Description

Technical Field

[0001] This utility model relates to the field of audio equipment technology, and in particular to a long-battery-life Bluetooth speaker. Background Technology

[0002] With the development of Bluetooth technology and the increasing demand for outdoor activities, portable Bluetooth speakers are becoming increasingly popular due to their wireless connectivity and portability, and are widely used in outdoor leisure, sports, travel and other scenarios.

[0003] However, most portable speakers currently on the market still have significant limitations in terms of product form and mounting methods. For example, in mobile scenarios such as hiking or walking the dog, users usually need to hold the speaker by hand or rely on a simple lanyard to hang it on their wrist or backpack. This not only occupies the user's hands and affects freedom of movement, but also poses a risk of slipping. If the speaker is placed in a pocket or bag, it will be obstructed by the fabric or bag, significantly weakening the sound propagation and sound quality. In addition, the outdoor environment is complex and changeable, and the speaker is prone to damage to the outer shell and failure of internal components due to accidental collisions or drops. Although some products have tried to use additional structures such as silicone protective cases to improve protection, these structures often affect ease of operation, heat dissipation performance, and overall appearance, and cannot simultaneously meet the needs of multiple wearing methods and secure mounting. Therefore, there is an urgent need for a Bluetooth speaker solution that integrates long battery life, efficient protection, multi-scenario adaptability, and convenient wearing.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0037] Example 1: Basic Structure and Assembly Relationship

[0038] See Figures 2 to 7 The long-battery Bluetooth speaker in this embodiment mainly consists of two parts: the speaker body 10 and the detachable snap-fit ​​component 20.

[0039] The outer shell 11 of the speaker body 10 is typically made of high-strength, lightweight engineering plastics (such as ABS or PC) to ensure overall portability. Annular anti-collision protrusions 12 are provided on its front and back edges. These protrusions are preferably made of soft, elastic materials such as TPU (thermoplastic polyurethane elastomer) or silicone and are bonded to the outer shell 11 via two-color injection molding or post-assembly to form a closed buffer ring. The anti-collision protrusions 12 slightly protrude from the surface of the outer shell 11, thus defining the first groove 14 and the second groove 15 together with the outer shell. The first groove 14 is located on the front of the speaker and contains a speaker outlet 141 covered by a protective mesh. This recessed design protects the outlet from direct impact without obstructing effective sound propagation.

[0040] At each of the four corners of the outer casing 11, there is a shock-absorbing protrusion 13. Each shock-absorbing protrusion 13 is also made of an elastic material (such as silicone or soft TPU), and its core feature is an arc-shaped protrusion 131 that curves from the front of the casing to the back. The contour of the arc-shaped protrusion 131 is adapted to the corners, and a through groove 132 is formed on its outer wall. This groove can be used to thread a lanyard 30 (such as...) Figure 8 As shown in the image, this provides another simple way to carry it.

[0041] The detachable snap-fit ​​assembly 20 includes:

[0042] A base plate 21, the shape of which roughly matches the outline of the back of the speaker body 10.

[0043] Multiple snap-fit ​​pieces 23 are fixed to the base plate 21. The number and position of the snap-fit ​​pieces 23 correspond to the anti-collision protrusions 13 at the corners of the speakers. Each snap-fit ​​piece 23 includes an arc-shaped limiting baffle 231 that matches the curvature of the outer wall of the arc-shaped protrusion 131, and a limiting protrusion 232 extending inward from the upper edge of the baffle.

[0044] On the base plate 21, a limiting protrusion 24 is also provided, the position of which corresponds to the second groove 15 on the back of the speaker. The limiting protrusion 24 has a second magnetic part 241 embedded inside, which can be a permanent magnet or an iron metal sheet.

[0045] A connecting strip 22 with one end connected to the base plate 21, the free end of which is provided with a first zipper part 221 (e.g., male or female chain).

[0046] The assembly process is as follows:

[0047] The user aligns the speaker body 10 with the base plate 21, aligning the arc-shaped protrusions 131 of each anti-collision bump 13 with the entrance of the locking component 23. Pressing the speaker downwards causes the outer wall of the arc-shaped protrusion 131 to slide in and abut tightly against the inner wall of the arc-shaped limiting baffle 231. Simultaneously, the limiting protrusion 232 of the locking component 23 engages below the top edge of the arc-shaped protrusion 131, forming a mechanical lock. During this process, the limiting protrusion 24 on the base plate 21 also simultaneously embeds into the second groove 15 on the back of the speaker, causing the second magnetic attraction part 241 within the limiting protrusion 24 to attract the first magnetic attraction part 151 (also a permanent magnet or metal sheet) pre-embedded at the bottom of the second groove 15. This dual fixing mechanism of mechanical locking and magnetic attraction ensures that the speaker will not accidentally detach from the locking assembly even under severe shaking during use.

[0048] The disassembly process is the opposite: the user only needs to hold the edge of the speaker with their fingers, and gently pry it upwards to overcome the magnetic attraction and make the limiting protrusion 232 slide over the top of the arc protrusion 131 to remove the speaker body 10 from the base plate 21. The process is simple and quick.

[0049] Example 2: Usage scenario when connected to a pet vest

[0050] See Figure 1 This demonstrates the usage state of the present invention connected to the pet vest 40.

[0051] The pet vest 40 is a common style on the market, with a second zipper 401 sewn on its back or shoulder to match the first zipper 221. The user only needs to align the first zipper 221 on the connecting strap 22 of the snap-fit ​​assembly 20 with the second zipper 401 on the pet vest and pull it closed to securely fix the entire audio system to the pet's back.

[0052] During outdoor activities such as dog walking, music can accompany both pets and owners. The speaker's 141-degree upward-facing output ensures unobstructed sound transmission. A lithium-ion polymer battery provides long battery life, meeting the needs of extended outdoor use. This design completely frees the owner's hands, enhancing the overall experience.

[0053] Example 3: Application scenario of connection with arm loop belt

[0054] See Figure 9 This demonstrates the usage state of the present invention connected with the arm ring belt 50.

[0055] The armband 50 can be made of materials such as nylon or elastic fiber, and has a length adjustment structure 51, such as a Velcro closure, which allows users to easily adjust the tightness according to the size of their arms, ensuring comfortable and secure wear. A second zipper 501 is also sewn onto the armband 50.

[0056] The user first connects the clip assembly 20 to the armband via a zipper, then wears the armband 50 on their arm and adjusts it to a suitable tightness. This allows the user to enjoy high-quality music while running, cycling, or exercising without needing to hold a phone or speaker, making exercise safer and more convenient.
