Description

Technical Field

[0001] This utility model relates to the technical field of outdoor speakers, and in particular to a Bluetooth speaker with outdoor lighting function. Background Technology

[0002] With the increasing popularity of outdoor sports, the outdoor equipment market is experiencing rapid growth, with outdoor lighting fixtures, outdoor speakers, and other equipment becoming increasingly popular among outdoor enthusiasts. To meet the need for portability in outdoor settings, these devices are typically designed to be small in size. However, while the smaller size brings advantages in portability, it also limits the functionality and usability of the equipment, resulting in poor performance.

[0003] Limited functionality: Traditional outdoor lighting and speakers are mostly designed independently, requiring users to carry multiple devices, increasing their burden.

[0004] Size versus performance conflict: To make them portable, devices are usually small in size, but this small size limits the low-frequency performance of speakers and the illumination range of lights.

[0005] Structural limitations: The rear acoustic chamber of the speaker has insufficient volume, resulting in poor low-frequency response; while the light fixture has limited luminous height, resulting in a small illumination coverage area.

[0006] Therefore, how to innovatively design outdoor equipment to expand its functions and improve its usability while maintaining a small size and portability has become an urgent technical problem to be solved. Utility Model Content

[0007] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0008] This utility model provides a Bluetooth speaker with outdoor lighting function, including a base component and a lamp post component fixedly connected to each other. The base component houses a sound-generating component and an electronic component. The electronic component includes a sound control circuit and a light control circuit. The sound-generating component has a speaker electrically connected to the electronic component and configured to emit corresponding sounds according to electronic signals from the sound control circuit. The lamp post component houses a light-emitting group and an energy storage battery. The energy storage battery is electrically connected to the electronic component, providing power to the electronic component, the sound-generating component, and the light-emitting group. The light-emitting group is electrically connected to the electronic component and configured to emit corresponding light according to electronic signals from the light control circuit. The lamp post component has openings at both its upper and lower ends. The lower opening near the base component communicates with the internal space of the base component, and the upper opening away from the base component has a passive radiator. The upper opening of the lamp post component is closed by the passive radiator, so that the internal space of the lamp post and the internal space of the base together form a sealed rear acoustic cavity for the speaker.

[0009] Furthermore: The base component has an annular groove around its top perimeter, and the bottom end of the side wall of the lamp post component is embedded in the annular groove to form a closed and fixed connection.

[0010] Furthermore, the lamp post component is also equipped with an axial support. The inner wall of the axial support is configured to fix and install the energy storage battery, and the outer wall is configured to install the light-emitting lamp assembly. The end of the axial support near the base component is provided with a radial base plate. The side of the radial base plate facing the base component is provided with a first protrusion. The radial base plate is fixedly connected to the top wall of the base component through the first protrusion, and a gap space is formed between the radial base plate and the top wall of the base component, so that the internal space of the base component and the internal space of the lamp post component are connected to each other.

[0011] Furthermore: a hollow bracket is provided on the top wall of the lamp post component, one end of which is fixed to the top wall of the lamp post component, and the other end is fixed to the end of the axial bracket away from the base component.

[0012] Furthermore: a diaphragm tube seat is provided at the upper opening of the lamp post component away from the base component. One end of the diaphragm tube seat is fixed to the top wall of the lamp post component, and the other end is provided with a diaphragm groove, configured to install a passive radiator.

[0013] Furthermore: the top wall of the lamp post component is provided with a second protruding post, and a top cap is installed on the second protruding post. The brim of the top cap is tilted at a certain angle towards the base component and extends outward to form a waterproof rim. The top cap is provided with an inner ring bracket corresponding to the position of the diaphragm tube seat. One end of the inner ring bracket is fixed to the top cap, and the other end is fixedly connected to the diaphragm tube seat, thereby assisting in the installation of the passive radiator.

[0014] Furthermore: the base component has a hollow side wall at the bottom and a solid side wall at the top. A speaker bracket is also provided between the hollow side wall and the solid side wall. The speaker is mounted vertically downward on the speaker bracket so that the speaker diaphragm faces downward and is aligned with the cavity formed by the hollow side wall, so that the sound emitted by the speaker can pass through the hollow side wall to propagate.

[0015] Furthermore, the top wall of the base component has an opening, thereby connecting the cavity enclosed by the solid side wall and the speaker bracket with the internal space of the lamp post component, together forming the rear sound cavity of the speaker.

[0016] Furthermore, a battery bracket is provided at the opening on the top wall of the base component, which is used to support and fix the energy storage battery.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Functional Integration and Space Optimization: This utility model innovatively combines outdoor lighting fixtures and outdoor speakers. The heavier sound-generating components are placed in the base component, which lowers the center of gravity of the equipment and enhances its stability. The lighter and taller lamp post component is fixed to the top of the base, and the light-emitting lamps in it can illuminate a wider area due to their higher position. At the same time, the space-consuming energy storage battery is placed inside the lamp post component, and the light-emitting lamps are arranged around the energy storage battery, which effectively reduces the overall size of the equipment and achieves functional integration and rational use of space.

[0019] 2. Sound quality optimization: By connecting the internal space of the lamp post component and the base component, the volume of the rear acoustic cavity of the speaker is increased, which shifts the low-frequency peak of the speaker's frequency response curve to the left and improves the low-frequency characteristics; a passive radiator is installed at the opening at the top of the lamp post component and the opening is closed to further enhance the low-frequency sound effect, optimize the sound quality, and make the music sound more pleasant.

[0020] 3. Stable structure and sealing: The top of the base component is provided with an annular groove, and the bottom of the side wall of the lamp post component is embedded in the groove to form a closed and fixed connection. A sealing ring can also be added to ensure that the internal space is sealed to form an effective rear sound cavity. The axial support inside the lamp post component is connected to the base component and the top wall of the lamp post through various fixing methods, which further improves the stability of the lamp post component and prevents shaking.

[0021] With the above improvements, this utility model innovatively combines outdoor lighting fixtures with speakers, rationally arranges components to achieve functional integration and space optimization, connects the internal space and adds passive radiators to optimize sound quality, and uses annular grooves, axial supports and other features to ensure structural stability and sealing, effectively solving the contradiction between the size and function of outdoor equipment and optimizing the user experience.

Detailed Implementation

[0033] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] Please see Figures 1 to 7In this embodiment of the present invention, a Bluetooth speaker with outdoor lighting function includes a base component 10 and a lamp post component 40 fixedly connected to each other. The base component 10 houses a sound-emitting component 20 and an electronic component 30. The electronic component 30 includes a sound control circuit and a light control circuit. The sound-emitting component 20 includes a speaker 21, which is electrically connected to the electronic component 30 and configured to emit corresponding sounds according to electronic signals from the sound control circuit. The lamp post component 40 houses a light-emitting lamp group 42 and an energy storage battery 17, which is electrically connected to the electronic component 30. The component 30, the sound-emitting component 20, and the light-emitting lamp group 42 are provided with power; the light-emitting lamp group 42 is electrically connected to the electronic component 30 and is configured to emit corresponding light according to the electronic signal of the light control circuit; the upper and lower ends of the lamp post component 40 are respectively provided with openings, the lower end opening near the base component 10 is connected to the internal space of the base component 10, and the upper end opening away from the base component 10 is provided with a passive radiator 22, so that the upper end opening of the lamp post component 40 is closed through the passive radiator 22, and the internal space of the lamp post and the internal space of the base together constitute the sealed rear acoustic cavity of the speaker 21.

[0035] Specifically, with the rise in popularity of outdoor sports, corresponding outdoor equipment has also seen significant development. For example, outdoor lighting fixtures and outdoor speakers are popular among outdoor enthusiasts. However, to facilitate portability, outdoor equipment is often designed to be relatively small. While this makes it convenient to carry, it also somewhat compromises its functionality and effectiveness. Therefore, how to redesign outdoor equipment to maintain a relatively small size while expanding its functionality and enhancing its usability is a technical problem worthy of research.

[0036] This invention combines an outdoor light fixture with an outdoor speaker design. The relatively heavy sound-generating component 20 is housed within the base component 10 at the bottom, ensuring the overall center of gravity of the device remains relatively low and enhancing its stability. Then, a portion of the relatively light and taller lamp post component 40 is fixed to the top of the base component 10, giving the light-emitting group 42 within the lamp post component 40 a higher position, allowing it to illuminate a wider area. Furthermore, a relatively space-consuming energy storage battery 17 is housed within the lamp post component 40, with the light-emitting group 42 arranged around it, further reducing the overall size of the device.

[0037] Secondly, in order to enhance the low-frequency sound of the speaker 21 and optimize its sound quality, it is preferable to connect the internal space of the lamp post component 40 with the internal space of the base component 10, so that the internal space of the lamp post component 40 forms the rear acoustic cavity of the speaker 21, thereby increasing the volume of the rear acoustic cavity of the speaker 21, shifting the low-frequency peak of its frequency response curve to the left, improving the low-frequency characteristics, and making the music emitted by the speaker 21 more pleasant.

[0038] Furthermore, to further enhance the low-frequency sound effect of the speaker 21, a passive radiator 22 is preferably installed at the upper opening of the lamp post component 40 away from the base component 10. The diaphragm area of ​​the passive radiator 22 is 1.2-1.5 times that of the speaker 21 diaphragm, and the upper opening of the lamp post component 40 is sealed, so that the internal space of the lamp post component 40, together with the passive radiator 22, forms a closed rear acoustic cavity, optimizing the sound quality of the speaker 21. The passive radiator 22 is a diaphragm unit without a drive circuit. It works in conjunction with the active unit to enhance low-frequency output. The passive radiator 22 is also called a passive radiator or a driven diaphragm, and its function is to assist the active unit of the speaker 21 in producing a richer and deeper low-frequency sound effect.

[0039] like Figure 3 and Figure 7 As shown, preferably, the base component 10 has an annular groove 11 at the top periphery, and the bottom end of the side wall of the lamp post component 40 is embedded in the annular groove 11 to form a closed and fixed connection.

[0040] Specifically, in order to form an effective rear acoustic chamber within the internal space of the lamp post component 40, it is necessary to ensure that the entire internal space is sealed. Therefore, an annular groove 11 is provided on the top of the base component 10, and the bottom of the side wall of the lamp post component 40 is inserted into the annular groove 11, so that the two cooperate with each other to form a sealing effect. A sealing ring can also be installed between the annular groove 11 and the side wall of the lamp post component 40 to further improve the sealing effect between the two.

[0041] Secondly, to allow light to pass through, the sidewalls of the lamp post component 40 are preferably made of a transparent material, such as transparent plastic. Furthermore, to soften the transmitted light, a diffuser 41 can be installed inside the sidewalls of the lamp post component 40. The diffuser 41 reflects the light multiple times, creating a diffuse reflection effect, thus making the light softer. For example, a polycarbonate material with a frosted surface or a diffusing agent can be used.

[0042] In addition, the side wall of the lamp post component 40 and the annular groove 11 can be fixed by adhesive bonding, snap-fit ​​connection or other fixed connection methods. Alternatively, the side wall of the lamp post component 40 can be embedded in the annular groove 11 by the fixed connection between the axial bracket 43 inside the lamp post component 40 and the base component 10, forming a relatively fixed limiting connection.

[0043] like Figure 3 , Figure 4 and Figure 6As shown, preferably, the lamp post component 40 is further provided with an axial support 43. The inner side wall of the axial support 43 is configured to fix the energy storage battery 17, and its outer side wall is configured to install the light-emitting lamp group 42. The axial support 43 is provided with a radial base plate 44 at one end near the base component 10. The radial base plate 44 is provided with a first protrusion 45 on the side facing the base component 10. The radial base plate 44 is fixedly connected to the top wall of the base component 10 through the first protrusion 45, and a gap space is formed between the radial base plate 44 and the top wall of the base component 10, so that the internal space of the base component 10 and the internal space of the lamp post component 40 are connected to each other.

[0044] Specifically, the axial support 43 extends a certain length along the axial direction of the lamp post component 40, and multiple LED light strips are evenly spaced on its outer side wall to form a light-emitting column of a certain height, thus optimizing its lighting effect. The radial base plate 44 extends a certain width along the radial direction of the lamp post component 40 to form an annular base plate of a certain width. Multiple first protruding posts 45 of a certain height are set on the bottom surface of the annular base plate. These first protruding posts 45 abut against the top wall of the base component 10 to form a gap space, allowing the gap space to connect the internal space of the base component 10 with the internal space of the lamp post component 40, forming an airflow channel that allows sound waves to propagate within the airflow channel. Preferably, the height of the gap space is set to 5-10 mm to ensure smooth airflow.

[0045] Secondly, the radial base plate 44 and the axial support 43 can be injection molded from plastic material using an integral molding process, while the first protruding post 45 and the top wall of the base component 10 can be fixedly connected by bolts. For example, the radial base plate 44 of the axial support 43 is fixed to the top wall of the base by at least 3 sets of bolts, and the bottom end of the lamp post side wall is fixed to the annular groove 11 by a double connection of snap fasteners and adhesive.

[0046] like Figures 3 to 5 As shown, preferably, a hollow bracket 50 is provided on the top wall of the lamp post component 40. One end of the hollow bracket 50 is fixed to the top wall of the lamp post component 40, and the other end is fixed to the end of the axial bracket 43 away from the base component 10.

[0047] Specifically, the hollow bracket 50 is set at the upper opening of the lamp post component 40 to fix the top wall of the lamp post component 40 to the axial bracket 43.

[0048] The fixing structure of the entire lamp post component 40 is as follows: First, the radial base plate 44 at the lower end of the axial support 43 inside the lamp post component 40 is fixedly connected to the top wall of the base component 10 through the first protruding post 45. Then, the top wall of the lamp post component 40 is fixedly connected to the upper end of the axial support 43 through the hollow support 50. The side wall and the top wall of the lamp post component 40 are in a fixed connection state or in a one-piece integral state. Therefore, it is equivalent to the side wall of the lamp post component 40 being fixedly connected to the upper end of the axial support 43, thereby completing the fixed installation of the entire lamp post component 40 and the base component 10.

[0049] To further improve the stability of the lamp post component 40, it is preferable to embed the lower end of the side wall of the lamp post component 40 into the annular groove 11 of the base component 10 to form a relatively fixed limiting connection and prevent the lamp post component 40 from shaking.

[0050] like Figures 2 to 5 As shown, preferably, the lamp post component 40 has a diaphragm tube seat 51 at the upper opening away from the base component 10. One end of the diaphragm tube seat 51 is fixed to the top wall of the lamp post component 40, and the other end has a diaphragm groove 52, which is configured to install a passive radiator 22.

[0051] Specifically, the diaphragm base 51 has a certain height, thereby creating a certain gap between the diaphragm of the passive radiator 22 and the top wall of the lamp post component 40, which facilitates the vibration of the diaphragm. In one embodiment, the passive radiator 22 can be directly installed on the side wall corresponding to the upper opening of the lamp post component 40, enclosing the entire side wall of the lamp post component 40 and forming a larger diaphragm area.

[0052] In another embodiment, to accommodate the top cap 60 on the top wall of the lamp post component 40, or to reduce the diaphragm area, an upper opening of a certain diameter can be made on the top wall of the lamp post component 40. A diaphragm tube seat 51 is then positioned corresponding to this upper opening, effectively placing the upper opening of the lamp post component 40 at the inner opening of the diaphragm tube seat 51. The passive radiator 22 is then mounted using the diaphragm tube seat 51. In this embodiment, the diaphragm tube seat 51 can be positioned on the top wall of the lamp post component 40 corresponding to the outer periphery of the hollow bracket 50. That is, the upper opening of the lamp post component 40 corresponds to the hollow section of the hollow bracket 50, meaning the hollow section is the upper opening. The sound wave airflow passes through the hollow section into the diaphragm tube seat 51 and interacts with the passive radiator 22 mounted on the diaphragm tube seat 51, driving the diaphragm of the passive radiator 22 to vibrate, thereby optimizing the sound quality of the speaker 21.

[0053] like Figure 2 , Figure 4 and Figure 5As shown, preferably, the top wall of the lamp post component 40 is provided with a second protruding post 53, and a top cap 60 is installed on the second protruding post 53. The brim of the top cap 60 is inclined at a certain angle toward the base component 10 and extends outward by a certain width to form a waterproof rim 61. The top cap 60 is provided with an inner ring bracket 62 corresponding to the position of the diaphragm tube seat 51. One end of the inner ring bracket 62 is fixed to the top cap 60, and the other end is fixedly connected to the diaphragm tube seat 51, thereby assisting in the installation of the passive radiator 22.

[0054] Specifically, the inner ring support 62 has multiple through holes on its side wall, which keeps the top space of the passive radiator 22 connected to the external space, facilitating the propagation of sound after the diaphragm vibrates. The top cap 60 and the second protruding post 53 can be fixedly connected by bolts.

[0055] Secondly, an outer ring bracket 63 is provided on the side wall of the top cap 60 corresponding to the lamp post component 40. The outer ring bracket 63 and the side wall of the lamp post component 40 are fixedly connected by a snap-fit ​​connection, allowing the outer ring bracket 63 to provide auxiliary support for the top cap 60. This also ensures that the outer ring bracket 63 and the side wall of the lamp post component 40 have a relatively uniform shape and size, enhancing the overall aesthetics. Understandably, multiple through holes also need to be provided on the outer ring bracket 63 to allow for normal airflow.

[0056] Additionally, a solar panel can be installed on the top of the cap 60 and electrically connected to the electronic component 30. By absorbing sunlight, it converts it into electrical energy to power the electronic components or charge the energy storage battery 17. The electronic component 30 also has a corresponding control circuit for the solar panel to control its operation.

[0057] like Figure 2 , Figure 3 and Figure 6 As shown, preferably, the base component 10 has a hollow sidewall 13 at the bottom and a solid sidewall 12 at the top. A speaker bracket 14 is also provided between the hollow sidewall 13 and the solid sidewall 12. The speaker 21 is mounted vertically downward on the speaker bracket 14, so that the diaphragm of the speaker 21 faces downward and is aligned with the cavity formed by the hollow sidewall 13, so that the sound emitted by the speaker 21 can pass through the hollow sidewall 13 to propagate.

[0058] Specifically, a rubber gasket can be provided between the speaker 21 and the speaker bracket 14 for sealing to prevent air leakage. A conical sound guide plate 15 can also be provided on the bottom surface of the base component 10, so that the sound waves emitted downward by the speaker 21 are guided by the conical sound guide plate 15 to propagate towards the hollow side wall 13, and then propagate in all directions through the hollow holes of the hollow side wall 13.

[0059] like Figure 3 , Figure 4 and Figure 7 As shown, preferably, the top wall of the base component 10 is provided with an opening, so that the cavity enclosed by the solid side wall 12 and the speaker bracket 14 is connected to the internal space of the lamp post component 40, and together they form the rear sound cavity of the speaker 21.

[0060] Specifically, to connect the internal space of the base with the internal space of the lamp post, a hole of a certain size needs to be made in the top wall of the base component 10. Airflow passes through the hole, then through the gap between the radial base plate 44 and the top wall of the base, entering the internal space of the lamp post. This airflow then interacts with the passive radiator 22 on the top wall of the lamp post, producing a more pleasant sound. That is, the sound waves generated by the vibration of the speaker 21 diaphragm sequentially pass through the opening in the top wall of the base and the gap in the radial base plate 44 into the lamp post, driving the passive radiator 22 to vibrate. Tests show that increasing the rear acoustic cavity volume by more than 50% can lower the low-frequency response to around 60Hz, thereby optimizing the low-frequency sound effect of the speaker 21.

[0061] Secondly, the electronic component 30 is also provided with a main circuit board 31, which is mounted on the top wall of the base component 10. Therefore, it is also necessary to open corresponding through holes on the main circuit board 31 so that the main circuit board 31 will not block the airflow.

[0062] like Figure 4 and Figure 7 As shown, preferably, a battery bracket 16 is provided at the opening on the top wall of the base component 10, which is used to support and fix the energy storage battery 17.

[0063] Specifically, since the energy storage battery 17 is installed inside the axial support 43, it is preferable to install a battery bracket 16 at the opening in the top wall to support and fix it. The battery bracket 16 has gaps between itself and the top wall of the base to prevent it from blocking the opening. For example, the battery bracket 16 can be designed with a perforated mesh structure, with its edges maintaining a gap of at least 5-10 mm between it and the inner wall of the opening in the top wall of the base to ensure smooth airflow.

[0064] To facilitate control and use of the entire device, a main switch 32, a connection button 33, a light button 34, a volume control knob 35, and a charging port 36, all electrically connected to the electronic components 30, can be installed on the side wall of the base component 10. The main switch 32 is used to switch the main power supply of the entire device on and off. The connection button 33 is used to activate the speaker's Bluetooth connection function, and a Bluetooth chip, as currently available in the technology, is installed on the main circuit board 31, enabling the speaker to connect to other devices, such as mobile phones and computers, via Bluetooth technology for sound playback. The light button 34 is used to control the light group 42 via the light control circuit, such as adjusting its brightness or lighting mode. The volume control knob 35 is used to control the speaker 21 via the sound control circuit, such as adjusting the volume. The charging port 36 is used to charge the energy storage battery 17.

[0065] In addition, in order to install the aforementioned switches, buttons, knobs or ports, corresponding openings need to be made in the solid sidewall 12. In order to achieve a sealing effect, a sealing structure (not shown in the figure) in the prior art needs to be set at the opening, such as a sealing ring or a sealing gasket, so that the opening of the solid sidewall 12 will not cause air leakage.

[0066] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
