The utility model content
It is little that the purpose of this utility model provides a kind of thickness, compact conformation, and the super-thin speaker that effectively guaranteed of tonequality.
For achieving the above object, the technical solution of the utility model is: comprise magnet assembly, voice coil loudspeaker voice coil, the sound film, the sound membrane cover, cover plate, it is characterized in that: described sound membrane cover is a tabular, center, sound membrane cover one side end face is provided with the accommodation chamber that is complementary with magnet assembly, this accommodation chamber bottom is provided with phonate hole, the peripheral position of relative accommodation chamber is provided with the transaudient groove that is connected with phonate hole on the opposite side end face of described sound membrane cover, described cover plate covers on the end face of the transaudient groove of sound membrane cover place one side, described transaudient groove and cover closure form sound channel, and the outlet of this sound channel is located at sound membrane cover sidewall.This is provided with and adopts flat sound membrane cover, and sound channel is arranged on the accommodation chamber periphery, and the loud speaker integral thickness is greatly dwindled.
Further being provided with is that described sound channel is multistage bending forming, and its sectional area increases gradually.By this setting, in limited space, increased sound channel length, sound obtains multistage amplification simultaneously, and tonequality is guaranteed.
Described phonate hole further is set two groups, and each group comprises two phonate holes, and two groups of phonate holes are symmetrical arranged, and two groups of phonate holes respectively are connected with sound channel, and two sound channels are symmetrical arranged.By this setting, sound is from the output of dual track symmetry, and tonequality is further enhanced.
Further being provided with is that described magnet assembly is a round pie, described sound membrane cover cross section is a rectangle, right angle, the junction bending of described sound channel and each group phonate hole converges at a bit, bias is to sound membrane cover one side again, and extend to another adjacent side along this side, the right angle bends and extends to the 3rd side along this side again, and right angle bending and final outlet are in the center of the 3rd side again.
Further being provided with is to be provided with sound film packing ring between described sound film and the magnet assembly.
Further being provided with is the recessed moulding of center sphere of described sound film.By this setting, reduced the interior space requirement of loud speaker, integral thickness is further dwindled.
Further being provided with is that the sound membrane cover sidewall that offers the sound channel outlet is connected with horn outward, and this horn is a tabular, its thickness and sound membrane cover fit, be provided with two horn chambers in it, each horn chamber is connected with sound channel, and by this setting, sound can further amplify in horn.
Further being provided with is that described horn cross section is an isosceles trapezoid.By this setting, the loudspeaker opening increases gradually, and tonequality is further enhanced.
Further being provided with is that described sound membrane cover is an aluminum design.Adopt this setting, the heat of speaker operation effectively distributed, guarantee loud speaker in normal operating conditions.
The beneficial effects of the utility model are thin thickness, and tonequality is good, have solved the problem that space narrow and small occasion can not be used conventional loudspeakers.
Below in conjunction with Figure of description the utility model is done further introduction
