Description

Technical Field

[0001] This utility model relates to the field of Bluetooth speaker structural design technology, and in particular to a waterproof Bluetooth speaker with airbag cushioning and sealing. Background Technology

[0002] A Bluetooth speaker is a portable electroacoustic device that establishes a wireless connection with an audio source device via the Bluetooth protocol, converting digital audio signals into sound waves. In daily life, to prevent liquids from entering the speaker's interior, a waterproof and insulating structure is usually required in the speaker's design.

[0003] Common liquid intrusion phenomena, such as beverage spills or rainwater seepage causing short circuits and sudden equipment damage, or the influence of humid environments such as bathroom steam or kitchen grease, can all lead to unstable operation of speaker components.

[0004] Currently, most Bluetooth speakers on the market use fixed sealing rings or gel filling structures to achieve waterproofing. However, after long-term use, the sealing material of such static sealing solutions is prone to aging, temperature changes, or mechanical deformation, which can cause gaps to form, allowing liquids (such as rainwater or beverages) to seep into the internal circuitry and cause short circuits. Especially in high-humidity environments such as bathrooms, steam penetration can accelerate component corrosion and reduce the lifespan of the device. Furthermore, traditional speakers rely on rigid protective layers to absorb drop impacts, but stress concentration in localized areas of the shell can easily cause cracks. In addition, the internal circuitry lacks buffer protection, and the impact force is directly transmitted to core components (such as Bluetooth modules and batteries), leading to broken solder joints or component displacement, resulting in a high rate of device damage.

[0005] To address this issue, a waterproof Bluetooth speaker with an airbag-cushioned seal was specially designed to solve the aforementioned technical problems. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a waterproof Bluetooth speaker with airbag cushioning and sealing.

[0007] The technical solution of this utility model is as follows: a waterproof Bluetooth speaker with airbag buffer sealing, comprising a shell, a buffer pad glued to the middle of the lower part of the shell, an isolation mesh cover for the external cover of the speaker module on the side of the shell, a Bluetooth module installed on the side of the middle of the shell near the speaker module, a sealing plate installed on the upper part of the shell, an airbag ring pad with a built-in air pump set on the inner wall of the shell ring, the airbag ring pad being a corrugated tube structure, with an air flow gap between the corrugated tube structure and the inner wall of the shell, a gap between the lower part of the airbag ring pad and the lower part of the shell, and a mounting cylinder movably mounted on the upper part of the buffer pad, the outer wall of the mounting cylinder having a groove suitable for the corrugated tube structure. Reinforcing base plates are provided on both sides of the bottom. The reinforcing base plates have cross-shaped reinforcing ribs in the middle. Multiple contact rods are symmetrically arranged on the upper part of the buffer pad. Each contact rod is surrounded by a spring. The lower part of the reinforcing base plate is slidably connected to each contact rod. The upper part of the reinforcing base plate is provided with rubber protrusions that slide in contact with the ends of the contact rods. A power storage module is installed on one side of the lower part of the mounting cylinder. The transmission wire of the power storage module extends upward and passes through the airbag ring pad and the inner wall of the mounting cylinder. The receiving end of the transmission wire also passes through the inner wall of the housing. An insulating sleeve is embedded in the side of the housing. The receiving end of the transmission wire is connected to the insulating sleeve. A protective cover is hinged to the outside of the insulating sleeve.

[0008] In one embodiment, the energy storage module is electrically interconnected with each power component.

[0009] In one embodiment, the lower part of the protective cover has a slot, and the end of the slot away from the insulating sleeve is shaped like a raised wedge.

[0010] In one embodiment, the device further includes a guide seat, a limiting member, a second spring, and a third spring. The guide seat is slidably disposed at the middle of the lower part of the insulating sleeve, and the limiting member is slidably disposed on the side of the guide seat. The upper part of the limiting member is provided with a hook portion, which matches the wedge-shaped portion of the protective cover and the two form an abutment. The sliding part between the guide seat and the insulating sleeve is provided with a second spring, and the sliding part between the limiting member and the guide seat is provided with a third spring.

[0011] In one embodiment, the device also includes a flow guide and a ramp. Flow guides are provided on the exterior of the heat dissipation vents on both sides of the lower part of the housing. The upper edge of the flow guide has a 30° chamfered design, and the lower part of the flow guide has an opening. A ramp is provided at the opening to prevent liquid from entering from an abnormal angle. A heat dissipation channel is left between the end of the ramp and the flow guide.

[0012] In one embodiment, an electric fan is also included, with the electric fan installed at the center of the lower part of the sealing cover.

[0013] In one embodiment, the device further includes a temperature and humidity monitor and a dryer. The temperature and humidity monitor is installed on one side of the lower part of the sealing plate, and the probe of the temperature and humidity monitor is exposed in the upper part of the sealing plate. The dryer is installed on the upper side of the mounting cylinder. The dryer and the electric fan are electrically connected to the temperature and humidity monitor.

[0014] Beneficial effects: 1. This utility model uses an air pump to inflate the airbag ring to form an annular airtight layer, which, combined with the elastic deformation of the corrugated pipe, prevents liquid intrusion and absorbs impact energy during a fall. The pressure is dispersed through air gaps to prevent the airbag from rupturing. The cross reinforcing ribs of the reinforced substrate, along with the contact rod, spring, and rubber protrusions, form a multi-level buffer system, effectively reducing the impact force on the internal components. The Bluetooth module and the audio module adopt a cavity isolation design to reduce acoustic vibration interference, improve signal transmission stability, and achieve the overall effects of waterproofing, drop resistance, and sound quality optimization.

[0015] 2. This utility model uses a temperature and humidity monitor to detect the internal environment in real time. When the temperature is too high, the electric fan will automatically accelerate to reduce the temperature rise of the components. When the humidity is too high, the dryer will start to absorb water vapor and discharge the moisture through the directional airflow of the guide shroud and the electric fan, thus avoiding condensation that could cause circuit corrosion.

[0016] 3. This utility model guides cold air into the air efficiently through the 30° inclined chamfer design of the air guide cover. The angle between the inclined plate and the heat dissipation channel prevents abnormal liquid splashing, ensuring that the heat dissipation efficiency is improved while maintaining waterproof performance.

[0027] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0028] Example: A waterproof Bluetooth speaker with airbag cushioning and sealing, such as Figures 1-5 , Figure 7 and Figure 8As shown, the device includes a housing 1, which serves as the main frame, providing installation space and physical protection for internal components. A buffer pad 101 is glued to the lower center of the housing 1 to absorb vibration and impact energy transmitted by the components, preventing damage to internal components due to vibration. An isolation mesh cover 2 is provided on the side of the housing 1 to cover the external part of the speaker module, preventing foreign objects from entering the speaker cavity while allowing sound waves to pass through. A Bluetooth module 21 is installed in the middle of the housing 1, near the speaker module. The Bluetooth module 21 is responsible for... The device receives wireless signals and decodes audio, establishing a Bluetooth connection with external devices. A sealing plate 3 is installed on the upper part of the housing 1, sealing the upper part of the housing 1 to prevent liquid intrusion from the top. An airbag ring 4 with a built-in air pump is installed on the inner wall of the housing 1. The airbag ring 4 has a corrugated tube structure, with an airflow gap between the corrugated tube structure and the inner wall of the housing 1. The lower part of the airbag ring 4 is spaced from the lower part of the inner wall of the housing 1. A mounting cylinder 5 is movably installed on the upper part of the buffer pad 101, serving as a mounting carrier for internal components. The outer wall of the mounting cylinder 5 has grooves suitable for a bellows structure to ensure sealing and cushioning effects. Reinforcing base plates 51 are provided on both sides of the bottom of the mounting cylinder 5. The reinforcing base plates 51 have cross-shaped, transversely distributed reinforcing ribs in their inner center. Multiple contact rods 52 are symmetrically arranged on the upper part of the buffer pad 101. A spring 53 is surrounding the outside of each contact rod 52. The lower part of the reinforcing base plate 51 is slidably connected to each contact rod 52, and the upper part of the reinforcing base plate 51 has rubber protrusions that slide in contact with the ends of the contact rods 52. A spring 53 is installed on one side of the lower part of the mounting cylinder 5. The device is equipped with a power storage module 6, which is electrically connected to all electrical components. The transmission wire 7 of the power storage module 6 extends upward and passes through the airbag ring pad 4 and the inner wall of the mounting cylinder 5. The receiving end of the transmission wire 7 also passes through the inner wall of the housing 1. An insulating sleeve 8 is embedded in the side of the housing 1. The insulating sleeve 8 serves as an insulating protective layer for the charging interface. The receiving end of the transmission wire 7 is connected to the insulating sleeve 8. A protective cover 9 is hinged to the outside of the insulating sleeve 8. A slot is opened at the bottom of the protective cover 9. The end of the slot away from the insulating sleeve 8 is shaped like a raised wedge.

[0029] like Figure 5 and Figure 9 As shown, it also includes a guide seat 10, a limiting member 11, a second spring 111, and a third spring 112. The guide seat 10 is slidably disposed at the lower middle part of the insulating sleeve 8, and the limiting member 11 is slidably disposed on the side of the guide seat 10. The guide seat 10 serves as a sliding base, and the limiting member 11 is driven to slide horizontally by longitudinal displacement to achieve the switching of the locking state of the protective cover 9. The upper part of the limiting member 11 is provided with a claw part, which matches the wedge-shaped part of the protective cover 9, and the two form an abutment to achieve locking and prevent the protective cover 9 from being accidentally opened by external force. The sliding part between the guide seat 10 and the insulating sleeve 8 is provided with a second spring 111, which provides longitudinal reset elastic force. The sliding part between the limiting member 11 and the guide seat 10 is provided with a third spring 112, which provides lateral reset elastic force.

[0030] like Figure 1 , Figure 2 and Figure 6 As shown, it also includes a flow guide shroud 12 and a ramp 13. Flow guide shroud 12 is provided on the outside of the heat dissipation vents on both sides of the lower part of the housing 1. The upper edge of the flow guide shroud 12 is designed with a 30° chamfer. The 30° chamfer design of the flow guide shroud 12 guides cold air into the bottom of the housing 1, improving heat dissipation efficiency. The lower part of the flow guide shroud 12 has an opening, and a ramp 13 is provided at the opening to prevent liquid from entering from an abnormal angle. A heat dissipation channel is left between the end of the ramp 13 and the flow guide shroud 12. The ramp 13 prevents liquid from splashing at an abnormal angle, while keeping the heat dissipation channel open. The ramp 13 and the flow guide shroud 12 are integrally formed or welded together.

[0031] like Figure 3 and Figure 7 As shown, it also includes an electric fan 14. The electric fan 14 is installed at the center of the lower part of the sealing cover by screws. The electric fan 14 accelerates the exhaust of internal hot air from the heat dissipation port under the housing 1, thereby enhancing the heat dissipation effect.

[0032] like Figure 3 and Figure 4 As shown, it also includes a temperature and humidity monitor 15 and a dryer 16. The temperature and humidity monitor 15 is installed on one side of the lower part of the sealing plate 3 by screws. The probe of the temperature and humidity monitor 15 is exposed in the upper part of the sealing plate 3. The dryer 16 is installed on the upper side of the mounting cylinder 5 by screws. The dryer 16 and the electric fan 14 are electrically connected to the temperature and humidity monitor 15. The temperature and humidity monitor 15 detects the internal environmental parameters in real time and triggers the electric fan 14 to accelerate or the dryer 16 to start. The dryer 16 absorbs water vapor and discharges it through the electric fan 14 to prevent condensation from corroding the circuit.

[0033] When the device starts, the airbag ring pad 4 is automatically inflated by the built-in air pump, causing the bellows to expand and fit against the inner wall of the housing 1, forming an annular sealing layer. At the same time, the space at the bottom of the airbag ring pad 4 allows gas to enter the bottom of the housing 1 through the airflow gap, balancing the internal and external air pressure and preventing heat dissipation obstruction due to excessive sealing. If the device is dropped, the airbag ring pad 4 will first compress and deform to absorb energy. The remaining impact force will be dispersed to the contact rod 52 through the reinforcing base plate 51 at the bottom of the mounting cylinder 5. The compression of spring 1 53 will further buffer the impact, and the sliding friction between the rubber protrusion and the contact rod 52 will generate damping, ultimately reducing the impact force to within the circuit safety threshold. When the protective cover 9 is closed, the hook part of the limiting member 11 will engage with the wedge groove of the protective cover 9. The tension of spring 3 112 will lock the hook, preventing the protective cover 9 from being accidentally opened due to external impact or liquid penetration, thus protecting the charging interface. When charging is required, the user presses the guide seat 10 upwards, and spring 2 111... When compressed, the guide seat 10 drives the limiting member 11 to slide horizontally away from the hook. At the same time, the restoring force of the spring 112 causes the limiting member 11 to return to its initial position. At this time, the protective cover 9 can be rotated around the hinge to open, exposing the charging interface. When the device is running, the device is wirelessly connected through the internal Bluetooth module 21. The electric fan 14 starts and draws the internal hot air out of the heat dissipation vent below the sealing plate 3. The external cold air enters the lower part of the housing 1 through the guide shroud 12. The inclined plate 13 of the guide shroud 12 forms an angle with the heat dissipation channel. If liquid (such as splashed water) splashes at an abnormal angle, the inclined plate 13 will bounce it out of the guide shroud 12. At the same time, the heat dissipation channel remains open to ensure that the air circulation is not affected. The temperature and humidity monitor 15 monitors the internal environment in real time. If the temperature is too high, the electric fan 14 accelerates. If the humidity is too high (such as bathroom steam), the dryer 16 starts to absorb water vapor and discharge it through the electric fan 14 and the heat dissipation vent.
