Description

Technical Field

[0001] This utility model relates to the field of portable alarm device technology, specifically to a small sound-emitting structure with lighting function. Background Technology

[0002] In outdoor activities (such as hiking, camping, and night running) or special work environments (such as construction sites and mines), rapid warnings in emergency situations are crucial.

[0003] Traditional alarm devices are limited in function, relying solely on sound or light, making it difficult to effectively transmit warning signals in complex environments. For example, existing technology discloses a Chinese utility model, such as CN216927772U, entitled "Emergency Alarm for Personal Self-Defense," which specifically discloses an alarm body and an alarm pin mounted on the alarm body. The alarm pin is movably connected to the alarm body and is partially inserted / removed via limiting structures respectively provided on both. These limiting structures include a limiting block on the alarm body and a limiting groove on the alarm pin that cooperates with the limiting block to achieve limiting. The emergency alarm for personal self-defense provided in this application eliminates the need to reset the alarm pin back to the alarm body, allowing users to quickly reset the alarm.

[0004] In life, we inevitably encounter some emergencies. Therefore, the functionality and portability of alarm devices are crucial. Although the above-mentioned devices can emit alarm sounds, if the environment has poor lighting and is in a very open space, the alarm sound alone will not serve a good alarm function. The overall functionality is poor and the alarm function is limited.

[0005] Therefore, a small sound-generating structure with lighting function is proposed to solve the above-mentioned problems. Utility Model Content

[0039] The present invention will be further described below with reference to the embodiments.

[0040] Example 1:

[0041] See appendix Figure 1-9 This case proposes a small sound-generating structure with lighting function, including a shell 1 with a regular hexahedral structure, about 8cm on each side, made of high-strength ABS plastic, which is waterproof and drop-proof. The shape of the shell 1 is not specifically limited, and it can be held in the hand or carried on the body during normal use.

[0042] An illumination panel 10 and a sound-emitting element 11 are provided on the outer end face of the housing 1. In this embodiment, the illumination panel 10 adopts an LED panel light structure. A lighting switch 13 for controlling the opening and closing of the lighting module is provided on one side of the housing body of the housing 1. The illumination panel 10 is opened and closed by pressing the lighting switch 13.

[0043] It can be used not only as a regular lighting device, but also emits sound and light when in poor lighting conditions and open spaces.

[0044] In this embodiment, a circuit board 2 is provided inside the housing 1. The circuit board 2 integrates at least a sound-generating module electrically connected to the lighting panel 10 and a lighting module electrically connected to the sound-generating element 11.

[0045] In addition, a lithium battery storage unit is provided inside the housing 1, which is electrically connected to the circuit board 2 and is used to supply power to the lighting panel 10 and the sound-generating component 11. A charging hole is provided on one end face of the housing 1, and the lithium battery storage unit is charged by an external power source.

[0046] It should be noted that a removable waterproof plug is installed inside the charging port. One side of the waterproof plug is fixed to the housing 1. During normal use, the waterproof plug is inserted into the charging port to prevent water from entering the internal components.

[0047] It is worth noting that in this embodiment, the lighting panel 10 and the sound-emitting element 11 are distributed on two opposite outer end faces of the housing 1, that is, the orientation of the lighting panel 10 and the sound-emitting element 11 can be determined by rotating the housing 1 as needed.

[0048] The housing 1 is also provided with a plug-in switch 12 for controlling the opening and closing of the sound module. When danger is encountered, the plug-in switch 12 can be pulled to start the sound module, thereby making the sound-emitting component 11 emit a loud sound to warn.

[0049] To facilitate tearing and prevent accidental activation, the plug-in switch 12 is installed at any of the apexes of the housing 1.

[0050] In this embodiment, the sound-generating component 11 includes a vibrating ceramic sound-generating structure 111 and a sound-amplifying structure 113. The vibrating ceramic sound-generating structure 111 includes a piezoelectric ceramic sheet 112. The principle of vibration sound generation is well-known technology and will not be elaborated here. In this embodiment, a vibration motor is integrated on the circuit board 2 to strike the piezoelectric ceramic sheet 112 at high speed to generate sound. The vibration of the piezoelectric ceramic sheet 112 generates high-frequency sound waves, which are reflected and amplified by the "labyrinth structure" formed by the sound guide hole 1133 and the sound guide ring (see...). Figure 5-9 It outputs a sound pressure level of 110dB and has a coverage range of 50 meters.

[0051] In order to make the sound more powerful and louder, the piezoelectric ceramic sheet 112 is flat and parallel to the front and rear end faces of the housing 1, while the sound amplification structure 113 is disposed between the piezoelectric ceramic sheet 112 and the outer end face of the housing 1.

[0052] It should be noted that the sound amplification structure 113 includes a first sound amplification structure 1131 and a second sound amplification structure 1132. The first sound amplification structure 1131 has a sound guide hole 1133 in the middle. The sound emitted from the piezoelectric ceramic sheet 112 will be emitted through the sound guide hole 1133, and one end of the first sound amplification structure 1131 is positioned directly opposite the piezoelectric ceramic sheet 112.

[0053] At the other end of the first sound amplification structure 1131, there are two first sound guide rings 1134 that are concentrically distributed with the sound guide hole 1133 and have different heights. The second sound amplification structure 1132 is disposed between the first sound amplification structure 1131 and the outer end face of the housing 1. The end of the second sound amplification structure 1132 facing the first sound amplification structure 1131 is provided with a second sound guide ring 1135. The second sound guide ring 1135 and the two first sound guide rings 1134 are concentrically distributed and staggered. Thus, the "maze structure" formed by the two first sound guide rings 1134 and the second sound guide ring 1135 will cause the sound to reflect multiple times, making the sound more robust.

[0054] The end of the second sound reinforcement structure 1132 away from the first sound reinforcement structure 1131 is arc-shaped, and the housing 1 has multiple sound-permeable holes 14 at the end of the arc-shaped surface of the second sound reinforcement structure 1132, through which sound is emitted, ensuring uniform sound diffusion.

[0055] Example 2:

[0056] Based on Embodiment 1 above, this embodiment proposes the following scenarios for applying the device in Embodiment 1.

[0057] For example, outdoor nighttime emergency lighting and alarms: when hikers get lost at night, they need to illuminate the path and send out a distress signal at the same time. First, press the lighting switch 13 to turn on the LED light panel to provide continuous lighting (lasting about 6 hours). In an emergency, unplug the plug switch 12 to trigger the sound module, and the device will continuously emit a high-frequency alarm sound to attract the attention of rescuers.

[0058] For example, it can serve as a safety warning on construction sites. When workers are working in confined spaces, they need to quickly warn of sudden dangers (such as collapses). First, fix the device to the safety helmet or tool bag. The lighting panel 10 faces forward to provide local lighting. In case of danger, pull the plug switch 12 to activate the sound and light simultaneously, transmitting a warning signal through the noise environment.

[0059] Another application is in personal self-defense. When a woman is walking alone at night, she can carry the device as a self-defense tool. It can also be used as a flashlight (lighting mode) during daily walks. When threatened, she can quickly unplug and plug in switch 12 to trigger a high-decibel alarm, deterring attackers and attracting the attention of passersby.

[0060] The product in this embodiment not only provides dual-mode sound and light warnings to adapt to complex environmental needs, but also boasts a compact overall structure (weighing only 150g), is waterproof and drop-proof, and suitable for extreme outdoor conditions. Furthermore, the optimized sound wave propagation (maze structure) through the sound guide ring effectively enhances the warning range and clarity.

[0061] In addition, this product uses a rechargeable lithium battery, which supports 6 hours of continuous lighting or 8 hours of intermittent alarm, meeting the needs of long-term use.

[0062] It solves the problems of traditional alarm devices having limited functionality and poor environmental adaptability. It has significant practical value in outdoor emergency response, industrial safety and personal protection. Its sound and light coordinated design, portable operation and reliable performance make it an efficient and multifunctional warning tool in emergency situations.

[0063] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
