        全球智能耳機發展分析:AI技術、藍牙技術提升智能無線耳機品質發展[圖]

        2019年04月01日 13:26:13字號:T|T

            智能耳機離人的語言器官較近,語音識別難度大幅度降低。智能耳機中語音交互功能的加入,使人們對智能設備的溝通開始從指令性向個人化進行轉變。由于與耳機的溝通形式更像是與電話中的朋友交談,人與智能耳機的互動更自然、更便捷。

            一、智能耳機現狀

            傳統耳機的降噪只要依靠被動降噪,利用耳機耳罩物理結構設計和物理材料的選擇極大減少外界聲音的進入。智能耳機則可以通過配備的微型揚聲器和芯片,可以通過產生與噪音相反的聲音消除噪音的影響。

            智能耳機將在無線連接、智能降噪、語音交互和生物監測等領域發揮重要的作用,未來將成為智能手機的標配。蘋果airpods的入場,帶來了智能耳機市場的變革,目前布局智能耳機的既有智能手機巨頭也有傳統耳機商,主要涉及的公司有蘋果、三星、索尼、谷歌等,整個智能耳機行業在2020年將可能成為一個超過400億美元的市場。

            AirPods的火爆銷售正式打開了TWS真無線藍牙智能耳機的市場,而“無線”成為消費者最為關注的耳機特性。

            耳機因其良好的便攜性成為不可替代的電子產品,智能耳機的出現使耳機的使用場景增多,并迅速吸引消費者并占據市場。在國內,蘋果AirPods發布后連續進入中關村統計的耳機關注度前十,甚至多次奪取第一、第二的位置。

            TWS耳機主要由芯片、揚聲器、麥克風和多個傳感器構成,AirPods集成了28個組件及數百個元器件,復雜度大幅提升。

            二、智能耳機的發展趨勢

            智能耳機將成為下一個智能硬件風口,耳機作為當前使用量最大以及使用時間最長的外設之一,人工智能加持應用價值大幅日升,未來智能耳機將會承接智能手表等部分可穿戴設備的市場。

            耳機已經由數字化往無線化發展,并且無線耳機技術已經成熟。無線耳機普遍都采用放置耳機的充電盒充電,解決了無線耳機的續航痛點。無線耳機佩戴的舒適度和穩定性也經過耳機廠商不斷嘗試研發出了符合人體工學的產品。

            隨著智能語音的高速發展,多個領域都出現了和語音功能結合的智能產品。智能語音作為人機交互的底層技術,識別率的大幅提高極大促進了人工智能的發展。多款智能耳機因為語音助手的成熟,而能加載自家語音助手實現耳機的智能化。

            藍牙技術的升級提升了TWS耳機等無線產品的使用體驗,藍牙5.0的功耗更低;覆蓋半徑達300米,是藍牙4.2的4倍;傳輸速度最高達24Mbps,是藍牙4.2的兩倍;還能配合WIFI實現室內定位。藍牙Mesh技術也打破傳統實現了“多對多”設備間的信號傳輸。三、傳感器和AI技術

            隨著技術的進一步發展,未來TWS耳機可能在工業、醫療、ToB等領域取得更大市場空間。蘋果專利顯示,未來耳機可能搭載心率檢測技術,集成更多的傳感器實現監測心臟、血壓等功能。而另一份專利則描述了依靠傳感器和麥克風實現用戶控制環境音的技術,這項技術甚至可以調節耳壓。未來TWS耳機技術升級方向還可能有電容傳感器的集成——蘋果專利顯示集成了電容傳感器的耳機可以檢測用戶手指的觸摸以執行操作。

            語音交互是屏幕和鍵盤的首選替代品,支持AI語音助手成為手機的延伸無疑是TWS耳機最大的賣點。目前各大手機廠商推出的TWS耳機大多支持各自手機的語音助手。

            2019年語音助手在智能手機的滲透率會超過50%,在2023年將達到90%。因此未來語音控制市場前景良好,而TWS耳機將成為語音交互的重要入口。

            智能耳機類比的還是內容和服務生態。受運動健身、健康監測、消費娛樂等需求驅動,智能耳戴式設備集成音樂播放器、無線連接和多種傳感器,并帶有防水、降噪和高保真等新增功能,開始登上舞臺。綜合應用傳感體系、智能語音交互和智能推薦算法等人工智能解決方案也將出現在智能耳機中,成為推動市場的關鍵因素。
