Technical Field
[0001] This utility model relates to the field of headphone device technology, and in particular to a sound guiding structure and its headphone device. Background Technology
[0002] With continuous breakthroughs in electronic product technology and the fast-paced changes in living environments, people's functional demands for headphones are constantly increasing. Most headphones have a resonant acoustic cavity located inside the earpiece. The sound waves generated by the speaker resonate within this cavity. Different materials and structures of the acoustic cavity result in different timbres. Timbre refers to the perceived characteristics of sound. The pitch of a sound source depends on the frequency of its vibration, and the loudness depends on the amplitude of its vibration. However, different sound sources, due to their different materials and structures, produce different timbres. Improving the timbre of headphones primarily depends on the acoustic cavity design. Therefore, to enhance the timbre of headphones, a good acoustic cavity is needed, and further optimization is required based on the acoustic characteristics of the structure. The design should consider structural vibration and sound issues early in the structural design process, and a dynamic acoustic design should be completed to meet the requirements for low vibration and low noise, thereby improving the listening comfort of the headphones. Existing headphone devices can only distinguish and process high, mid, and low frequency audio data and input them into the sound guide structure through different mid-range drivers. This lack of flexibility in adjusting and setting the sound according to specific usage environments and user needs limits the tuning flexibility of the headphone device. Furthermore, existing sound guide structures are inconvenient to install and affect the sound mixing effect. Utility Model Content
[0003] To address the aforementioned issues, the present invention aims to provide a sound guiding structure and its earphone device, enabling audio data of different frequencies to be flexibly transmitted to the human ear through the corresponding sound guiding structure, thereby improving the compatibility and structural stability of the earphone device and enhancing the user experience.
[0004] The technical solution adopted by this utility model to solve its problem is:
[0005] In a first aspect, this application provides a sound guiding structure, comprising: a main body, an audio unit, and a sound guiding cavity; the sound guiding cavity is located within the main body, one end of the sound guiding cavity is provided with a plurality of sound inlets, and the other end of the sound guiding cavity is provided with a sound outlet; the sound inlets include a first sound inlet, a second sound inlet, a third sound inlet, a fourth sound inlet, a fifth sound inlet, and a sixth sound inlet; a first reflective surface is provided between the first sound inlet and the sound outlet, a second reflective surface is provided between the second sound inlet and the sound outlet, and a third reflective surface is provided between the third and fourth sound inlets and the sound outlet, and a fifth sound inlet... A sound transmission block is provided between the sound inlet and the sixth sound inlet and the sound outlet; the inner wall of the sound guide cavity is provided with a groove for fixing the sound outlet; the audio unit includes a high-frequency moving iron unit, a mid-high-frequency moving iron unit, a mid-frequency moving iron unit, a mid-low-frequency moving iron unit, and a low-frequency moving iron unit; the high-frequency moving iron unit is connected to the first sound inlet and the second sound inlet, the mid-high-frequency moving iron unit is connected to the third sound inlet, the mid-frequency moving iron unit is connected to the fourth sound inlet, the mid-low-frequency moving iron unit is connected to the fifth sound inlet, and the low-frequency moving iron unit is connected to the sixth sound inlet.
[0006] The aforementioned sound guiding structure has at least the following beneficial effects: by setting up audio units and sound guiding cavities, different audio units can be connected to sound outlets through different sound inlets as needed, improving the compatibility and adjustment flexibility of the sound guiding structure; by setting up sound guiding cavities and sound outlets, the sound entering the main body through the sound inlet can be propagated to different reflective surfaces within the sound guiding cavity, simulating different reflection processes and improving the user experience of the sound guiding structure; since the sound outlet is stably connected through grooves, displacement of the main body during use is avoided, thus improving the structural stability of the sound guiding structure.

This structure ensures that the audio units are stably and evenly distributed on both sides of the main body, preventing the corresponding sound inlets of the audio units from being too close together and affecting the sound guiding effect of the sound guiding structure.
[0008] Furthermore, the shape of the second reflective surface corresponds to the cymba conchae; the shape of the third reflective surface corresponds to the cavum conchae. This structure ensures that the high-frequency balanced armature unit and the second sound inlet can simulate the process of high-frequency sound waves entering the ear canal after being reflected by the auricle, achieving a high-frequency transparency effect; it also ensures that the mid-to-high frequency balanced armature unit and the third sound inlet can simulate the process of mid-to-high frequency sound waves entering the ear canal after being reflected by the auricle, achieving a high-frequency smoothness effect.
[0009] Furthermore, the shape of the first reflective surface corresponds to the antihelix. This structure ensures that the first sound inlet and the first reflective surface simulate the process of high-frequency sound waves entering the ear canal after being reflected by the auricle, achieving a high-frequency transparency effect.
[0010] Furthermore, a damping element for filtering sharp peaks is provided between the sound inlet and the audio unit. By setting the damping element, sharp peaks in the sound waves can be effectively filtered, making the sound smoother and improving the user experience of the sound guiding structure.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

A sound transmission block 334 is provided between the sound-emitting surface 333, the fifth sound inlet 315 and the sixth sound inlet 316 and the sound outlet 320; the inner wall of the sound guide cavity 300 is provided with a groove 340 for fixing the sound outlet 320; the audio unit 200 includes a high-frequency moving iron unit 210, a mid-high frequency moving iron unit 220, a mid-frequency moving iron unit 230, a mid-low frequency moving iron unit 240 and a low-frequency moving iron unit 250; the high-frequency moving iron unit 210 is connected to the first sound inlet 311 and the second sound inlet 312, the mid-high frequency moving iron unit 220 is connected to the third sound inlet 313, the mid-frequency moving iron unit 230 is connected to the fourth sound inlet 314; the mid-low frequency moving iron unit 240 is connected to the fifth sound inlet 315; and the low-frequency moving iron unit 250 is connected to the sixth sound inlet 316.
[0024] By setting up audio units 200 and sound guide cavities 300, different audio units 200 can be connected to sound outlets 320 through different sound inlets 310 as needed, improving the compatibility and adjustment flexibility of the sound guide structure. By setting up sound guide cavities 300 and sound outlets 320, the sound entering the main body 100 through the sound inlet 310 can be propagated to different inner wall surfaces within the sound guide cavity 300, simulating different reflection processes and improving the user experience of the sound guide structure. Since the sound outlets 320 are stably connected through grooves 340, displacement of the main body 100 during use is avoided, thus improving the structural stability of the sound guide structure.
[0025] In another embodiment, the second sound inlet 312, the third sound inlet 313, the fourth sound inlet 314, the fifth sound inlet 315, and the sixth sound inlet 316 are distributed on one side of the main body 100, while the first sound inlet 311 is located on the other side of the main body 100. This structure ensures that the audio units 200 can be stably and evenly distributed on both sides of the main body 100, avoiding the sound inlet portions 310 corresponding to the audio units 200 from being too close and affecting the sound guiding effect of the sound guiding structure.
[0026] In another embodiment, the fourth sound inlet 314 is located between the third sound inlet 313 and the sound outlet 320. This structure ensures that the propagation distance through the fourth sound inlet 314 and the third reflective surface 333 is greater than the propagation distance through the third sound inlet 313 and the third reflective surface 333, optimizes the distribution of the sound guiding cavity 300 inside the main body 100, and effectively reduces the volume of the sound guiding structure.
[0027] In another embodiment, the fourth sound inlet 314, the fifth sound inlet 315, and the sixth sound inlet 316 are arranged in a triangle on the outer side of the main body 100. This structure ensures that the mid-frequency moving iron unit 230, the mid-low frequency moving iron unit 240, and the low-frequency moving iron unit 250 can be stably installed on the sound inlet section 310 according to user needs, thereby improving the integrity and stability of the sound guiding structure.
[0028] In another embodiment, the area of the third reflective surface 333 is larger than the area of the second reflective surface 332. This structure allows the sound-guiding cavity 300 to simulate different positions of the human ear, so that sound passes through the second sound inlet 312, the third sound inlet 313, and the fourth sound inlet 314 and then propagates through the third reflective surface 333 or the second reflective surface 332, thereby restoring sound signals of different frequencies and improving the sound guiding effect of the sound-guiding structure.
[0029] In another embodiment, the shape of the second reflective surface 332 corresponds to the cymba conchae; the shape of the third reflective surface 333 corresponds to the cavity conchae. This structure ensures that the high-frequency moving iron unit 210 and the second sound inlet 312 can simulate the process of high-frequency sound waves entering the ear canal after being reflected by the auricle, achieving a high-frequency transparency effect; it also ensures that the mid-to-high frequency moving iron unit 220 and the third sound inlet 313 can simulate the process of mid-to-high frequency sound waves entering the ear canal after being reflected by the auricle, achieving a high-frequency smoothness effect.
[0030] In another embodiment, the shape of the first reflective surface 331 corresponds to the antihelix. This structure ensures that the first sound inlet 311 and the first reflective surface 331 simulate the process of high-frequency sound waves entering the ear canal after being reflected by the auricle, thus achieving a high-frequency transparency effect.
[0031] In another embodiment, a damping element 350 for filtering sharp peaks is also provided between the sound inlet 310 and the audio unit 200. By providing the damping element 350, sharp peaks in the sound waves can be effectively filtered, making the sound smoother and improving the user experience of the sound guiding structure.
[0032] In another embodiment, the mid-low frequency moving iron unit 240 and the low frequency moving iron unit 250 are fixedly connected by a welding plate 260. By providing the welding plate 260, it is easier to stably install the audio unit 200 in the sound inlet 310, thereby improving the stability and structural integrity of the sound guiding structure.
[0033] Reference Figure 7 and Figure 8 This utility model embodiment also provides an earphone device, including a connecting part 400 and a sound guiding structure as described above; one end of the connecting part 400 is provided with a fixing platform 410 that cooperates with the groove 340, and the other end of the connecting part 400 is used to connect an ear tip.
[0034] Reference Figure 8 In another embodiment, a plurality of sealing rings 420 are provided below the fixing platform 410. By providing a plurality of sealing rings 420, the sealing performance between the connecting part 400 and the sound outlet 320 can be effectively improved, ensuring the working stability of the headphone device.
[0035] The working principle of this utility model will be further explained below.
[0036] In the production process of the headphone device in this embodiment, the main body 100 and audio unit 200 of corresponding size and specifications are first selected according to the usage environment and user needs. The main body 100 has a sound guide cavity 300, and one end of the sound guide cavity 300 has six sound inlets 310. The sound guide cavity 300 also has a first reflective surface 331, a second reflective surface 332, and a third reflective surface 333. Specifically, the sound inlets 310 include a first sound inlet hole 311, a second sound inlet hole 312, a third sound inlet hole 313, a fourth sound inlet hole 314, a fifth sound inlet hole 315, and a sixth sound inlet hole 316. The sound inlet 315 and the sixth sound inlet 316; the second sound inlet 312, the third sound inlet 313, the fourth sound inlet 314, the fifth sound inlet 315 and the sixth sound inlet 316 are distributed on one side of the main body 100, the first sound inlet 311 is located on the other side of the main body 100, and the second sound inlet 312, the third sound inlet 313 and the fourth sound inlet 314 are distributed in a triangle on the outer side of the main body 100; the first sound inlet 311 is connected to the sound outlet 320 through the first reflective surface 331, and the second sound inlet 312 is connected to the sound outlet 320 through the second reflective surface 332. The sound hole 320 is connected; the third sound inlet 313 and the fourth sound inlet 314 are connected to the sound outlet 320 through the third reflective surface 333; the fifth sound inlet 315 and the sixth sound inlet 316 are connected to the sound outlet 320 through the sound transmission block 334; the shape of the first reflective surface 331 corresponds to the antihelix, the shape of the second reflective surface 332 corresponds to the cymba conchae, and the shape of the third reflective surface 333 corresponds to the cavum conchae; in some embodiments, a damping element 350 is installed between the sound inlet 310 and the audio unit 200 to filter sharp peaks and make the sound smooth. The user experience of the sound guiding structure is improved. In some embodiments, the mid-low frequency balanced armature unit 240 and the low frequency balanced armature unit 250 are fixedly connected by a welding plate 260, so that the audio unit 200 can be stably installed in the sound inlet 310, which improves the stability and structural integrity of the sound guiding structure. Finally, by inserting the fixing platform 410 into the groove 340 and fixing the connecting part 400 into the sound outlet 320, the assembly of the headphone device is completed. The whole process is efficient and controllable, and there is no need to use glue or other adhesives for bonding, ensuring the structural integrity of the headphone device.
[0037] During the use of the headphone device, a high-frequency moving iron unit 210 is connected to the first sound inlet 311. After the circuit is turned on, sound is emitted. The sound wave is transmitted through the first sound inlet 311 to the first reflective surface 331. Since the first reflective surface 331 simulates the shape of the antihelix of the auricle, it simulates the process of high-frequency sound waves entering the ear canal after being reflected by the auricle. It resonates with extremely high-frequency sounds with frequencies between 16kHz and 18kHz, thereby achieving the extension effect of extremely high-frequency audio signals.
[0038] A high-frequency moving iron unit 210 is connected to the second sound inlet 312. After the circuit is turned on, sound is emitted. The sound wave propagates through the second sound inlet 312 to the second reflective surface 332. Since the second reflective surface 332 simulates the auricle and concha, it simulates the process of high-frequency sound waves entering the ear canal after being reflected by the auricle. It resonates with high-frequency audio signals with frequencies between 8kHz and 10kHz and between 13kHz and 15kHz, achieving a transparent effect for high-frequency audio signals.
[0039] The mid-to-high frequency moving iron unit 220 is connected to the third sound inlet 313. After the circuit is turned on, sound is emitted. The sound wave is transmitted through the third sound inlet 313 to the third reflector 333. Since the third reflector 333 simulates the concha of the auricle, it simulates the process of mid-to-high frequency sound waves entering the ear canal after being reflected by the auricle. Since the sound travels a long distance through the third reflector 333, it resonates with the mid-to-high frequency sound with a frequency of about 5kHz, thus achieving a smooth effect for the mid-to-high frequency audio signal.
[0040] The intermediate frequency moving iron unit 230 is connected to the fourth sound inlet 314. After the circuit is turned on, sound is emitted. The sound wave propagates through the fourth sound inlet 314 to the third reflector 333. Since the third reflector 333 simulates the concha cavity of the auricle, it simulates the process of the intermediate frequency sound wave entering the ear canal after being reflected by the auricle. Because the sound travels a short distance through the third reflector 333 at this time, it resonates with high frequency audio signals between 3kHz and 4kHz, thus achieving a stereo sound field effect.
[0041] A mid-to-low frequency balanced armature unit 240 is connected to the fifth sound inlet 315, and a low frequency balanced armature unit 250 is connected to the sixth sound inlet 316. After the circuit is turned on, sound is emitted. The sound waves propagate through the fifth sound inlet 315 and the sixth sound inlet 316 to the sound outlet 320. The sound outlet 320 contacts the external auditory canal via the connecting part 400. The sound waves propagate along the sound transmission block 334 and the connecting part 400, simulating the process of mid-to-low frequency sound waves propagating along the ground and the human body into the ear canal, achieving a shocking and three-dimensional effect.
[0042] As can be seen from the above description, the sound guiding structure and its headphone device of this utility model, by setting up an audio unit 200 and a sound guiding cavity 300, allows different audio units 200 to be connected to the sound outlet 320 through different sound inlets 310 as needed, thereby improving the compatibility and adjustment flexibility of the headphone device. By setting up a sound guiding cavity 300 and a sound outlet 320, the sound entering the main body 100 through the sound inlet 310 can be propagated to different inner wall surfaces within the sound guiding cavity 300, simulating different reflection processes and improving the user experience of the sound guiding structure. Since the sound outlet 320 is stably installed to the connecting part 400 through the groove 340, displacement of the main body 100 during use is avoided, thereby improving the installation stability of the headphone device.
[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
