音圈具有彈波功能的薄型揚聲器Thin loudspeaker with elastic coil function in voice coil

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 thin speaker 100 includes a frame (not shown), a magnetic loop device 102, a voice coil 103 and a diaphragm 104. The magnetic return device 102 is set in the frame and includes a base 1021, three magnets 1022, 1023, 1024 and three magnetically conductive metals 1025, 1026, 1027; the base 1021 is composed of magnetically conductive metal; the magnets 1022, 1023 and 1024 are arranged on the top of the base 1021 at intervals; the magnetically permeable metals 1025, 1026 and 1027 are respectively arranged on the top of the magnets 1022, 1023 and 1024. The voice coil 103 includes a tube 1031 and a wire 1032; the tube 1031 surrounds the space between the outside of the magnets 1022, 1023, 1024 and the inside of the magnets 1022, 1023, 1024 on both sides; the wire 1032 is wound around A coil 1033 is formed on the outer circumferential surface of the tube body 1031. The diaphragm 104 is disposed above the voice coil 103, and its bottom abuts the top of the tube 1031 of the voice coil 103.

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 thin speaker 100 is that when an electric current flows through the coil 1033 of the voice coil 103, an electromagnetic field is generated. This electromagnetic field and the fixed magnetic field of the magnetic return device 102 are at right angles to the phenomenon of attraction and repulsion, which makes the voice coil 103 The tube 1031 performs vertical reciprocating movement in the magnetic return device 102, and drives the diaphragm 104 to generate vertical reciprocating movement (ie, vibration), which causes the air to vibrate and emit audio to the human ear to achieve sound Restore the purpose of listening to people, and realize the conversion of electrical energy to acoustic energy.

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 thin loudspeaker 100 needs to be additionally connected with a wire (not shown), so as to withstand the thin loudspeaker 100 continuously sending signals into the wire 1032 under the condition of large vibration.

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 thin speaker 100 omits the elastic wave because of its thin design. Therefore, in the case of large amplitudes such as high volume and low frequency, it is extremely easy to cause the voice coil 103 to skew during the reciprocating process, and the distortion rate is extremely high. high.

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 thin speaker 100 has a large hanging edge compliance, and when the two ends of the wire 1032 are connected to the two terminals, they appear in a floating state. If it is additionally connected to the brocade thread, the brocade thread also appears to be suspended. Under long-term use, the wire 1032 or brocade wire is also easy to break. In addition, due to improper design or assembly or abnormal pulling of the lead wire 1032, the vibration of the voice coil 103 is unbalanced, which in turn causes distortion of the sound generated by the diaphragm 104. Moreover, the poor structural strength of the wire 1032 is also one of the factors that is easy to break, and the increase of the brocade wire will reduce the sound pressure. For the above reasons, the conventional thin speaker 100 cannot withstand large output power, is easily damaged, and produces poor sound quality.

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 wire 1032 of the general voice coil 103 is composed of a copper conductor 10321 covered with an insulating layer 10322, such as an enameled wire. As shown in FIG. 1, the cross section of the copper conductor 10321 is generally circular, and the cross section of the insulating layer 10322 is circular. Therefore, there is a point contact between the insulating layers 10322, so that there is a considerable gap between the wires 1032, so that the conductor area is small, resulting in more magnetic leakage and less magnetic flux, thus causing power loss of the thin speaker 100 More, and high and low bass will be distorted

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 voice coil 103, when the size of the conventional thin speaker 100 is too long, it is necessary to use multiple sets of magnetic loop devices 102 to increase the weight.

二端子(圖未示)穿過框體10的二端及該二支撐懸吊部312、313的穿孔314、315，然後分別連接於該二導電懸吊部322、323。電流從二端子通過該二導電懸吊部322、323導入第一線圈324和第二線圈325，並且產生電磁場，所述電磁場與磁迴裝置20的固定磁場呈直角方向而產生吸引排斥之現象。此時，支撐基板311會受到一個電動力，而受力方向則遵循左手定則。在受力發生後，支撐基板311開始在磁迴裝置20中進行上升下降的垂直往復運動，並且驅動振膜40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。Two terminals (not shown) pass through the two ends of the frame body 10 and the through holes 314 and 315 of the two support suspension parts 312 and 313, and then are connected to the two conductive suspension parts 322 and 323, respectively. Electric current is introduced into the first coil 324 and the second coil 325 from the two terminals through the two conductive suspension parts 322 and 323, and an electromagnetic field is generated. The electromagnetic field and the fixed magnetic field of the magnetic return device 20 are at right angles to the phenomenon of attraction and repulsion. At this time, the supporting substrate 311 will receive an electric force, and the direction of the force will follow the left-hand rule. After the force is generated, the supporting substrate 311 starts to move up and down vertically in the magnetic circuit device 20, and drives the diaphragm 40 to generate up and down vertical reciprocating movement (ie, vibration), which causes the air to vibrate and emit audio transmission. To the human ear, the purpose of sound restoration for human listening is achieved, and the conversion of electrical energy to acoustic energy is achieved.

重要的是，該二支撐懸吊部312、313可作為彈波，其可達到以下諸多功效：其一，可保持支撐基板311在磁迴裝置20中的正確位置；其二，保證支撐基板311在受力時，穩定沿著軸向進行上升下降的垂直往復運動；其三，和支撐基板311及振膜40共同決定本發明的諧振效率；其四，防止灰塵進入磁迴裝置20；其五，支撐該二導電懸吊部322、323。因為彈波音圈30同時擁有彈波和音圈的功能，所以本發明可維持既有的薄型化設計，又能夠在大音量、低頻等振幅較大的情況下，讓支撐基板311在往復運動的過程中保持上下移動，避免發生歪斜行為，降低失真率。What is important is that the two supporting suspension parts 312 and 313 can be used as elastic waves, which can achieve the following many effects: first, it can maintain the correct position of the supporting substrate 311 in the magnetic return device 20; second, ensure the supporting substrate 311 Under the force, the vertical reciprocating motion that rises and falls along the axial direction is stabilized; third, the resonance efficiency of the present invention is determined together with the supporting substrate 311 and the diaphragm 40; fourth, preventing dust from entering the magnetic return device 20; fifth To support the two conductive suspension parts 322, 323. Since the elastic wave voice coil 30 has the functions of both elastic wave and voice coil, the present invention can maintain the existing thin design, and can allow the supporting substrate 311 to reciprocate during the large volume, low frequency and other large amplitudes Keep moving up and down to avoid skew behavior and reduce the distortion rate.

再者，該二導電懸吊部322、323因可受到該二支撐懸吊部312、313的支撐，所以不容易碰觸到其他構件，防止產生異音。又，該二導電懸吊部322、323的結構強度佳，不易斷裂，只需確認導體321耐電流的參數，並且可應用於開口式框體10(音箱)。因此，彈波音圈30可大幅提升承受功率，維持振動系統(即，支撐基板311與導體321的組合加上振膜40)平衡，有效降低失真，進而提升聲音品質。Furthermore, since the two conductive suspension parts 322 and 323 can be supported by the two support suspension parts 312 and 313, it is not easy to touch other members to prevent the generation of abnormal sound. In addition, the two conductive suspension parts 322 and 323 have good structural strength and are not easily broken. It is only necessary to confirm the current resistance parameter of the conductor 321 and it can be applied to the open frame 10 (speaker box). Therefore, the elastic wave voice coil 30 can greatly increase the withstand power, maintain the balance of the vibration system (ie, the combination of the support substrate 311 and the conductor 321 plus the diaphragm 40), effectively reduce distortion, and thereby improve sound quality.

具體來說，在本實施例中，支撐件31為一軟性印刷電路板(Flexible Printed Circuit，FPC)，簡稱軟板，因此支撐基板311可供導體321以印刷方式在支撐基板311的二側上做線路布置旋繞形成第一線圈324與第二線圈325，作為訊號傳輸媒介。由於軟性印刷電路板具有可連續自動化生產、提高配線密度、重量輕、體積小、配線錯誤減少、可撓性及可彈性改變形狀等特性，相當適合用在本發明。在其他實施例中，亦可採用其他非軟性印刷電路板的材料作為支撐件31。本發明所採用的導體321的材料是「銅」，故其為銅導體321，但不限於此。導電懸吊部322、323所採用的材料也是「銅」並且厚度為0.0.5 mm，故其為銅箔，但不限於此。Specifically, in this embodiment, the supporting member 31 is a flexible printed circuit (FPC), referred to as a flexible board, so the supporting substrate 311 can provide conductors 321 on both sides of the supporting substrate 311 in a printed manner The circuit is arranged and wound to form a first coil 324 and a second coil 325 as a signal transmission medium. Because flexible printed circuit boards have the characteristics of continuous automated production, improved wiring density, light weight, small size, reduced wiring errors, flexibility and elastic shape change, they are quite suitable for use in the present invention. In other embodiments, other non-flexible printed circuit board materials may be used as the support 31.

The material used for the conductive suspension parts 322, 323 is also "copper" and the thickness is 0.0.5 mm, so it is copper foil, but it is not limited thereto.

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 support substrate 311 defines a through hole 3111. The through hole 3111 penetrates the two sides of the support substrate 311. The conductor 321 passes through the through hole 3111 from one side of the support substrate 311 and extends to the other side of the support substrate 311. One side; the conductor 321 from the through hole 3111 from inside to outside on the two sides of the support substrate 311 are formed by winding the first coil 324 and the second coil 325, thereby shortening the path of the conductor 321 extending on both sides of the support substrate 311. More specifically, as shown in FIGS. 11 and 13, the position of the through hole 3111 is close to one end of the support substrate 311 and below the center line of the length of the support substrate 311; the conductor 321 is first on one side of the support substrate 311 Extend downward, and then extend in the direction of the other end of the support substrate 311, then extend upward, and then extend in the direction of one end of the support substrate 311, and finally extend downward and flash through the through hole 3111 from the side of the through hole 3111 To form a complete circle of conductor 321; then, the next circle of conductor 321 bypasses the previous circle of conductor 321 in this way. The conductor 321 extends upward on the other side of the support substrate 311, then extends in the direction of the other end of the support substrate 311, then extends downward, then extends in the direction of one end of the support substrate 311, and finally extends upward and from One side of the through hole 3111 flashes through the opening of the through hole 3111 to form a complete turn of the conductor 321; then, the next turn of the conductor 321 bypasses the previous turn of the conductor 321 in this way. As shown in FIG. 10, through the above-mentioned winding method, the first coil 324 has a total of six turns of conductor 321, the second coil 325 has a total of seven turns of conductor 321, the first coil 324 has six turns of conductor 321 and the second coil 325 has six inner sides The position and winding path of the loop conductor 321 are almost the same. The conductor 321 only has a slightly different part just after passing through the through hole 3111 (one up, one down), and the second coil 325 has one more round of the conductor 321 on its outside .

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 conductor 321 is rectangular, and an insulating layer 326 is provided between the adjacent two turns of the conductor 321 in the first coil 324, and the adjacent in the second coil 325 An insulating layer 326 is provided between the two turns of the conductor 321.

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X軸代表聲壓級(SPL，sound pressure level)，單位為分貝(dB)；右側X軸代表阻抗(Resistence)，單位為歐姆(ohm)；Y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 X axis on the left represents sound pressure level (SPL) in decibels (dB); the X axis on the right represents impedance (Resistence) in ohms; the Y 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 loudspeaker suddenly dropped from about 78 decibels to about 68 decibels, a drop of about 10 decibels. 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X軸代表聲壓級(SPL，sound pressure level)，單位為分貝(dB)；右側X軸代表阻抗(Resistence)，單位為歐姆(ohm)；Y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 X axis on the left represents sound pressure level (SPL) in decibels (dB); the X axis on the right represents impedance (Resistence) in ohms; the Y 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分貝微幅上升至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 decibels 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 wave voice coil 30 of the present invention. This is the sound pressure level of the high frequency performance of the present invention. One of the reasons. The amplitude of the impedance increase of the conventional three-magnetic speaker at high frequency is between the present invention and the conventional dual-magnetic speaker. The inductance of the voice coil representing the conventional three-magnetic speaker is between the invention Between the elastic wave coil 30 and the voice coil of the conventional dual magnetic speaker, this is one of the reasons for the slight increase in the sound pressure level of the high frequency performance of the conventional triple magnetic speaker. The impedance of the conventional dual magnetic speaker at the high frequency is the largest, and the curve is the steepest, which represents the highest inductance of the voice coil of the conventional dual magnetic speaker, which is the highest of the conventional dual magnetic speaker. One of the reasons for the sudden drop in the sound pressure level of the frequency.

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.
