Description

Technical Field

[0001] This utility model relates to the field of acoustic equipment technology, and in particular to a sound amplification device. Background Technology

[0002] Ceramic materials, due to their high hardness and excellent acoustic properties, are used in audio equipment to improve sound quality. However, current technologies utilize the resonance characteristics of ceramic materials in a relatively basic way, failing to combine them with dual-channel designs to achieve higher quality sound effects. For example, patent CN108052224B discloses an interactive interface device that selectively excites and receives planar asymmetric sound waves, employing a mono or simple acoustic cavity design, which cannot meet users' needs for stereo and surround sound effects.

[0003] A ceramic speaker enclosure is a device that uses ceramic material as the main body of the speaker, characterized by its attractive appearance, low cost, and ease of production. Due to the high hardness of ceramic material, its enclosure design and volume, when matched with the low-frequency unit, can effectively improve low-frequency response. For example, the ceramic speaker disclosed in patent CN2535991Y focuses on a mono design, making it difficult to achieve stereo effects, and it does not fully utilize the resonance characteristics of ceramic material, resulting in a weak sense of spatial sound.

[0004] The hollow ceramic player solves the problems of large dimensional errors and vibration by using hollow ceramic as the sound cavity of the player base and connecting it with rubber pads, thus giving full play to the advantages of ceramic materials. For example, patent CN203588690U discloses a hollow ceramic player, which has made a breakthrough in sound cavity design, but does not involve the design of dual-channel amplification, and cannot meet users' needs for surround sound effects.

[0005] Two-channel power amplifiers are widely used in the audio field. They achieve stereo effects through two independent channel outputs, significantly improving the spatial sense and positioning of sound. Existing two-channel technology focuses more on electronic circuit design and does not take into account the acoustic properties of specific materials (such as ceramics), thus failing to further enhance the naturalness and resonance of the sound. For related discussion and analysis, please refer to "Stereo (Two-Channel) Power Amplifiers".

[0006] In summary, existing technologies do not fully utilize the resonance characteristics of ceramic materials and fail to fully combine the acoustic properties of ceramic materials with dual-channel design; most existing ceramic speakers and amplification equipment are mono designs and cannot achieve stereo effects; surround sound effects are lacking, and existing equipment is unable to provide high-quality spatial sense and sound positioning effects; the combination of materials and technology is insufficient, and the acoustic potential of ceramic materials has not been effectively combined with modern dual-channel power amplifier technology.

[0007] In view of this, this utility model is proposed. Utility Model Content

[0008] This invention addresses the problems in existing technologies, such as the inability of mono designs to achieve stereo effects, insufficient utilization of the resonance characteristics of ceramic materials, and inadequate spatial sense and sound positioning effects of audio equipment. It proposes a sound amplification device that, through reasonable structural design and material selection, fully utilizes the acoustic properties of ceramic materials to achieve efficient sound amplification and stereo surround sound effects.

[0009] This utility model provides a sound amplification device, including: a ceramic resonating cavity, on which an electronic product placement part and a sound output part are provided, an annular shunt channel is formed inside the ceramic resonating cavity between the electronic product placement part and the sound output part, and a channel correction part is provided inside the annular shunt channel near the sound output part.

[0010] Preferably, the ceramic resonator is made of black pottery or unglazed glazed tiles, which are low-cost materials with simple production processes and low manufacturing costs, giving them high market competitiveness. In addition, other ceramic materials with good acoustic properties can be used, such as high-density porcelain or special ceramics. Industrial byproducts such as coal gangue and porcelain powder can be introduced into the material formulation to further optimize the material's acoustic performance.

[0011] Optionally, the annular split channel can be adjusted to other structures with good resonance effects, such as spiral or multi-segment designs, depending on actual needs.

[0012] Preferably, the ceramic resonator includes an upper ceramic resonator structure and a lower ceramic resonator structure that are fastened together; both the upper and lower ceramic resonator structures have notches on the same side, and when they are fastened together, a sound output section is formed at the notch position; the upper ceramic resonator structure has an electronic product placement section on the opposite side of the notch.

[0013] Preferably, the upper structure and lower structure of the ceramic resonator can be connected by embedding, snap-fit, or thread, which makes disassembly and assembly convenient, operation simple, and maintenance easy, making it suitable for different user groups.

[0014] In this invention, the opening shape of the sound output section can be annular, elliptical, polygonal, etc., to adapt to different audio requirements.

[0015] Preferably, the upper structure of the ceramic resonator is a shell with a concave center and a circumferential protrusion around the perimeter, and the lower structure of the ceramic resonator is a shell with a protrusion at the center and a circumferential concave perimeter.

[0016] Preferably, there are two channel correction sections, which are located at the two ends of the annular split channel, respectively.

[0017] Preferably, the channel correction part is made of rubber and is a spherical cavity structure with through openings at both ends. The excellent sound absorption and insulation properties of rubber absorb noise and reduce low-frequency resonance interference. It also reduces sound wave reflection interference in different directions and guides sound waves to propagate in a specific direction (limiting the sound wave diffusion range), thereby making the sound between channels clearer.

[0018] When amplification equipment is working, resonance interference (low-frequency noise) that does not enhance sound may occur between some structures. The channel correction unit optimizes the amplification effect by absorbing the noise generated by low-frequency resonance. Furthermore, the part of the amplification equipment near the electronic product placement area will resonate as a whole during amplification resonance. The channel correction unit is designed as an isolation channel for the channels. It is fixedly placed in the amplification equipment and can accurately divide the channels to optimize the sound wave propagation path. It can effectively reduce crosstalk between the left and right channels and enhance the distinction between the left and right channels.

[0019] Preferably, the electronic product placement section is provided with sound amplification ports on both sides.

[0020] Preferably, the electronic product placement part includes a vertical slot and a horizontal slot that fit together, the horizontal slot being formed at the top of the upper structure of the ceramic resonant cavity, and the vertical slot being formed at the bottom of the horizontal slot.

[0021] Preferably, the amplification port is located on both sides of the horizontal slot.

[0022] Preferably, the edges of the vertical and horizontal grooves are provided with silicone anti-slip pads.

[0023] Optionally, the connection between electronic products and amplification equipment can be via Bluetooth wireless connection or other forms of audio interface to accommodate different types of devices.

[0024] Preferably, the bottom of the ceramic resonator is connected to a base.

[0025] This utility model has at least the following beneficial effects:

[0026] (1) Improved sound quality: By utilizing the excellent resonance characteristics of ceramic materials, the low-frequency and mid-frequency performance of the sound is significantly enhanced, making the sound quality fuller, richer and clearer.

[0027] (2) Significant stereo effect: Through the ring-shaped split channel, the audio signals of the left and right channels are independently propagated, enhancing the spatial sense and positioning effect of the sound, and providing a real stereo surround experience.

[0028] (3) No power support, energy saving and environmental protection: No power is required. It relies on sound wave resonance amplification to reduce energy consumption, which is in line with the concept of green environmental protection.

[0029] (4) Highly convenient and widely compatible: The electronic product placement section supports physical connection, easy insertion operation, stable and reliable during use, avoiding the impact of vibration or displacement on sound quality, and is suitable for a variety of electronic products.

[0030] In summary, this utility model is superior to the existing technology in terms of sound quality, stereo effect, energy saving and environmental protection, and ease of operation, and has significant technical, economic and social value. Attached Figure Description

[0041] Example

[0042] like Figure 1 As shown, this embodiment provides a sound amplification device, including: a ceramic resonating cavity, on which an electronic product placement part and a sound output part 6 are disposed, and an annular shunt channel 4 is formed inside the ceramic resonating cavity between the electronic product placement part and the sound output part 6, with an inner diameter of 80mm and an outer diameter of 300mm; and a channel correction part 7 is disposed inside the annular shunt channel 4 near the sound output part 6.

[0043] The ceramic resonator utilizes the resonant properties of ceramic materials to enhance the low-frequency and mid-frequency performance of the sound, making the sound fuller and richer. The electronic product placement section connects electronic products to the amplification equipment, ensuring that audio can be efficiently transmitted to the ceramic resonator. The annular split channel 4 enables independent propagation of left and right channel signals, avoiding sound mixing and improving the stereo effect. The sound output section 6 enhances the sound diffusion performance, realizing a dual-channel output mode, so that the sound is evenly distributed in the space, improving the sense of space and positioning effect.

[0044] In this embodiment, the surface of the annular split channel 4 is polished to reduce resistance during sound propagation, thereby improving the clarity and stereo effect of the sound, and realizing sound splitting and enhancement.

[0045] like Figure 3 As shown, in this embodiment, the ceramic resonator includes an upper ceramic resonator structure 1 and a lower ceramic resonator structure 3 that are tightly assembled together by a snap-fit ​​structure; both the upper ceramic resonator structure 1 and the lower ceramic resonator structure 3 have notches on the same side, and when they are snapped together, a cavity is formed at the notch position, which is the sound output part 6; the upper ceramic resonator structure 1 has an electronic product placement part on the opposite side of the notch.

[0046] In this embodiment, the upper structure 1 of the ceramic resonator cavity is a shell with a concave center and a ring-shaped protrusion around the perimeter, and the lower structure 3 of the ceramic resonator cavity is a shell with a protrusion at the center and a ring-shaped concave perimeter around the perimeter.

[0047] In this embodiment, there are two channel correction units 7, which are located at both ends of the annular split channel 4.

[0048] like Figure 5 As shown, in this embodiment, the channel correction part 7 is made of rubber and is a spherical cavity structure with through-holes at both ends. One through-hole is used to gather the audio generated by resonance, and the other through-hole faces the sound output part 6. The inner diameter of the channel correction part 7 is larger than the inner diameter of the ceramic resonance cavity, so that the channel correction part 7 can be better fixed in the ceramic resonance cavity.

[0049] In this embodiment, the electronic product placement section is provided with horn-shaped dual-channel audio amplification ports 22 on both sides for preliminary audio amplification.

[0050] like Figure 4 As shown, in this embodiment, the electronic product placement part includes a semi-enclosed vertical groove 20 and a horizontal groove 21. The horizontal groove 21 is fixed to the top of the upper structure 1 of the ceramic resonator cavity by an adhesive, and the vertical groove 20 is opened at the bottom of the horizontal groove 21.

[0051] In this embodiment, the dual-channel audio amplification ports 22 are located on both sides of the horizontal slot 21 and connected to the side openings of the horizontal slot (21). The shape and size design of the vertical slot 20 and the horizontal slot 21 are preferably designed to accommodate common mobile phone models placed vertically / horizontally. Preferably, the vertical slot 20 is rectangular in shape, with dimensions of 100mm × 16mm and a depth of approximately 110mm, which can accommodate common mobile phone models placed vertically; the horizontal slot 21 is rectangular in shape, with dimensions of 160mm × 24mm and a depth of approximately 80mm, which can accommodate common mobile phone models placed horizontally.

[0052] In this embodiment, 1mm thick silicone anti-slip pads are attached to the edges of the vertical groove 20 and the horizontal groove 21 to protect the surface of the electronic product and improve the stability of its placement.

[0053] like Figure 2 As shown, in this embodiment, a base 5 is connected to the bottom of the ceramic resonator. The base 5 is connected to the ceramic resonator by an adhesive, or it can be designed magnetically for easy disassembly and cleaning. The base 5 is located at the bottom of the lower structure 3 of the ceramic resonator to support the entire amplifier and ensure its stable placement. The base 5 is made of rubber, with a ring-shaped structure, an inner diameter of 150mm, an outer diameter of 155mm, and a thickness of 2mm, to enhance anti-slip performance and prevent the amplifier from moving due to vibration or external force during use, while also providing a better user experience.

[0054] The working process of this utility model:

[0055] In practical use, when a user places their mobile phone on the upper structure 1 of the ceramic resonance cavity through the vertical slot 20 or the horizontal slot 21, and starts playing audio, the sound emitted by the phone's speaker will enter the interior of the ceramic resonance cavity. After entering the annular distribution channel 4, the sound is split into the left and right channels and amplified by the resonance of the ceramic material. The sound is then collected and corrected by the channel correction unit 7 before being emitted through the sound output unit 6 via the left and right channels, achieving a stereo sound effect. The entire device is reasonably designed, easy to assemble, and highly stable during use. At the same time, the resonance characteristics of the ceramic material effectively improve the sound quality and propagation effect.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
