Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done further detailed description.
As depicted in figs. 1 and 2, the loud speaker module comprises peripheral frame and is contained in the interior loudspeaker monomer of peripheral frame, described peripheral frame comprises upper casing 11, mesochite 12 and lower casing 13, loudspeaker monomer involving vibrations system and magnetic circuit system, described loudspeaker monomer secure bond is between mesochite 12 and lower casing 13.The vibrational system of loudspeaker monomer comprises vibrating diaphragm 21 and the voice coil loudspeaker voice coil 20 that is incorporated into vibrating diaphragm 21 downsides, and magnetic circuit system comprises from top to bottom washer 22, magnet 23 and the magnetic conductive board 24 of combination successively.
The present embodiment vibrating diaphragm 21 is incorporated into the upper surface of mesochite 12, vibrating diaphragm 21 upsides are surrounded the front operatic tunes of loud speaker module by upper casing 11, mesochite 12 and loudspeaker monomer, vibrating diaphragm 21 downsides are surrounded the rear operatic tunes of loudspeaker monomer by loudspeaker monomer, mesochite 12 and lower casing 13, the front operatic tunes and the rear operatic tunes are the structure of space.For the ease of the slimming of loud speaker module, lower casing 13 is provided with expects the resettlement section of accommodating magnetic conductive board 24 that forms, and the present embodiment resettlement section is the structure that hollows out, and the shape of resettlement section is corresponding with magnetic conductive board 24.The loud speaker module of this structure, lower casing 13 does not take up room on the vertical direction that affects loud speaker module thickness, thereby be conducive to reduce the height (thickness) of loud speaker module, perhaps in the situation that the volume of the certain raising of loud speaker module height loudspeaker monomer, thereby can guarantee acoustical behavior and the power output of product.In the present embodiment, the rear operatic tunes is positioned at the side of loudspeaker monomer, and magnet 23 corner openings are to be communicated with loudspeaker monomer inboard and the rear operatic tunes, and the rear operatic tunes is positioned at the side and does not take equally the height of loud speaker module vertical direction, is conducive to the slimming of product.
Wherein the outlet sound mouth 120 of loud speaker module is positioned at the side of loud speaker module, outlet sound mouth 120 is positioned at sound that the side can make the loud speaker module from the side radiation of electronic installation out, be positioned at a side over against vibrating diaphragm 21 with the outlet sound mouth of traditional structure loud speaker module, the structure that is positioned at electronic installation front or bottom surface is compared, the outlet sound mouth that can avoid causing due to keeping flat of electronic installation stops up, so practicality is higher.
Position over against vibrating diaphragm 21 on upper casing 11 of the present invention is provided with inner with the extraneous openend 110 of cavate connection loudspeaker monomer, the area of openend 110 is greater than the area of vibrating diaphragm 21, and can comprise vibrating diaphragm 21 in 110 orthographic projections in the plane of openend, bump with upper casing 11 in vibrating diaphragm 21 vibration processes preventing.The structure of this set openend 110, be conducive to increase the size of loudspeaker monomer, more precisely, can provide for the vibration of vibrating diaphragm 21 and dodge the space, this structure guarantees the acoustical behavior of product in the situation that the less size that can guarantee loudspeaker monomer of the thickness of loud speaker module.In addition, openend is not limited to this structure that arranges on upper casing 11, also other distortion can be arranged, and for example, openend can be also the upper end of mesochite 12, and namely the loud speaker module does not arrange upper casing 11, and the position at whole upper casing 11 places is the openend of loud speaker module.
As shown in Figure 3 and Figure 4, the upside of openend 110 is provided with board 3, board 3 is the structure of terminal electronics inside, board 3 and loud speaker module sealing combination, thereby formed the front operatic tunes of loud speaker module by vibrating diaphragm 21, mesochite 12, upper casing 11 and the board 3 of loudspeaker monomer, the front operatic tunes is connected with the outlet sound mouth 120 of side.Wherein, board 3 and the structure of openend 110 for mutually agreeing with are to guarantee both sealing combinations.
As shown in Figure 6, board 3 directly is incorporated into upper casing 11 upper surfaces by modes such as gluings, and board 3 covers the zone at openend 110 places, and sealed open end 110.The sound that vibrating diaphragm 21 produces is transferred to outlet sound mouth 120 outsides via the front operatic tunes I's of upside.Structure shown in Figure 7 is compared the foam 4 of the sealing of having added ring-type with Fig. 6, as shown in Figure 8, foam 4 is arranged at upper casing 11 upper surfaces and openend 110 adjoining positions, foam 4 is set can further increase the sealing of board 4 and loud speaker module, anti-leak-stopping sound, in addition, the oscillation space of vibrating diaphragm 21 also comprises the height of foam 4.
Fig. 9 and Figure 10 are loud speaker module of the present invention structural representation under the use state in electronic installation, in figure, electronic installation is take mobile phone as example, it is only simple signal, as shown in the figure, board 3 is the structure of electronic installation inside, as wiring board or display screen etc., openend on loud speaker module upper casing 11 is formed the front operatic tunes of loud speaker module by board 3 sealings, the outlet sound mouth 120 of loud speaker module side and the shell 5(of electronic installation are only simple signal) on the sound hole corresponding, the side that board 3 is installed the loud speaker module can be installed other electronic components 6, as shown in the figure, this mounting means of loud speaker module does not have the extra space that takies electronic installation inside.
The loud speaker module of this structure, the height of loud speaker module only comprises the height of loudspeaker monomer, the peripheral frame of module and cavity are affecting vacant any space on the vertical direction of its thickness, and the front operatic tunes and the rear operatic tunes are separated, thereby not needing to reduce the size of loudspeaker monomer when the loud speaker module is thinner, the slimming that has namely realized the loud speaker module has also guaranteed acoustical behavior and the power output of loud speaker module.Equally, the loud speaker module of this structure and board sealing form its front operatic tunes, can not increase the thickness of loud speaker module and electronic installation, and take full advantage of the space of electronic installation inside, realize that namely the slimming of electronic installation has guaranteed again its acoustical behavior and power output.
Under above-mentioned instruction of the present invention; those skilled in the art can carry out other improvement and distortion on the basis of above-described embodiment; and these improvement and distortion; all drop in protection scope of the present invention; those skilled in the art should be understood that; above-mentioned specific descriptions are just better explained purpose of the present invention, and protection scope of the present invention is limited by claim and equivalent thereof.
