Description

Technical Field

[0001] This utility model belongs to the field of baffle speaker technology, and more specifically, it relates to a floor-standing baffle speaker. Background Technology

[0002] A floorstanding baffle speaker is a special type of audio equipment. Its core feature is that the speaker units are directly mounted on a flat plate called a "baffle." The baffle's function is to prevent sound waves from the back of the speaker from reaching the front, thus avoiding interference with the front sound output and preventing sound quality degradation. This design allows the audio system to better utilize the speaker's performance, providing high-fidelity sound quality.

[0003] When traditional baffle speakers are combined with horn speakers, the low-frequency speakers in the baffle section and the mid-to-high-frequency horn speakers are out of phase. When sounds from different frequency bands are superimposed in space, the phase difference makes it impossible to achieve precise synchronization, resulting in a lack of smooth transition between frequency bands. For example, when playing music, there will be a disconnect between the low-frequency drum beats, the mid-frequency instrument sounds, and the high-frequency vocals. The sound will be disjointed, the playback quality will be poor, and it will be difficult to meet the current users' pursuit of high-quality audio.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention is a floor-standing baffle speaker, including a base, a fixing plate installed on the upper surface of the base, two bass horns set on the fixing plate, an mounting plate installed on the upper surface of the base, a shock-absorbing component set between the mounting plate and the base, a fixing frame and a fixing rod installed on the mounting plate, a mid-range horn installed at the upper end of the fixing frame and connected to the upper end of the fixing rod, a positioning frame installed on one side of the fixing frame, and a tweeter horn installed on the positioning frame;

[0006] The horn openings of the bass horn, midrange horn, and soprano horn are facing the same direction. There is a gap between the bass horn and midrange horn in the vertical plane, and the horizontal plane of the bass horn's horn opening is behind the horizontal plane of the midrange horn's horn opening. There is a gap between the soprano horn and bass horn in the vertical plane, and the horizontal plane of the soprano horn's horn opening is behind the horizontal plane of the bass horn's horn opening.

[0007] The distance between the horizontal plane of the bass horn opening and the horizontal plane of the midrange horn opening is 0.03m, and the distance between the horizontal plane of the tweeter horn opening and the horizontal plane of the midrange horn opening is 0.06m.

[0008] An acoustic grille is mounted on the mounting plate, covering the surface of the openings of the two bass horn speakers.

[0009] The positioning frame has a slot, through which the tweeter is set on the positioning frame, and the tweeter can slide and engage with the slot.

[0010] Vibration damping blocks are installed at the four corners of the lower surface of the base.

[0011] The shock absorber includes four point-contact damping feet. The upper surface of each point-contact damping foot is mounted on the lower surface of the mounting plate, and the lower end of each point-contact damping foot is mounted on the upper surface of the base.

[0012] The mounting bracket is connected to the upper part of the mounting plate by a belt.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, through the spatial arrangement of bass horn, midrange horn and treble horn, causes a delay in the propagation of different frequency bands, cleverly compensating for the original phase difference between each frequency band and achieving precise phase synchronization. When playing music or movie audio, low-frequency drum beats, mid-frequency instrument sounds and high-frequency vocals can be closely connected and naturally transitioned, avoiding sound disconnection and greatly improving the continuity and naturalness of sound quality. This brings users a more harmonious and realistic listening experience and significantly enhances the listening effect.

[0015] 2. This utility model can initially reduce vibration of the device through the shock-absorbing blocks, and further disperse and absorb vibration through the point contact shock-absorbing feet. In addition, the upper part of the fixing frame and the fixing plate are flexibly connected by a belt, which further reduces vibration transmission compared to a rigid connection. This shock absorption system can prevent resonance from forming inside the speaker, avoid sound distortion and sound quality degradation caused by resonance, and comprehensively ensure the stability of the speaker during operation, thereby improving the purity and clarity of the sound quality and optimizing the overall sound quality performance.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-7 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 7 As shown:

[0027] This embodiment provides a floor-standing baffle speaker, including a base 1, a fixing plate 2 installed on the upper surface of the base 1, two bass horns 3 vertically arranged on the fixing plate 2, a mounting plate 4 installed on the upper surface of the base 1, a shock absorber 5 between the mounting plate 4 and the base 1, a fixing frame 6 and a fixing rod 7 installed on the mounting plate 4, a midrange horn 8 installed on the upper end of the fixing frame 6 and connected to the upper end of the fixing rod 7, a positioning frame 9 installed on one side of the fixing frame 6, and a tweeter horn 10 installed on the positioning frame 9;

[0028] The horn openings of the bass horn 3, midrange horn 8, and tweeter horn 10 are facing the same direction. There is a gap between the bass horn 3 and midrange horn 8 in the vertical plane, and the horizontal plane of the horn opening of the bass horn 3 is located behind the horizontal plane of the horn opening of the midrange horn 8. There is a gap between the tweeter horn 10 and bass horn 3 in the vertical plane, and the horizontal plane of the horn opening of the tweeter horn 10 is located behind the horizontal plane of the horn opening of the bass horn 3.

[0029] In practical use, the base 1 provides basic support for this device, the fixing plate 2 is used to fix the bass horn 3, the fixing bracket 6 and the fixing rod 7 can fix the position of the midrange horn 8, the positioning bracket 9 is used to fix the midrange horn 8, and the shock-absorbing component 5 set between the mounting plate 4 and the base 1 can provide shock absorption and buffering for the midrange horn 8 and the treble horn 10.

[0030] When the audio equipment is powered on and receives an audio signal, such as Figure 7 As shown in the circuit diagram, the audio signal is transmitted to the corresponding drive unit of each horn. The drive unit of the bass horn 3 receives the low-frequency audio signal, converts the electrical signal into mechanical vibration, and pushes the air to generate low-frequency sound waves. Due to the structural design of the bass horn 3, the low-frequency sound waves are guided and amplified inside the horn, and then radiate out from the speaker opening. The drive unit of the mid-range horn 8 receives the mid-frequency audio signal, similarly converts the electrical signal into mechanical vibration, and generates mid-range sound waves. After being guided and amplified inside the mid-range horn 8, the mid-range sound waves radiate out from the speaker opening. The drive unit of the tweeter horn 10 receives the high-frequency audio signal, converts it into mechanical vibration, and generates high-frequency sound waves. After being guided and amplified inside the tweeter horn 10, the high-frequency sound waves radiate out from the speaker opening. Because the bass horn 3, mid-range horn 8, and tweeter horn 10... The speaker openings all face the same direction, ensuring that the sound of different frequency bands maintains consistency in the direction of propagation. Furthermore, by spacing the bass horn 3, treble horn 10, and midrange horn 8 in the vertical plane, and with the horizontal planes of the bass horn 3 and treble horn 10 located behind the midrange horn 8, the phase of the sound of different frequency bands is adjusted during propagation. This compensates for the original phase differences in low, mid, and high frequencies caused by distance differences when they reach the listener's location, achieving phase synchronization of different frequency bands. This device solves the problems of phase inconsistency and poor frequency band transitions in existing audio systems, enabling precise synchronous playback of all frequency bands, improving the continuity and naturalness of sound quality, and meeting the current user demand for high-quality audio.

[0031] like Figure 5 , Figure 6 As shown, the distance between the horizontal plane of the bass horn 3 and the horizontal plane of the midrange horn 8 is 0.03m, and the distance between the horizontal plane of the tweeter 10 and the horizontal plane of the midrange horn 8 is 0.06m. Audio analyzer testing revealed that the midrange horn 8 has the longest delay, followed by the bass horn 3, and the tweeter horn 10 has the shortest delay. (Reference) Figure 6 The test verification diagram shows that this installation method can achieve the required results, keeping the phases of the low, mid, and high frequency speakers consistent. This allows the device to optimize the phase difference between the various horns, achieving phase synchronization and ensuring that the sound reaches the listener's ears simultaneously, thus improving the sound quality.

[0032] like Figure 1 , Figure 2 As shown, an acoustic grille 11 is installed on the fixed plate 2. The acoustic grille 11 covers the surface of the openings of the two bass horn 3 speakers. By setting the acoustic grille 11 on the surface of the openings of the bass horn 3 speakers, the direct output of bass sound waves can be avoided, and the sound waves can be reflected and refracted on the surface of the acoustic grille 11. The phase of the bass sound waves is finely adjusted, and the sound quality of the bass is further optimized, making it fuller and richer.

[0033] like Figure 2 , Figure 4 As shown, the positioning frame 9 has a slot 12. The tweeter horn 10 is set on the positioning frame 9 through the slot 12, and the tweeter horn 10 can slide and engage with the slot 12. In actual use, users can install different tweeters horns 10 in various ways, and adjust the position of the tweeter horn 10 by sliding it in the slot 12 to ensure that the phase of the tweeter horn 10, the midrange horn 8, and the bass horn 3 remain the same, thus improving the adaptability of this device to the tweeter horn 10.

[0034] like Figure 3 As shown, vibration damping blocks 13 are provided at the four corners of the lower surface of the base 1; the damping component 5 includes four point-contact vibration damping feet 14. The upper surfaces of the point-contact vibration damping feet 14 are all installed on the lower surface of the mounting plate 4, and the lower ends of the point-contact vibration damping feet 14 are all installed on the upper surface of the base 1. The vibration damping blocks 13 can play a preliminary damping and buffering role, reducing the direct vibration transmission between the base 1 and the ground. Due to the point-contact design of the point-contact vibration damping feet 14, the contact area between the mounting plate 4 and the base 1 can be reduced to the greatest extent, thereby effectively reducing the vibration transmission efficiency. When the speaker vibrates, the point-contact vibration damping feet 14 can disperse and absorb the vibration, preventing the vibration from forming resonance inside the speaker, avoiding sound distortion and sound quality degradation caused by resonance. Thus, through this vibration damping system, the stability of the speaker during operation can be ensured, providing a solid foundation for the accurate propagation of sound, and further improving the purity and clarity of sound quality.

[0035] like Figure 1 , Figure 2 As shown, the mounting bracket 6 is connected to the upper end of the mounting plate 2 by a belt 15, which creates a flexible connection between the mid-high frequency structure and the low frequency structure. Compared with a rigid connection, this reduces the transmission of vibration, improves the shock absorption effect, and also ensures the stability of the mounting plate 2.

[0036] It should be noted that multiple units of this device can be connected and used simultaneously to create a wider sound field and improve the listening experience.

[0037] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
