Abstract
The utility model relates to the technical field of speakers, in particular to an external magnetic structural speaker which comprises a magnet, a magnetic pole piece and a base; the magnet is sleeved outside the magnetic pole piece; the magnet and the magnetic pole piece are arranged on the base and are fixed by a T-shaped iron; the lower end of the base is provided with a vibration diaphragm, a protective cover and a dustproof mesh; and the external magnetic structural speaker has the advantages of scientific and simple structural design, small size, external structure and high volume.
Description
Technical field:
The utility model relates to the loudspeaker technical field, refers in particular to a kind of external magnetic type structure loudspeaker.
Background technology:
At present, make the field at loudspeaker, existing loudspeaker, as shown in Figure 2: internal magnetization thorn the structure that generally adopts voice coil loudspeaker voice coil 2A induced signal, its magnetic flux leakage is big, and volume is too small, and the volume of magnet ring 1A and voice coil loudspeaker voice coil 2A2A is excessive, magnet ring 1A, voice coil loudspeaker voice coil 2A are installed on the pedestal 3A, are unfavorable for the application of some precise electronic products; Simultaneously, production cost is higher.
The utility model content:
The purpose of this utility model is at the deficiencies in the prior art, and a kind of external magnetic type structure loudspeaker are provided, and its scientific structure design is simple, and volume is little, adopts external magnetic type structure, gives great volume.
For achieving the above object, the utility model adopts following technical scheme, and it comprises magnet, pole piece, pedestal, and magnet is enclosed within the outside of pole piece, magnet, pole piece are installed on the pedestal and by the ferropexy of T shape, the lower end of pedestal is equipped with vibrating membrane, protecting cover, Air Filter.
Described magnet is annular magnet.
Offer through hole on the described pedestal, the upper end is provided with the tuning screen cloth.
The utility model beneficial effect is: magnet, pole piece are installed on the pedestal and by the ferropexy of T shape, its scientific structure design is simple, and volume is little, adopts external magnetic type structure, gives great volume, and can be used for the application of some precise electronic products; Simultaneously, production cost is low.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the rigging position cutaway view of prior art;
Fig. 3 is the utility model rigging position cutaway view;
Fig. 4 is a decomposition texture schematic diagram of the present utility model.
Embodiment:
See shown in Fig. 1,3,4: the utility model comprises magnet 1, pole piece 2, pedestal 3, magnet 1 is enclosed within the outside of pole piece 2, magnet 1, pole piece 2 are installed on the pedestal 3 and by T shape iron 11 and fix, the lower end of pedestal 3 is equipped with vibrating membrane 6, protecting cover 7, Air Filter 8, is connected with pcb board 4 on the pedestal 3.
Described magnet 1 is annular magnet.
Offer through hole 31 on the described pedestal 3, the upper end is provided with tuning screen cloth 5.
Contrast the scheme in the present technology, shown in Figure 2; Internal magnetization thorn the structure of voice coil loudspeaker voice coil 2A induced signal, its magnetic flux leakage is big, and volume is too small, and the volume of magnet ring 1A and voice coil loudspeaker voice coil 2A is excessive, and magnet ring 1A, voice coil loudspeaker voice coil 2A are installed on the pedestal 3A, are unfavorable for the application of some precise electronic products; Simultaneously, production cost is higher.
The utility model is enclosed within the outside of pole piece 2 with magnet 1, and as shown in Figure 3: volume is little, adopts external magnetic type structure, gives great volume, and can be used for the application of some precise electronic products; Simultaneously, production cost is low.
Afterbody day of the present utility model, pcb board 4 was welded with two leads that connect signal.
The above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
