Electrostatic discharge (ESD) phenomena have been known to mankind since the Greek
Empire when Thales of Miletus, one of the Seven Sages of Greece, noticed the attraction of
strands of hay to amber, leading to the coining of the word “electron.” Electrical discharge
and the guiding of electrical discharge (e.g., Lightning) was of interest to Benjamin Franklin
in the 1700s, with the invention of the Lightning rod. The Lightning rod was mankind’s first
effort to guide the electrical discharge current of a Lightning strike in a direction that would
not harm structures.
目前TWS 藍(lán)牙無(wú)線耳機(jī)已經(jīng)較為大眾接受,TWS藍(lán)牙耳機(jī)充電盒雖然是耳機(jī)附件，但是它的作用至關(guān)重要，由于耳機(jī)盒設(shè)計(jì)比較精致，體積較小，導(dǎo)致電池容量不高，需要長(zhǎng)途物流、靜默擱置，所以超低自放電是一項(xiàng)硬性指標(biāo).但目前TWS藍(lán)牙充電耳機(jī)盒大都還是使用micro USB 連接線來(lái)對(duì)藍(lán)牙無(wú)線耳機(jī)充電盒充電,使用者外出必須攜帶 Power Bank +micro USB, Type C (Android) + Lightning (iPhone) Apple等等線材,若是Power Bank 也是無(wú)線充電是否可以改善如此多線的麻煩事. 所以基于方便性及相容性將Semtech 無(wú)線充電RX 5W(Qi)方案導(dǎo)入無(wú)線耳機(jī)充電盒來(lái)應(yīng)用,也可以將無(wú)線充電耳機(jī)盒設(shè)計(jì)成防水防塵等級(jí)的無(wú)線充電盒.使用Semtech RX 5W(Qi)無(wú)線充電并可以相容于TX(Qi)無(wú)線充電板.
