Abstract
The utility model provides a small loudspeaker device which comprises a first unit, a second unit, a first frame surrounding the first unit, a second frame surrounding the second unit, and an acoustic port. The first frame is provided with air channels and includes a plurality of supports and struts; the acoustic port includes a first sound hole and a second sound hole; a first air chamber is formed in the front of a membrane of the first unit and is connected to the first sound hole; and a second air chamber is formed in the front of a membrane of the second unit and is connected to the second sound hole. The periphery of the membrane of the first unit is fixed on the supports of the first frame. The upper ends of the struts of the first frame are connected with the second sound hole in the lower end of the acoustic port. The size of the loudspeaker is reduced, and the sound clarity of the loudspeaker is improved.
Description
Technical field
The utility model relates to loud speaker, especially a kind of miniature loudspeaker device.
Background technology
Along with popularizing of portable music player, earphone is used more and more general, is convenient to people and listens to music in various occasions.For easy to carry, require the earphone size less, so the loud speaker that earphone is used is also more and more less.
Summary of the invention
The purpose of this utility model is: a kind of miniature loudspeaker device is provided.
The technical solution adopted in the utility model is: the utility model provides a kind of miniature loudspeaker device, comprises the first framework of first module, second unit, encirclement first module, the second framework and the acoustical ports of surrounding second unit.The first framework is provided with air duct, comprises some supports and pillar; Acoustical ports comprises the first sound hole and the second sound hole; The diaphragm front of first module forms the first air chamber, is connected to the first sound hole; The diaphragm front of second unit forms the second air chamber, by air duct, connects the second sound hole.
In the utility model, the diaphragm periphery of first module is fixed on the support of the first framework.
In the utility model, the upper end of each pillar of the first framework connects the second sound hole of acoustical ports end portion.
The beneficial effects of the utility model are: reduced speaker size, improved the definition of loudspeaker sound simultaneously.
The accompanying drawing explanation
Fig. 1 is the vertical view of the loud speaker that provides of the utility model.
Fig. 2 is the cutaway view of the loud speaker that provides of the utility model.
Fig. 3 is loud speaker the first framework appearance view that the utility model provides.
Embodiment
As depicted in figs. 1 and 2, the miniature loudspeaker device comprises first module 1a, second unit 1b, the first framework 2 of encirclement first module 1a, the second framework 3 and the acoustical ports 5 of surrounding second unit 1b.The first framework is provided with air duct 4, and acoustical ports 5 comprises the first sound hole 6 and the second sound hole 7.
The diaphragm front of first module 1a forms the first air chamber 8, is connected to the first sound hole 6.Therefore, the sound of front that is radiated the diaphragm of first module 1a is transferred to outside by the first air chamber 8 and the first sound hole 6 successively.The diaphragm front of second unit 1b forms the second air chamber 9, is connected sound hole 7a and 7b with 4b by air duct 4a.Therefore, be radiated the sound of front of diaphragm of first module 1b successively by the second air chamber 9, air duct 4a and 4b, sound hole 7a and 7b.
As 3 are external views of the first framework 2.Air flue 4a and 4b are communicated with the first framework 2 and the second sound hole 7a, 7b.The first framework 2 comprises support 12a, 12b, 12c, 12d and pillar 13a, 13b.The diaphragm periphery of first module 1a is fixed on support 12a, 12b, 12c, 12d.Pillar 13a is connected the second sound hole 7a and 7b of acoustical ports end portion with 13b upper end separately.
The sound of first module and second unit is separated from each other, and from acoustical ports, different sound holes is transferred to outside.The sound of the diaphragm radiation of first module 1a produces first acoustic resonance, and the sound of the diaphragm radiation of second unit 1b produces second acoustic resonance.First sound resonance and rising tone resonance have different frequencies, can improve the definition of sound.
