Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a dual 10-inch active two-way compression loudspeaker. Background Art

[0002] Small sound reinforcement venues are facing increasingly stringent requirements for speakers, demanding both a compact size to complement the aesthetics of the interior and high sound pressure levels. Consequently, dual 10-inch point-source speakers are becoming increasingly popular. However, most dual 10-inch speakers currently on the market utilize a planar waveguide structure. While this structure is simple and requires minimal technical expertise, it also has significant drawbacks. Planar waveguides struggle to effectively boost the sound pressure level of the speaker, failing to meet the stringent sound quality requirements of small sound reinforcement venues.

[0029] See also Figure 1-Figure 4The present invention discloses a dual 10-inch active two-way compression speaker, including a box body 1, in which a low-frequency component 2 and a high-frequency component 3 are arranged. The low-frequency component 2 is symmetrically arranged on the upper and lower sides of the high-frequency component 3, and the low-frequency components 2 are tilted toward the high-frequency component 3 respectively, and a low-frequency guide channel 22 is formed between the low-frequency component 2 and the high-frequency component 3.

[0030] The low-frequency component 2 is symmetrically tilted toward the high-frequency component 3, which greatly reduces the longitudinal size of the loudspeaker, and the tilted symmetrical low-frequency component 2 forms a large horn diffusion booster, so that the loudspeaker can exert greater low-frequency energy; the setting of the low-frequency guide channel 22 is conducive to superimposing low-frequency sounds and improving the quality and effect of the bass; the setting of the low-frequency component 2 and the high-frequency component 3 helps to enhance the propagation of sound and energy concentration, improves the quality and effect of sound, effectively improves the sound pressure level of the loudspeaker, meets the high requirements of small sound reinforcement venues for sound effects, and overcomes the problem of insufficient sound pressure level of existing planar waveguide structures.

[0031] See also Figure 1 The high-frequency component 3 includes a high-frequency driver and a high-frequency diffuser 32. The high-frequency driver is rotatably connected to the sound input end of the high-frequency diffuser 32. Through the rotational connection, the relative position of the high-frequency driver and the high-frequency diffuser 32 can be adjusted within a certain range, thereby adjusting the propagation direction of the high-frequency sound to better meet different sound reinforcement requirements.

[0032] See also Figure 3 The diffusion end of the high-frequency diffuser 32 is provided with a diffusion plate 33. The setting of the diffusion plate 33 enhances the diffusion ability of the high-frequency diffuser 32, so that the high-frequency sound is spread more evenly, the coverage is wider, and the sound is clearer and more accurate.

[0033] The high-frequency driver is a 1.5-inch throat diameter, 75mm voice coil compression driver, and the high-frequency diffuser 32 is a 60-degree x 50-degree constant directivity high-frequency diffuser 32. The specific specifications of the high-frequency driver and high-frequency diffuser 32 ensure stable high-frequency acoustic performance, providing high-frequency sound output that matches the overall speaker design, ensuring sound quality and accuracy.

[0034] See also Figure 1 as well as Figure 2The low-frequency component 2 includes two 10-inch woofers 21, which are located on the upper and lower sides of the high-frequency diffuser 32, and are symmetrically tilted toward the high-frequency diffuser 32. Specifically, two mounting plates 11 are provided within the cabinet 1 for securing and mounting the 10-inch woofers 21, with the two 10-inch woofers 21 mounted on different mounting plates 11. The symmetrical tilting of the two 10-inch woofers 21 toward the high-frequency diffuser 32 helps form a more efficient low-frequency energy propagation structure, improve the low-frequency sound pressure level, and enhance the effect of the low-frequency sound.

[0035] The angle between the two 10-inch woofers 21 is 140 degrees. The two 10-inch woofers 21 are symmetrically installed in the cabinet 1 at a 140-degree angle, which can stably form a large horn diffusion and boosting effect, effectively enhancing and diffusing low-frequency energy, and improving the quality and loudness of low-frequency sound.

[0036] See also Figure 1 The high-frequency diffuser 32 has its diffusion end located in front of the diffusion end of the 10-inch woofer 21. The low-frequency guide channel 22 is the space between the diffusion end of the 10-inch woofer 21 and the sidewall of the high-frequency diffuser 32. The low-frequency guide channel 22 facilitates better superposition of low-frequency sounds, further optimizing the propagation of low-frequency sounds and improving bass quality.

[0037] See also Figure 4 The cabinet 1 is also equipped with a two-channel digital power amplifier module 4 and a two-way digital audio processor 5 for processing audio signals and controlling the timbre. Specifically, the two-channel digital power amplifier module 4 and the two-way digital audio processor 5 are both located on the side of the cabinet 1 away from the high-frequency component 3. When in use, the audio signal first enters the two-channel digital power amplifier module 4 for amplification and preliminary processing. The two-way digital audio processor 5 then controls the timbre, adjusting the audio signal's frequency response, balance, dynamic range and other parameters to achieve the best timbre effect.

[0038] See also Figure 4 A hanging hole 6 is provided on one side of the cabinet 1. Specifically, two hanging holes 6 are provided on one side of the cabinet 1, one at the top and one at the bottom of the two-channel digital power amplifier module 4. These hanging holes 6 facilitate hanging installation of the speaker, improving installation convenience and flexibility and adapting to various installation environments.

[0039] See also Figure 2 , carrying holes 7 are opened on opposite sides of the box body 1. Specifically, the side walls of the box body 1 at both ends along the length direction are opened with carrying holes 7. The provision of the carrying holes 7 facilitates the carrying operation of personnel, makes the movement of the speaker more convenient and quick, and improves the convenience during use.

[0040] The implementation principle of this embodiment is as follows:

[0041] When a dual 10-inch active two-way compression speaker is in operation, the audio signal is first input to the two-channel digital amplifier module 4 within the cabinet 1. The two-channel digital amplifier module 4 amplifies and performs preliminary signal processing based on the characteristics of the input signal. After being processed by the two-channel digital amplifier module 4, the audio signal is transmitted to the two-way digital audio processor 5. The two-way digital audio processor 5 begins to fine-tune the timbre. After the audio signal undergoes this processing, it is distributed to the low-frequency component 2 and the high-frequency component 3.

[0042] For the low-frequency component 2, since the two 10-inch woofers 21 are symmetrical and tilted at an angle of 140 degrees on the upper and lower sides of the high-frequency diffuser 32, when the low-frequency part of the audio signal drives the woofer to make a sound, the tilted structure allows the low-frequency sound to propagate at a specific angle and in a specific manner. The large horn diffusion and boosting effect formed by this layout allows the energy of the low-frequency sound to be effectively concentrated and enhanced during the propagation process. At the same time, the low-frequency sound propagates in the low-frequency guide channel 22 (the space between the diffusion end of the 10-inch woofer 21 and the side wall of the high-frequency diffuser 32). This channel promotes the superposition of low-frequency sound, further enhancing the energy and effect of the low-frequency sound, so that the low-frequency sound can be propagated at a larger sound pressure level in a small sound reinforcement venue, and maintain good sound quality, meeting the venue's requirements for low-frequency effects.

[0043] After the high-frequency component 3 receives the high-frequency portion of the processed audio signal, the high-frequency driver generates high-frequency vibrations, driving the high-frequency diffuser 32 to work. Since the high-frequency driver is rotatably connected to the sound input end of the high-frequency diffuser 32, the relative positions of the two can be adjusted during installation or according to the requirements of different sound reinforcement scenarios, thereby changing the propagation direction of the high-frequency sound. When the high-frequency sound propagates to the diffusion end of the high-frequency diffuser 32, the diffusion plate 33 will further scatter the high-frequency sound, making the high-frequency sound propagate more evenly and covering a wider range. This uniform propagation method allows high-frequency sound to accurately reach every corner in small sound reinforcement venues, and the sound is clear and accurate, avoiding the auditory imbalance caused by the sound being concentrated in certain areas.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
