      Qualcomm推出QCC5141耳塞參考設計平臺,助力制造商開發真無線耳塞

      2020年11月7日

      Qualcomm products mentioned within this post are offered by Qualcomm Technologies, Inc. and/or its subsidiaries.

      我們發布的《音頻產品使用現狀調研報告2020》(State of Play Report 2020)顯示,有73%的受訪者對完全脫離線纜束縛而帶來的自在體驗感興趣。與2019年相比,真無線耳塞的普及率幾乎翻倍,在全球范圍內實現了從23%到42%的增長。盡管音質仍然是最為重要的購買驅動因素,但數據顯示,消費者同時也非常關注無縫用戶體驗、佩戴舒適性以及更長的續航時間等特性。
      為幫助耳機廠商高效快速地取得市場先機,Qualcomm近期推出了真無線耳塞參考設計平臺。該平臺基于旗艦版QCC5141藍牙音頻SoC,包含了耳塞硬件、全面軟件解決方案以及調試工具,幫助我們的客戶開發下一代真無線設備并改變用戶與個人音頻設備連接、溝通、交互的方式。

      匠心設計,支持無縫用戶體驗

      用戶使用真無線耳塞的使用次數、使用時間都在增加,耳塞的應用范圍也越來越廣泛,如聽音樂、語音通話和手游等。隨著消費者愈加熟悉和依賴真無線耳塞,他們對耳塞的易用性和使用體驗的期望值也在不斷升高。根據《音頻產品使用現狀調研報告2020》,許多消費者對于無線耳塞與智能手機間的交互性表現出越來越濃厚的興趣,其中,35%的受訪者顯示出“高”或“極高”的興趣。在使用無線設備時,另一個消費者真正關心的因素是藍牙連接的穩定性。調研結果顯示,音頻中斷影響了近四分之一無線耳塞受訪者的購買決定。

      該耳塞參考設計支持我們最新的Qualcomm TrueWireless Mirroring技術,以幫助提供更無縫的用戶體驗和為兩個耳塞提供更好的整體連接性。即一只耳塞通過藍牙連接至手機,另一只耳塞則成為其“Mirroring”,并且這兩只耳塞可以在多個使用場景下快速切換。例如,從耳朵中取下和手機相連的耳塞之后,用戶無需任何操作,Mirroring耳塞便能接管與手機的連接,避免了音樂或語音通話的連接中斷。Qualcomm TrueWireless Mirroring技術還支持管理單一藍牙地址,在用戶將兩只耳塞與手機進行配對時,手機僅顯示一只耳塞設備以進行配對。

      集成主動降噪技術,提供沉浸式聆聽體驗

      該耳塞參考設計平臺同時還支持Qualcomm主動降噪(Qualcomm Active Noise Cancellation,簡稱ANC)技術。調查顯示,71 %的受訪者表達了對主動降噪這一功能感興趣。專用ANC硬件集成到系統級芯片中,支持外部環境音的超低時延透傳,讓用戶能夠對周圍環境擁有真正自然的感知。例如,當您一邊晨跑一邊聽音樂時,聽到往來行人車輛的聲音很重要,這樣能夠確保您的安全;當您在辦公室辦公時,您需能夠聽到同事叫你或者向你提問。

      高清音樂聆聽和清晰語音通話

      調查顯示,用戶對真無線設備的功能和體驗要求日益嚴苛。音質仍然是他們決定購買與否的第一要素。為幫助制造商滿足用戶對高清音樂聆聽和清晰語音通話的嚴格要求,Qualcomm耳塞參考設計平臺搭載Qualcomm aptX Adaptive技術cVc回音消除和降噪技術(Qualcomm cVc echo cancellation and noise reduction)。

      以獨特技術平臺,助力客戶靈活創新

      該耳塞參考設計平臺基于Qualcomm QCC5141藍牙音頻SoC,專為真無線耳塞和智能耳戴設備而優化,旨在提升真無線聆聽體驗。憑借強大的四核處理能力,QCC5141通過專用的應用處理器子系統、雙DSP架構、新一代音頻開發工具包(ADK)軟件、優化的開發工具,以及添加制造商自有或第三方軟件即可打造全新耳塞體驗的能力,讓我們客戶能夠靈活自由地開發耳塞產品。

      QCC5141耳塞參考設計平臺現已上市。
