Description

Technical Field

[0001] The utility model belongs to the technical field of sounders, and in particular relates to a high-sound-level sounder. Background Art

[0002] A sound generator is a device that can convert electrical signals into sound. It is commonly used in various electronic devices, such as mobile phones, computers, electronic toys, alarm systems, etc. The basic principle of a sound generator is to generate vibrations through electronic circuits. These vibrations are transmitted through the air and are eventually captured by the human ear to form sounds. There are two main working principles of sound generators: one is based on the electromagnetic principle of speakers, and the other is based on the vibration principle of buzzers. Speakers use the magnetic effect generated when a changing current passes through a coil to vibrate the paper cone (or metal film) connected to the coil, thereby producing sound. A buzzer is usually a metal column with an electromagnet. When current passes through the electromagnet, it vibrates and produces sound. In modern electronic devices, sound generators are not limited to making simple sounds, but can also produce complex sound patterns, including music, human voices, and various other sound effects. In addition, with the development of technology, the size of sound generators has become smaller and smaller, but the sound quality and volume have been significantly improved.

[0003] Existing sound generators, especially high-sound-level sound generators, often have excessively high temperatures because the vibrations generated by the sound are converted into heat energy, which in turn causes thermal deformation of some of their internal structures, affecting the sound quality. Therefore, there is an urgent need for a device that can effectively cool the interior of a high-sound-level sound generator. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] Reference Figures 1 to 3 The utility model provides a high-sound-level sounder, comprising: a sounder housing 1, one side of the sounder housing 1 is open, a sounding structure 2 is fixedly connected to the opening of the sounder housing 1, one end of the sounding structure 2 close to the inner side of the sounder housing 1 is fixedly connected to a circuit board 3, and the sounding structure 2 is electrically connected to the circuit board 3;

[0029] A heat transfer wire 4 is wound around the outside of the sound-generating structure 2 , a heat sink 5 is fixedly connected to the outside of the sound generator housing 1 , two ends of the heat transfer wire 4 are fixedly connected to the heat sink 5 , and the heat sink 5 is electrically connected to the circuit board 3 .

[0030] A heat transfer wire 4 is provided in the present device to absorb the heat on the outside of the sound-generating structure 2 and transfer it to the heat sink 5 for dissipation. The heat sink 5 can also effectively cool the outside of the sound generator housing 1, so that the sound-generating structure 2 in the present device is maintained in a stable and low temperature range, thereby protecting the normal operation of the sound-generating structure 2 in the present device.

[0031] The air flow in the sound generator housing 1 transfers heat. Due to the poor thermal conductivity of air, the heat generated by the sound-generating structure 2 is difficult to discharge. The heat transfer wire 4 in the present application can directly contact the sound-generating structure 2 for heat transfer, and dissipate heat through the material with good thermal conductivity. While achieving waterproof and moisture-proof properties to improve the sound quality, it can ensure that the sound-generating structure 2 is effectively cooled.

[0032] The device utilizes these structures to realize a high-sound-level sounder that can effectively cool the sound-generating structure 2, thereby solving the overheating problem that often exists in high-sound-level sounders.

[0033] According to a further optimized solution, the sound-generating structure 2 includes a basin frame 203, the basin frame 203 is fixedly connected to the inner side of the sound generator housing 1, and the heat transfer wire 4 is wound around the outer side of the basin frame 203;

[0034] One end of the basin frame 203 close to the inner side of the sound generator housing 1 is fixedly connected to a magnetic steel 204, a T-iron 205 is provided inside the magnetic steel 204, and one end of the T-iron 205 away from the basin frame 203 is fixedly connected to one end of a support rod 206, and the other end of the support rod 206 is fixedly connected to the circuit board 3;

[0035] A speaker 202 is fixedly connected to the side of the basin frame 203 away from the sound generator housing 1, and a gap is left between the speaker 202 and the basin frame 203;

[0036] The magnet 204 , the speaker 202 and the circuit board 3 are electrically connected.

[0037] The structural setting of the sound-generating structure 2 is a conventional technical means in the field and will not be elaborated here.

[0038] According to a further optimized solution, a dust cover 201 is provided at one end of the speaker 202 away from the basin frame 203 , and the dust cover 201 is fixedly connected to the sound generator housing 1 .

[0041] The contact electronic thermometer 6 can measure the temperature of the outside of the sounder housing 1 in real time. When the temperature of the outside of the sounder housing 1 is too high and exceeds a threshold, it indicates that the heat sink 5 is faulty or the speaker 202 generates too much heat. At this time, a power-off operation is triggered to prevent the speaker 202 from being damaged.

[0042] In a further optimized solution, the heat sink 5 is a semiconductor cooling sheet, and the cooling end of the heat sink 5 faces the sound generator housing 1. The semiconductor cooling sheet is divided into a cooling surface and a heating surface. In this device, the surface temperature of the semiconductor cooling sheet can be well reduced by facing the cooling end of the semiconductor cooling sheet toward the sound generator housing 1, while the heating surface faces the outside to ensure that the heat can be taken away in time.

[0043] According to a further optimized solution, a bracket 7 is fixedly connected to the inner bottom surface of the sound generator housing 1 , and the circuit board 3 is fixedly connected to the top surface of the bracket 7 .

[0044] According to a further optimized solution, two jacks 101 are provided on one side of the sound generator housing 1 , the circuit board 3 is electrically connected to the external signal source through one jack 101 , and the circuit board 3 is electrically connected to the external power source through the other jack 101 .

[0045] The two jacks 101 are both electrically connected to the circuit board 3 through wires for transmitting sound signals and electricity.

[0047] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
