Description

具有彈波之矩形微型揚聲器Rectangular microspeaker with sprung waves

本新型有關一種具有彈波之矩形微型揚聲器，尤指一種增加貼合面積提升彈波對音圈控制力之設計者。The present invention relates to a rectangular micro-speaker with elastic waves, especially a design which increases the bonding area and improves the control force of elastic waves on the voice coil.

按，由於現今消費性電子產品在追求薄型化趨勢下，同時又要求具有大音量輸出，因此導致其所內建的矩形微型揚聲器，需承受更高的電功率，以便產生更大的音量輸出；然而，外部輸入的功率愈高，揚聲器振膜的振幅勢必會更大，才能產生更大的聲音輸出，但振膜是由音圈所推動；因此，必須先確保音圈在大功率下，能穩定地在同一軸線上，進行往復式的大位移量振動，而不會產生偏移，撞擊到揚聲器其他元件，導致揚聲器失效與失真。Press, because today's consumer electronics products are pursuing the trend of thinning, and at the same time require a large volume output, so the built-in rectangular micro-speaker needs to withstand higher electric power in order to produce a larger volume output; however , the higher the external input power, the greater the vibration amplitude of the speaker diaphragm, in order to produce greater sound output, but the diaphragm is driven by the voice coil; therefore, it must be ensured that the voice coil can be stable under high power. The ground is on the same axis for reciprocating large-displacement vibration without offsetting and impacting other components of the speaker, resulting in failure and distortion of the speaker.

次按，為了確保音圈能穩定地沿著同一軸向進行往復式振動而不偏移，習知的作法是在音圈的底部設置彈波(damper)，當音圈作動的能量過大產生偏移時，能緩和偏移的振動量，發揮阻尼效益，使音圈得以維持在同一軸線上振動；然而，如圖1、圖7所示，矩形微型揚聲器因為超薄的設計，導致習知的作法，通常只能將一片狀彈波10a對稱設於矩形音圈20兩側的音圈短邊22底面，該片狀彈波10a具有一支架結合部11、一音圈結合部12a與一連接部13；不過，由於片狀彈波10a的音圈結合部12a為平面型態，致使音圈結合部12a與矩形音圈20底部僅為單一平面的小面積接合，因此當矩形音圈20在大功率下作動時，片狀彈波10a無法完全發揮對矩形音圈20的控制力，導致阻尼效果不佳。Press again, in order to ensure that the voice coil can stably vibrate reciprocatingly along the same axis without deflection, the known practice is to set a damper at the bottom of the voice coil. When shifting, it can ease the vibration of the offset, exert the damping effect, and keep the voice coil vibrating on the same axis; however, as shown in Figure 1 and Figure 7, the rectangular micro-speaker has a conventional Generally, the sheet-shaped elastic wave 10a can only be symmetrically arranged on the bottom surface of the short side 22 of the voice coil on both sides of the rectangular voice coil 20. The sheet-shaped elastic wave 10a has a support joint 11, a voice coil joint 12a and a Connecting part 13; however, since the voice coil joint part 12a of the plate elastic wave 10a is a planar shape, the voice coil joint part 12a and the bottom of the rectangular voice coil 20 are only joined by a small area of a single plane, so when the rectangular voice coil 20 When actuating under high power, the sheet elastic wave 10a cannot fully exert its control force on the rectangular voice coil 20, resulting in poor damping effect.

本新型之主要目的，欲解決先前技術彈波對音圈控制力不佳之問題，而具有提升彈波對音圈控制力之功效。The main purpose of this new model is to solve the problem of poor control of the elastic wave on the voice coil in the prior art, and to improve the control ability of the elastic wave on the voice coil.
