摘要： The present invention discloses a hybrid electrostatic headphone module, with the hybrid electrostatic headphone module disposed in the interior of a left and a right ear cup of a stereo headphones. The hybrid electrostatic headphone module is assembled as a single unit from a traditional moving coil type headphone unit and an electret headphone unit (E-STAT), which are respectively responsible for medium-low frequency bands and medium-high frequency bands. A frequency divider assembled from a frequency division capacitance and a drive transformer divides a complete signal into medium-high frequency and medium-low frequency bands, which are then respectively supplied to high and low frequency sound speakers for output therefrom.

摘要： The present invention is to provide a thin type vacuum chamber device, wherein two hollow slabs are fastened by a claw fastener to form a thin type simple structure that can maintain a high vacuum state, and wherein the air inside the chamber is pumped out to attain a vacuum state with a high pressure suction activity. The thin-chamber design of the present invention can decrease the number of the components and reduce the cost. The special assembly design of the vacuum chamber of the present invention can effectively decrease the length of the transmission cable and thus can reduce signal attenuation and noise interference. The present invention has the advantage of convenient operation and is very suitable to a two-dimensional infrared sensor.
摘要翻译：本发明提供一种薄型真空室装置，其中两个空心板通过爪紧固件紧固以形成能够保持高真空状态的薄型简单结构，并且其中腔室内的空气被泵出以达到具有高吸力活性的真空状态。本发明的薄室设计可以减少部件的数量并降低成本。本发明的真空室的特殊组装设计可以有效地减小传输电缆的长度，从而可以减少信号衰减和噪声干扰。本发明具有操作方便，非常适用于二维红外传感器的优点。
