Description

[Technical field]

[0001] The utility model relates to the field of earphones, in particular to an earphone acoustic testing device. [Background technology]

[0002] A Bluetooth headset is a small device based on Bluetooth technology. You only need to hide this lightweight device next to the headset to make free calls without directly using communication devices (mobile phones, computers, etc.). A Bluetooth headset applies Bluetooth technology to hands-free headphones, allowing users to avoid the entanglement of annoying wires and make calls easily in various ways.

[0003] Bluetooth headsets are extremely widely used, and each type of headset needs to undergo various performance tests before leaving the factory, including tests on the earpiece and microphone. At this time, a headphone acoustic test device is needed.

[0004] At present, the existing Bluetooth headset acoustic test devices on the market do not have the function of adjusting the position of the artificial mouth. For example, patent application number: CN201922179578.9 discloses a Bluetooth headset acoustic test device, which comprises a base, an adjustment plate is installed at the middle position of the upper surface of the base, two adjustment rods are symmetrically installed on the upper surface of the adjustment plate, and an artificial mouth is installed on the inner sides of the two adjustment rods, and symmetrical support rods are installed on the upper surface of the base, and a placement table is installed on the inner sides of the two support rods, and the placement table is located in front of the artificial mouth. However, this type of test device fixes the artificial mouth on one side of the placement table, and the position of the artificial mouth cannot be adjusted, which is inconvenient for acoustic testing of the headset at different positions. Therefore, it is necessary to provide a Bluetooth headset acoustic test device.

[0005] The utility model is proposed in view of the deficiencies in the prior art. [Contents of the utility model]
