Description

[Technical Field]

[0001] This utility model relates to the technical field of structural components for electronic products such as audio equipment, and in particular to a support frame that offers a high level of user experience, strong stability, and is easy to extend and store. [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 support rod products generally consist of multiple short rods connected together, with the position defined by protrusions or annular grooves at the connection points. Over time, this can lead to decreased stability and affect usability. Furthermore, many existing portable speakers cannot be flexibly placed on the ground and generally need to be placed on a table or other flat surface, which does not adapt to a wide range of usage scenarios. Some speakers can be supported by rods, but these are generally limited by the flatness of the ground and cannot meet the needs of use on uneven surfaces. In addition, even with a structure that has a certain degree of adjustable support base, the playback angle cannot be adjusted flexibly to meet the needs of different audio-visual scenarios.

[0004] For example, the utility model patent with application number CN201620306258.9 and patent name "Multi-section Fixed Selfie Stick" specifically discloses a selfie stick, especially a multi-section fixed selfie stick, including a handle, a telescopic rod, and a phone fixing head. The telescopic rod is located at the top of the handle. The telescopic rod is composed of multiple short rods connected together, and a locking buckle is provided between each pair of adjacent short rods. The phone fixing head is located at the top of the telescopic rod. Additionally, two vertical strip-shaped grooves are provided on the upper part of one side of the handle, with a left support rod and a right support rod respectively located in each groove. A vertical strip-shaped groove is located on the lower part of the same side, with a tail rod located within the groove. This utility model, by providing locking buckles between each pair of adjacent short rods, ensures strong fixing strength between each section of the telescopic rod, allowing the selfie stick to support phones like the Samsung i9200. Furthermore, the left and right support rods allow the selfie stick to be tilted and placed on a flat surface, facilitating timed shooting with the phone placed on the ground or a table.

[0005] 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.

[0006] 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 rod structure needs to be improved and enhanced. [Utility Model Content]
