As shown in fig. 5 and 6, in the embodiment, the article holders 2 of the two embodiments are mounted on the cabinet 1, and the article holders 2 of the same embodiment are mounted on the cabinet 1 by a T-shaped mounting bracket 5. In other embodiments, the article holders 2 of both embodiments may be mounted on the same T-shaped mounting bracket 5. The specific implementation mode is set according to the requirements of a user, the article clamping piece 2 is arranged on the mounting plate 51 through the corresponding universal sizing pipe 41, and the adjustment and the replacement of the article clamping piece 2 are greatly facilitated by the threaded connection mode.

As shown in fig. 5, 6, and 9, the mass of the entire audio device is large, and two persons or a cart are required for transportation, which makes the transportation difficult. For the removal of making things convenient for the stereo set, the stereo set is equipped with and removes wheel 61, specifically, one side of case 1 bottom is equipped with at least one and removes wheel 61 to be equipped with first supporting legs 62 corresponding every and remove wheel 61, the opposite side of case 1 bottom is equipped with at least one second supporting legs 63, the relative height of first supporting legs 62 to case 1 bottom equals the relative height of second supporting legs 63 to case 1 bottom, the relative height of first supporting legs 62 to case 1 bottom is greater than the relative height of removing wheel 61 to case 1 bottom, and half surrounds the removal wheel 61 that corresponds. Specifically to this embodiment, remove wheel 61 and first supporting legs 62 and respectively be equipped with two, second supporting legs 63 is equipped with threely, and three second supporting legs 63 are close to the stereo set front end in case 1 bottom and are the arc distribution setting, remove wheel 61 and correspond first supporting legs 62 and set up in case 1 bottom opposite side interval, and wherein first supporting legs 62 removes wheel 61 relatively and is close to second supporting legs 63. When the sound equipment needs to be moved, the sound equipment is laid down to one side of the moving wheel 61 until the moving wheel 61 contacts the moving surface, and meanwhile, the first supporting leg 62 and the second supporting leg 63 are separated from the moving surface to pull the sound equipment to move and dislocate; when placing the stereo, because the relative height of first supporting leg 62 to case shell 1 bottom is greater than the relative height of removal wheel 61 to case shell 1 bottom, remove the wheel 61 and not contact the removal face, the stereo is stably placed. In order to facilitate the movement of the audio, a handle part 64 is further arranged on the edge of the top of the cabinet 1 and one side corresponding to the moving wheel 61, the handle part 64 is integrally formed with the cabinet 1, the top and the side of the cabinet 1 corresponding to the handle part 64 are concavely communicated to form a containing cavity for containing the handle part 64, and the containing cavity is three-dimensional and is provided with an object placing table 65. In particular, in the present embodiment, the moving wheels 6, the grip portion 64 and the musical instrument board 81 are mounted/disposed on the same side of the cabinet 1. When moving, a user holds the handle part 64 with a hand penetrating into the accommodating cavity to pull, and skillfully sets the accommodating cavity into the object placing table 65, so that the equipment is simple in structure, and meanwhile, the user can place some small portable objects temporarily.

At the live broadcast of network or activity scene, the user uses the cell-phone to play audio frequency or record the video, with cell-phone 66 and microphone 67 centre gripping respectively in suitable article holder 2, stand position according to self, the operation habit and/or look up the habit, position state or record the angle through the universal calibrator 41 adjustment cell-phone 66 that corresponds, make self conveniently look over and operate, adjust the position of microphone 67 through the universal calibrator 41 that corresponds, can clearly pick up user's sound, therefore, the user can release both hands in the use and carry out other operations, for example do the demonstration at the speech in-process, hand action cooperation etc. in the live broadcast process, can also change the position at the periphery of stereo set according to the user demand. The stereo set can also use in meeting, teaching, and the user is with cell-phone 66 centre gripping in suitable article holder 2, conveniently looks over electronic manuscript such as lecture manuscript, and the user with microphone 67 centre gripping in suitable article holder 2, picks up user's sound through microphone 67, through broadcaster 13 enlargements broadcast for the audience can clearly hear, improves the on-the-spot effect.
