Description

Technical Field

[0001] This utility model relates to the field of multi-speaker headphone technology, specifically, to a multi-speaker headphone. Background Technology

[0002] Headphones have become an indispensable accessory for modern electronic products. As people's demands for sound quality continue to rise, the sound quality of headphones is receiving increasing attention. Currently, most headphones only have a single speaker inside the casing, which can only emit sound at a single frequency and cannot simultaneously output high and low frequencies, resulting in poor stereo sound.

[0003] To overcome the above problems, an existing dual-speaker over-ear headphone uses a first speaker and a second speaker installed in each headphone body. The first speaker and the headphone mounting bracket form a first acoustic cavity, and the second speaker and the headphone mounting bracket form a second acoustic cavity. By independently setting the first and second acoustic cavities, the combination of the sound ranges of the first and second speakers can achieve a wider sound quality effect within the audible range, with better sound layering and detail, and can reproduce the original sound.

[0004] However, in this design, the first and second speakers are arranged in parallel directions and emit sound independently, without mixing the audio from the first and second speakers, resulting in poor stereo sound.

[0005] Therefore, a more optimized headphone structure needs to be considered. Utility Model Content

[0006] The main purpose of this invention is to provide a multi-speaker headphone that can have a more three-dimensional sound field effect and better overall sound quality.

[0007] To achieve the above-mentioned main objectives, the multi-speaker earphone provided by this utility model is provided with a left earphone and a right earphone. At least one of the left earphone and the right earphone includes an earphone shell, a main speaker and at least one auxiliary speaker. The earphone shell is provided with a first speaker cavity, a second speaker cavity and a front cavity. The first speaker cavity and the second speaker cavity are both connected to the front cavity and are spaced apart. The main speaker is installed in the first speaker cavity and the auxiliary speaker is installed in the second speaker cavity. The sound output direction of the main speaker and the auxiliary speaker are both facing the front cavity. The central axis of the main speaker and the central axis of the auxiliary speaker are set at an angle of 2 degrees to 75 degrees.

[0008] As can be seen from the above scheme, the multi-speaker headphones of this utility model, by setting a first speaker cavity, a second speaker cavity, and a front cavity, with both the first and second speaker cavities connected to the front cavity, and the main speaker installed in the first speaker cavity and the auxiliary speaker installed in the second speaker cavity, can allow the sound emitted by the main speaker and the auxiliary speaker to be mixed in the front cavity. At the same time, the central axis of the main speaker and the central axis of the auxiliary speaker are set at an angle of 2 to 75 degrees, which can make the output direction of the sound coincide, resulting in better audio mixing effect, more three-dimensional sound field effect, more delicate sound performance and wider sound range, and better sound resolution, thus improving the overall sound quality.

[0009] In a further embodiment, the first speaker cavity is provided with a first sound guide channel, the second speaker cavity is provided with a second sound guide channel, and the front cavity is provided with a third sound guide channel. The first, second, and third sound guide channels are spaced apart. The sound outlets of the first, second, and third sound guide channels are all located on the outer peripheral wall of the earphone shell.

[0010] Therefore, it can be seen that the first speaker cavity, the second speaker cavity, and the front cavity are equipped with independent sound guide channels to guide their respective audio to the outside of the headphone shell. This allows the sound of each set of sound generators in the cavity to be guided and directionally tuned by each channel, avoiding the mixing of the sound of each sound guide channel in the rear cavity and causing chaos of resonance harmonics.

[0011] In a further design, the sound outlets of the first, second, and third sound guide channels are all located in the top area of ​​the headphone housing.

[0012] Therefore, it can be seen that the sound outlets of the first sound guide channel, the second sound guide channel and the third sound guide channel are all located in the top area of ​​the headphone shell, which facilitates the mixed output of the audio from the first speaker cavity, the second speaker cavity and the front cavity.

[0013] In a further design, the main speaker is a low-to-mid frequency speaker, and the secondary speaker is a mid-to-high frequency speaker.

[0014] Therefore, by setting up mid-to-high frequency speakers and low-to-mid frequency speakers, a wider sound range and better sound quality can be achieved.

[0015] In a further design, the diameter of the main speaker is larger than that of the secondary speaker.

[0016] Therefore, the diameter of the main speaker is larger than that of the secondary speaker, which can accommodate the configuration of high-frequency and low-mid-frequency speakers.

[0017] In a further design, the diameter of the main speaker ranges from 20mm to 50mm; the diameter of the secondary speaker ranges from 6mm to 32mm.

[0018] Therefore, using a main speaker with a diameter range of 20mm to 50mm and a secondary speaker with a diameter range of 6mm to 32mm can improve audio performance.

[0019] In a further design, when there are two or more secondary horns, the central axes of all the secondary horns are on the same circumference.

[0020] Therefore, when there are multiple secondary speakers, placing the central axes of all secondary speakers on the same circumference allows them to be arranged around the main speaker, which can improve the sound effect.

[0021] In a further embodiment, the secondary loudspeakers include a first secondary loudspeaker, a second secondary loudspeaker, and a third secondary loudspeaker, with the second secondary loudspeaker located on the first side of the first secondary loudspeaker and the third secondary loudspeaker located on the second side of the first secondary loudspeaker.

[0022] Therefore, the first, second, and third speakers, with the second and third speakers positioned on either side of the first speaker, can balance the sound effect.

[0023] In a further design, the diameters of the second and third horns are both smaller than the diameter of the first horn; the diameters of the second and third horns are equal.

[0024] Therefore, it can be seen that by setting up a second and a third speaker of the same size on both sides of the first speaker with a larger diameter, the sound effect can be further balanced. Attached Figure Description

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0039] First embodiment of multi-speaker headphones:

[0040] In this embodiment, as Figure 1 As shown, the multi-speaker headphone is equipped with a left earphone 1 and a right earphone 2, and the structures of the left earphone 1 and the right earphone 2 are symmetrically arranged.

[0041] See Figure 2 and Figure 3 In this embodiment, the right earphone 2 includes an earphone housing 21, a main speaker 22, and a secondary speaker 23. The earphone housing 21 includes a first housing 211, a second housing 212, and a third housing 213. The first housing 211, the second housing 212, and the third housing 213 are fitted together. The third housing 213 is provided with a receiving cavity 2131. The first housing 211 and the second housing 212 are both installed in the receiving cavity 2131.

[0042] The earphone housing 21 contains a first speaker cavity 2121, a second speaker cavity 2122, and a front cavity 2111. Both the first speaker cavity 2121 and the second speaker cavity 2122 are connected to the front cavity 2111, and the first speaker cavity 2121 and the second speaker cavity 2122 are spaced apart. The front cavity 2111 is located on the first housing 211, and both the first speaker cavity 2121 and the second speaker cavity 2122 are formed by the cooperation of the first housing 211 and the second housing 212.

[0043] The main speaker 22 is installed in the first speaker cavity 2121, and the auxiliary speaker 23 is installed in the second speaker cavity 2122. The sound output direction of the main speaker 22 and the auxiliary speaker 23 is both facing the front cavity 2111. The central axis A of the main speaker 22 and the central axis B of the auxiliary speaker 23 are set at an angle of 2 degrees to 75 degrees.

[0044] See Figure 4 and Figure 5 The first speaker cavity 2121 is provided with a first sound guide channel 2123, the second speaker cavity 2122 is provided with a second sound guide channel 2124, and the front cavity 2111 is provided with a third sound guide channel 2125. The first sound guide channel 2123, the second sound guide channel 2124, and the third sound guide channel 2125 are arranged alternately. The first sound guide channel 2123, the second sound guide channel 2124, and the third sound guide channel 2125 are all formed by the cooperation of the first housing 211 and the second housing 212. The sound outlet 21231 of the first sound guide channel 2123, the sound outlet 21241 of the second sound guide channel 2124, and the sound outlet 21251 of the third sound guide channel 2125 are all located on the outer peripheral wall of the earphone housing 21. Preferably, the sound outlets 21231 of the first sound guide channel 2123, 21241 of the second sound guide channel 2124, and 21251 of the third sound guide channel 2125 are all located in the top area of ​​the earphone housing 21, which refers to the top area when worn. The first speaker cavity 2121, the second speaker cavity 2122, and the front cavity 2111, by setting independent sound guide channels, guide their respective audio to the outside of the earphone housing 21. This allows for focused sound guidance and channel-specific directional tuning of the sounds from each speaker within the cavity, preventing the sounds from mixing in the rear cavity and causing resonance harmonic distortion. Furthermore, the fact that the sound outlets of the first sound guide channel 2123, the second sound guide channel 2124, and the third sound guide channel 2125 are all located in the top area of ​​the earphone housing 21 facilitates the mixed output of the audio from the first speaker cavity 2121, the second speaker cavity 2122, and the front cavity 2111.

[0045] See Figure 6 and Figure 7 The first housing 211 is also provided with a connecting through hole 2112, and the front cavity 2111 is connected to the third sound guide channel 2125 through the connecting through hole 2112.

[0046] Furthermore, in this embodiment, the main speaker 22 is a low-to-mid-frequency speaker, and the auxiliary speaker 23 is a mid-to-high-frequency speaker. A low-to-mid-frequency speaker is a speaker capable of emitting audio within a set low-to-mid-frequency range, while a mid-to-high-frequency speaker is a speaker capable of emitting audio within a set mid-to-high-frequency range. The diameter of the main speaker 22 is larger than the diameter of the auxiliary speaker 23. By using mid-to-high-frequency and low-to-mid-frequency speakers, a wider sound range and better sound quality can be achieved. The larger diameter of the main speaker 22 compared to the auxiliary speaker 23 allows for the inclusion of both high-frequency and low-to-mid-frequency speakers.

[0047] Preferably, the diameter of the main speaker 22 ranges from 20mm to 50mm, and the diameter of the secondary speaker 23 ranges from 6mm to 32mm. The main speaker 22 has an outer diameter range of 20mm to 50mm, and the secondary speaker 23 has an outer diameter range of 6mm to 32mm. The output frequency of the main speaker 22 and the secondary speaker 23 can be adjusted by changing their size, thereby improving the audio effect. Of course, although both the main speaker 22 and the secondary speaker 23 are circular in this embodiment, those skilled in the art should know that they can also be elliptical, racetrack-shaped, square, rectangular, or other irregular shapes. The shapes of the main speaker 22 and the secondary speaker 23 can be the same or different.

[0048] In addition, the right earphone 2 also includes an earcup 24, which is installed on the opening in the sound outlet direction of the front cavity 2111. The earcup 24 can provide a seal and improve comfort when the user wears it.

[0049] As described above, the multi-speaker headphones of this invention, by setting a first speaker cavity 2121, a second speaker cavity 2122, and a front cavity 2111, with both the first speaker cavity 2121 and the second speaker cavity 2122 connected to the front cavity 2111, and the main speaker 22 installed in the first speaker cavity 2121 and the auxiliary speaker 23 installed in the second speaker cavity 2122, allow the sounds emitted by the main speaker 22 and the auxiliary speaker 23 to be mixed in the front cavity 2111. At the same time, the central axis A of the main speaker 22 and the central axis B of the auxiliary speaker 23 are set at an angle of 2 to 75 degrees, which allows the sound output directions to coincide, resulting in better audio mixing, a more three-dimensional sound field effect, more delicate sound performance, a wider sound range, and greater sound resolution, thus improving the overall sound quality.

The diameters of both the second secondary horn 432 and the third secondary horn 433 are smaller than the diameter of the first secondary horn 431; however, the diameters of the second secondary horn 432 and the third secondary horn 433 are equal. The central axis D of the first secondary horn 431, the central axis E of the second secondary horn 432, and the central axis F of the third secondary horn 433 are all set at an angle of 2 to 75 degrees to the central axis C of the main horn 42. Preferably, the angles between the central axis D of the first secondary horn 431, the central axis E of the second secondary horn 432, and the central axis F of the third secondary horn 433 and the central axis C of the main horn 42 are equal. The first speaker 431, the second speaker 432, and the third speaker 433 are positioned with the second speaker 432 and the third speaker 433 located on either side of the first speaker 431 to balance the sound. Further sound balance can be achieved by placing the second speaker 432 and the third speaker 433 of the same size on either side of the larger diameter first speaker 431.

[0056] See Figure 11The first speaker cavity 4121 is provided with a first sound guide channel 4123, the second speaker cavity 4122 is provided with a second sound guide channel 4124, and the front cavity 4111 is provided with a third sound guide channel 4125. The first sound guide channel 4123, the second sound guide channel 4124, and the third sound guide channel 4125 are arranged alternately. The first sound guide channel 4123, the second sound guide channel 4124, and the third sound guide channel 4125 are all formed by the cooperation of the first housing 411 and the second housing 412. The sound outlet 21231 of the first sound guide channel 4123, the sound outlet 21241 of the second sound guide channel 4124, and the sound outlet 21251 of the third sound guide channel 4125 are all located on the outer peripheral wall of the earphone housing 41. Preferably, the sound outlets 21231 of the first sound guide channel 4123, 21241 of the second sound guide channel 4124, and 21251 of the third sound guide channel 4125 are all located in the top area of ​​the earphone shell 41, which refers to the top area when worn. The first speaker cavity 4121, the second speaker cavity 4122, and the front cavity 4111, by setting independent sound guide channels, guide their respective audio to the outside of the earphone shell 41. This allows for focused sound guidance and channel-specific directional tuning of the sounds from each speaker within the cavity, preventing the sounds from mixing in the rear cavity and causing resonance harmonic distortion. Furthermore, the fact that the sound outlets of the first sound guide channel 4123, the second sound guide channel 4124, and the third sound guide channel 4125 are all located in the top area of ​​the earphone shell 41 facilitates the mixed output of the audio from the first speaker cavity 4121, the second speaker cavity 4122, and the front cavity 4111.

[0057] See Figure 12 and Figure 13 The first housing 411 is also provided with a connecting through hole 4112, and the front cavity 4111 is connected to the third sound guide channel 4125 through the connecting through hole 4112.

[0058] Furthermore, in this embodiment, the main speaker 42 is a low-to-mid-frequency speaker, and the auxiliary speaker 43 is a mid-to-high-frequency speaker. A low-to-mid-frequency speaker is a speaker capable of emitting audio within a set low-to-mid-frequency range, while a mid-to-high-frequency speaker is a speaker capable of emitting audio within a set mid-to-high-frequency range. The diameter of the main speaker 42 is larger than the diameter of the auxiliary speaker 43. By using both mid-to-high-frequency and low-to-mid-frequency speakers, a wider sound range and better sound quality can be achieved. The larger diameter of the main speaker 42 compared to the auxiliary speaker 43 allows for the inclusion of both high-frequency and low-to-mid-frequency speakers.
