Description
本發明係關於一種揚聲器結構,尤指一種可讓音圈即使在較大的振動行程下仍能維持垂直方向的作動,以減少音圈水平偏移所導致的各種問題者。The present invention relates to a speaker structure, and more particularly to a method that allows the voice coil to maintain a vertical motion even under a large vibration stroke to reduce various problems caused by the horizontal shift of the voice coil.
揚聲器大致可區分為振動結構及固定結構,振動結構係指揚聲器在外部輸入之音源訊號並轉換成機械振動的過程中,實際產生振動的各個元件,包含音圈及振膜等元件,而固定結構則是指在振動的過程中,不會實質產生振動的元件,包含支架、磁鐵、導磁鐵件等。當輸入之電子訊號的電能愈大,揚聲器的功率就愈大,音圈的振動行程也會愈大,因而振膜的振動行程也會愈大,產生的音量就愈大。因此,揚聲器若要發出大音量,音圈的振動行程必然很大。然而,由於音圈作動時,應當維持在一個軸向上進行往復式作動,但當揚聲器的功率愈大時,音圈作動就容易偏離軸心而導致偏振,輕者聲音失真,重者可能碰觸揚聲器其他組件產生異音,甚至導致損毀。The speaker can be roughly divided into a vibrating structure and a fixed structure. The vibrating structure refers to each component that actually generates vibration during the process of converting the sound source signal input by the speaker into a mechanical vibration, including components such as a voice coil and a diaphragm, and the fixed structure. It refers to an element that does not substantially vibrate during vibration, and includes a bracket, a magnet, a magnetizer, and the like. When the input power of the electronic signal is larger, the power of the speaker is larger, and the vibration stroke of the voice coil is larger, so that the vibration stroke of the diaphragm is larger, and the volume generated is larger. Therefore, if the speaker is to emit a large volume, the vibration stroke of the voice coil must be large. However, since the voice coil is actuated, it should be maintained in one axial direction for reciprocating operation, but when the power of the speaker is larger, the voice coil is easy to deviate from the axis and cause polarization, and the light is distorted, and the heavy one may touch. Other components of the speaker produce an abnormal sound and even cause damage.
因此,如何發明出一種揚聲器結構,以使其可讓音圈即使在較大的振動行程下仍能維持垂直方向的作動,以減少音圈水平偏移所導致的各種問題,將是本發明所欲積極揭露之處。Therefore, how to invent a speaker structure so that the voice coil can maintain the vertical direction even under a large vibration stroke, so as to reduce various problems caused by the horizontal shift of the voice coil, will be the present invention Want to actively expose the place.
