Description

Technical Field

[0001] The present invention relates to the field of speakers, in particular to a portable speaker made of silica gel. Background Art

[0002] Defects of existing portable speaker products on the market

[0003] 1. Lack of portability

[0004] Difficult to compress: Although some portable speakers claim to be portable, their structural design lacks foldable or retractable functions, resulting in the inability to effectively reduce their size when not in use. They take up a large amount of space and are difficult to put into small spaces such as backpacks and pockets, making them inconvenient to carry.

[0005] Heavy weight: Speakers made of hard materials (such as plastic and metal) are heavy in nature, so even if they are small in size, carrying them for a long time will still increase the burden on the user.

[0006] 2. Poor sound quality

[0007] Weak bass effect: Many portable speakers pursue compact size and limited internal space, resulting in insufficient resonance space between the woofer and the cavity, unable to produce sufficient low-frequency response, and the bass performance is dry and weak.

[0008] Poor sound quality layering: The single-speaker design or unreasonable speaker layout results in insufficient separation between mid-high frequencies and low frequencies, muddy sound, and lack of layering.

[0009] Therefore, it is necessary to provide a portable silica gel speaker to solve the above technical problems. Summary of the Invention

[0010] In order to solve the above technical problems, the present invention provides a portable silicone speaker.

[0011] The present invention provides a portable silicone speaker, comprising a shell, wherein the shell comprises an upper shell, a corrugated silicone telescopic shell fixed to the bottom of the upper shell, and a base fixed to the bottom of the corrugated silicone telescopic shell. A circuit board is fixed inside the upper shell, an ordinary speaker is installed on one side of the circuit board, a mounting hole is provided at the center of the base, a woofer is installed in the mounting hole, and the woofer and the ordinary speaker are both electrically connected to the circuit board.

[0012] When in use, the corrugated silicone telescopic shell stretches its side length to enlarge the volume of the cavity between the woofer and the battery, making the bass effect produced by the woofer better. When not in use, the corrugated silicone telescopic shell is folded and stored to reduce the volume of the entire shell for easy carrying.

[0013] Preferably, a plurality of threaded barrels are provided inside the upper shell, and the circuit board is connected to the threaded barrels by screws.

[0014] Preferably, a sound outlet is provided on the top of the upper shell.

[0015] Preferably, a telescopic rod is installed between the upper shell and the base. The telescopic rod includes a sliding sleeve fixed to the top inner wall of the upper shell and a fixed rod fixed to the base, and the fixed rod and the sliding sleeve are slidably connected. The provision of the telescopic rod prevents the corrugated silicone telescopic shell from deforming horizontally, ensuring that the shell remains vertically stable.

[0016] Preferably, four of the threaded cylinders and four of the telescopic rods are provided.

[0017] Preferably, a battery connected to the circuit board wires is fixed on the side of the circuit board facing away from the ordinary speaker, and a charging interface is provided on the circuit board.

[0018] Preferably, protrusions are provided at the four corners of the base, and sound-emitting spaces are formed between adjacent protrusions.

[0019] Compared with the related art, the present invention has the following beneficial effects:

[0020] After stretching the corrugated silicone expansion shell, the volume of the cavity between the woofer and the battery becomes larger, which enhances the bass effect and makes the sound quality fuller.

[0021] Structural stability:

[0022] The design of the telescopic rod effectively prevents the corrugated silicone telescopic shell from deforming in the horizontal direction, ensuring the stability of the speaker during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Please refer to 1- Figure 5 , a portable silicone speaker

[0031] Structural design description

[0032] The overall structure of this portable silicone speaker is composed of a housing 1, which is divided into three parts: an upper housing 11, a corrugated silicone telescopic shell 12, and a base 13. The specific connection relationship is as follows:

[0033] Upper housing 11: As the main structure of the top of the speaker, a circuit board 2 is fixed inside it.

[0034] The corrugated silicone telescopic shell 12 is made of corrugated silicone material and is telescopic. The top of the shell is fixedly connected to the bottom of the upper shell 11 , and the bottom is fixedly connected to the top of the base 13 .

[0035] Base 13: serves as the bottom support structure of the speaker, and a mounting hole 131 is provided at the center thereof for mounting the woofer 4.

[0036] Internal component layout

[0037] Circuit Board 2:

[0038] It is fixed inside the upper housing 11 and connected to the upper housing 11 through four threaded barrels 5. Each threaded barrel 5 has a threaded hole, and the circuit board 2 is fixed to the threaded barrel 5 by screws to ensure the stability of the circuit board 2.

[0039] A common speaker 3 is mounted on one side of the circuit board 2, and a battery 8 is fixed on the other side. The common speaker 3 and the battery 8 are connected via wires on the circuit board 2 to achieve electrical connection.

[0040] Ordinary speaker 3:

[0041] Installed on one side of the circuit board 2, it is responsible for playing mid- and high-frequency sounds.

[0042] Subwoofer 4:

[0043] It is installed in the mounting hole 131 of the base 13 and connected to the circuit board 2 through wires, and is responsible for playing low-frequency sounds.

[0044] Battery 8:

[0045] It is fixed on the side of the circuit board 2 facing away from the ordinary speaker 3 to provide power support for the entire speaker.

[0046] Charging port 9:

[0047] It is arranged on the circuit board 2 and is used to charge the battery 8.

[0048] Telescopic structure and stability design

[0049] Corrugated silicone telescopic shell 12:

[0050] The corrugated silicone material is retractable. When the speaker needs to be used, the corrugated silicone telescopic shell 12 is stretched, increasing the overall height of the housing 1 and the volume of the cavity between the woofer 4 and the battery 8, thereby enhancing the bass effect.

[0051] When the speaker is not in use, the corrugated silicone telescopic shell 12 can be folded to reduce the overall height of the housing 1, making it easier to carry and store.

[0052] Telescopic rod 7:

[0053] It is installed between the upper shell 11 and the base 13 to prevent the corrugated silicone telescopic shell 12 from deforming in the horizontal direction and ensure that the shell 1 is in a vertically stable state.

[0054] The telescopic rod 7 is composed of a sliding sleeve 71 and a fixed rod 72 . The sliding sleeve 71 is fixed to the top inner wall of the upper shell 11 , and the fixed rod 72 is fixed to the base 13 . The fixed rod 72 is slidably connected to the sliding sleeve 71 .

[0055] Sound output and anti-slip design

[0056] Sound hole 6:

[0057] It is arranged on the top of the upper shell 11 and is used to spread the sound produced by the ordinary speaker 3.

[0058] Projection 10:

[0059] The four corners of the base 13 are each provided with a protrusion 10 , and sound outlet spaces are formed between adjacent protrusions 10 , which facilitate the propagation of low-frequency sounds generated by the woofer 4 .

[0060] The design of the protrusion 10 also increases the friction between the speaker and the placement surface, preventing the speaker from sliding and improving the stability of use.

[0061] Beneficial effects

[0062] Portability:

[0063] The design of the corrugated silicone telescopic shell 12 allows the speaker to be folded and stored when not in use, greatly reducing its volume and making it easy to carry and store.

[0064] Improved sound quality:

[0065] After the corrugated silicone telescopic shell 12 is stretched, the volume of the cavity between the woofer 4 and the battery 8 becomes larger, thereby enhancing the bass effect and making the sound quality fuller.

[0066] Structural stability:

[0067] The design of the telescopic rod 7 effectively prevents the corrugated silicone telescopic shell 12 from deforming in the horizontal direction, thereby ensuring the stability of the speaker during use.

[0068] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
