Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of audio equipment, and particularly relates to a moving iron unit array module and earphone based on progressive time difference simulation of reverberation. BACKGROUND

[0002] In the field of audio equipment, bass effect has always been a key element to improve the quality of sound experience. With the continuous pursuit of high-quality audio by people, moving iron units are widely used in audio equipment due to their high resolution and other advantages. However, traditional low-frequency moving iron units often have difficulty in creating an audio environment with a strong sense of space, and cannot meet the expectations of users for immersive audio enjoyment. The creation of a sense of space is of great importance to various audio application scenarios such as music and video, as it can make the listener feel as if they are in the real scene created by the audio, greatly improving the infectivity and expressiveness of the audio.

[0003] In existing audio equipment, low-frequency moving iron units are widely used due to their high resolution and fast response characteristics. However, there are still significant deficiencies in the presentation of spatial sense and reverberation effect. The specific problems are as follows.

[0004] Firstly, traditional low-frequency moving iron units usually adopt a design of connecting multiple sound outlets with sound guide pipes. This structure leads to relatively single sound wave divergence and propagation path, and the propagation path is relatively fixed. These units are difficult to reproduce the complex interaction of sound waves in a real environment. This is crucial for simulating sound wave reflection and scattering phenomena in a real environment, thus affecting the spatial sense and reverberation effect of the audio, making the audio experience lack the naturalness and depth in a real environment.

[0005] In addition, the digital signal processing (DSP) method used in existing audio equipment can usually only be used in active (i.e. requiring external power supply driving) systems. In addition, existing digital signal processing (DSP) technology is mainly suitable for active systems, i.e. devices that require external power supply driving. In contrast, passive earphones for professional use are limited in the direct application of DSP technology due to their pure passive structure, which makes it difficult for them to effectively improve the spatial sense and reverberation effect under existing technical conditions. UTILITY MODEL CONTENT

[0006] The purpose of the present application is to provide a moving iron unit array module and earphone based on progressive time difference simulation of reverberation, which solves the problem of poor effect in improving the spatial sense and reverberation effect of audio equipment in the prior art.

[0007] The purpose of the present application is achieved by the following technical solutions:

[0008] A moving iron unit array module based on progressive time difference simulation of reverberation, comprising a plurality of moving iron unit assemblies, and a progressive reverberation sound outlet assembly, wherein a sound channel and a sound outlet nozzle are arranged on the progressive reverberation sound outlet assembly, the sound channel is in communication with the sound outlet nozzle, and the plurality of moving iron unit assemblies are all connected to the sound channel, and each moving iron unit assembly has a different path length along the sound channel from the sound outlet nozzle.

[0009] Further, the moving iron unit assembly is a composite bass moving iron unit assembly.

[0010] Further, the plurality of moving iron unit assemblies are arranged in a polygonal stack.

[0011] Further, the progressive reverberation sound outlet assembly is a 3D printed structure.

[0012] Further, the progressive reverberation sound outlet assembly is provided with a sound channel and a sound outlet nozzle.

[0017] Further, the high-pitch moving iron unit assembly, the medium-pitch moving iron unit assembly, and the composite bass moving iron unit assembly are all double-unit structures.

[0018] The beneficial effects of the present application: the progressive reverberation sound outlet assembly designed in a polygonal structure significantly enhances the spatial sense of low-frequency sound effects. The progressive time delay produced by sound waves during propagation simulates the reflection and scattering in the natural environment, creating a more spacious and stereoscopic sound field.

DETAILED DESCRIPTION

[0026] The present application will be further described below in combination with specific embodiments and the accompanying drawings.

[0027] Embodiment 1

[0028] Reference Figure 1 and Figure 2 As shown in the figure, a moving iron unit array module based on progressive time difference simulation reverberation includes a plurality of moving iron unit assemblies and a progressive reverberation sound outlet assembly 7. Each moving iron unit has high resolution and fast response characteristics, ensuring accurate restoration and transmission of low frequency signals.

[0029] The progressive reverberation sound outlet assembly 7 is provided with a sound channel 701 and a sound outlet nozzle 702, the sound channel 701 communicates with the sound outlet nozzle 702, and the plurality of moving iron unit assemblies are all communicated to the sound channel 701, and each moving iron unit assembly has a different path length along the sound channel 701 from the sound outlet nozzle 702.

[0030] In order to optimize the production process of moving iron unit and improve its consistency, the traditional moving iron unit is removed and replaced with an integrated polygonal progressive reverberation sound outlet assembly 7. The assembly is manufactured by 3D printing technology, with the following structural characteristics: 1. The progressive reverberation sound outlet assembly 7 adopts a polygonal design, which is closely combined with the moving iron unit array to ensure effective synthesis and propagation of sound waves.

[0031] 2. The progressive reverberation sound outlet assembly 7 has only one sound channel 701 inside, and all moving iron units are connected to this sound channel through different length paths. By adjusting the path length of each moving iron unit to the sound outlet of the sound channel, the progressive time difference effect of sound waves is achieved.

[0032] The moving iron unit assembly is a composite bass moving iron unit assembly 6, which enhances the bass effect and improves the sound quality experience. Similarly, high and medium sound can also be enhanced in this form.

[0033] Several moving iron unit assemblies are arranged in a polygonal stack, matching the polygonal design of the progressive reverberation sound outlet assembly 7, ensuring uniform propagation of sound waves and optimization of spatial sense.

[0034] The progressive reverberation sound outlet assembly 7 is a 3D printed structure, which improves manufacturing precision and consistency, enhances modularity and customizability, and reduces production costs.

[0035] The progressive reverberation sound outlet assembly 7 is provided with a sound channel 701 and a sound outlet 702, and the sound outlet 702 is located at the end of the sound channel 701. All moving iron units are integrated on a sound channel 701 and a sound outlet 702, which is beneficial to structural design and effect presentation.

[0036] The path length of each moving iron unit to the sound outlet 702 is precisely calculated and designed. For example, the path length of the first moving iron unit to the sound outlet is L1, the path length increment is d1, the path length of the second moving iron unit is L1+d1, the path length of the third moving iron unit is L1+d1+d2, the path length of the fourth moving iron unit is L1+d1+d2+d3, the path length of the fifth moving iron unit is L1+d1+d2+d3+d4, the path length of the sixth moving iron unit is L1+d1+d2+d3+d4+d5, the path length of the seventh moving iron unit is L1+d1+d2+d3+d4+d5+d6, and the path length of the eighth moving iron unit is L1+d1+d2+d3+d4+d5+d6+d7. According to the required time difference effect, audio characteristics and other factors, the path length difference is precisely designed through a large number of acoustic experiments and theoretical calculations, so that each moving iron unit produces a progressive time difference to simulate the bass reverberation effect.

[0037] Due to the different path lengths of each moving iron unit to the sound outlet, the sound waves emitted from different units will produce a gradual time difference, simulate the multiple reflection and scattering effects of sound waves in the natural environment, form a reverberation effect, and enhance the spatial sense and stereo sense of the audio.

[0038] Embodiment 2

[0039] Reference Figures 1-5 As shown in the figure, a headphone based on progressive time difference simulation of reverberation includes a headphone shell 1 and a headphone cover body 2, and a headphone cavity 3 is formed between the headphone shell 1 and the headphone cover body 2. The moving iron unit array module of embodiment 1 is arranged in the headphone cavity 3.

[0040] The headphone cavity 3 is provided with a high-pitched moving iron unit assembly 4, a medium-pitched moving iron unit assembly 5, and a composite low-pitched moving iron unit assembly 6, and the sound outlets of all moving iron unit assemblies are opposite to the sound outlet of the headphone shell 1.

[0041] The moving iron unit assembly of embodiment 1 is the composite low-pitched moving iron unit assembly 6.

[0042] The high-pitched moving iron unit assembly 4 and the medium-pitched moving iron unit assembly 5 are both provided with two, the composite low-pitched moving iron unit assembly 6 is provided with eight, and the high-pitched moving iron unit assembly 4, the medium-pitched moving iron unit assembly 5, and the composite low-pitched moving iron unit assembly 6 are all double-unit structures.

[0043] In a 24-unit moving iron headphone, there are eight composite low-pitched moving iron unit assemblies 6, two composite medium-pitched moving iron unit assemblies 5, and two composite high-pitched moving iron unit assemblies 4. For the eight composite low-pitched moving iron unit assemblies 6, their respective sound outlets are removed, and then the progressive reverberation sound outlet assembly 7 manufactured by 3D printing technology is installed, ensuring that each moving iron unit is connected to the sound outlet 702 through a path of different length.

[0044] During the transmission of the audio signal, the eight composite low-pitched moving iron unit assemblies 6 simultaneously receive the signal and emit sound through the shared sound outlet. Due to the difference in path length, a progressive time difference is produced, resulting in a progressive time delay, simulating the reflection and scattering of sound waves in the natural environment and thus simulating the low-pitched reverberation effect. At the same time, the two composite medium-pitched moving iron unit assemblies and the two composite high-pitched moving iron unit assemblies work normally, respectively outputting the medium and high-pitched audio, and cooperating with the low-pitched part to ultimately create a rich and full audio experience with a strong sense of space for the user.

[0045] The foregoing basic examples and each further selected example of the present application can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed by the present application. In the present application scheme, each selected example can be arbitrarily combined with any basic example and selected example.

[0046] The above only describes preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
