Embodiment Construction

[0022] In order to make the technical means, creative features, objectives and effects of the invention easy to understand, the present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, a wrapped guide tube structure, such as figure 1 and figure 2 As shown, a wrapped guide tube junction 1, the wrapped guide tube structure 1 is applied on the horn 2, the wrapped guide tube structure 1 includes a guide tube 3 and a guide tube wrapped outside the guide tube The casing 4.

[0024] Sleeve 4 comprises a circular tubular sleeve front end 41 for fixing the guide tube, a sleeve rear end 42 for matching the surface section size of the sound outlet hole on the horn 2, a smooth connection front end and rear end The middle end 43 of the hollow casing at the end. The middle end 43 of the casing is a funnel-shaped hollow shape, and may also be a pyramid-shaped hollow transition shape.

[0025] The guide tube 3 i...

Abstract

The invention relates to the acoustics field and discloses a packaged guide tube structure applied to a horn. The packaged guide tube structure comprises a guide tube and a sleeving packaged outside the guide tube, wherein the sleeving comprises a round piping sleeving front end used for fixing the guide tube, a sleeving back end used for being in matching with a surface cross section dimension of a sound outlet hole arranged on the horn, and a hollow sleeving middle end in smooth connection with the front end and the back end. Compared with the prior art, the structure utilizing the sleeving to package the guide tube is utilized to replace a flange welding structure in the prior art, the guide tube is mounted in a mode of sleeving the sleeving during use, and a problem of a potential failure risk of a moving-iron horn generated because of flange surface welding or glue sealing during assembling the guide tube with the moving-iron horn in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of acoustics, in particular to an enveloping guide tube structure. Background technique [0002] The guide tube of the moving iron horn is used to collect and transmit sound. It is a necessary part in the application of most moving iron horns. The assembly of the guide tube and the moving iron horn body, including the position, sealing, etc. will affect the actual performance of the moving iron horn, so the guide tube is also a very critical part. The existing guide tube design consists of a flange surface (welded on the side of the sound hole of the moving iron horn and isolated from the outside world by glue). Since the guide tube needs to be centered and the consistency of the position must be ensured, when assembling the guide tube , corresponding positioning fixtures and welding equipment are required. During the welding process, whether it is resistance welding or laser welding, spatter will be generated. The...
