Through the arrangement of the loudspeaker main body and the sound amplification main body, the sound amplification main body is in threaded connection with the end part of the loudspeaker main body, and the loudspeaker main body firstly performs first-layer amplification on sound to ensure that the sound can be effectively transmitted. And then, the sound amplified by the loudspeaker main body is amplified again through the appearance design of the sound amplification main body, and is transmitted out through the sound amplification hole in the side part of the sound amplification main body. Compared with a circular hole, the rhombic hole can better enhance the sound effect in some frequency ranges. Due to the fact that the shape and the structure of the rhombic hole can disperse sound waves more effectively and reduce reflection and interference of the waves, clearer and fuller sound effect performance can be achieved within a specific frequency range.

Description

Technical Field

[0001] The utility model relates to the technical field of speakers, in particular to a long-range horn speaker. Background Technique

[0002] A long-range horn speaker is a device for audio propagation, mainly used in occasions such as broadcasting, signal transmission, and alarms. Its design aims to improve the sound propagation distance and clarity, and is suitable for various environments, including outdoor activities, sports events, emergency drills, etc. This kind of speaker usually adopts a horn-shaped structure, which can effectively focus sound waves and concentrate the sound wave energy to the maximum extent in a specific direction, thereby enhancing the sound propagation ability. Compared with traditional speakers, the long-range horn speaker has a higher sound pressure level and a longer propagation distance, and is suitable for use in noisy or vast environments. The sound quality of the long-range horn speaker is usually affected by materials and design. High-quality speakers use durable materials, such as plastic, aluminum, or wood, which can provide clear and loud sounds and adapt to various outdoor conditions. In addition, according to needs, this kind of speaker can be connected to different types of audio devices, such as power amplifiers, wireless microphones, etc., to further expand its application range. In emergency management, the long-range horn speaker can be used as part of an alarm system to help send alarm or prompt messages in case of emergencies. Its long-distance communication ability makes it an important communication tool in critical moments.

[0003] Currently, in case of emergencies, the sound propagation distance of ordinary speakers is relatively short, and it may not be able to cover a vast area or a distant crowd. This may lead to the information not being conveyed to everyone in time, especially when the crowd is dispersed or far away from the speaker; therefore, it does not meet the existing needs, and for this reason, we propose a long-range horn speaker.

Please refer to Figures 1-5, A long-range horn speaker, including a speaker main body 110, an amplification main body 111 is detachably installed at the end of the speaker main body 110, an amplification head 112 is arranged inside the speaker main body 110, and a number of amplification sound transmission balls 113 are installed inside the amplification main body 111. The amplification head 112 and the amplification sound transmission balls 113 are used in cooperation.

[0024] The inner wall of the speaker main body 110 is set as a threaded wall, a threaded head 114 is connected to the end of the amplification main body 111, the threaded head 114 is in threaded cooperation with the inner wall of the speaker main body 110, an amplification hole 115 is opened at the end of the amplification sound transmission ball 113, and a number of amplification holes 115 are provided. The number of amplification holes 115 are distributed on the surface of the amplification sound transmission ball 113.

[0025] The amplification hole 115 is set as a diamond-shaped hole. An installation plate 120 is connected to the side of the speaker main body 110, a clamping component 130 is installed on the side of the installation plate 120, a first handle 141 is connected to the bottom of the speaker main body 110, and a second handle 142 is connected to the bottom of the amplification main body 111.

[0026] In this embodiment: Through the settings of the speaker main body 110 and the amplification main body 111, the amplification main body 111 is threadedly connected to the end of the speaker main body 110. The speaker main body 110 first expands the sound for the first layer to ensure the effective transmission of the sound. Then, the external shape design of the amplification main body 111 amplifies the sound expanded by the speaker main body 110 again and transmits it through the amplification holes 115 on its side. Compared with circular holes, diamond-shaped holes can better enhance the sound effect in certain frequency ranges. This is because the shape and structure of the diamond-shaped holes can more effectively disperse sound waves, reduce wave reflection and interference, so as to achieve a clearer and fuller sound effect performance in a specific frequency range, solving the problem that in case of an emergency, the sound transmission distance of ordinary speakers is relatively short, and may not be able to cover a vast area or a distant crowd. This may result in the information not being conveyed to everyone in time, especially in the case where the crowd is dispersed or far from the speaker.

[0027] Embodiment 2, the purpose of this embodiment is to promote the solution of the problem that the sound wave is affected by the loosening of the thread. This embodiment is an improvement made on the basis of Embodiment 1. Specifically, please refer to Figures 1-5 , The clamping component 130 includes a pressing plate 131 and a clamping column 132. The pressing plate 131 is rotatably connected to the side of the installation plate 120 by a rotating shaft 133. A spring main body 134 is connected between the pressing plate 131 and the side of the speaker main body 110. A first notch 135 is opened on the side of the threaded head 114, and a second notch 140 is opened on the side of the speaker main body 110. The first notch 135, the second notch 140, and the clamping column 132 are jointly clamped inside the first notch 135 and the second notch 140.

[0028] In this embodiment: Through the setting of the clamping component 130, the horn body 110 is matched with the threaded head 114. While performing threaded connection, the pressing plate 131 is pressed, and the pressing plate 131 unlocks the clamping post 132. When the threaded connection is completed, the pressing plate 131 is released, and the clamping post 132 is engaged with the first notch 135 and the second notch 140. This not only simplifies the installation process but also ensures the stable connection of the device, avoiding sound distortion or propagation interruption caused by loose threads. The detachable setting enables the horn after disassembly to be used as an ordinary horn, and the range of the horn body 110 after installation can be longer.
