The frame 112' is different from the aforementioned frame 112 in the relationship between the length direction of the side through hole and the radial direction of the frame. In this embodiment, the length direction of the side through hole is substantially perpendicular to the radial direction R of the circular frame 112', for example, the length direction D2 of the side through hole 112c' is substantially perpendicular to the radial direction R of the circular frame 112'. The length direction of the side through hole 112d' is also substantially perpendicular to the radial direction R of the circular frame 112'. Similar to the design of the frame 112, the total area of the side through holes 112c' of the frame 112' is smaller than the total area of the side through holes 112d'.
請參照第6圖,其繪示本發明之不同實施例的揚聲器總諧波失真的性能比較圖。在本圖中所比較的揚聲器實施例,分別包含態樣A、B、C三種框架,其圖式分別繪示於圖中。態樣A之框架的高音音室內側通孔(4x2個通孔)總面積小於低音音室內側通孔(6x2個通孔)總面積。態樣B之框架的高音音室內側通孔(3x2個較小通孔)總面積小於低音音室內側通孔(3x2個較大通孔)總面積。態樣C之框架的高音音室內側通孔總面積等於低音音室內側通孔總面積。參照態樣A、B、C所對應的揚聲器總諧波失真(Total Harmonic Distortion,THD)比率曲線可知,在頻率30Hz到200Hz之間,就揚聲器輸出音效的總諧波失真比率而言,態樣A之揚聲器小於態樣B之揚聲器,且態樣B之揚聲器小於態樣C之揚聲器。具體而言,在頻率100Hz時,態樣A的總諧波失真比率為4.17%、態樣B的總諧波失真比率為5.60%、態樣C的總諧波失真比率為6.53%。在頻 率200Hz時,態樣A的總諧波失真比率為0.66%、態樣B的總諧波失真比率為0.87%、態樣C的總諧波失真比率為1.43%。總諧波失真比率越低表示揚聲器能更真實的輸出音效。此外,態樣A、B之框架上的長條形側通孔亦有助於減低總諧波失真比率。 Please refer to Fig. 6, which shows a comparison diagram of the total harmonic distortion performance of the speakers of different embodiments of the present invention. The loudspeaker embodiments compared in this figure respectively include three types of frames A, B, and C, and the diagrams are respectively shown in the figure. The total area of the through holes (4x2 through holes) in the tweeter chamber of the frame of aspect A is smaller than the total area of the through holes (6x2 through holes) in the bass sound chamber. The total area of the through holes in the tweeter chamber (3x2 smaller through holes) of the frame of aspect B is smaller than the total area of the through holes in the bass sound chamber (3x2 larger through holes). The total area of the through holes in the tweeter chamber of the frame of aspect C is equal to the total area of the through holes in the bass chamber. Referring to the total harmonic distortion (THD) ratio curve of the speaker corresponding to the patterns A, B, and C, it can be seen that between the frequency of 30Hz and 200Hz, in terms of the total harmonic distortion ratio of the speaker output sound effect, the pattern The speaker of A is smaller than the speaker of aspect B, and the speaker of aspect B is smaller than the speaker of aspect C. Specifically, at a frequency of 100 Hz, the total harmonic distortion ratio of aspect A is 4.17%, the total harmonic distortion ratio of aspect B is 5.60%, and the total harmonic distortion ratio of aspect C is 6.53%. On frequency When the frequency is 200 Hz, the total harmonic distortion ratio of aspect A is 0.66%, the total harmonic distortion ratio of aspect B is 0.87%, and the total harmonic distortion ratio of aspect C is 1.43%. The lower the total harmonic distortion ratio means that the speaker can output more realistic sound effects. In addition, the elongated side through holes on the frames of the aspects A and B also help to reduce the total harmonic distortion ratio.
綜上所述,本發明之揚聲器結構,藉其音域隔牆以區隔出高音音室以及低音音室,而使振動膜產生的高、低音具有各自獨立的音室與環繞通道以避免高、低音混合,另配合框架之側通孔的形狀設計以及於高、低音音室的總面積差異,進而減低總諧波失真比率,提升高、低音輸出的音質。 In summary, the loudspeaker structure of the present invention separates the tweeter room and the bass room by the sound range partition wall, so that the high and low frequencies generated by the diaphragm have separate sound rooms and surround channels to avoid high and low frequencies. The bass mixing is matched with the shape design of the side through holes of the frame and the difference in the total area of the high and low sound chambers, thereby reducing the total harmonic distortion ratio and improving the sound quality of the high and low output.
