Description

Technical Field

[0001] The present invention relates to the field of speakers, and particularly to a Bluetooth speaker for outdoor use. Background Art

[0002] The application prospect of outdoor Bluetooth speakers is very broad. Especially in the context of the continuous increase in people's dependence on outdoor activities, portable entertainment, and smart devices, both the market demand and technological innovation are accelerating. The rise of the outdoor lifestyle, such as camping, hiking, self-driving tours and other sports, has led to a surge in the global demand for outdoor sports, driving the demand for portable outdoor speakers.

[0003] Previously, outdoor Bluetooth speakers based on Bluetooth technology have been restricted by many uncontrollable outdoor environmental factors. For example, weather and electromagnetic interference, high humidity environments such as rain / water mist may absorb the 2.4GHz signal, resulting in delays or disconnections; lightning / strong electromagnetic fields, extreme weather or near high-voltage power lines may cause instantaneous signal interference; signal occlusion by obstacles, etc. However, with the development of Bluetooth information technology, these problems have been well solved. For example, the shell design takes into account both waterproofing and signal penetration, selects non-metallic material antenna areas, installs signal amplifiers, and dynamically enhances the transmission power; adopts multi-antenna MIMO technology to disperse the signal reception path, designs the top / side antenna layout, and reduces signal occlusion when placed on the ground, etc.

[0004] However, up to now, outdoor speakers are generally small speakers, which are not suitable for current outdoor gathering activities. Large speakers lack portability, and when used outdoors in the open air, the current sound propagation effect is also not ideal. Therefore, the present invention provides a Bluetooth speaker for outdoor use, which takes into account the open-air characteristics of the outdoors, has portability, and ensures the directional propagation effect of the sound effect. Summary of the Invention

The collar is sleeved on the hoop seat, and a bent rack is connected to the collar; a second motor is connected to the side wall of the hoop seat, and a second gear is connected to an output shaft of the second motor, and the second gear meshes with the bent rack. By controlling the rotational output of the second motor, the rotation of the top cover can be controlled, so that the top cover presents an inclined state, and then the sound wave propagating in the reverse direction can be reflected to the forward propagation area.

[0011] Further, a polyester fiber sound absorption layer is provided on the inner wall of the top cover. By adjusting the angle of the reflection surface and using the sound absorption material, the generation of standing waves is jointly suppressed.

[0012] Further, a reflector is slidably provided on the top cover, and a handle position is provided on the side of the reflector exposed outside the top cover. The function of the reflector is to extend the reflection area of the top cover and increase the reflection area of the sound wave.

The purpose is to push the elastic detent out of the card slot by pressing the elastic button to release the locking of the reflector. The function of the elastic detent is also to keep it on the inner wall of the top cover and not easily slide out.

[0014] Further, an arc-shaped slide bar seat is connected to the top cover. A slide bar is provided on the slide bar seat. Slide cylinders are slidably provided on both sides of the slide bar. Limit caps are connected to both ends of the slide bar on both sides. A spring sleeved on the slide bar is provided between the slide cylinder and the limit cap.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, a specific embodiment of the present invention will be elaborated in detail with reference to the attached Figures 1 - 6 drawings.

[0025] Refer to the attached Figures 1 - 4, A Bluetooth speaker for outdoor use, including a base 1, a support 2 is connected to the bottom of the base 1, an electric push rod 3 is connected to the support 2, the output shaft of the electric push rod 3 is connected to a lifting seat 4, the middle of the base 1 is a through groove, and the lifting seat 4 can perform a lifting action at the through groove. There are multiple guiding grooves 101 on the base 1, a supporting leg 5 is integrally connected to the lifting seat 4, and the supporting leg 5 cooperates with the guiding groove 101 to guide the lifting of the lifting seat 4.

[0026] A straight rack 6 is connected to the supporting leg 5, a shaft seat 7 is connected to the side of the base 1, a rotating shaft 8 is provided on the shaft seat 7, a gear 9 is key-connected to the rotating shaft 8, the gear 9 meshes with the straight rack 6, and a side plate 10 is also key-connected to the shaft seat 7. The shaft seat 7, the rotating shaft 8, the gear 9, and the side plate 10 form a rotating whole. An audio speaker 11 is provided on the lifting seat 4. The audio speaker 11 is a cylinder or an elliptical cylinder, and a hoop seat 12 is sleeved thereon. A top cover 13 is connected to the hoop seat 12.

[0027] The Bluetooth speaker for outdoor use of the present invention has the characteristics of being easy to carry and protect. In the non-use state, the electric push rod 3 has no output, the lifting seat 4 fits on the base 1, and the two form the sealed bottom of the overall outdoor Bluetooth speaker. The support 2 serves as the support feet of the outdoor Bluetooth speaker, and all the side plates 10 are in the retracted state. The side plates 10, the top cover 13, and the fitting lifting seat 4 and base 1 form the outer shell of the overall outdoor Bluetooth speaker. When using the audio speaker, the electric push rod 3 is controlled to act to lift the lifting seat 4. When the lifting seat 4 rises, the supporting leg 5 also rises accordingly. Through the meshing transmission of the straight rack 6 on the supporting leg 5, the gear 9 rotates, and then the side plates 10 are driven to rotate around the rotating shaft 8 to open the side plates 10 to complete the opening state.

[0028] The outdoor Bluetooth speaker of the present invention can lift the audio speaker 11 to a certain height when starting, which has a better propagation effect. And when outdoors, the elevated audio speaker can avoid the erosion of flowing water stains on the ground surface. During the process of lifting and opening, the side plates 10 on the side are synchronously driven to rotate downward and open. The opened side plates 10 can reach the ground surface and can be supported on the ground surface by ground nails, playing a role in resisting side winds to stabilize the outdoor Bluetooth speaker.

[0029] A handle 14 is connected to the top cover 13, which serves as the acting part for the user to carry the outdoor Bluetooth speaker for easy carrying.

[0030] Refer to the appendix Figure 2 and Figure 5The lifting seat 4 is provided with a bevel gear 15, the middle of the bevel gear 15 is keyed to a shaft column 16, the top of the shaft column 16 is connected to a mounting plate 17, and the clamping seats 12 at both ends of the speaker 11 are connected to the mounting plate 17; the lifting seat 4 is connected to a first motor 18, the output shaft of the first motor 18 is connected to a first gear 19, and the first gear 19 is meshed with the bevel gear 15. By controlling the rotation output of the first motor 18, the rotation angle of the speaker 11 can be controlled, and the directional propagation of the speaker in any direction of 360° is realized.

[0031] There are many ways to lay out the speakers for outdoor activities. The main one is a central layout to propagate sound waves in all directions. In this way, the hoop seat 12 can be directly disassembled, and the hoop seat 12 and the top cover 13 can be removed together to achieve 360° sound wave transmission; or, the sound waves can be propagated in a direction. At this time, the top cover 13 can be used in this embodiment to reflect the sound waves, so that the reverse propagating sound waves propagate in the same direction as the forward propagating sound waves, but it is necessary to pay attention to reducing the generation of standing waves.

[0032] Reference Figure 2 and Figure 5 Specifically, the top cover 13 is connected with a collar 20, which is sleeved on the clamp seat 12, and a curved rack 21 is connected to the collar 20; the side wall of the clamp seat 12 is connected with a second motor 22, and the output shaft of the second motor 22 is connected with a second gear 23, which meshes with the curved rack 21. By controlling the rotation output of the second motor 22, the rotation angle of the collar 20 on the clamp seat 12 can be controlled, and the top cover 13 can be controlled to rotate, so that the top cover 13 is tilted, and the reverse propagation sound waves can be reflected to the forward propagation area.

[0033] The top cover 13 is in an inclined state, and the back sound waves are directed to the front through the inclined reflective surface. At the same time, a polyester fiber sound-absorbing layer is provided on the inner wall of the top cover 13. This embodiment suppresses the generation of standing waves through the dual solutions of adjusting the angle of the reflective surface and using sound-absorbing materials.

[0034] Reference Figure 2 A reflective plate 24 is slidably provided on the top cover 13, and a handle position 241 is provided on the side of the reflective plate 24 exposed to the top cover 13. The reflective plate 24 can be pulled out of the top cover 13 by the pulling force acting on the handle position 241. The function of the reflective plate 24 is to extend the reflection area of ​​the top cover 13 and increase the reflection area of ​​the sound wave.

[0035] Reference Figure 2 and Figure 4, a chute is provided on the top cover 13, and a card slot 131 is provided at the end of the chute. An elastic latch 242 is connected to the reflector 24, and the elastic latch 242 can slide on the chute. When the reflector 24 is pulled out, the elastic latch 242 slides on the chute. When it reaches the card slot 131, the elastic latch 242 is inserted into the card slot 131 under its own elastic force to achieve position locking. An elastic button 34 is connected to the top cover 13 at the card slot 131. By pressing the elastic button 34, the elastic latch 242 can be pushed out of the card slot 131 to release the locking of the reflector. The function of the elastic latch 242 is also that when the overall Bluetooth speaker is in the retracted state, it maintains its position against the inner wall of the top cover 13 and does not easily slide out through the extrusion effect with the chute wall.

[0036] Reference appendix Figure 2 and Figure 6 , in this embodiment, a lateral sound collection component that expands laterally is also provided on the top cover 13, aiming to reflect the lateral sound waves to the target area. Specifically, an arc-shaped slide bar seat 25 is connected to the top cover 13, a slide bar 26 is provided on the slide bar seat 25, sliding cylinders 27 are provided on both sides of the slide bar 25, limit caps 28 are connected to both ends of the two sides of the slide bar 26, a spring 29 sleeved outside the slide bar 26 is provided between the sliding cylinders 27 and the limit caps 28, and a sound collection rotating cylinder 30 is rotatably connected to the sliding cylinder 27. A torsion spring 31 is provided at the connection between the sound collection rotating cylinder 30 and the sliding cylinder 27; a guide rail 32 is connected to the lifting seat 4, and the top of the sliding cylinder 27 abuts against the guide rail 32, and the sliding cylinder 27 and the guide rail 32 are always in contact and extrusion state.

[0037] The guide rail 32 presents a symmetric V shape with a high middle and low sides. During the rotation of the top cover 13, the sliding cylinder 27 rotates with the top cover 13 and is gradually pushed to both sides under the action of the guide rail 32, so that the connected sound collection rotating cylinder 30 extends to both sides and converges towards the Bluetooth speaker under the action of the torsion spring 31. During this process, the spring 29 is gradually compressed; when it needs to be retracted, the top cover 13 rotates and resets under the action of the second motor 22. At this time, under the reset elastic force of the spring 29, the sliding cylinder 27 is always pressed tightly against the guide rail 32, and the sound collection rotating cylinder 30 rotates under the action of the speaker 11, and the torsion spring 31 stores energy until it resets.

[0038] The outdoor Bluetooth speaker of the present invention has a good directional sound transmission effect. It can direct the sound wave to propagate through the top cover 13, the reflector 24, and the sound collection rotating cylinder 30. Moreover, multiple groups of outdoor Bluetooth speakers can be used to cover the sound transmission area, resulting in better sound effects.

[0039] Reference appendix Figure 1The photovoltaic panel 33 is connected to the side panel 10, and the electric control module is connected to the base 1, so as to improve the endurance of the audio system through renewable energy. The side panel 10 has four groups in the circumferential direction, and is inclined after being unfolded. Although it cannot be adjusted with the change of the solar altitude angle after being fixed to the ground, no matter how the overall audio system is installed, the side panel 10 can receive sunlight.

[0040] The outdoor Bluetooth speaker of the present invention uses Bluetooth technology to ensure that it does not need to be connected to various cables when in use, and is convenient to operate. The entire speaker is in a storage state when not in use, and the side panels and the top cover form a shell to protect the speaker, isolate dust, etc., and extend the service life of the speaker. At the same time, the folded state reduces space occupation and is easy to carry; when the entire speaker is in use, the speaker is lifted during the unfolding process, and the side panels are linked to unfold and supported on the ground, which stabilizes the entire device. The speaker can then adjust the propagation angle and propagate in a directional manner to the target area, and then the top cover is rotated to tilt it. During the rotation process, the radio drum on the top cover is pushed out in a linked manner, and finally the reflector is pulled out to achieve a better radio effect.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
