現在將詳細參考本發明的示範性實施例，並在附圖中說明所述的示範性實施例的實例。另外，在圖式及實施方式中所使用的相同或類似標號的元件/構件是用來代表相同或類似部分。 Reference will now be made in detail to the exemplary embodiments embodiments In addition, the same or similar reference numerals or components used in the drawings and the embodiments are used to represent the same or similar parts.
圖1是依照本發明一實施例的音訊播放裝置的電路方塊圖。請參照圖1。此實施例的音訊播放裝置100可以是收音機(radio)，其包括USB連接埠110、OTG(On-To-Go)控制器120、記憶體130以及微控制器MCU。OTG控制器120耦接USB連接埠110，微控制器MCU耦接至OTG控制器120與記憶體130。其中OTG控制器120可以支持USB協會所制訂的USB OTG的主機模式協定。 1 is a circuit block diagram of an audio playback device in accordance with an embodiment of the present invention. Please refer to Figure 1. The audio playback device 100 of this embodiment may be a radio, which includes a USB port 110, an OTG (On-To-Go) controller 120, a memory 130, and a microcontroller MCU. The OTG controller 120 is coupled to the USB port 110, and the microcontroller MCU is coupled to the OTG controller 120 and the memory 130. The OTG controller 120 can support the host mode agreement of the USB OTG established by the USB Association.
當更新音訊播放韌體時，音訊播放裝置100外部的移動式儲存媒體(removable storage media)170電性連接至USB連接埠110，OTG控制器120可以控制USB連接埠110的連結，而使音訊播放裝置100當作主機(host)，並且移動式儲存媒體170當作周邊裝置(peripheral)。如此一來，微控制器MCU與OTG控制器120可以從移動式儲存媒體170下載音訊播放韌體(firmware)，並將韌體儲存至記憶體130內。 When the audio playback firmware is updated, the removable storage media 170 external to the audio playback device 100 is electrically connected to the USB port 110, and the OTG controller 120 can control the connection of the USB port 110 to enable audio playback. Device 100 acts as a host and mobile storage medium 170 acts as a peripheral. In this way, the microcontroller MCU and the OTG controller 120 can download the audio playback firmware from the mobile storage medium 170 and store the firmware into the memory 130.
更新韌體後，將移動式儲存媒體170與USB連接埠110 的電性連接移除，微控制器MCU可以讀取記憶體130的資料，並且執行新的音訊播放運作。 After updating the firmware, the mobile storage medium 170 is connected to the USB port 110 The electrical connection is removed and the microcontroller MCU can read the data of the memory 130 and perform a new audio playback operation.
因此，本實施例的音訊播放裝置100可以在不需要電腦的情況下直接與任何使用USB連接埠110的外部移動式儲存媒體170進行韌體的更新，可以符合各個不同地區的規範。音訊播放裝置100具有獨立作業的特性。並且更新韌體時不需要電腦，所需的整體裝置的擺放空間也較小，可以不用受到場地的限制。在現今講求效率的時代更具實用性。 Therefore, the audio playback device 100 of the present embodiment can perform firmware update directly with any external mobile storage medium 170 using the USB port 110 without requiring a computer, and can conform to specifications of different regions. The audio playback device 100 has the characteristics of independent work.

It is more practical in today's era of efficiency.
在又一實施例中，音訊播放裝置100還可以包括紅外線傳輸介面140以及遙控器145。紅外線傳輸介面140耦接至微控制器MCU。遙控器145以無線傳輸信號方式與紅外線傳輸介面140連接，用以控制OTG控制器120或微控制器MCU來進行相應的運作。如此亦可達成與上述實施例相類似的功效。 In still another embodiment, the audio playback device 100 may further include an infrared transmission interface 140 and a remote controller 145. The infrared transmission interface 140 is coupled to the microcontroller MCU. The remote controller 145 is connected to the infrared transmission interface 140 in a wireless transmission signal manner for controlling the OTG controller 120 or the microcontroller MCU to perform corresponding operations. This also achieves similar effects to the above embodiments.
再者，音訊播放裝置100還可以包括按鍵鍵盤150與顯示單元160。按鍵鍵盤150與顯示單元160耦接至微控制器MCU。可以將按鍵鍵盤150與使用者介面做結合，如此的按鍵鍵盤150可以控制OTG控制器120或微控制器MCU來進行相應的運作。顯示單元160可以顯示音訊播放裝置100的韌體更新訊息或各種播放訊息。 Furthermore, the audio playback device 100 may further include a key pad 150 and a display unit 160. The key pad 150 and the display unit 160 are coupled to the microcontroller MCU. The push keypad 150 can be combined with the user interface. Such a push keypad 150 can control the OTG controller 120 or the microcontroller MCU to perform corresponding operations. The display unit 160 can display a firmware update message or various broadcast messages of the audio playback device 100.
此外，記憶體130可以是快閃記憶體(flash memory)，但不以此為限。移動式儲存媒體170可以是USB隨身碟172或快閃記憶卡(flash memory card)174。其中快閃記憶卡(flash memory card)174的規格，諸如：SM卡(Smart Media Card)、MMC卡(Multi Media Card)、MS卡(Memory Stick Card)、SD卡(Secure Digital Card)、CF(Compact Flash)卡。 In addition, the memory 130 may be a flash memory, but is not limited thereto. The removable storage medium 170 can be a USB flash drive 172 or a flash memory card 174. Among them, the specifications of the flash memory card 174, such as: SM card (Smart Media Card), MMC card (Multi Media Card), MS card (Memory Stick Card), SD card (Secure) Digital Card), CF (Compact Flash) card.
