Description

[Technical Field]

[0001] This utility model relates to the technical field of structural components for audio products, and in particular to a support frame with outstanding application effects that is easy to fold and has flexible angle adjustment. [Background Technology]

[0002] As people's living standards continue to improve, music has become a major way for people to enhance their quality of life, regulate their mood, and relieve stress. At the same time, related music playback devices, such as speakers, have also seen significant improvements in terms of technology and user-friendliness, especially in sound quality and continuous use time. In order to make it easier to carry around when traveling, there are now many small portable speakers on the market with good sound quality.

[0003] However, existing technologies still have many shortcomings. For example, existing portable speakers cannot be placed flexibly on the ground and generally need to be placed on a table or other flat surface, which cannot adapt to more usage scenarios. Some speakers can be supported by poles, but they are basically limited by the flatness of the ground and cannot meet the needs of use on uneven ground. Secondly, even with a structure that has a certain degree of adjustable support base, it is not possible to flexibly adjust the playback angle to meet different audio-visual scenarios, etc.

[0004] For example, the utility model patent with application number CN201921033021.8 and patent title "An Ultra-thin Speaker Easy to Carry" specifically discloses an ultra-thin speaker that is easy to carry, relating to the field of speaker technology. It includes a shell, a mounting cavity, a first protective sleeve, a second protective sleeve, a support member, a support ring, a support strip, a buffer member, an elastic silicone ball, a first spherical buffer pad, a first elastic strip, a second spherical buffer pad, a second elastic strip, and an anti-slip strip. The shell has a cuboid structure. This utility model, by setting the first protective sleeve, the second protective sleeve, the support member, and the anti-slip strip, provides double protection for the exterior of the shell, supports the mounting cavity, effectively protects the internal components of the speaker, enhances breathability and heat dissipation, and features a mobile phone-style shell for easy handheld carrying. It also provides anti-slip properties and convenient use. The buffer member provides multiple elastic protections for the speaker's corners, effectively protecting them from damage if the speaker is dropped.

[0005] The aforementioned existing technical documents have improved the safety of the product to a certain extent, but they still have a series of shortcomings as mentioned above, and the audio structure needs to be improved and enhanced from an overall perspective. [Utility Model Content]
