Description

Miniature loudspeaker monomer

Technical field

The utility model is a kind of related miniature loudspeaker monomer, espespecially a kind of to use the better simply ellipse of moulding process The design of the voice coil collocation vibration biggish rectangular vibrating diaphragm of area.

Background technique

It can be increased the output volume of loudspeaker due to increasing vibrating diaphragm area, and comparison length and rectangular vibration of same size Film and oval vibrating diaphragm, the area of rectangular vibrating diaphragm certainly will be greater than the area of oval vibrating diaphragm, but because rectangular voice coil moulding process compared with Ellipse or circular voice coils are difficult, therefore common miniature loudspeaker framework is still using the oval oval vibrating diaphragm of voice coil collocation.

Utility model content

Technical problem underlying to be solved in the utility model is, overcomes drawbacks described above of the existing technology, and mentions For a kind of miniature loudspeaker monomer, has and rectangular vibrating diaphragm is arranged in pairs or groups so as to increasing loudspeaker output volume using oval voice coil Effect；Have effects that balance vibrating diaphragm movement and reduce and polarization distortion occurs.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of miniature loudspeaker monomer a, comprising: pedestal is combined with the double-sided PCB of a pair of of positional symmetry, and allows this The top surface of double-sided PCB is revealed in inside the pedestal, and is revealed in the bottom surface to double-sided PCB outside the pedestal； One magnetic returns structure is incorporated into the pedestal and has magnetic gap；One rectangular vibrating diaphragm has a rectangular outer portion and a square central Portion, and the outer rim of the rectangular central part is incorporated into the inner edge of the rectangular outer portion, and the outer rim of the rectangular outer portion is combined In the pedestal；And an oval voice coil, it is incorporated into below the square central portion of the rectangular vibrating diaphragm and is located in the magnetic gap, it should Oval voice coil is electrically connected to the top surface to double-sided PCB by a pair of of bright and beautiful silk thread, and enables this to bright and beautiful silk thread outlet direction It is opposite but symmetrical.

In addition, the rectangular central part has an oval central massif and an outer ring flat region, the outer ring flat region Inner edge is ellipse and outer rim is rectangular, and the ellipse voice coil is enabled to be incorporated at the inner edge of the outer ring flat region；However, the seat Body with respect to this to bright and beautiful silk thread and this to double-sided PCB be equipped with couple of conductor slot, wherein the pedestal is equipped with metallic channel with respect to this A pair of of bright and beautiful silk thread perforation；Also, this, which perforates to bright and beautiful silk thread, further inserts sealing.

Furthermore the ellipse voice coil has oval skeleton and oval coil；This electrically connects double-sided PCB bottom surface Connect external signal line；This is incorporated into the pedestal to double-sided PCB integrated molding.

Whereby, using the better simply oval voice coil collocation vibration biggish rectangular vibrating diaphragm of area of moulding process, Jin Erzeng Add loudspeaker output volume, and pairs of bright and beautiful silk thread outlet direction is opposite but symmetrically designs, and vibration vibration of membrane can be made more flat Weighing apparatus.

The utility model has the beneficial effects that it, which has, arranges in pairs or groups rectangular vibrating diaphragm so as to increasing loudspeaker using oval voice coil The effect of output volume；Have effects that balance vibrating diaphragm movement and reduce and polarization distortion occurs.

Specific embodiment

Firstly, please referring to shown in FIG. 1 to FIG. 4, the utility model includes: a pedestal 10, and integrated molding is combined with a contraposition Symmetrical double-sided PCB 11 is set, and allows the top surface to double-sided PCB 11 to be revealed in inside the pedestal 10, and make this to double The bottom surface of face circuit board 11 is revealed in outside the pedestal 10, convenient for being electrically connected external signal line；It should however, the pedestal 10 is opposite Couple of conductor slot 12 and a pair of of bright and beautiful silk thread perforation 13 are equipped with to double-sided PCB 11；One magnetic returns structure 20 is incorporated into the pedestal 10 And there is magnetic gap；One rectangular vibrating diaphragm 30 has a rectangular outer portion 31 and a square central portion 32, which has There are an oval central massif 321 and an outer ring flat region 322, the inner edge of the outer ring flat region 322 is oval and outer rim To be rectangular, and the outer rim of the outer ring flat region 322 is incorporated into the inner edge of the rectangular outer portion 31, and by the rectangular outer portion 31 Outer rim be incorporated into the pedestal 10；And an oval voice coil 40, it is incorporated into the outer of the square central portion 32 of the rectangular vibrating diaphragm 30 It encloses lower section at 322 inner edge of flat region and is located in the magnetic gap, which is electrically connected by a pair of of bright and beautiful silk thread 41 To the top surface to double-sided PCB 11, and enable this opposite to 41 outlet direction of bright and beautiful silk thread but symmetrical, and the ellipse voice coil 40 With oval skeleton and oval coil.

Whereby, the mode that the utility model is electrically connected is this to be positioned at this to metallic channel 12 to bright and beautiful silk thread 41, and wear Out this to bright and beautiful silk thread perforation 13, facilitating welding personnel to hold this from the pedestal 10 fixes it metallic channel 12, then by this to leading Wire casing 12 is welded in the top surface to double-sided PCB 11, completes internal electric connection, then moderate pruning this to bright and beautiful silk thread 41 and further in this to 13 filling sealings of bright and beautiful silk thread perforation, realize the function of loudspeaker waterproof, and this is to double-sided PCB 11 Bottom surface be revealed in outside the pedestal 10, then convenient for being electrically connected external signal line, complete external electric connection.

Based on above-mentioned composition, the utility model is arranged in pairs or groups oval voice coil 40 using rectangular vibrating diaphragm 30, and rectangular vibrating diaphragm 30 has There are rectangular outer portion 31 and square central portion 32, square central portion 32 further has oval central massif 321 and outer ring Flat region 322, and enable that the inner edge of outer ring flat region 322 is ellipse and outer rim is rectangular, and oval voice coil 40 is incorporated into Lower section at the oval inner edge of outer ring flat region 322；Therefore, the better simply oval voice coil of moulding process not only can be used, also The assortable vibration biggish rectangular vibrating diaphragm of area, and have defeated so as to increasing loudspeaker using the rectangular vibrating diaphragm of oval voice coil collocation Out the effect of volume.Furthermore pairs of 41 outlet direction of bright and beautiful silk thread is opposite but symmetrically designs, and vibration vibration of membrane can be made more flat Weighing apparatus has effects that balance vibrating diaphragm movement and reduce and polarization distortion occurs.

The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model Limitation, it is made by the above technical examples according to the technical essence of the present invention it is any it is simple modification, equivalent variations with Modification, is still within the scope of the technical solutions of the present invention.
