Embodiment Construction

[0021] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be specifically described below in conjunction with the accompanying drawings and embodiments. The drawings in the following description are only some embodiments of the invention. For those skilled in the art, other drawings can also be obtained based on these drawings without creative effort.

[0022] When performing a pass-by noise test (or other tests with similar requirements) in a semi-anechoic chamber in the prior art, it is necessary to place two rows of microphones in parallel on both sides of the object under test, usually with a very long length. The traditional form of a single microphone stand is obviously very inconvenient in terms of distance, parallelism and height adjustment.

[0023] Based on the above considerations, the present invention designs a microphone bracket, which can fix multiple microphones o...

Abstract

The invention discloses a microphone support which comprises a bottom support frame, a horizontal adjusting device, a longitudinal support adjusting rod and a microphone clamping device, wherein the horizontal adjusting device is arranged on the bottom support frame, the longitudinal support adjusting rod is connected with the bottom support frame through the horizontal adjusting device, and the microphone clamping device is connected with the longitudinal support adjusting rod. A microphone queue is uniform by the aid of the microphone support to form a firm structure, and can be conveniently horizontally and longitudinally accurately adjusted, so that accurate acoustic testing can be performed in a semi-anechoic room.

Description

technical field [0001] The invention relates to the technical field of acoustic testing, and in particular to a microphone stand. Background technique [0002] A semi-anechoic chamber is an anechoic chamber with a reflective floor to simulate a semi-free space room. It is designed on the principle of doubling the effective size by using the total reflection ground as a mirror. In the semi-anechoic room, as long as the sound source is placed on the reflective ground, that is, when the sound source radiation surface is in the same plane as the ground, the sound propagation situation is the same as that in the conventional anechoic room. In fact, because the sound source has a certain scale, it is difficult to do this, but as long as the sound source is as close as possible to the reflecting surface, when h<r(h is the distance between the sound radiation surface and the ground, r is the distance between the receiving point and the sound source distance), the change law of ...
