An earphone device includes a speaker unit, an inner housing body and an outer housing body. The inner housing body covers the speaker unit through an insert molding technique. The outer housing body covers the inner housing body through the insert molding technique.

Earphone device

A speaker device includes a housing body, a speaker driver and a passive radiator. The housing body is formed with a first sound hole and a second sound hole respectively opening in two opposite directions. The speaker driver is disposed in the housing body, is located adjacent to the first sound hole, and is adapted to generate sound. The passive radiator is disposed in the housing body, is located adjacent to the second sound hole, and is adapted to generate sound. The first sound hole and the second sound hole are adapted for respectively allowing the sound generated by the speaker driver and the sound generated by the passive radiator to travel out from the housing body respectively in two opposite directions therethrough.

Speaker device

A passive diaphragm assembly includes a counterweight member, a first diaphragm and a second diaphragm. The first diaphragm and the second diaphragm are spaced apart from each other, are connected respectively to opposite ends of the counterweight member, and cooperate with the counterweight member to define an air space thereamong.

Passive diaphragm assembly

An apparatus for measuring brightness transmitted by a light-emitting display unit of a laser telescope and observed by the user's eyes comprises a focusing unit (), a sensor unit (), a processing unit () and a display unit (). A method of measuring brightness includes the steps of: providing a constant color temperature to simulate the external light; providing a tool platform and locating the apparatus for measuring brightness and the laser telescope under test thereon; further providing a light-impermeable cover to cover the laser telescope and the apparatus for avoiding the external light interfering with the measurement of brightness; then turning on the laser telescope and enabling it to range; picking up the light of a reticle and a measured value transmitted from the light-emitting display unit by means of the apparatus for measuring brightness; and at last, displaying the measured value on the display unit of said apparatus for measuring brightness.
