Abstract: A sound insulating device used to carry out audio testing of a mobile phone is provided. The sound insulating device includes a sound speaker, a sound receiver, a clamping platform clamping the mobile phone thereon and a sound insulating chamber. The sound insulating chamber receives the sound speaker and the sound receiver and the clamping platform therein. The sound insulating chamber is enclosed by several sound insulating boards. Each sound insulating board includes a sound absorbing layer, a cushion layer and an aluminium-alloy layer combined together. The cushion layer is sandwiched between the absorbing layer and the aluminium-alloy layer.

Abstract: A testing apparatus (100) for testing a touch screen used in an electronic device is described. The testing apparatus includes a base (20), a testing device (13), a holding mechanism (10), and a control module (12). The testing device includes a testing platform (131) carrying the touch screen, a positioning board (133) and testing members (135) positioned on the positioning board. The holding mechanism is operatable to hold the touch screen on the testing platform during the testing members testing the touch screen. The control module can control the testing members to test the touch screen.

Abstract: A sound testing device (100) includes a processor (10), a mouth simulator (30), an ear simulator (40) and a soundproof container (50). The processor includes a first testing module (131) for test sound components which transform sound signals into electronic signals, a second testing module (132) for test sound components which transform electronic signals into sound signals, and a controlling module (12) connected to the first testing module and the second testing module. The mouth simulator is connected to the processor and sends sound signals input into test sound components. The ear simulator is connected to the processor and receives sound signals output from test sound components. The soundproof container receives the mouth simulator and the ear simulator therein.
