Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a loudspeaker with an adjustable unit. Background Art

[0002] Speakers are a very common electroacoustic transducer device found in all sound-producing electronic and electrical devices. With the continuous advancement of digital signal processing (DSP) technology, audio signal processing capabilities are becoming increasingly powerful. DSP can analyze, adjust, and optimize input audio signals in real time. For example, using a fast Fourier transform (FFT) to convert an audio signal from the time domain to the frequency domain, it analyzes the intensity and phase information of different frequency components. Based on this information, it can enhance, attenuate, or adjust the phase of specific frequency ranges as needed.

[0003] During use, it is necessary to adjust the sound played by the speaker, such as changing the sound propagation characteristics so that the sound can be propagated farther or wider. During the adjustment process, the existing speakers can only adjust the diameter of the outer cover to adjust the volume of the sound, but cannot adjust the length of the outer cover to adjust the sound. Utility Model Content

[0004] The purpose of the present invention is to provide a loudspeaker with an adjustable unit to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A speaker with an adjustable unit includes a speaker body and a horn-shaped outer cover tube, the speaker body is provided with a mounting ring, the mounting ring is provided with a length adjustment piece, the length adjustment piece and the speaker body are slidably engaged, the length adjustment piece and the mounting ring are slidably engaged, the outer cover tube is detachably connected to the length adjustment piece, the outer cover tube is provided with an extension cover tube, and the extension cover tube and the outer cover tube are slidably engaged.

[0007] A further technical solution is that the length adjustment part includes an inner ring tube, an outer ring tube, two sliding frames and two sliders, the inner ring tube is arranged in the outer ring tube, the outer ring tube and the mounting ring are slidably fitted, the two sliding frames are symmetrically arranged on both sides of the outer ring tube, the two sliders are symmetrically arranged on both sides of the speaker body, the sliding frame is provided with a sliding groove, the slider slides in the sliding groove, and the slider is provided with two threaded locking screws, and the two locking screws are diagonally arranged.

[0008] According to a further technical solution, four limit blocks are provided on the inner ring cylinder, and a limit groove that slides with the limit blocks is provided on the mounting ring.

[0009] A further technical solution is that two sliding blocks are respectively provided on the outer wall of the outer cover tube, and a sliding groove for sliding cooperation of the sliding blocks is provided in the extended cover tube, one of the sliding blocks is provided with a plurality of threaded holes arranged at equal intervals, and the extended cover tube is provided with a locking screw threadedly connected to it, and the locking screw is threadedly connected to the threaded hole.

[0010] According to a further technical solution, four plug-in blocks are provided at the bottom of the outer cover tube, and four plug-in slots are provided on the inner ring tube.

[0011] According to a further technical solution, a sealing rubber ring is provided on the outer cover tube, and the extension cover tube slides on the sealing rubber ring.

[0012] Beneficial effects of the utility model:

[0013] During use, the utility model can drive the position of the outer cover tube to extend and slide horizontally through the length adjustment member, thereby increasing the path for sound propagation. By extending the cover tube and sliding it on the outer cover tube, the diameter of the outer cover tube can be expanded. When the diameter of the trumpet-shaped outer cover becomes larger or the length is lengthened, the directionality of the speaker will be more obvious. The trumpet outer cover with a larger diameter and longer length can make the sound propagate more concentratedly in a specific direction. Low-frequency sound has a longer wavelength and requires a larger space to radiate effectively. Increasing the diameter of the trumpet-shaped outer cover or lengthening its length can provide a more suitable radiation environment for low-frequency sound waves. From the perspective of acoustic resonance, the appropriate outer cover size can resonate with low-frequency sound waves and enhance the output of low-frequency sound. This allows the sound to propagate over a wider range and with better effects.

[0014] Other features and advantages of the present invention will be described in detail in the subsequent detailed description of the embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] Please refer to Figure 1-6 As shown; the utility model provides a technical solution for a speaker with an adjustable unit: a speaker with an adjustable unit, comprising a speaker body 1 and a horn-shaped outer cover tube 4, the speaker body 1 is provided with a mounting ring 10, the mounting ring 10 is provided with a length adjustment member 2, the length adjustment member 2 and the speaker body 1 are slidably matched, the length adjustment member 2 and the mounting ring 10 are slidably matched, the outer cover tube 4 is detachably connected to the length adjustment member 2, the outer cover tube 4 is provided with an extension cover tube 3, the extension cover tube 3 and the outer cover tube 4 are slidably matched.

[0024] During use, the outer cover tube 4 can be extended and slid horizontally by the length adjustment member 2. The outer cover tube 4 can be expanded by sliding the extension tube 3 on the outer cover tube 4. When the diameter of the trumpet-shaped outer cover becomes larger or the length is lengthened, the directionality of the speaker will be more obvious. The outer cover tube 4 with a larger diameter and longer length can make the sound propagate more concentratedly in a specific direction. Low-frequency sound has a longer wavelength and requires a larger space to radiate effectively. Increasing the diameter of the trumpet-shaped outer cover or lengthening its length can provide a more suitable radiation environment for low-frequency sound waves. From the perspective of acoustic resonance, the appropriate outer cover size can resonate with low-frequency sound waves and enhance the output of low-frequency sound. This makes the sound propagation wider and more effective.

[0025] In this embodiment, referring to Figure 3 、 Figure 4 and Figure 5As shown, the length adjustment member 2 includes an inner ring tube 21, an outer ring tube 22, two sliding frames 23 and two sliders 24. The inner ring tube 21 is arranged in the outer ring tube 22. The outer ring tube 22 and the mounting ring 10 are slidably matched. The two sliding frames 23 are symmetrically arranged on both sides of the outer ring tube 22. The two sliders 24 are symmetrically arranged on both sides of the speaker body 1. The sliding frame 23 is provided with a sliding groove 25. The sliders 24 slide in the sliding groove 25. The sliders 24 are provided with two threaded locking screws 26. The two locking screws 26 are arranged diagonally. The inner ring tube 21 is provided with four limit blocks 27. The mounting ring 10 is provided with a limit groove 11 that slides with the limit blocks 27. When the limit blocks 27 slide in the limit groove 11, they can ensure that the position of the outer ring tube 22 is limited during the movement process, and deflection and rotation will not occur, which will affect the propagation of sound.

[0026] When the length of the outer cover tube 4 is lengthened, the corresponding locking screw 26 on the slider 24 is loosened, so that the outer ring tube 22 moves in the two sliders 24 through the two end grooves 25 on the two sliding frames 23, so that the outer ring tube 22 slides on the mounting ring 10 and separates the outer ring tube 22 from the mounting ring 10. When the slider 24 and the groove 25 collide with each other, it means that the maximum distance between the outer ring tube 22 and the mounting ring 10 is reached. The corresponding locking screw 26 is rotated and tightened so that the slider 24 is locked in the groove 25 and will not move. At this time, there is no gap between the mounting ring 10 and the outer ring tube 22. After the sound propagation path is lengthened, the internal reflection path of the sound will change, so that more sound energy can be transmitted along the axial direction of the outer cover tube 4, reducing scattering in other directions.

[0027] In this embodiment, referring to Figure 6 As shown, two sliding blocks 41 are respectively provided on the outer wall of the outer cover tube 4, and a sliding groove 31 for sliding cooperation of the sliding blocks 41 is provided in the extended cover tube 3, wherein one of the sliding blocks 41 is provided with a plurality of threaded holes 42 arranged at equal intervals, and the extended cover tube 3 is provided with a locking screw 43 threadedly connected thereto, and the locking screw 43 is threadedly connected to the threaded hole 42.

[0028] When the diameter of the outer cover tube 4 is expanded, the locking screw 43 can be loosened to allow the extended cover tube 3 to slide on the outer cover tube 4, so that the extended cover tube 3 is extended and overlapped on the outer cover tube 4, which will increase the diameter of the outer cover tube 4. After the position is determined, the locking screw 43 is rotated to fix the extended cover tube 3 on the outer cover tube 4 without moving its position. When the diameter of the outer cover tube 4 becomes larger, the sound generated by the speaker body 1 can improve the sound propagation characteristics, improve the acoustic efficiency and meet different design requirements.

[0029] In this embodiment, referring to Figure 6 As shown, four plug-in blocks 44 are provided at the bottom of the outer cover tube 4, and four plug-in grooves 28 are provided on the inner ring tube 21. The plug-in blocks 44 are plugged into the plug-in grooves 28, and the plug-in blocks 44 are provided with screws 29 connected to the inner ring tube 21.

[0030] During the process of installing and disassembling the outer cover tube 4 , the plug-in block 44 can be removed from the plug-in slot 28 by simply loosening the screw 29 , or the plug-in block 44 can be installed in the plug-in slot 28 by tightening the screw 29 .

[0031] In this embodiment, a sealing rubber ring is provided on the outer housing tube 4, and the extension housing tube 3 slides on the sealing rubber ring. The provision of the sealing rubber ring can fill the gap between the outer housing tube 4 and the extension housing tube 3, preventing sound from escaping from the gap between the two, causing a dispersion effect on sound propagation and affecting sound transmission.
