手機連接LED藍牙音(yin)響沒聲(sheng)音(yin)怎么辦
當下，手機(ji)(ji)(ji)不(bu)僅是(shi)(shi)(shi)咱們(men)(men)彼此聯絡的(de)(de)工具，更是(shi)(shi)(shi)集娛樂(le)(le)休(xiu)閑(xian)為(wei)(wei)一體的(de)(de)智能(neng)(neng)設(she)(she)備，尤(you)其是(shi)(shi)(shi)作為(wei)(wei)音(yin)(yin)樂(le)(le)播映(ying)設(she)(she)備的(de)(de)運(yun)用更為(wei)(wei)常見，而手機(ji)(ji)(ji)藍(lan)(lan)牙(ya)(ya)音(yin)(yin)箱(xiang)(xiang)作為(wei)(wei)手機(ji)(ji)(ji)播映(ying)音(yin)(yin)樂(le)(le)的(de)(de)輔佐設(she)(she)備受到更多消(xiao)費(fei)者的(de)(de)青睞。那么，手機(ji)(ji)(ji)藍(lan)(lan)牙(ya)(ya)音(yin)(yin)箱(xiang)(xiang)銜接沒聲(sheng)響(xiang)(xiang)怎么辦呢？ 一、先查(cha)看藍(lan)(lan)牙(ya)(ya)音(yin)(yin)箱(xiang)(xiang)是(shi)(shi)(shi)不(bu)是(shi)(shi)(shi)與(yu)播映(ying)音(yin)(yin)樂(le)(le)的(de)(de)手機(ji)(ji)(ji)配(pei)對成(cheng)功，當咱們(men)(men)有兩個手機(ji)(ji)(ji)的(de)(de)時分，有可能(neng)(neng)藍(lan)(lan)牙(ya)(ya)音(yin)(yin)箱(xiang)(xiang)銜接的(de)(de)是(shi)(shi)(shi)另一個手機(ji)(ji)(ji)，而非咱們(men)(men)播映(ying)音(yin)(yin)樂(le)(le)的(de)(de)手機(ji)(ji)(ji)，這時分也會造成(cheng)藍(lan)(lan)牙(ya)(ya)音(yin)(yin)箱(xiang)(xiang)播映(ying)沒有聲(sheng)響(xiang)(xiang)； 二(er)、查(cha)看手機(ji)(ji)(ji)音(yin)(yin)
