Embodiment Construction

[0016] The technical solution of the present invention will be described in further non-limiting detail below in combination with preferred embodiments and accompanying drawings.

[0017] Such as figure 1 and figure 2 As shown, an anechoic box for speaker testing provided by the present invention includes a box body 1 with an upward opening and a baffle plate 2 installed at the opening of the box body 1, and the box body 1 and the baffle plate 2 are fixedly connected by bolts.

[0018] The baffle 2 includes a speaker test hole 3 and a placement slot 4. The horn test hole 3 is used to place the speaker sound outlet, and the speaker sound outlet is located in the box body 1. A seal is attached to the contact between the test hole 3 and the placement slot 4 and the speaker. material, improve the sealing between the periphery of the horn and the baffle plate 2, and improve the noise reduction effect of the noise reduction box. A dodge door 5 is provided on the side of the box b...

Abstract

The invention discloses a silencing box for loudspeaker testing, which comprises a box body (1) with an upward opening, and is characterized in that a barrier plate (2) is fixedly installed at the opening, the barrier plate (2) is provided with a loudspeaker test hole (3) and a placement groove (4), and the inner wall and the outer wall of the box body (1) and the barrier plate (2) are attached with a sound-absorbing cotton layer (10) and a sound insulation surface layer (11) therebetween. According to the invention, the loudspeaker to be tested can be quickly fixed and abutted with the silencing box for testing, the junction of the loudspeaker and the silencing box is high in sealing degree, the double-layer sound insulation enclosure structure is adopted, shock absorbers are arranged below the platform, and the shock absorption and sound elimination effect of the silencing box is better.

Description

technical field [0001] The invention relates to the technical field of noise reduction facilities, in particular to an anechoic box for horn testing. Background technique [0002] After the loudspeaker is assembled, it needs to be tested for its acoustic performance. This kind of testing equipment requires a smaller space and can be tested quickly and effectively. In order to ensure airtight performance and acoustic characteristics, the general speaker test is to put the speaker to be tested into the anechoic box, and the sound from the speaker is received by the microphone inside the anechoic box, and the loudness and frequency spectrum are tested. This type of test is less efficient and is not suitable for acoustic performance testing of speakers on the production line. Contents of the invention [0003] The object of the present invention is to aim at the above-mentioned defects in the prior art, and provide an anechoic box for speaker testing, which has a good anechoi...
