DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0024] The utility model provides a kind of technical scheme, a wireless sound post, including sound post shell 1, protective net 2, card seat 3, assembly seat 4, hinged lug 5, air cylinder 6, support arm 7, connecting arm 8, mounting lug 9, counterweight chassis 10, spring 11, U-shaped frame 12, mounting table 13, roller 14, recess 15, screw rod 16, nut 17 and through slot 18:

[0025] Please refer to Figure 1 , the front of sound post shell 1 is equipped with protective net 2, please refer to Figure 2 , the lower part of the left and right sides of sound post shell 1 is equipped with card seat 3, please refer to Figure 3 , the outside of card seat 3 is equipped with assembly seat 4, the inside of sound post shell 1 is equipped with audio input module, frequency modulation module, power amplifier module, antenna system, loudspeaker, audio amplifier, control module, power management module, processor and storage unit, recess 15 is formed in the upper side of the rear of sound post shell 1, flexible pad is laid in the inside of recess 15, rubber pad is laid in the bottom end of sound post shell 1;

[0026] Please refer to Figure 4 , hinged lug 5, is connected in the upper and lower left and right sides of the outside of assembly seat 4, the inside of upper hinged lug 5 is equipped with air cylinder 6 by bearing, the inside of lower hinged lug 5 is inserted with support arm 7 by bearing;

[0027] A connecting arm 8 is installed on the outer end of the support arm 7. Each connecting arm 8 has a mounting ear 9 on its outer end. A counterweight base 10 is inserted into the lower inner side of each mounting ear 9 via a bearing. The outer end of each cylinder 6 is connected to the upper inner side of the mounting ear 9 via a bearing. A spring 11 connects the bottom of the connecting arm 8 to the inner upper surface of the counterweight base 10. A U-shaped frame 12 is connected to the middle of the bottom of each cylinder 6. The extension and retraction of the cylinder 6 causes the support arm 7 to swing up and down, which in turn causes the counterweight base 10 to move downwards and contact the ground. This allows the support arms 7 and the counterweight base 10 to support the bottom left and right sides of the sound column housing 1, preventing it from tipping over or shaking due to wind or external forces during use. This improves the quality and safety of the sound column and avoids impact damage to the internal components of the sound column housing 1 caused by tipping. It also keeps the sound column housing 1 vertical, preventing changes in the broadcast area and broadcast angle when it tipps over, thus improving the broadcast quality of the sound column. Please refer to [link / reference]. Figure 2 The internal slots of both the card holder 3 and the mounting base 4 are I-shaped. The external corners of the card holder 3 are rounded. Both the upper and lower ends of the card holder 3 are connected to screws 16, and nuts 17 are screwed onto the outside of each screw 16. The diameter of the nuts 17 is larger than the width of the card holder 3. Through slots 18 are provided on the left and right sides of the bottom of the sound column housing 1, corresponding to the positions of the nuts 17. The outside of the nuts 17 is decorated with anti-slip textures. Please refer to [link / reference]. Figure 5 The lower rear side of the sound column housing 1 is connected to a mounting platform 13. The rear side of the mounting platform 13 is inclined, and rollers 14 are installed on both the left and right sides of the rear of the mounting platform 13.

[0028] This design uses the extension and retraction of cylinder 6 to drive the support arm 7 to swing up and down, which in turn drives the counterweight chassis 10 to move downwards and contact the ground. Thus, the support arms 7 on both sides and the counterweight chassis 10 support the bottom left and right sides of the sound column shell 1, preventing it from tipping over or shaking due to wind or external interference during use. This improves the quality and safety of the sound column and avoids the problem of impact damage to the internal components of the sound column shell 1 caused by tipping. It also keeps the sound column shell 1 in a vertical position, avoiding the problem of changes in the broadcast area and broadcast angle when it tipps over, thereby improving the broadcast quality of the sound column.
