Abstract
This utility model relates to a kind of U ferrum for speaker, and including body, on the upper end of this body, outer extension is shaped with flanging, and described flanging is shaped with an open slot；Described body bottom portion is shaped with passage, it is ensured that radiating effect, improves tonequality, and the inwall of described body is shaped with arcuation annular groove.The setting of open slot is crossed by this U Tie Tong so that the flanging of U ferrum can be overlapped on the hole outer rim of frame, effectively prevents U ferrum from deviating from, improves the quality of loudspeaker.It is shaped with passage bottom this U ferrum, it is ensured that radiating effect, improves tonequality.The inwall of this U ferrum is shaped with arcuation annular groove, by the setting of arcuation annular groove, in the case of ensureing equal volume, increases the gap between U ferrum and Magnet, is effectively increased magnetic flux power, make magnetic circuit more smooth and easy, improve the acoustical quality of speaker.
Description
Technical field
This utility model belongs to loudspeaker techniques field, a kind of U ferrum for speaker.
Background technology
U ferrum is the base of speaker, is part the most important in audio amplifier, and U Tie Tong is often solidly installed with frame, U ferrum
In can place Magnet.
The problem that traditional U ferrum exists following aspect:
1, the top outer rim of U ferrum is shaped with cannelure, is then inlaid in the hole of frame, and this kind of mounting structure easily disengages；
2, poor radiation, during speaker operation, owing to the effect of electric current and coil makes U ferrum generate heat；
3, the gap between Magnet and U ferrum is little, reduces magnetic flux power.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of easy for installation, firmly for speaker
U ferrum.
Scheme of the present utility model is achieved in that
A kind of U ferrum for speaker, including body, on the upper end of this body, outer extension is shaped with flanging, described outside
An open slot it is shaped with on flange；Described body bottom portion is shaped with passage, it is ensured that radiating effect, improves tonequality.
And, the inwall of described body is shaped with arcuation annular groove.
Advantage of the present utility model and good effect be:
1, the setting of open slot is crossed by this U Tie Tong so that the flanging of U ferrum can be overlapped on the hole outer rim of frame, effectively prevents
U ferrum is deviate from, and improves the quality of loudspeaker.
2, it is shaped with passage bottom this U ferrum, it is ensured that radiating effect, improves tonequality.
3, the inwall of this U ferrum is shaped with arcuation annular groove, by the setting of arcuation annular groove, in the case of ensureing equal volume,
Increase the gap between U ferrum and Magnet, be effectively increased magnetic flux power, make magnetic circuit more smooth and easy, improve speaker
Acoustical quality.
4, this utility model simple in construction, design science rationally, be skillfully constructed, low cost, make magnetic circuit more smooth and easy, carry
The high acoustical quality of speaker, has the value of wide popularization and application.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is that the A-A of Fig. 2 is to sectional view.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment.
A kind of U ferrum for speaker, as shown in Figure 1 and Figure 2, including body 2, outer extension on the upper end of this body
It is shaped with flanging 1.
Innovative point of the present utility model is:
1, it is shaped with an open slot 3 on described flanging, screws in the breach that frame is shaped with by this open slot is convenient, this U
The flanging of ferrum can be overlapped on the hole outer rim of frame, effectively prevents U ferrum from deviating from, improves the quality of loudspeaker.
2, described body bottom portion is shaped with passage 4, it is ensured that radiating effect, improves tonequality.
3, the inwall of described body is shaped with arcuation annular groove 5, as it is shown on figure 3, by the setting of arcuation annular groove, same in guarantee
In the case of isopyknic, increase the gap between U ferrum and Magnet, be effectively increased magnetic flux power, make magnetic circuit more smooth and easy,
Improve the acoustical quality of speaker.
It is emphasized that embodiment described in the utility model is illustrative rather than determinate, therefore this practicality
The novel embodiment including being not limited to described in detailed description of the invention, every by those skilled in the art according to this utility model
Other embodiments of drawing of technical scheme, also belong to the scope of this utility model protection.
