The problem of two horn unit frequency range crosspoints needs to be solved in the mode that current well high frequency loudspeaker unit cooperation low frequency loudspeaker unit collocation mode, or high frequency loudspeaker unit cooperation well low frequency loudspeaker unit, and this position needs to include partly frequency range point jointly to avoid missing at the crosspoint and lead to the problem that certain frequency point sound of music is more difficult to hear.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a loudspeaker unit cavity structures with solve the limited problem of high frequency cavity to solve the current well high frequency loudspeaker unit cooperation low frequency loudspeaker unit collocation mode that proposes in the above-mentioned background art, or the mode of low frequency loudspeaker unit in the high frequency loudspeaker unit cooperation, need solve the problem of two loudspeaker unit frequency range crosspoints, this position need include partly frequency range point jointly, thereby avoid leading to the more difficult problem of listening of a certain frequency point sound of music in the crosspoint disappearance.
In order to achieve the above object, the utility model provides a following technical scheme:
a loudspeaker unit cavity structure capable of solving the problem of high-frequency cavity limitation comprises a flexible top cover, a breathable film, an outer shell, a loudspeaker unit and a terminal wire, wherein the flexible top cover is arranged in the middle of the top of the outer shell; the breathable film is arranged on one side of the flexible top cover; the loudspeaker unit; the terminal line is electrically connected with the loudspeaker unit.
As a further technical proposal of the utility model, a soft material attaching hole is perforated from top to bottom in the middle of the outer shell; the flexible top cover is buckled above the flexible material attaching hole.
As a further technical proposal of the utility model, one side of the soft material fitting hole is provided with a horn terminal threading hole; the terminal line is arranged in the loudspeaker terminal threading hole.
As a further technical scheme of the utility model, one side of the soft material fitting hole, which is far away from the horn terminal threading hole, is provided with an air permeable film hole; and a breathable film is arranged above the breathable film hole.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses, high frequency to the intermediate frequency, the wavelength that corresponds is longer and longer more, the distance that corresponds the space of required reflection is also longer more, open a soft material laminating hole in one side of shell body, and paste on soft material laminating hole and have soft top cap, on the long sound wave of length that corresponds transmits soft top cap, soft top cap absorbs the sound wave and rebounds, form the sound of corresponding frequency channel, thereby increase this same size cavity, and can support the sound of lower limit lower frequency, support the sound of the well high frequency range of wideer;
2. the utility model has no change in the middle-high frequency or high-frequency outer shell, and can be used for solving the problem that the middle-high frequency or high-frequency loudspeaker unit limits the range of the sound frequency section because the cavity is easily limited for products which can not increase the size of the cavity of the middle-high frequency or high-frequency loudspeaker unit; thereby avoiding the situation that some good appearance design can not continuously promote the follow-up production.
