Description

具透明振膜的大音圈扬声器 技术领域  Large voice coil speaker with transparent diaphragm
本发明涉及扬声器， 具体涉及一种大音圈扬声器。  The invention relates to a loudspeaker, in particular to a large voice coil loudspeaker.
背景技术 Background technique
现有的传统锥体低音扬声器和一些新型扬声器如平板扬声器等 均是由振膜的中心连接音圈， 音圈的直径小于振膜直径， 这种从中心 驱动振膜作整体活塞振动的结构形式，由于受振膜刚性及振动质量相 矛盾等因素影响，振膜在作活塞振动时不同程度会产生有害的分割振 动和边环反振， 很难使扬声器音质及性能达到较为理想效果。 此外， 传统锥体低音扬声器的固有结构使其顺性及行程和扬声器的定心支 片有较大关系， 由于定心支片的直径和弹性是有限度的， 而加大音圈 直径将使定心支片的可活动范围减小，从而导致扬声器顺性和行程降 低， 由于音圈相对振膜不能大直径设计， 从而也大大地限制了扬声器 效率、 功率等性能提高。  The existing conventional cone woofer and some new types of speakers, such as flat panel speakers, are connected to the voice coil by the center of the diaphragm, and the diameter of the voice coil is smaller than the diameter of the diaphragm. This structure of driving the diaphragm from the center as a whole piston vibration Due to the contradiction between the rigidity of the diaphragm and the vibration quality, the diaphragm will generate harmful split vibration and side ring vibration when it is vibrating the piston. It is difficult to achieve better sound quality and performance. In addition, the inherent structure of the traditional cone woofer makes its compliant and stroke have a greater relationship with the centering piece of the speaker. Since the diameter and elasticity of the centering piece are limited, increasing the diameter of the voice coil will make The movable range of the centering piece is reduced, resulting in a decrease in the compliantness and stroke of the speaker. Since the voice coil is not designed with a large diameter relative to the diaphragm, the performance of the speaker, such as efficiency and power, is greatly limited.
另外， 现有的扬声器的振膜一般采用非透明材料制成， 在观赏性 和新颖性方面也有所不足， 限制了进一步的应用。  In addition, the diaphragm of the existing speaker is generally made of a non-transparent material, which is also insufficient in terms of ornamental and novelty, which limits further applications.

2、 本发明由于釆用大直径音圈， 能够更加稳定、 有效地对振膜 进行控制， 使其在前后运动时不易发生变形， 从而降低失真率。  2. The present invention can control the diaphragm more stably and effectively by using a large-diameter voice coil, so that it is less likely to be deformed when moving back and forth, thereby reducing the distortion rate.
3、 本发明这种周边驱动结构加大了音圈的直径， 可提高扬声器 的效率和功率。  3. The peripheral drive structure of the present invention increases the diameter of the voice coil and improves the efficiency and power of the speaker.
