Description

Technical Field

[0001] The invention belongs to the technical field related to sound source localization, and in particular relates to a sound source localization system acquisition device with a freely transformable structure. Background Art

[0002] People often use hearing to determine the location of sound objects. There are three main issues in sound localization: one is the distance of the sound source, the second is the movement of the sound source, and the third is the direction of the sound source. The core issues of auditory sound are, first, the perception of sound; second, the analysis of sound signals (distinguishing frequency, intensity, sound quality, duration, and direction of the sound source). When accurate sound data is needed, relevant sensors, microphones and other equipment are needed to collect and monitor. The current sound source collection devices on the market do have major problems in portability and structural flexibility. Specifically, these problems are mainly reflected in the following aspects: 1. First, the lack of portability is a common problem faced by these devices. Due to their large size and heavy weight, these sound source collection devices are quite inconvenient to carry and use outdoors or in environments that require frequent movement. For professionals who need to collect sound on site for a long time, this undoubtedly increases their workload and limits their flexibility in collecting sound in different locations. In addition, for individual users or amateurs, these bulky devices often become obstacles for them to try sound collection technology; Secondly, structural fixation is another important problem faced by these devices. Due to the limitations of structural design, these sound source collection devices often lack sufficient flexibility and are difficult to quickly adjust or change the structure according to the needs of actual application scenarios. In certain specific environments, it may be necessary to place the device at a specific angle or position to obtain the best collection effect; however, due to the fixed structure, these devices often cannot meet these specific needs, resulting in unsatisfactory collection results.

[0003] These two major problems not only limit the application of sound source collection devices in specific environments and needs, but also restrict their development in broader fields; with the continuous advancement of sound collection technology and the increasing diversification of application scenarios, higher requirements are placed on the portability and structural flexibility of sound source collection devices.

[0004] 2. When the sound source positioning system collects sound sources, its placement status will have a certain impact depending on different environmental factors such as terrain. Because there must be no interference from factors such as personnel nearby, otherwise it will have an impact, so it can only rely on the stability of the collection device itself, so it needs to be supported and placed stably in various terrains.

[0005] Therefore, solving these problems and developing a more portable, structurally adjustable sound source collection device suitable for various terrains has become an important research direction in the current field of sound collection technology. Summary of the invention

[0006] The purpose of the present invention is to provide a sound source positioning system acquisition device with a freely transformable structure.

[0011] Furthermore, through holes are provided on the installation box outside the four corners of the through slot, and bolts are inserted through the outside of the box body and pass through the through holes into the installation box, and nuts are screwed on the bolts in the installation box.

[0012] Further, two relatively short side surfaces of the connecting rod 1, the connecting rod 2, the connecting rod 3, the connecting rod 4, the connecting rod 5, the connecting rod 6, the connecting rod 7, the connecting rod 8 and the connecting rod sleeve are provided with two upper and lower distributed limiting holes; and an L-shaped spring piece is also fixed on the side surface of the connecting rod 1, the connecting rod 2, the connecting rod 3, the connecting rod 4, the connecting rod 5, the connecting rod 6, the connecting rod 7 and the connecting rod 8 below the limiting hole, and a buckle is fixed on the upper part of the outer peripheral surface of the spring piece; The buckle on the outer spring sheet of connecting rod one is snapped into the limiting hole in connecting rod two, the buckle on the outer spring sheet of connecting rod two is snapped into the limiting hole in connecting rod three, the buckle on the outer spring sheet of connecting rod three is snapped into the limiting hole in connecting rod four, the buckle on the outer spring sheet of connecting rod four is snapped into the limiting hole in connecting rod five, the buckle on the outer spring sheet of connecting rod five is snapped into the limiting hole in connecting rod six, the buckle on the outer spring sheet of connecting rod six is ​​snapped into the limiting hole in connecting rod seven, the buckle on the outer spring sheet of connecting rod seven is snapped into the limiting hole in connecting rod eight, and the buckle on the outer spring sheet of connecting rod eight is snapped into the limiting hole in the connecting rod sleeve.
