Description
本發明係關於一種音量平衡系統以及可攜式電子裝置,並且特別地,本發明係關於一種可動態調整兩揚聲器所播放之音量的音量平衡系統以及使用該音量平衡系統之可攜式電子裝置。The present invention relates to a volume balancing system and a portable electronic device, and in particular, to a volume balancing system that dynamically adjusts the volume played by two speakers and a portable electronic device using the volume balancing system.
由於近年來電子產業的蓬勃發展,以往只能固定於一處播放之功能,例如播放音樂或影片,現今皆可在非常小型的可攜式電子裝置上執行。舉例而言,各式手機、iPod、MP3播放器、多媒體播放器等,均具有播放影片及音樂、收聽廣播或播放電視節目之功能。Due to the booming electronics industry in recent years, functions that have previously been fixed in one place, such as playing music or movies, can now be performed on very small portable electronic devices. For example, various mobile phones, iPods, MP3 players, multimedia players, etc. all have the function of playing movies and music, listening to radio or playing TV programs.
與一般的音樂檔案及影片檔案不同,在KTV播放的伴唱帶檔案於錄製過程中已將左右聲道進行人聲分離,故當關閉播放伴唱帶檔案之其中一聲道,以及音量全部集中於另一聲道播放時,將使伴唱帶檔案可單獨播放音樂或人聲。然而於KTV中,由於其空間較大,故可設置多組喇叭,因此,當音量集中於一聲道時可利用數組喇叭來播放而於空間中產生聲道混合狀態,故對使用者而言並不會產生聽覺上的不適及差異。Different from general music files and video files, the vocal tape files played on KTV have separated the left and right channels during the recording process. Therefore, when one of the channels of the vocal tape file is closed, the volume is all concentrated in the other. When the channel is played, the vocal tape file will play music or vocals separately. However, in KTV, because of its large space, multiple sets of speakers can be set. Therefore, when the volume is concentrated on one channel, the array speaker can be used to play and the channel mixing state is generated in the space, so for the user. There is no auditory discomfort or difference.
目前的可攜式電子裝置因空間有限,考慮可攜帶性而通常無法裝設太多元件於其裝置內,因此,揚聲器(喇叭)最多僅能裝設兩組。請參閱圖一,圖一係繪示先前技術之可攜式電子裝置1的示意圖。如圖一所示,可攜式電子裝置1包含螢幕10以及設置於螢幕10兩邊之第一揚聲器12及第二揚聲器14。Due to limited space, current portable electronic devices generally cannot install too many components in their devices due to portability. Therefore, the speaker (horn) can only be installed in two groups at most. Please refer to FIG. 1 . FIG. 1 is a schematic diagram showing a portable electronic device 1 of the prior art. As shown in FIG. 1 , the portable electronic device 1 includes a screen 10 and a first speaker 12 and a second speaker 14 disposed on both sides of the screen 10 .
當上述可攜式電子裝置1播放伴唱帶檔案時,第一揚聲器12及第二揚聲器14的其中之一可播放人聲及其中之另一可播放音樂,且使用者可根據需要而自行調整第一揚聲器12及第二揚聲器14之音量大小。舉例而言,若第一揚聲器12播放人聲而第二揚聲器14播放音樂聲,同時使用者想讓原聲來帶領使用者時,可將第一揚聲器12所播放之人聲音量降到原有的百分之五十並且將第二揚聲器14所播放之音樂維持原音量。When the portable electronic device 1 plays the vocal tape file, one of the first speaker 12 and the second speaker 14 can play the vocal and another playable music, and the user can adjust the first one according to the need. The volume of the speaker 12 and the second speaker 14. For example, if the first speaker 12 plays the human voice and the second speaker 14 plays the music sound, and the user wants the original sound to lead the user, the amount of the human voice played by the first speaker 12 can be reduced to the original one. Fifty minutes and the music played by the second speaker 14 is maintained at the original volume.
然而,因可攜式電子裝置1較小,當左右聲道所發出之音量不平衡時,也會連帶影響使用者的手握穩定度。除此之外,由於可攜式電子裝置1僅能裝設兩組揚聲器,故當其中一組揚聲器所發出之音量降低時,使用者所聽到的聲音在聽覺上也較為不立體。再者,可攜式電子裝置1所能裝設的揚聲器較小,於輸出不平衡的同時也有可能造成音量過小的問題產生。However, since the portable electronic device 1 is small, when the volume of the left and right channels is unbalanced, it also affects the stability of the user's hand. In addition, since the portable electronic device 1 can only be equipped with two sets of speakers, when the volume emitted by one of the sets of speakers is lowered, the sound heard by the user is not stereoscopically stereoscopic. Moreover, the speaker that can be installed in the portable electronic device 1 is small, and the output may be unbalanced, and the problem that the volume is too small may also occur.
