Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and in particular to a foldable modular speaker. Background Technology

[0002] A speaker is an electroacoustic transducer that converts audio electrical signals into sound signals. Through its built-in speaker unit, it can convert digital or analog audio signals transmitted from devices such as mobile phones, computers, and players into sounds that people can hear. It is widely used in music production, recording studios, and other scenarios, providing audio professionals with a real and reliable sound reference.

[0003] Application No. 202420222028.9 discloses a novel foldable speaker, comprising a first speaker body and a second speaker body. The first speaker body includes a first outer shell, a first speaker, and a main board, both of which are fixed within the first outer shell. The second speaker body includes a second outer shell and a second speaker, both of which are fixed within the second outer shell. The main board is electrically connected to both the first and second speakers. One side panel of the first outer shell and one side of the second outer shell are hinged together, allowing the first outer shell to rotate relative to the second outer shell to fold or unfold the first speaker body. The first and second speakers are respectively disposed within the first and second outer shells, and the hinged connection between the first and second outer shells allows the first and second speaker bodies to be folded or unfolded, facilitating storage and portability.

[0004] The above solution has shortcomings in use. When the first speaker body and the second speaker body are unfolded, a stable connection is not formed between them. Once an accidental collision occurs, the angle between the first speaker body and the second speaker body will change, which will directly affect the acoustic layout of the speaker and seriously reduce the immersion and clarity of audio playback. Therefore, we provide a foldable modular speaker. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] As attached Figure 1 With appendix Figure 2 As shown: A foldable modular speaker includes a set of speaker bodies 1, which are hinged together by a hinge. Each speaker body 1 has a protective pad on one side that is close to the other. The hinge connects the speaker bodies 1, allowing them to be folded and unfolded. The protective pads prevent collision damage between the speaker bodies 1. Each speaker body 1 has a set of supports 6 fixedly connected to its bottom surface. Each set of supports 6 is symmetrically arranged. When the speaker bodies 1 are unfolded for use, the supports 6 can support the bottom of the speaker bodies 1, thereby ensuring the stability of the speaker body when playing audio.

[0027] As attached Figure 1 As shown: A set of speaker bodies 1 are all fitted with a support shell 4. The inner wall of the support shell 4 is provided with anti-collision pads. The support shell 4 can be used to hold the folded speaker body 1, thus forming external protection. A retractable handle 5 is installed on the back of the support shell 4. The support shell 4 can be pulled by the retractable handle 5 to facilitate the movement of the speaker body 1.

[0028] As attached Figure 1 With appendix Figure 3 As shown: A connecting component 2 is provided on the top of a group of speaker bodies 1. The connecting component 2 includes a connecting shaft 201 rotatably connected to the upper surface of each speaker body 1. A deflection plate 202 is fixedly connected to the top of each connecting shaft 201. A connecting plate 204 is rotatably connected above a group of deflection plates 202. By using the cooperation of the deflection plate 202 and the connecting plate 204, a connection can be formed between the tops of the speaker bodies 1. When the speaker bodies 1 are unfolded, the deflection plate 202 will rotate synchronously, and the angle between the deflection plate 202 and the connecting plate 204 will change synchronously.

[0029] As attached Figure 3 As shown: The connecting assembly 2 also includes a supporting structure disposed on each deflection plate 202 for stabilizing the deflection plate 202. The supporting structure includes a retaining screw 203 threaded to the upper surface of each deflection plate 202. The bottom end of each retaining screw 203 is rotatably connected to a contact plate 205. When the opening angle between the speaker bodies 1 reaches the optimal range for audio playback, after the angle is adjusted to the correct position, the retaining screw 203 is turned to push the contact plate 205 to descend smoothly. The contact plate 205 will tightly abut against the surface of the speaker body 1, thus stabilizing the deflection plate 202. The fixed locking mechanism ensures that the speaker bodies 1 remain stable after being unfolded, preventing angle changes and maintaining optimal sound field performance for audio playback. Each deflection plate 202 has a fixed support column 206 on its bottom surface, and an arc frame 207 is slidably connected to the outer surface of the bottom end of each support column 206. The bottom surface of each arc frame 207 is connected to the upper surface of the speaker body 1. By utilizing the cooperation between the arc frame 207 and the support column 206, the deflection plate 202 can be further positioned and stabilized, improving the positioning effect between the speaker bodies 1.

[0030] As attached Figure 1 With appendix Figure 4As shown: A lifting assembly 3 is commonly provided on the top of a group of speaker bodies 1. The lifting assembly 3 includes a U-shaped frame 301 fixedly connected to the upper surface of each speaker body 1, and a U-shaped handle 302 is commonly inserted into the interior of the group of U-shaped frames 301. When the speaker body 1 is folded, the U-shaped handle 302 is inserted into the U-shaped frame 301 to further ensure the stability of the speaker body 1 after folding. A set of connecting screws 303 are threaded to the bottom end of the U-shaped handle 302. Each connecting screw 303 is threaded to the U-shaped frame 301, and the connecting screws 303 connect the U-shaped handle 302 to the U-shaped frame 301, so that the U-shaped handle 302 is connected to the speaker body 1, making it convenient to lift the speaker body 1.

[0031] Working principle: When in use, first lift the U-shaped handle 302 to smoothly remove the speaker body 1 stored inside the carrier shell 4. Then, use a screwdriver to loosen the connecting screw 303 to remove the U-shaped handle 302. Then, manually deflect the speaker body 1. During this process, the deflection plate 202 will drive the connecting shaft 201 to rotate above the speaker body 1. At the same time, the angle between the deflection plate 202 and the connecting plate 204 will change synchronously until the unfolding angle between the speaker bodies 1 reaches the optimal range for audio playback. After the angle is adjusted, the user can turn the retaining screw 203 to push the contact plate 205 to descend smoothly. The contact plate 205 will tightly abut against the surface of the speaker body 1, thus completing the stable locking of the deflection plate 202. This ensures that the unfolding angle between the speaker bodies 1 is stable, preventing changes in the angle of the speaker body 1 and thus maintaining the best sound field effect for audio playback.
