Abstract

This utility model relates to a special sound field structure inside a speaker enclosure, including a speaker housing and a base snapped into the inside of the speaker housing. Several support legs are installed below the base for mounting and support. At least four resonant blocks are arranged on the inner wall of the speaker housing, and a positioning post is provided between two adjacent resonant blocks. The positioning post is fixedly installed on the top and side of the inner wall of the speaker housing. Several positioning posts are installed on the upper surface inside the base, the number of which is the same as the number of positioning posts. This special sound field structure utilizes the sound wave reflection and diffusion characteristics of a circular or conical shape inside the speaker enclosure. A raised semi-circular fan-shaped microcavity resonant structure design is added inside the circular or conical speaker enclosure, so that the same sound waves inside the speaker enclosure do not form a booster field requiring attenuation, but instead increase the effect of multiple resonance diffusion reverberation caused by reflection in different directions.

Description

Technical Field

[0001] This utility model relates to the field of sound field and sound effect technology, specifically to a special structure for the sound field inside a speaker. Background Technology

[0002] A speaker, also known as a sound transducer, is mainly used for playing sound.

[0003] Most speaker enclosures use circular, square, or conical designs. However, traditional sound waves of the same frequency will cancel or superimpose. Different structures are also important acoustic phenomena that affect the reflection and diffusion of sound waves and thus the sound effect. Since the internal structure of existing speakers has not undergone specialized acoustic field testing and design, it seriously affects the auditory effect of the speakers and even the effect of sound wave therapy.

[0004] Therefore, a special sound field structure inside the speaker is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a special sound field structure inside a speaker that can solve problems such as wavelength cancellation or superposition.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a speaker housing and a base snapped into the inside of the speaker housing, wherein a plurality of support legs for mounting are installed below the base;

[0007] The inner wall of the speaker housing is provided with at least four resonant blocks, and a positioning post is provided between two adjacent resonant blocks. The positioning post is fixedly installed on the top and side of the inner wall of the speaker housing.

[0008] The upper surface inside the base is equipped with several positioning posts II, the number of which is the same as that of positioning posts I, and a cavity block is provided between two adjacent positioning posts I.

[0009] Preferably, the speaker housing is a combination of circular and conical shapes, and the upper end of the speaker housing has several through holes.

[0010] Preferably, the resonant block is a raised semi-circular fan shape, and the arc length of the resonant block on the side near the speaker housing is greater than the length of the resonant block on the side near the through hole, and the resonant blocks are evenly distributed in a ring on the arc-shaped surface of the inner wall of the base.

[0011] Preferably, the resonant block and the inner wall of the base form a resonant space for the speaker housing, which is used to improve the orderly reflection of sound waves.

[0012] Preferably, a sound wave generator is placed at one-third of the height of the interior of the base, and the sound wave generator is placed in a pyramid-like height ratio.

[0013] Preferably, the cavity block is in the shape of a raised arc fan, and the cavity block corresponds to the position of the resonant block. The cavity block and the interior of the base are combined to form a reflective vibration diaphragm cavity, which is used to enhance the frequency of sound waves.

[0014] Compared with the prior art, this utility model provides a special sound field structure inside the speaker, which has the following beneficial effects:

[0015] 1. The speaker has a special sound field structure. It utilizes the sound wave reflection and diffusion characteristics of the internal ring or cone shape. The speaker has added a raised semi-circular fan-shaped microcavity resonance structure design inside the circular or conical speaker. This design prevents the same sound waves inside the speaker from forming a booster field that needs to be reduced. Instead, it increases the effect of multiple resonance diffusion reverberation by reflecting in different directions.

[0016] 2. The speaker has a special sound field structure. The sound transducer (i.e., speaker) is installed according to the height ratio of a pyramid. This allows the sound waves to be transmitted and diffused vertically, achieving the best auditory and therapeutic effects through delay and hysteresis mixing.

[0017] 3. The speaker has a special sound field structure. By designing a high-resilience vibrating diaphragm cavity resonance at the bottom of the speaker, when the reverse sound wave from the upper speaker is transmitted to the lower vibrating diaphragm cavity, the lower vibrating diaphragm cavity forms a secondary same-frequency diaphragm cavity vibration, and the delayed sound wave is formed, thereby achieving the effect of enhancing the diffuse reverberation hearing and the healing effect of multiple vibrations.

[0018] 4. The speaker has a special sound field structure, which is connected by positioning post one and positioning post two, improving the stability of the structure. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0026] Please see Figure 1 - Figure 4 In this embodiment, a special sound field structure inside a speaker includes a speaker housing 1 and a base 2 that is snapped into the inside of the speaker housing 1. Several support legs 3 for mounting and support are installed below the base 2.

[0027] The inner wall of the speaker housing 1 is provided with at least four resonant blocks 4, and a positioning post 5 is provided between two adjacent resonant blocks 4. The positioning post 5 is fixedly installed on the top and side of the inner wall of the speaker housing 1.

[0028] Several positioning posts 8 are installed on the upper surface of the base 2. The number of positioning posts 8 is the same as that of positioning posts 5. A cavity block 7 is provided between two adjacent positioning posts 5.

[0029] First, insert and fix the speaker housing 1 to the base 2. Then, using the outer bolts, with the combination of positioning post 1 5 and positioning post 2 8, firmly secure the speaker housing 1 and the base 2 for use.

[0030] By combining multiple cavity blocks 7 inside the speaker housing 1, the device is provided with sound wave reflection support from the bottom. By combining multiple resonant blocks 4 inside the base 2, the device is provided with orderly sound wave reflection support from the side. Thus, when the speaker housing 1 and the base 2 are used together, the device has the effect of simultaneous reflection from the side and the bottom, so that the sound waves inside the device are reflected and diffused, improving the frequency and clarity of the sound wave reflection inside the device, and ensuring the effect of the device.

[0031] The resonant block 4 is a raised semi-circular fan shape, and the arc length of the resonant block 4 on the side near the speaker housing 1 is greater than the length of the resonant block 4 on the side near the through hole. The resonant block 4 is evenly distributed in a ring on the arc surface of the inner wall of the base 2.

[0032] The resonant block 4 and the inner wall of the base 2 form a resonant space for the speaker housing, which is used to improve the orderly reflection of sound waves.

[0033] By setting the resonant block 4 as a raised semi-circular fan shape, the positive and negative sound waves inside the speaker will not form a booster field. The sound waves of the same frequency in different directions cancel each other out and attenuate to form a disordered sound wave. This special structural design allows the sound field inside the speaker to be superimposed and enhanced to utilize multiple orderly reflections, and enhances the audio vibration transmission effect of external diffusion and reverberation. By setting the inner side of the upper end of the speaker housing 1 as a ring-shaped stepped structure, the propagation path of the sound waves inside the speaker can be changed, so that the sound is reflected and scattered multiple times in the cavity. The stepped surfaces at different angles allow the sound waves to interfere with and superimpose each other, enriching the sound details, creating a more three-dimensional sound field effect, and improving the layering and spatial sense of the sound quality. The symmetrical distribution of several arc-shaped cone blocks allows the sound waves to be continuously reflected inside the speaker housing 1 to achieve the effect of sound enhancement.

[0034] The speaker housing 1 is a combination of circular and conical shapes, and several through holes are passed through the upper end of the speaker housing 1;

[0035] By adopting a circular and conical design for the speaker housing 1, and simultaneously enhancing the sound wave reflectivity and diffusion inside the device, compared to the traditional circular or square design, and with some designs featuring a conical shape, the combination of circular and conical shapes better conforms to acoustic propagation characteristics. Furthermore, the propagation effect of the device is guaranteed by the flow support of multiple through holes.

[0036] A sound wave generator is placed at one-third of the height of the interior of the base 2, and the sound wave generator is placed in a pyramid-shaped height ratio.

[0037] By designing the sound wave generator (i.e. the speaker) to be placed at one-third of the height of the speaker housing 1 in a pyramidal proportion, the diffusion, reflection and reverberation effects of the sound waves inside the speaker are enhanced by utilizing the difference in sound wave conduction distance and delay.

[0038] The cavity block 7 is in the shape of a raised arc fan, and the cavity block 7 corresponds to the position of the resonant block 4. The cavity block 7 and the interior of the base 2 are combined to form a reflective vibration diaphragm cavity, which is used to enhance the frequency of sound waves.

[0039] By combining the cavity block 7 with the base 2, a reflective vibration diaphragm cavity is formed inside the base 2. The resonance of the diaphragm cavity further enhances the output of multiple sound wave frequencies, thereby improving the sound playback effect.

[0040] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0041] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
