具有單鍵聲音補償功能的聲音輸入裝置及聲音補償方法Sound input device with single-key sound compensation function and sound compensation method

一般來說在演唱時，特別是最後一句的最後一個字拉長尾音的時候，常常會發生因演唱者的中氣不足而無法完美延續最後音調及強度的狀況。雖然此問題可以藉由事後的程式化修補來調整音調高低或是聲音強度而解決，但仍然無法即時應付現場以及直播的演唱或演講的情況。Generally speaking, when singing, especially when the last word of the last sentence has a long tail, it often happens that the singer's lack of energy can't continue the last tone and intensity perfectly. Although this problem can be solved by adjusting the pitch or sound intensity through the stylized repair afterwards, it still can't cope with the situation of live or live singing or speech in real time.

為了要解決這個問題，過去針對麥克風進行改良的方式都是傾向於直接播放預先所錄製的版本、或是原版的聲音。但這種方式會讓現場的演唱嚴重失真，且必須要使用大量的空間來儲存欲播放的音軌，實施上相當麻煩。In order to solve this problem, the way to improve the microphone in the past is to directly play the pre-recorded version or the original sound. However, this method will seriously distort the live singing, and must use a lot of space to store the audio track to be played, which is quite troublesome to implement.

The key-pressed state here refers to the state where the key is pressed by the user, and the normal state of the key is the state where the key is generally not pressed. Of course, the switching of the two states can be set by the user in other ways, for example: Up or down, or directly covering the button with an object (such as a finger), the present invention does not limit this. In addition, more precisely, the predetermined period of time can be set by the user in advance, for example, a four-beat or eight-beat rhythm. It is worth noting that the predetermined time should not be too long, at least it must be a time period that can be played repeatedly without large fluctuations. In addition, the average value of the part of the temporarily stored digital signal includes at least the average value of the signal frequency and the average value of the signal strength.

圖3為本發明之聲音補償方法的流程圖，以本發明之具有單鍵聲音補償功能的聲音輸入裝置(如圖1中的麥克風)來達成。圖4為本發明之聲音補償方法的功效示意圖。同時參閱圖1、圖2、圖3及圖4，本發明之聲音補償方法包括下列步驟。FIG. 3 is a flowchart of the sound compensation method of the present invention.The sound input device (such as the microphone in FIG. 1) of the key sound compensation function is achieved. 4 is a schematic diagram of the efficacy of the sound compensation method of the present invention. Referring to FIGS. 1, 2, 3, and 4 at the same time, the sound compensation method of the present invention includes the following steps.

步驟S1：藉由聲音輸入部2收集聲音，聲音為類比訊號，包括人聲及環境音。Step S1: Collect the sound through thesound input unit 2, the sound is an analog signal, including human voice and ambient sound.

步驟S2：藉由訊號處理模組11中的類比數位轉換器111將類比訊號轉換為數位訊號。Step S2: Convert the analog signal into a digital signal by the analog-to-digital converter 111 in thesignal processing module 11.

步驟S3：藉由電路模組12的緩衝單元121接收來自訊號處理模組11的類比數位轉換器111的數位訊號，並將數位訊號暫存於緩衝單元121中。人聲擷取單元123將人聲訊號自數位訊號中分離出來。抗噪單元124降低人聲訊號之外(即：環境音)的訊號強度。自動增益單元125將人聲訊號的訊號強度放大，並將經過抗噪及人聲增益後的數位訊號暫存於緩衝單元121中。Step S3: Thebuffer unit 121 of thecircuit module 12 receives the digital signal from the analog-to-digital converter 111 of thesignal processing module 11 and temporarily stores the digital signal in thebuffer unit 121. Thevocal extraction unit 123 separates the vocal signal from the digital signal. Theanti-noise unit 124 reduces the signal strength outside the vocal signal (ie, ambient sound). Theautomatic gain unit 125 amplifies the signal strength of the vocal signal, and temporarily stores the digital signal after the anti-noise and vocal gain in thebuffer unit 121.

步驟S4：回應於按鍵100的按壓狀態而產生補償狀態。值得注意的是，電路模組12的運算單元122也可以根據補償狀態的產生，方開啟人聲擷取單元123、抗噪單元124以及自動增益單元125的功能，以達到省電的功效。Step S4: A compensation state is generated in response to the pressed state of thebutton 100. It is worth noting that theoperation unit 122 of thecircuit module 12 can also generate the functions of thevocal extraction unit 123, theanti-noise unit 124, and theautomatic gain unit 125 according to the generation of the compensation state, so as to achieve the power saving effect.

步驟S5：回應於產生補償狀態，藉由電路模組12的運算單元122，擷取暫存數位訊號的部份，並計算出暫存數位訊號的部份的平均值以獲得數位平均值訊號。參閱圖4，於按鍵100被按壓的當下(P1時間點)，可以往前截取一段預定時間(例如4拍)，當作暫存數位訊號的部分，藉由運算單元122計算出這部分的平均值以獲得數位平均值訊號。Step S5: In response to generating the compensation state, thearithmetic unit 122 of thecircuit module 12 retrieves the portion of the temporarily stored digital signal, and calculates the average value of the temporarily stored digital signal to obtain the digital average signal. Referring to FIG. 4, at the moment when thebutton 100 is pressed (time P1), a predetermined period of time (for example, 4 beats) can be intercepted forward as a part of the temporarily stored digital signal, and the average of this part is calculated by thearithmetic unit 122 Value to obtain a digital average signal.

步驟S6：藉由訊號處理模組11的數位類比轉換器112將數位平均值訊號轉換為類比平均值訊號。Step S6: The digital average signal is converted into an analog average signal by the digital-to-analog converter 112 of thesignal processing module 11.

步驟S7：藉由揚聲器3將接收自訊號處理模組11的數位類比轉換器112的類比平均值訊號傳送出殼體2，如圖4中的虛線所示。必須注意的是，按壓狀態中的類比平均值訊號傳送會至少部分取代原先的數位訊號，於本實施例中為完全取代。另外，由於是持續播送平均值訊號，因此虛線部分的音調一致，不會被使用者(演唱者)的音調下降而影響。Step S7: The analog average signal of the digital-to-analog converter 112 received from thesignal processing module 11 is transmitted out of thehousing 2 through the speaker 3, as shown by the dotted line in FIG. It must be noted that the analog average signal transmission in the pressed state will be at least partiallySubstituting for the original digital signal is a complete replacement in this embodiment. In addition, since the average signal is continuously broadcast, the tone of the dotted line is consistent, and it will not be affected by the drop of the tone of the user (singer).

步驟S8：回應於所述按鍵100的常規狀態而產生停止補償狀態。電路模組12的運算單元122可以根據停止補償狀態的產生，而關閉人聲擷取單元123、抗噪單元124以及自動增益單元125的功能，以達到省電的功效。Step S8: In response to the normal state of thebutton 100, a stop compensation state is generated. Thecomputing unit 122 of thecircuit module 12 can disable the functions of thevocal capture unit 123, theanti-noise unit 124, and theautomatic gain unit 125 according to the generation of the stop compensation state to achieve the power saving effect.

步驟S9：回應於產生停止補償狀態，而停止傳送類比平均值訊號。參閱圖4，從按鍵100被按壓到停止按壓的這段時間週期(即P1時間點至P2時間點週期)，本發明之聲音輸入裝置係播放數位平均值訊號(虛線)而非使用者原先的數位訊號(實線)。Step S9: In response to the generation of the stop compensation state, the transmission of the analog average signal is stopped. Referring to FIG. 4, during the period from when thebutton 100 is pressed to when it is stopped (that is, from the period P1 to the period P2), the sound input device of the present invention plays a digital average signal (dashed line) instead of the user’s original Digital signal (solid line).

根據以上實施例，本發明揭露書所揭示之具有單鍵聲音補償功能的聲音輸入裝置僅需使用者單鍵操作控制(按壓及停止按壓)，便可以在自覺快要沒氣的情況下，輕易維持較為標準的音調及聲音強度。如此一來，對於演唱者而言，能夠透過簡單直接的方式來改善演唱時的表現。According to the above embodiments, the sound input device with the one-key sound compensation function disclosed in the disclosure of the present invention only needs the user's one-key operation control (pressing and stopping pressing), and can easily maintain it without consciously running out of gas More standard pitch and sound intensity. In this way, for the singer, the performance during singing can be improved in a simple and direct way.

綜上所述，藉由本發明之具有單鍵聲音補償功能的聲音輸入裝置，無論在生產上、或是使用上皆較傳統方式更方便、更有效，且不用耗費過多的成本資源。In summary, the sound input device with single-key sound compensation function of the present invention is more convenient and more effective than traditional methods in production or use, and does not consume excessive cost resources.

惟以上所述僅為本發明之較佳可行實施例，非因此即侷限本發明之專利範圍，故舉凡運用本發明說明書及圖示內容所為之等效結構變化，均同理包含於本發明之範圍內，合予陳明。However, the above is only a preferred and feasible embodiment of the present invention, and therefore does not limit the scope of the patent of the present invention. Therefore, any equivalent structural changes caused by using the description and illustration content of the present invention are equally included in the present invention.
