Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and more specifically, to a portable speaker with a retractable handle. Background Technology

[0002] In scenarios such as outdoor camping, street performances, and family gatherings, portable speakers have become core audio devices due to their "sound-on anytime" feature. Their portability, protective performance, and ease of use directly determine the user experience. There are many types of speakers on the market, and most of the large speakers are equipped with retractable handles, such as trolley-style speakers. Utility model patent CN220629498U discloses a portable trolley speaker, including a speaker body. A base is fixedly connected to the bottom of the speaker body. Several support blocks are fixedly connected to the bottom of the base near the left side, and several pulleys are installed on the bottom of the base near the right side. A side plate is fixedly connected to the top of the base near the right side. Two telescopic rods are embedded in the right side of the side plate. With the addition of a handle, pulleys, support blocks, and a leather pad, when the speaker body needs to be moved, the handle can be gripped and pulled upwards, causing the handle to extend the telescopic rods. Then, tilting the telescopic rods causes the side plate to tilt, which in turn tilts the base, causing the support blocks and leather pads at the bottom to move away from the ground. Then, the handle can be pulled, and the entire speaker can be moved using the bottom pulleys. This is more convenient than traditional speaker bodies that require manual handling. While the aforementioned technical solutions have their advantages, most portable speakers with retractable handles still have some shortcomings in use. For example, the jacks, interfaces, volume control knobs, and other components are all mounted on the top of the speaker, and most speakers lack corresponding dust protection components on the top, leaving these components exposed. Prolonged exposure to the elements causes dust to accumulate on these parts, and dust entering the interfaces can affect subsequent electrical connections, such as USB flash drives not being recognized by the USB port or audio cables malfunctioning. Therefore, we propose a portable speaker with a retractable handle. Utility Model Content

[0018] Please see Figures 1-4 This utility model provides a technical solution: a portable speaker with a retractable handle, including a speaker body 1 and a retractable lifting handle 10 installed on the back of the speaker body 1. The retractable lifting handle 10 is a conventional technology, such as the retractable handle on a suitcase, and does not need to be described in detail. Two symmetrical rollers 14 are installed on one side of the bottom of the speaker body 1, and two symmetrical support legs 13 are installed on the other side of the bottom of the speaker body 1. The length of the retractable lifting handle 10 can be adjusted according to usage needs. When moving, the rollers 14 help to roll and save effort. When placed, the support legs 13 ensure that the speaker body 1 is stable and does not tilt, making it convenient to carry.

[0019] In this embodiment, a waterproof baffle 15 is fixedly installed on the top surface of the speaker body 1, and a dust cover 2 is hinged to the top surface of the speaker body 1. A socket groove 20 is provided on the inner side of the dust cover 2, and the socket groove 20 is fitted onto the waterproof baffle 15. Multiple electrical sockets 11 are provided on the top surface of the speaker body 1, and a volume adjustment knob 12 is also provided on the top surface of the speaker body 1. The waterproof baffle 15 protects the electrical sockets 11 and the volume adjustment knob 12 inside.

The cable can be used without opening the dust cover, which solves the contradiction of "protection and cable use cannot be taken into account" in traditional speakers and is suitable for outdoor performances and other scenarios.

[0021] Specifically, a transparent protective plate 22 is detachably installed on the front of the dust cover 2. The transparent protective plate 22 is a transparent plate structure, which allows users to observe the usage status of the electrical socket 11 and the position of the volume adjustment knob 12 without opening the dust cover 2. A rectangular frame 21 is fixedly installed on the inner wall of the dust cover 2. The transparent protective plate 22 is glued to the rectangular frame 21 with waterproof adhesive. The rectangular frame 21 and the waterproof adhesive fix the transparent protective plate 22 to ensure a stable connection and a certain degree of waterproofness, thereby improving the convenience and protection of use.

[0022] Furthermore, a storage basket 3 and a water cup box 30 are fixedly installed on one side of the speaker body 1. The water cup box 30 is located below the storage basket 3. The storage basket 3 can store accessories such as USB flash drives and audio cables to prevent accessories from being lost. The water cup box 30 can hold beverages to meet the drinking needs in outdoor scenarios. The two have a clear division of labor, which improves the storage practicality of the speaker and reduces the trouble of carrying an extra storage bag.

[0023] In addition, the front panel of the cup holder 30 is provided with multiple water drainage holes 31 near the bottom. The top of the water drainage holes 31 extends to the bottom wall of the cup holder 30. The water drainage holes 31 are set at a downward tilt of 30 to 45 degrees. If the cup leaks, the water can flow out in time through the drainage holes 31, avoiding water from soaking the speaker body 1 or contaminating the accessories, and ensuring the safety of the equipment. Moreover, the cup holder 30 is located on the side of the speaker body 1 that is not connected to its interior, so that the water drained from the water drainage holes 31 will not enter the speaker body 1.

[0024] Finally, it should be noted that the speaker body 1, electrical jack 11, volume control knob 12, and other components of this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.
