Description

A full-range speaker

技术领域technical field

本实用新型涉及音响设备，具体说是一种全频喇叭。The utility model relates to audio equipment, in particular to a full-frequency loudspeaker.

背景技术Background technique

现有的全频喇叭中，其鼓纸外沿整圈均与支架粘合，由于鼓纸长轴方向的两端离音圈中心较远，能量传输损失较大，且粘合后会在鼓纸振动时形成与音圈中心处鼓纸相差较大的阻尼，造成鼓纸长轴和短轴方向的振动不均匀、不一致，导致最终效率不高，且低频效果不能较好的体现出来，降低了喇叭的灵敏度和低频特性。In the existing full-range speaker, the outer edge of the drum paper is bonded to the bracket. Since the two ends of the drum paper in the long axis direction are far from the center of the voice coil, the energy transmission loss is relatively large, and after bonding, it will be in the drum. When the paper vibrates, it forms a damping that is quite different from the drum paper at the center of the voice coil, resulting in uneven and inconsistent vibrations in the long and short axis directions of the drum paper, resulting in low final efficiency, and the low-frequency effect cannot be well reflected, reducing the The sensitivity and low frequency characteristics of the speaker are improved.
