Abstract
The utility model relates to a belt type loudspeaker, particularly a super-high-frequency multi-belt parallelly arranged belt type loudspeaker which comprises a loudspeaker panel. The belt type loudspeaker is characterized in that the utility model is provided with a groove-shaped outer pole plate of which the cross section forms a U shape, and at least one rectangular inner pole plate is arranged in the length direction of the upper opening of the outer pole plate; a magnetic iron is arranged between the bottoms of the inner pole plate and the outer pole plate. Both sides of the inner pole plate are all provided with a belt-shaped voice membrane of which both ends are provided with a wire connecting terminal. The lateral dimension of a single voice membrane of the utility model is smaller than traditional belt type loudspeakers, so that the upper limiting frequency of the belt type loudspeaker exceeds that of the traditional belt type loudspeakers. The effective working area of the voice membrane is greater than the traditional belt type loudspeakers, so that the sensibility and the lower limiting frequency as well as the bearing power of the belt type loudspeaker are all superior to that of the traditional belt type loudspeakers, and the audio quality effect of the utility model is obviously enhanced.
Description
Technical field
The utility model relates to a kind of ribbon speaker, and especially a kind of hyperfrequency is with ribbon speaker arranged side by side more.
Background technology
The conventional belt loud speaker is that a metal tape such as an aluminium strip as thin as a wafer places the rectangle magnetic gap as the sound film, for obtaining enough sensitivity and lower frequency limit, the common broad of metal tape.So just limited the upper limiting frequency of this loud speaker.Because the width of metal tape is narrower, upper limiting frequency is just higher, otherwise then lower.And the width of the metal tape narrow vibration area sluggishness of healing of healing is just lower because sensitivity with vibrate area and be directly proportional.The upper frequency limit of conventional metals band loud speaker and sensitivity constitute contradiction in view of the above.Therefore conventional metals band loud speaker is difficult to work in hyper band.
Summary of the invention
The purpose of this utility model is to provide a kind of can work in hyper band, and enough sensitivity is arranged, and the lower frequency limit of appropriateness and the ribbon speaker of load power are arranged.
The utility model comprises Speaker panel, it is characterized in that being provided with the flute profile external polar plate of a cross section for " U " shape, the length direction at this external polar plate place suitable for reading is provided with the internal polar plate of at least one rectangle, be provided with magnet between internal polar plate and the external polar plate bottom, the both sides of above-mentioned interior step are equipped with strip metal sound film, and there is binding post at banded sound film both ends.
Preferably be provided with densely covered striped on the above-mentioned banded sound film, described striped is preferably V-shaped even distribution on the sound film.
The level and smooth coupling of sound wave for each banded sound film is produced reduces distortion, and the top of above-mentioned interior step preferably is provided with the interband coupling device, and this coupling device is and internal polar plate strip in the same way, the taper of its cross section for upwards shrinking.
Above-mentioned banded sound film number is that internal polar plate is counted N+1.
Sound film of the present utility model can be made of a plurality of narrower banded sound film and corresponding magnetic circuits, its single sound film lateral dimension is less than the conventional belt loud speaker, so its upper limiting frequency surpasses the conventional belt loud speaker, again because of its by a plurality of narrow dimension sound film homophase parallel operations, the effective work area of sound film is greater than the conventional belt loud speaker, so its sensitivity and lower frequency limit and load power all are better than the conventional belt loud speaker, so acoustical quality is significantly improved.
Description of drawings
Fig. 1 is the structural representation of embodiment 1.
The structural representation that Fig. 2 overlooks for Fig. 1.
Fig. 3 is the structural representation of embodiment 2.
Diagram 1 is a Speaker panel, and 2 is external polar plate, and 3 is banded sound film, and 4 is the interband coupling device, and 5 is internal polar plate, and 6 is magnet, and 7 is binding post.
Embodiment
Embodiment 1:
With reference to Fig. 1, Fig. 2, an internal polar plate is arranged in the external polar plate, the both sides aluminium strip sound film of interior step, there is binding post at sound film both ends, banded sound film is provided with longitudinally equally distributed " V " shape striped, and interior step is provided with the interband coupling device, and this coupling device is and internal polar plate strip in the same way, its cross section is a triangle, and promptly two waists are the plane.
Embodiment 2:
With reference to Fig. 3, to compare with embodiment 1, the difference of present embodiment is that external polar plate is provided with two internal polar plates and three aluminium strip sound films, and the cross section of coupling device is that two waists are the taper of arc, and promptly two waists are cambered surface.
Claims (7)
