Abstract
The utility model discloses a composite material tweeter, aiming to provide the composite material tweeter which has pure timbre and full bass, intermediate frequency and high frequency thereof are loud at the same time, and is used in a miniature loudspeaker or a receiver. The composite material tweeter upwardly comprises a bottom film which consists of a PAR thin film and a PU thin film and has a tweeter suspension ring, a dome on the bottom film uses honeycomb wood boards or honeycomb foam boards and aluminum foils, adhesives are used to bond the bottom film, the honeycomb wood boards or the honeycomb foam boards and the aluminum foils sequentially. The resonant frequency FO using the loudspeaker is only 450 Hz, the timbre is very perfect, the dome part uses a novel composite aluminum film technology, the rigidity of the dome part is ensured, meanwhile the aluminum foils has the characteristics of light quality and less sound wave adsorbed, therefore the intermediate frequency and high frequency can be continued effectively, so that the voice is loud, the distortion is less, and the requirement of high fidelity miniature loudspeaker is met.
Description
Technical field
The utility model relates to loud speaker, relates in particular to the composite material vibrating membrane of using on a kind of Microspeaker or the receiver.
Background technology
Electronics and communication product equipment such as employed mobile phone, PDA, notebook computer, digital camera, MP3, MP4 in the modern life require to the sound of loud speaker that tone color is pure, bass is plentiful, medium-high frequency also requires loud and clear simultaneously.But because the volume of electronic product is more and more littler, the space that the design of each body places for loud speaker or receiver is very limited, therefore the required also greatly reduction of back cavity volume space of loud speaker, cause loud speaker can not bring into play best efficiency, the low frequency part loss is serious, so invention ultralow frequency Microspeaker just becomes development today trend.And present PU material just can not satisfy above-mentioned requirements as vibrating membrane.
The utility model content
The purpose of this utility model provides a kind ofly makes that tone color is pure, bass is plentiful, medium-high frequency is simultaneously loud and clear, the composite material vibrating membrane of using on Microspeaker or the receiver.
In order to achieve the above object, the composite material vibrating membrane is achieved through the following technical solutions: it upwards includes the counterdie of PAR film and the compound composition band of PU film vibrating membrane ring successively, honeycomb wood based panel or honeycomb cystosepiment and aluminium foil are adopted in ball top on the counterdie, use adhesives successively between counterdie, honeycomb wood based panel or honeycomb cystosepiment and the aluminium foil.
According to the composite material vibrating membrane that such scheme is made, its advantage is:
1, tone color is very perfect, has only 450Hz with the resonance frequency FO of this product loud speaker.
2, the ball top portion adopts NEW TYPE OF COMPOSITE aluminium membrane technology, has guaranteed the rigidity of ball top portion, and aluminium foil has light weight simultaneously, the absorption sound wave is few, so medium-high frequency can access effective continuity, causes sound loud and clear.
3, distortion has reached the requirement of high-fidelity Microspeaker for a short time.
Description of drawings
Fig. 1 is the profile of composite material vibrating membrane.
Wherein: 1, PAR film; 2, PU film; 3, vibrating membrane ring; 4, counterdie; 5, ball top; 6, honeycomb wood based panel or honeycomb cystosepiment; 7, aluminium foil; 8, adhesive.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of composite material vibrating membrane.As seen from the figure, it upwards includes the counterdie 4 of PAR film 1 and ultra-thin import PU film 2 compound composition band vibrating membrane rings 3 successively, honeycomb wood based panel or honeycomb cystosepiment 6 and aluminium foil 7 are adopted in ball top 5 on the counterdie 4, all adopt adhesive 8 bondings between counterdie 4, honeycomb wood based panel or honeycomb cystosepiment 5 and the aluminium foil 7 successively.
Claims (2)
1, composite material vibrating membrane, it is characterized in that upwards including successively the counterdie of PAR film and the compound composition band of PU film vibrating membrane ring, honeycomb wood based panel or honeycomb cystosepiment and aluminium foil are adopted in the ball top, use adhesives successively between counterdie, honeycomb wood based panel or honeycomb cystosepiment and the aluminium foil.
2, composite material vibrating membrane according to claim 1 is characterized in that described PU film is ultra-thin PU film.
