two circle filtering sound absorbing layers 2 on the sound membrane body 1, and filtering sound absorbing layer 2 is made for the sound-absorbing sponge material; Described sound membrane body is positioned at the ball top at center and around the ring portion at ball top; Described filtering sound absorbing layer is positioned on the sound membrane body ball top; Described filtering sound absorbing layer is positioned in the ring portion of sound membrane body.
Claims (4)
1. a high pitch loudspeaker sound film comprises sound membrane body (1), it is characterized in that, be bonded with two circle filtering sound absorbing layers (2) on the sound membrane body (1), and filtering sound absorbing layer (2) is made for the sound-absorbing sponge material.
2. a kind of high pitch loudspeaker sound film according to claim 1 is characterized in that, described sound membrane body is positioned at the ball top at center and around the ring portion at ball top.
3. a kind of high pitch loudspeaker sound film according to claim 2 is characterized in that, the filtering sound absorbing layer is positioned on the sound membrane body ball top.
4. a kind of high pitch loudspeaker sound film according to claim 2 is characterized in that the filtering sound absorbing layer is positioned in the ring portion of sound membrane body.
