Description
本創作係關於一種耳機裝置,尤指一種頭戴式耳機裝置。This creation is about an earphone device, especially a headphone device.
目前市面上所販售耳機裝置的類型包括:耳塞式耳機、耳道式耳機及頭戴式耳機等。與耳塞式耳機及耳道式耳機相比,由於頭戴式耳機能完整地包覆耳朵,且配戴時較為舒適,因此需長時間配戴的耳機裝置,例如:電競耳機、監聽耳機或音樂耳機等多採用頭戴式的形式製作。The types of earphone devices currently sold on the market include earphones, earphones, and headphone. Compared with earbuds and ear canal earphones, since the earphones can completely cover the ears and are more comfortable to wear, earphone devices that need to be worn for a long time, such as gaming earphones, monitoring earphones or Music headphones, etc. are mostly made in the form of head-mounted.
於現有技術中,如圖1之(i)所示,耳機裝置2的揚聲單元20會被安裝於封閉型的音腔室C2中。而為讓喜好重低音的使用者於使用頭戴式耳機時可聆聽到更多的低沉聲響,許多頭戴式耳機會於揚聲單元的音腔室上開孔,如圖1之(ii)所示,耳機裝置3的揚聲單元30安裝於音腔室C3中,且音腔室C3具有與外界環境相連通之直通型的氣體通道P3。如此一來外界環境的氣流便可經由直通型之氣體通道P3導入音腔室C3中,以進行氣流的交換。藉由氣流的交換,可讓揚聲單元30之振膜的行程增大,使揚聲單元30產生更多的低頻響應,讓使用者可自耳機裝置3中獲得更多的低頻音壓。In the prior art, as shown in (i) of FIG. 1 , the
然而,雖然音腔室C3上的氣體通道P3有助於外界氣流的導入和交換,但也會讓外界環境中的聲響或雜音沿著氣體通道P3進入耳機裝置3之中,導致使用者在聆聽重低音的音效時,也同時會受到更多外界噪音的影響及干擾,而無法獲得良好的聽覺體驗。However, although the gas channel P3 on the sound chamber C3 is helpful for the introduction and exchange of the external air flow, it also allows the sound or noise in the external environment to enter the
