Description
Technical Field
The utility model relates to a loudspeaker, in particular to a track-shaped loudspeaker and a track-shaped damper thereof.
Background
With the continuous development and growth of home theater products, the market occupation ratio of SoundBar products is continuously improved, but the SoundBar is limited in height due to the influence of the height of a television bracket, people want to pursue the sound quality effects of large sound and low distortion, the traditional circular horn is difficult to meet the requirements due to the limited structure size, and the non-circular loudspeaker is produced. The radiating area of the unit can be increased by adopting the runway or the oval loudspeaker, and meanwhile, the magnet can also adopt a square shape to overcome the difficulty of structural limitation, so that the magnetic field intensity of the whole magnetic circuit system is increased, and the effect of improving the sensitivity of the loudspeaker is achieved.
However, the adoption of new technologies often brings new problems, such as: when we consider using a racetrack speaker, it is often difficult to place a circular centering disk (spider) in the short axis direction because the width is too small, and this time we have to consider using: firstly, cutting off ripples in the short axis (longitudinal) direction by adopting a circular elastic wave, and keeping the ripples in the long axis (transverse) direction; secondly, a runway-shaped elastic wave is adopted.
The symmetry of the whole vibration system is better in the first method with respect to the second method, but it has two fatal problems: 1. the short axis direction lacks a positioning function, and the voice coil can deviate when the loudspeaker works, so that abnormal sound of the touch coil can be generated; 2. after cutting off a part of ripple, the tensile strength of bullet ripples receives the influence, leads to the bullet ripples to stretch out to split easily when the high-power work of speaker.
The second method perfectly solves the two fatal problems of the first method, as compared with the first method, and although its symmetry is relatively poor and the distortion of the speaker is slightly higher in the low frequency part than in the first method, the second method is certainly a better choice from the viewpoint of safety.
However, the racetrack-shaped damper has a problem that the corrugation width is not uniform in the major axis direction and the minor axis direction, and the corrugation width is large in the major axis direction and small in the minor axis direction. When the loudspeaker works, because the width of the ripple in the long axis direction is large, the elastic ripple is easy to generate the phenomenon of reverse folding, thereby leading to abnormal sound of the loudspeaker.
