Description
本發明係有關一種揚聲器,特別是一種音圈具有彈波功能的薄型揚聲器。The invention relates to a loudspeaker, especially a thin loudspeaker with a voice coil having an elastic wave function.
請參閱圖1,圖1是習知的薄型揚聲器的示意圖,習知的薄型揚聲器100包含一框體(圖未示)、一磁迴裝置102、一音圈103以及一振膜104。磁迴裝置102設於框體中,並且包含一底座1021、三塊磁鐵1022、1023、1024及三塊導磁金屬1025、1026、1027;底座1021由導磁金屬所構成;該等磁鐵1022、1023、1024間隔設置於底座1021的頂部;該等導磁金屬1025、1026、1027分別設於該等磁鐵1022、1023、1024的頂部。音圈103包含一管體1031及一導線1032;管體1031環繞設置於中間的磁鐵1022、1023、1024的外側與兩旁的磁鐵1022、1023、1024的內側之間的空間中;導線1032旋繞在管體1031的外周面而形成一線圈1033。振膜104設於音圈103的上方,並且其底部抵靠於音圈103的管體1031的頂部。Please refer to FIG. 1. FIG. 1 is a schematic diagram of a conventional thin speaker. The conventional
習知的薄型揚聲器100的工作原理是當電流流過音圈103的線圈1033時產生了電磁場,這個電磁場與磁迴裝置102的固定磁場呈直角方向而產生吸引排斥之現象,這使得音圈103的管體1031在磁迴裝置102中進行上升下降的垂直往復運動,並且驅動振膜104產生上升下降的垂直往復運動(即,振動) ,從而使空氣振動而發出音頻傳送到人耳,達到聲音還原供人聆聽的目的,實現了電能到聲能的轉換。The working principle of the conventional
大功率的薄型揚聲器100則需要另外連接錦絲線(圖未示),藉以承受薄型揚聲器100在大幅度振動的情況下,持續將訊號送入導線1032。The high-power
然而,習知的薄型揚聲器100因為薄型化設計而省略彈波,因此在大音量、低頻等振幅較大的情況下,極為容易造成音圈103在往復運動的過程中發生歪斜行為,失真率極高。However, the conventional
再者,習知的薄型揚聲器100的懸邊順性大,導線1032的二端與二端子連接後,呈現懸空狀態。若其另外連接錦絲線,則錦絲線也同樣呈現懸空狀態。長期使用下,導線1032或錦絲線亦容易斷裂。另外,導線1032亦容易因設計或組裝不當或異常拉扯,造成音圈103的振動不平衡,進而造成振膜104所產生的聲音失真。更且,導線1032的結構強度較差也是容易斷裂的因素之一,而增加錦絲線以後又會降低聲壓。基於上述理由,習知的薄型揚聲器100無法承受大輸出功率,容易毀損,並且產生低劣的聲音品質。In addition, the conventional
此外,一般音圈103的導線1032由包覆有絕緣層10322的銅導體10321所構成,例如漆包線。如圖1所示,銅導體10321的截面通常為圓形,絕緣層10322的截面為圓環形。因此,絕緣層10322之間為點接觸,使得導線1032之間存在有相當大的間隙,從而導體面積較小,導致較多的磁漏而有較小的磁通量,因而導致薄型揚聲器100的功率漏失多,並且高低音會失真。In addition, the
又,受限於音圈103的形狀,當習知的薄型揚聲器100的尺寸過長時,需要使用多組磁迴裝置102,增加重量。Moreover, due to the shape of the

如圖10至圖13所示,支撐基板311開設一貫孔3111,貫孔3111貫穿支撐基板311的二側,導體321從支撐基板311的一側穿過貫孔3111而延伸至支撐基板311的另一側;導體321從貫孔3111由內而外在支撐基板311的二側分別旋繞形成第一線圈324與第二線圈325,藉以縮短導體321延伸於支撐基板311的二側的路徑。更明確地說,如圖11及圖13所示,貫孔3111的位置靠近支撐基板311的一端並且位在支撐基板311的長度方向的中線下方;導體321在支撐基板311的其中一側先往下延伸,再往支撐基板311的另一端的方向延伸,接著往上延伸,再往支撐基板311的一端的方向延伸,最後再往下延伸並且從貫孔3111的一側閃過貫孔3111的開口,以形成完整的一圈導體321;接著,下一圈導體321以此方式繞過前一圈的導體321。導體321在支撐基板311的另一側先往上延伸,再往支撐基板311的另一端的方向延伸,接著往下延伸,再往支撐基板311的一端的方向延伸,最後再往上延伸並且從貫孔3111的一側閃過貫孔3111的開口,以形成完整的一圈導體321;接著,下一圈導體321以此方式繞過前一圈的導體321。如圖10所示,透過上述旋繞方式,第一線圈324總共有六圈導體321,第二線圈325總共有七圈導體321,第一線圈324的六圈導體321和第二線圈325的內側六圈導體321的位置及旋繞路徑幾乎相同,導體321只有穿出貫孔3111後剛開始的部分略有不同(一個往上,一個往下),第二線圈325多了一圈導體321在其外側。As shown in FIGS. 10 to 13, the
重要的是,如圖5及圖10所示,導體321的截面為矩形,第一線圈324中的相鄰的二圈導體321之間設有一層絕緣層326,第二線圈325中的相鄰的二圈導體321之間設有一層絕緣層326。藉此,每一圈導體321藉由絕緣層326以面接觸無間隙的設計,具有較大的導體321面積而有更高的磁通量,有效達到低磁漏的高效率音效輸出,並提升本發明的最大效能等優勢。Importantly, as shown in FIGS. 5 and 10, the cross section of the
值得一提的是,如圖7及圖11所示,該二導電懸吊部322、323與導體321的二端的銜接處分別彎折成二定位板327,該二定位板327分別抵靠於支撐基板311的二側。因為該二定位板327平行於導體321,所以導體321的二端和該二定位板327的連接處無須彎折,防止導體321的二端和該二定位板327的連接處發生斷裂的問題。It is worth mentioning that, as shown in FIGS. 7 and 11, the junctions of the two

However, the shapes of the two
請參閱圖14,圖14為本發明和習知技術的頻率反應曲線特性比較圖。左側Y軸代表聲壓級(SPL,sound pressure level),單位為分貝(dB);右側Y軸代表阻抗(Resistence),單位為歐姆(ohm);X軸代表頻率,單位為赫茲(Hz)。以下將配合圖14說明,在同樣的尺寸條件下,本發明和習知的雙磁迴揚聲器與習知的三磁迴揚聲器的頻率反應曲線(Frequency Response Curve)特性的差異。 Please refer to FIG. 14, which is a comparison diagram of the frequency response curve characteristics of the present invention and the conventional technology. The left Y-axis represents sound pressure level (SPL) in decibels (dB); the right Y-axis represents impedance (Resistence) in ohms; the X-axis represents frequency in Hertz (Hz). In the following, with reference to FIG. 14, under the same size conditions, the difference between the frequency response curve (Frequency Response Curve) characteristics of the dual magnetic loop speaker of the present invention and the conventional one and the conventional three magnetic loop speaker.
首先,比對本發明和習知的雙磁迴揚聲器與習知的三磁迴揚聲器的高頻(一萬赫茲~二萬赫茲)表現。習知的雙磁迴揚聲器從約78分貝驟降至約68分貝,下降幅度約10分貝。習知的三磁迴揚聲器從約82分貝微幅上升至86分貝,上升幅度約4分貝。本發明從約82分貝驟升至約95分貝,上升幅度約13分貝。 First, compare the high frequency (10,000 Hz to 20,000 Hz) performance of the dual magnetic loop speaker of the invention and the conventional three magnetic loop speaker. The conventional dual-magnetic-back speaker dropped from about 78 dB to about 68 dB, a drop of about 10 dB. The conventional three-magneto loudspeaker rose slightly from about 82 decibels to 86 decibels, an increase of about 4 decibels. The invention jumps from about 82 decibels to about 95 decibels, with an increase of about 13 decibels.
依據上述比對結果,本發明的高頻表現的聲壓級上升幅度最大,足足超過習知的三磁迴揚聲器的高頻表現的聲壓級上升的幅度至少9分貝,因此本發明的高頻表現為三者中最優秀者。習知的三磁迴揚聲器的高頻表現的聲壓級上升幅度介於本發明與習知的雙磁迴揚聲器之間,因此習知的三磁迴揚聲器的高頻表現為三者中的次佳者。習知的雙磁迴揚聲器的高頻表現的聲壓級是下降的,故習知的雙磁迴揚聲器的高頻表現為三者中最差勁者。 According to the above comparison results, the sound pressure level of the high-frequency performance of the present invention has the largest increase, which exceeds the sound pressure level of the conventional three-magnetic-back speaker by at least 9 decibels. Frequency performance is the best of the three. The increase in the sound pressure level of the high frequency performance of the conventional three-magnetic speaker is between the invention and the conventional dual-magnetic speaker, so the high-frequency performance of the conventional three-magnetic speaker is the second of the three The best. The sound pressure level of the high frequency performance of the conventional dual magnetic speaker is decreased, so the high frequency performance of the conventional dual magnetic speaker is the worst among the three.
因此,相較於習知的雙磁迴揚聲器和三磁迴揚聲器,本發明的高頻具有極佳的延展性,低頻亦維持在一定的水準,音壓效率為三者最高,可作為全音域揚聲器,亦可單獨作為高頻揚聲器。 Therefore, compared with the conventional dual magnetic speaker and triple magnetic speaker, the high frequency of the present invention has excellent ductility, the low frequency is also maintained at a certain level, the sound pressure efficiency is the highest of the three, and can be used as the full range The speaker can also be used as a high-frequency speaker alone.
請參閱圖15,圖15為本發明和習知技術的阻抗曲線特性比較圖。左側Y軸代表聲壓級(SPL,sound pressure level),單位為分貝(dB);右側Y軸代表阻抗(Resistence),單位為歐姆(ohm);X軸代表頻率,單位為赫茲(Hz)。以下將配合圖15說明,在同樣的尺寸條件下,本發明和習知的雙磁迴揚聲器與習知的三磁迴揚聲器的阻抗曲線(Impedance Curve)特性的差異。 Please refer to FIG. 15, which is a comparison diagram of the impedance curve characteristics of the present invention and the conventional technology. The left Y-axis represents sound pressure level (SPL) in decibels (dB); the right Y-axis represents impedance (Resistence) in ohms; the X-axis represents frequency in Hertz (Hz). The following will describe with reference to FIG. 15 that under the same size conditions, the difference between the impedance curve characteristics of the dual magnetic speakers of the present invention and the conventional three magnetic speakers and the conventional three magnetic speakers.
首先,比對本發明和習知的雙磁迴揚聲器與習知的三磁迴揚聲器在高頻(一萬赫茲~二萬赫茲)時的阻抗表現。習知的雙磁迴揚聲器的阻抗值從約4.7歐姆驟升至約6.5歐姆,上升幅度約1.8歐姆。習知的三磁迴揚聲器的阻抗值從約4.5歐姆微幅上升至約5.3歐姆,上升幅度約0.8歐姆。本發明的阻抗值從約5歐姆微幅上升至5.2歐姆,上升幅度約0.2歐姆。 First, compare the impedance performance at high frequencies (10,000 Hz to 20,000 Hz) of the dual magnetic loop speaker of the invention and the conventional three magnetic loop speaker. The impedance value of the conventional dual-magnetic-back loudspeaker suddenly rises from about 4.7 ohms to about 6.5 ohms, with an increase of about 1.8 ohms. The impedance value of the conventional three-magnetic-back loudspeaker slightly increased from about 4.5 ohms to about 5.3 ohms, with an increase of about 0.8 ohms. The impedance value of the present invention rises slightly from about 5 ohms to 5.2 ohms, and the rising range is about 0.2 ohms.
音圈的阻抗上升幅度代表其電感抗程度。依據上述比對結果,本發明在高頻表現時的阻抗上升幅度最小,曲線最為平坦,代表本發明的彈波音圈30的電感抗程度最低,此為本發明的高頻表現的聲壓級驟升的原因之一。習知的三磁迴揚聲器在高頻表現時的阻抗上升幅度介於本發明與習知的雙磁迴揚聲器之間,代表習知的三磁迴揚聲器的音圈的電感抗程度介於本發明的彈波音圈30與習知的雙磁迴揚聲器的音圈之間,此為習知的三磁迴揚聲器的高頻表現的聲壓級微幅上升的原因之一。習知的雙磁迴揚聲器在高頻表現時的阻抗上升幅度最大,曲線最為陡峭,代表習知的雙磁迴揚聲器的音圈的電感抗程度最高,此為習知的雙磁迴揚聲器的高頻表現的聲壓級驟降的原因之一。The increase in the impedance of the voice coil represents the degree of inductance. According to the above comparison results, the impedance increase amplitude of the present invention at high frequency performance is the smallest, and the curve is the flattest, which represents the lowest inductance of the elastic
其次,比對本發明和習知的雙磁迴揚聲器與習知的三磁迴揚聲器在低頻(一百赫茲~一千赫茲)時的阻抗表現,峰值頻率位置愈低,表示低頻延伸愈佳。本發明的峰值介於中間,後續可以藉由調整本發明的懸吊系統(即,該二支撐懸吊部312、313、該二導電懸吊部322、323、該二第一夾持懸吊部332、333與該二第二夾持懸吊部342、343的組合和懸邊)的結構,以達到需求的峰值頻率位置,並與承受功率及失真取得平衡點。Secondly, comparing the impedance performance at low frequencies (100 Hz to 1000 Hz) of the dual magnetic loop speakers of the present invention and the conventional three magnetic loop speakers, the lower the peak frequency position, the better the low frequency extension. The peak value of the present invention is in the middle, and the suspension system of the present invention (ie, the two supporting
