The utility model proposes a kind of top dome high pitch loudspeaker。

It it is the top view of this utility model top dome high pitch loudspeaker one embodiment referring to figs. 1 through 5, Fig. 1；Fig. 2 is the decomposing state schematic diagram of top dome high pitch loudspeaker in Fig. 1；Fig. 3 be in Fig. 1 top dome high pitch loudspeaker along the sectional view of line A-A；Fig. 4 is the assembling orientation diagram of top dome vibrating diaphragm, supporting construction and magnetic conductor in Fig. 2；Fig. 5 is the perspective view of magnetic conductor and supporting construction in Fig. 2。

In this utility model embodiment, this top dome high pitch loudspeaker 10 includes top dome vibrating diaphragm 12 and magnetic conductor 11, a supporting construction 13 it is provided with between magnetic conductor 11 and top dome vibrating diaphragm 12, supporting construction 13 includes a hemispherical Shell 130, the edge 132 of hemispherical Shell 130 medial surface abuts with magnetic conductor 11, and the spherical outside surface 131 of hemispherical Shell 130 abuts with top dome vibrating diaphragm 12。

The technical solution of the utility model by setting up a supporting construction 13 between magnetic conductor 11 and top dome vibrating diaphragm 12, effectively prevent top dome vibrating diaphragm 12 to be pressed and cave in or situation about deforming occurs, the acoustical behavior preventing top dome high pitch loudspeaker 10 reduces, and also improves the service life of top dome high pitch loudspeaker 10。

Specifically, traditional top dome high pitch loudspeaker 10 includes U ferrum 14, U ferropexy frame 17, voice coil loudspeaker voice coil 15, magnet 16, magnetic conductor 11, top dome vibrating diaphragm 12 and high pitch panel 18, it is provided with viscose glue in U ferrum 14, the one side of magnet 16 is fixed in U ferrum 14 by viscose glue, being also equipped with viscose glue on magnet 16, magnetic conductor 11 is fixed on the another side of magnet 16 by this viscose glue, and top dome vibrating diaphragm 12 abuts with magnetic conductor 11, voice coil loudspeaker voice coil 15 also is secured in U ferrum 14, and this voice coil loudspeaker voice coil 15 is set in the periphery of magnet 16。This assembly is installed on high pitch panel 18 after being assembled into an assembly by U ferrum 14, voice coil loudspeaker voice coil 15, magnet 16, magnetic conductor 11, top dome vibrating diaphragm 12, then passes through U ferropexy frame 17 and is fixed on high pitch panel 18 by this assembly。

At this, it is necessary to explanation, hemispherical Shell 130 is not the half only referring only to spheroid, it is also possible to be less than the half of spheroid。Magnetic conductor 11 is generally iron plate, and its effect is the density and the direction that control magnetic flux, increases magnetic induction。When being arranged between magnetic conductor 11 and top dome vibrating diaphragm 12 by this hemispherical Shell 130, the spherical outside surface 131 of hemispherical Shell 130 abuts with top dome vibrating diaphragm 12, such that it is able to prevent from deforming because of top dome vibrating diaphragm 12 pressurized or caving in。

In order to reduce the supporting construction 13 impact on sounding effect, in the present embodiment, hemispherical Shell 130 is in netted setting。

Specifically, having a cavity between magnetic conductor 11 and top dome vibrating diaphragm 12, the size of this cavity is relevant to the Q-value of this top dome high pitch loudspeaker 10, once in this cavity after extension supporting structure 13, the volume of cavity is reduced by, corresponding Q-value also can change。If Q-value changes greatly, then result in sounding effect and be deteriorated。And in the present embodiment, the netted setting of hemispherical Shell 130 just reduces the space occupancy of hemispherical Shell 130 self, therefore, hemispherical Shell 130 affects greatly without to Q-value。

Consider that supporting construction 13 self structurally also needs to strengthen, so that the support effect of hemispherical Shell 130 is more preferably, in the present embodiment, supporting construction 13 includes at least one support rod 133 for abutting being arranged in hemispherical Shell 130 with magnetic conductor 11, and support rod 133 connects the edge 132 of hemispherical Shell 130。The quantity of support rod 133 can be one, two, three or more, the rounded setting in edge 132 of hemispherical Shell 130, if the quantity of support rod 133 is one, this support rod 133 circular edges along 132 radially extend effect preferably；If the quantity of support rod 133 is two, two support rods 133 all radially extend effect preferably；If the quantity of support rod 133 is three, three support bars 133 constitute a triangle, and effect is preferably。

On the basis of a upper embodiment, it is contemplated that the support effect of space occupancy and support rod 133, in the present embodiment, the quantity of support rod 133 is two, and two support rods 133 are in arranged in a crossed manner。

Two support rods 133 arbitrarily intersect, but in order to make the stress when supporting of support rod 133 evenly, two support rods 133 all in circular edges along 132 radially extend, and two muscle stays 133 are that " ten " word arranges effect preferably。

The fixed form of hemispherical Shell 130 and magnetic conductor 11 has multiple, such as bonding, riveted joint etc., in order to increase the stability that hemispherical Shell 130 is installed in cavity further, in the present embodiment, support rod 133 infall has local to extend to form protruding 134, and magnetic conductor 11 is provided with the shrinkage pool 111 corresponding and adaptive with these protruding 134 positions；Or, support rod 133 is provided with shrinkage pool 111, magnetic conductor 11 is provided with the projection 134 corresponding and adaptive with this shrinkage pool 111 position。

So, after supporting construction 13 can being coordinated with shrinkage pool 111 by protruding 134 with magnetic conductor 11, supporting construction 13 is also produced multi-faceted abutting power by magnetic conductor 11, and the support degree making supporting construction 13 is bigger。

On the basis of a upper embodiment, protruding 134 more stable with coordinating of groove in order to make, in the present embodiment, projection 134 and shrinkage pool 111 setting all in a cross-shaped mode。

The material of supporting construction 13 can not be permeability magnetic material, for instance, it is impossible to it is ferrum, nickel etc., in order to avoid affecting speaker sounding。In one embodiment, supporting construction 13 is made up of nonmetallic materials or non-magnetic metal material。Such as, the material of making of described supporting construction 13 is PC material, pottery, aluminum etc.。

These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every under inventive concept of the present utility model; utilize the equivalent structure transformation that this utility model description and accompanying drawing content are made, or directly/be indirectly used in other relevant technical fields and be included in scope of patent protection of the present utility model。
