Description

Technical Field

[0001] The utility model relates to the technical field of audio, in particular to a portable audio system. Background Art

[0002] Audio refers specifically to an audio system that produces sound from a combination of electrical equipment. In audio technology, sound quality includes three aspects: volume, pitch, and timbre. The volume of sound refers to the intensity and amplitude of the audio; the pitch of sound, also known as pitch, refers to the frequency of the audio or the number of changes per second; the timbre of sound refers to the overtones or harmonic components of the audio; audio is a music playback device that integrates power amplifier, playback, and speakers. With the improvement of the pace of modern people's lives, more and more urban people have chosen to do outdoor sports with their family or friends on weekends, such as camping, picnics, and adventures in the wild, to relieve their mental stress. When people engage in the above-mentioned outdoor activities, they often bring the aforementioned portable audio equipment so that they can always be accompanied by wonderful music during the entire outdoor activity.

[0003] In the related technology, a solution of a portable speaker (announcement number: CN219351906U) was discovered through searching. When in use, by setting an installation groove, a threaded connecting ring, a threaded limit pin, and a portable handle, when the speaker body needs to be carried and transferred, the staff only needs to hold the portable handle and apply a force to lift the speaker body and then transfer it. Because the threaded connecting ring is embedded in the bottom end of the inner wall of the installation groove, and the portable handle is connected to the threaded connecting ring through a threaded limit pin, it can provide convenience for the transfer of the speaker body, thereby enhancing the practicality of the device.

[0004] However, since the loudspeaker (i.e., speaker) of the speaker is exposed to the outside world when the speaker is used, objects from the outside may accidentally hit the loudspeaker when the speaker is carried or used, thus damaging the loudspeaker. This makes it difficult to protect the loudspeaker, and further, if the loudspeaker is not protected, the loudspeaker may be damaged by the impact, thereby shortening the service life of the loudspeaker and making it difficult to promote the speaker. In view of this, we have introduced a portable speaker. Utility Model Content
