Abstract
Provided is a super-shallow installation loudspeaker with a magnetic circuit mounted upside-down. The loudspeaker comprises a cone frame (1) and a magnetic circuit system which consists of a high intensity magnet (2), a clamping plate (3) and a piece of U-iron (4). The loudspeaker further comprises an aluminum-quality core column (5) which consists of a bottom plate (5.1) and a convex column (5.2) that is moulded at the center of the bottom plate (5.1), wherein the convex column (5.2) is sleeved inside the cone frame (1); the bottom plate (5.1) is connected with the bottom of the cone frame (1), and the magnetic circuit system is mounted upside-down and is threadedly connected with the top of the convex column (5.2). The super-shallow installation loudspeaker with the magnetic circuit mounted upside-down can satisfy a shallow-installation requirement without affecting driving force performance.
Description
Technical field:
The utility model relates to a kind of loud speaker, specifically is the ultra shallow installation loud speaker of a kind of magnetic circuit flip-over type.
Background technology:
The shape and structure of loud speaker is multifarious at present, but under many situation, when running into the situation that carrier bulk is little and fitting depth is little, the loud speaker of many big fitting depths just can't be installed.If change the clamping plate of thin loud speaker and the thickness of magnet steel, then can cause the actuating force of loud speaker not enough in order to reduce fitting depth.
The utility model content:
The utility model technical issues that need to address are: provide a kind of under the situation that does not influence the actuating force performance, satisfy the ultra shallow installation loud speaker of magnetic circuit flip-over type of shallow installation requirement.
For solving the problems of the technologies described above; The utility model adopts the ultra shallow installation loud speaker of a kind of like this magnetic circuit flip-over type, and it comprises basin frame and the magnetic circuit system that is made up of strong magnetic, clamping plate and U iron, and it also comprises aluminium matter stem stem; Described aluminium matter stem stem is made up of base plate and the projection that takes shape in the base plate center; Described projection is set in the basin frame, and described base plate is connected with the bottom of basin frame, and the top of projection is inverted and is screwed onto to described magnetic circuit system.
The top that projection was inverted and was screwed onto to described magnetic circuit system is meant; Counterbore in described projection is provided with axially; The clamping plate of described magnetic circuit system are provided with and the axially interior coaxial screw hole of counterbore, and the machine tooth screw of described magnetic circuit system counterbore, screw hole in passing axially successively is fastened on the top of projection.
The center at the top of described projection is provided with groove, and the bottom of described clamping plate is provided with the projection that matches with the groove chucking.
Described base plate is connected with the bottom of basin frame and is meant, described base plate through glue in the bottom or the described base plate of basin frame is fastened on the basin frame through screw bottom.
The utility model compared with prior art has the following advantages: the ultra shallow installation loud speaker of the magnetic circuit flip-over type of the utility model is because of having additional the aluminium matter stem stem that is made up of base plate and projection, and wherein projection is set in the basin frame; And base plate is connected with the bottom of basin frame, adds that magnetic circuit system is inverted and is screwed onto the top of projection, like this after assembling; Magnetic circuit system just is positioned at the basin frame, rather than as prior art, is positioned at the below of basin frame, and the loud speaker height after the assembling is compared with the loud speaker height of prior art like this; Differed the height of a magnetic circuit system; Thereby greatly reduce the whole height of whole loud speaker, under the situation of not strong magnetic of attenuate and clamping plate thickness, not only effectively ensured the driveability of loud speaker like this; Simultaneously also greatly reduce whole height, satisfy shallow installation requirement occasion.
As improvement, the center at the top of described projection is provided with groove, and the bottom of described clamping plate is provided with the projection that matches with groove chucking, further fastening magnetic circuit system.
Description of drawings:
Fig. 1 is the sectional structure sketch map of the ultra shallow installation loud speaker of magnetic circuit flip-over type of the utility model.
Fig. 2 analyses and observe the structure for amplifying sketch map for the aluminium matter stem stem among Fig. 1.
