如圖5所示，具有虛擬多聲道音效的聲音播放設備4更包含無線電子裝置44與電路模組45。無線電子裝置44用以無線傳送第二音訊(聲音標準訊號)至發聲裝置43；電路模組45包含數位訊號處理器41與聲音編解碼器42。其中，於此實施例，發聲裝置43包含第一揚聲器431與第二揚聲器432(但揚聲器之數量不限定於此)，以分別作為具有虛擬多聲道音效的聲音播放設備4之左聲道與右聲道。As shown in FIG. 5, the sound playback device 4 having virtual multi-channel sound effects further includes a wireless electronic device 44 and a circuit module 45. The wireless electronic device 44 is configured to wirelessly transmit a second audio (sound standard signal) to the sounding device 43. The circuit module 45 includes a digital signal processor 41 and a sound codec 42. In this embodiment, the sounding device 43 includes the first speaker 431 and the second speaker 432 (but the number of the speakers is not limited thereto) to respectively serve as the left channel of the sound playing device 4 having the virtual multi-channel sound effect. Right channel.
具體而言，電子裝置40將第一音訊(原始音訊)傳送至電路模組45，以供數位訊號處理器41以虛擬多聲道音場處理程序對第一音訊進行訊號處理，而藉此產生虛擬多聲道音場訊號。例如，虛擬多聲道音場處理程序可為數位訊號處理器41利用虛擬環繞演算法，去改變第一音訊的相位與音壓(例如，音量)而實現。於此所述之虛擬環繞演算法可為虛擬多聲道之演算法(例如：虛擬五聲道(5.1)、虛擬七聲道(7.1)或虛擬九聲道(9.1)等之演算法，但不限定於此)，數位訊號處理器41利用此虛擬多聲道之演算法對第一音訊進行訊號處理，以產生虛擬多聲道音場訊號。Specifically, the electronic device 40 transmits the first audio (original audio) to the circuit module 45, so that the digital signal processor 41 performs signal processing on the first audio by using a virtual multi-channel sound field processing program, thereby generating Virtual multi-channel sound field signal. For example, the virtual multi-channel sound field processing program can be implemented by the digital signal processor 41 using a virtual surround algorithm to change the phase and sound pressure (eg, volume) of the first audio. The virtual surround algorithm described herein can be a virtual multi-channel algorithm (eg, virtual five-channel (5.1), virtual seven-channel (7.1), or virtual nine-channel (9.1) algorithms, but Not limited to this, the digital signal processor 41 uses the virtual multi-channel algorithm to perform signal processing on the first audio to generate a virtual multi-channel sound field signal.
聲音編解碼器42接收此虛擬多聲道音場訊號以產生第二音訊。所述聲音編解碼器42可將音訊整合成聲音標準訊號。於此，聲音編解碼器42將虛擬多聲道音場訊號整合並產生第二音訊(聲音標準訊號)。此部分為熟悉該領域之技術人士所能理解之範疇，於此不另贅述。The sound codec 42 receives the virtual multi-channel sound field signal to produce a second sound. The sound codec 42 can integrate the audio into a sound standard signal. Here, the sound codec 42 integrates the virtual multi-channel sound field signal and generates a second audio (sound standard signal). This section is intended to be understood by those skilled in the art and will not be further described herein.
之後，無線電子裝置44透過無線技術(例如：2.4G或5.8G)的傳輸方式將此第二音訊傳送至發聲裝置43。發聲裝置43之第一揚聲器431與第二揚聲器432(例如：無線揚聲器)用以接收第二音訊，並依據此第二音訊播放出虛擬多聲道聲音(例如：虛擬五聲道(5.1)、虛擬七聲道(7.1)或虛擬九聲道(9.1)之聲音，但不限定於此)。Thereafter, the wireless electronic device 44 transmits the second audio to the sounding device 43 via a wireless technology (eg, 2.4G or 5.8G) transmission. The first speaker 431 and the second speaker 432 (for example, a wireless speaker) of the sounding device 43 are configured to receive the second audio, and play the virtual multi-channel sound according to the second audio (eg, virtual five-channel (5.1), Virtual seven-channel (7.1) or virtual nine-channel (9.1) sound, but not limited to this).
由上述可知，本新型實施例所述之具有虛擬多聲道音效的聲音播放設備，具有下列之特點：利用數位訊號處理器的虛擬多聲道音場處理程序，對第一音訊(原始音訊)直接進行聲音訊號處理，以產生虛擬多聲道音場訊號，最後透過發聲裝置(例如，第一揚聲器(左聲道)與第二揚聲器(右聲道))播放出虛擬多聲道聲音，令使用者能夠享受到豐富的立體聆聽感；並且，由於數位訊號處理器本身具有虛擬多聲道音場處理的能力，因此在不必改變發聲裝置之實體結構的基礎下，即可令發聲裝置播放出虛擬多聲道聲音，如此可降低聲音播放設備的產品設計成本。It can be seen from the above that the sound playing device with virtual multi-channel sound effect described in the new embodiment has the following features: a virtual multi-channel sound field processing program using a digital signal processor, and the first audio (original audio) Directly performing sound signal processing to generate a virtual multi-channel sound field signal, and finally playing a virtual multi-channel sound through a sounding device (for example, a first speaker (left channel) and a second speaker (right channel)) The user can enjoy rich stereoscopic listening feeling; and, since the digital signal processor itself has the capability of virtual multi-channel sound field processing, the sounding device can be played out without changing the physical structure of the sounding device. Virtual multi-channel sound, which reduces the product design cost of sound playback devices.
