Hand emulator and acoustic testing system

Abstract

Provided is a hand emulator and an acoustic testing system. The hand emulator includes: a main support configured to support a device under test, the main support includes a palm, a thumb, an index finger, a middle finger, a ring finger and a little finger that are movably arranged at an end of the palm; a stopper including a plurality of limit pillars, at least some of the plurality of limit pillars are arranged on the palm, several limit pillars of the plurality of limit pillars enclose to form an accommodating space, and the device under test is limited within the accommodating space. The hand emulator can measure the frequency response of the speaker and/or the microphone of the device under test, emulate acoustic characteristics similar to the user's hand, and accurately and repetitively position the device under test, which improves existing measurement standards and creates new testing methods.
