Description

Technical Field

[0001] This invention relates to the field of headphones, and more specifically, to a gaming headset. Background Technology

[0002] Unlike regular headphones that focus on reproducing the three frequency ranges, gaming headsets need to amplify sounds such as footsteps, reload sounds, and bullet whistles to meet players' needs for sound positioning and immersion. Existing gaming headsets often achieve immersion by intentionally increasing gain in the 60–250Hz range, but this triggers frequency masking effects. For example, the aftersound of gunshots and the aftershocks of explosions can directly mask mid-to-high frequency transient details such as footsteps, reload sounds, and the friction of fabric. Summary of the Invention

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] like Figure 1 The diagram shows a schematic of a gaming headset provided in an embodiment of the present invention. This gaming headset can play audio and is particularly suitable for playing game audio. The gaming headset of this embodiment includes a headband 20 and two sound-generating components. The headband 20 is arc-shaped to fit the human head. The two sound-generating components are respectively connected to the two ends of the headband 20. When worn, the two sound-generating components are located at the two ears, and the headband 20 rests on the head. The connection structure between the headband 20 and the sound-generating components can adopt conventional methods in the art, and will not be described in detail here.

[0026] Combination Figure 2 , Figure 3As shown, each sound-generating component includes an ear shell 11, an earmuff 12, a sound cavity shell 13, a mounting bracket 14, a first speaker 15, a second speaker 16, and a third speaker 17. The earmuff 12 is mounted on one side of the ear shell 11, and the mounting bracket 14, the first speaker 15, the second speaker 16, and the third speaker 17 are respectively mounted between the ear shell 11 and the earmuff 12.

[0027] The aforementioned ear shell 11 can be made of hard materials such as metal or plastic. It is roughly bowl-shaped to fit the human ear and includes a main mounting cavity 111, a main opening, a first pressure relief hole 112, and a second pressure relief hole 113. The main opening is located on the front side of the main mounting cavity 111 (i.e., the side adjacent to the ear cup 12) and is connected to the main mounting cavity 111. The first pressure relief hole 112 and the second pressure relief hole 113 are respectively connected to the main mounting cavity, and the first pressure relief hole 112 and the second pressure relief hole 113 are respectively located on the back side or the periphery of the main mounting cavity 111 (i.e., the back side or periphery of the ear shell 11).

[0028] The acoustic cavity shell 13 can also be made of hard materials such as metal or plastic. It is roughly bowl-shaped and located in the main mounting cavity 111 of the ear shell 11. The acoustic cavity shell 13 forms a first rear acoustic cavity 131 and a second rear acoustic cavity 132 that are isolated from each other. The openings of the first rear acoustic cavity 131 and the second rear acoustic cavity 132 both face the main opening of the ear shell 11. The first rear acoustic cavity 131 is connected to the first pressure relief hole 112 on the ear shell 11, and the second rear acoustic cavity 132 is connected to the second pressure relief hole 113 on the ear shell 11. That is, the first rear acoustic cavity 131 is connected to the outside through the first pressure relief hole 112, and the second rear acoustic cavity 132 is connected to the outside through the second pressure relief hole 113. Specifically, the side wall of the first rear acoustic cavity 131 of the acoustic cavity shell 13 has a connecting port 134, the side wall of the second rear acoustic cavity has a connecting port 135, and the outer side has two connecting pipes. That is, after the acoustic cavity shell 13 is installed into the main mounting cavity 111 of the ear shell 11, the first rear acoustic cavity 131 is connected to the outside through the connecting port 134, the corresponding connecting pipe and the first pressure relief hole 112, and the second rear acoustic cavity 132 is connected to the outside through the connecting port 135, the corresponding connecting pipe and the second pressure relief hole 113.

[0029] The mounting bracket 14 can also be made of rigid materials such as metal or plastic, and its overall shape is a sheet adapted to fit the main opening of the ear shell 11. The mounting bracket 14 is installed at the main opening of the ear shell 11 and seals the main mounting cavity 111 of the ear shell 11 and the first rear acoustic cavity 131 and the second rear acoustic cavity 132 of the acoustic cavity shell 13. Those skilled in the art will understand that the mounting bracket 14 does not need to seal the main mounting cavity 111, the first rear acoustic cavity 131 and the second rear acoustic cavity 132, that is, no sealing structure is required between the mounting bracket 14 and the ear shell 11 and the acoustic cavity shell 13.

[0030] The first speaker 15, the second speaker 16, and the third speaker 17 are all mounted on the mounting bracket 14. The first speaker 15 has better sound quality in the low-frequency range (e.g., 20Hz–250Hz) than the second speaker 16 and the third speaker 17 in the low-frequency range. The second speaker 16 has better sound quality in the mid-frequency range (e.g., 250Hz–4kHz) than the first speaker 15 and the third speaker 17 in the mid-frequency range. The third speaker 17 has better sound quality in the high-frequency range (e.g., 4kHz–20kHz) than the first speaker 15 and the second speaker 16 in the high-frequency range. When the mounting bracket 14 is installed into the mounting port of the ear shell 11, the main body of the first speaker 15 is located in the first rear acoustic cavity 131, and the main body of the second speaker 16 is located in the second rear acoustic cavity 132. As will be understood by those skilled in the art, superior sound quality refers to a positive offset of the frequency response curve relative to the target curve (such as the Harman curve, flat monitoring curve, etc.). For example, for the first speaker 15, its overall frequency response is 2–5 dB above the target curve in the 20–450 Hz range, without any "booming peak" exceeding +6 dB, and is mostly a broad and flat rise; for the second speaker 16, its frequency response is close to or slightly above the target curve in the 250 Hz–4 kHz range, without any dips (especially in the 1–3 kHz vocal core area); for the third speaker 17, its frequency response extends smoothly in the 4 kHz–16 kHz range, is above the target curve without any jagged spikes, and has no sharp +8 dB sibilance peak, but gently extends to 16 kHz and then naturally declines. Specifically, such as Figure 5-7 The figures shown are the frequency response curves of the first speaker 15, the second speaker 16, and the third speaker 17, respectively. None of these three speakers can provide superior sound effects across the entire frequency range.

[0031] The earmuff 12 is located on the side of the mounting bracket 14 facing away from the ear shell 11, for example, it can be fixed to the front of the mounting bracket 41. The earmuff 12 includes a ring-shaped soft pad, and a front sound cavity 121 is formed within the area enclosed by the soft pad. The sound-emitting surfaces of the first speaker 15, the second speaker 16, and the third speaker 17 all face the front sound cavity 121. When worn, the earmuff 12 covers the human ear, and the front sound cavity is located outside the entrance of the external auditory canal, so that the sound emitted by the first speaker 15, the second speaker 16, and the third speaker 17 can directly enter the external auditory canal. Specifically, the earmuff 12 can adopt a structure commonly used in the art, which will not be described in detail here.

[0032] The aforementioned over-ear gaming headset, by setting a sound cavity shell 13 with a first rear sound cavity 131 and a second rear sound cavity 132 within the main mounting cavity 111 of the ear shell 11, and mounting the main bodies of the first speaker 15 and the second speaker 16 on the mounting bracket 14 into the first rear sound cavity 131 and the second rear sound cavity 132 of the sound cavity shell 13 respectively, allows the first speaker 15, the second speaker 16, and the third speaker 17 to emit sound in their respective advantageous frequency bands, and greatly reduces the mutual interference between the first speaker 15 and the second speaker 16. This ensures an immersive gaming experience while preventing sound details from being masked. Furthermore, by utilizing the superior sound effect frequency bands of the first speaker 15, the second speaker 16, and the third speaker 17 respectively, the cost can be significantly reduced compared to using a single high-quality speaker.

[0033] In one embodiment of the present invention, the mounting bracket 14 has a first sound outlet 141 adapted to the sound-emitting surface (i.e., diaphragm) of the first speaker 15 and a second sound outlet 142 adapted to the sound-emitting surface of the second speaker 16. The first speaker 15 and the second speaker 16 are respectively fixed to the back of the mounting bracket 14, with the sound-emitting surface of the first speaker 15 facing the first sound outlet 141 and the sound-emitting surface of the second speaker 16 facing the second sound outlet 142. That is, the sound emitted by the first speaker 15 and the second speaker 16 enters the front sound cavity 121 through the first sound outlet 141 and the second sound outlet 142, respectively. Furthermore, a support member 1471 is formed inside the first sound outlet 141, and the third speaker 17 is fixed to the support member 1471. The sound-emitting surface of the third speaker 17 protrudes from the front of the mounting bracket 14, that is, the third speaker 17 is stacked in front of the sound-emitting surface of the first speaker 15. In particular, to avoid the presence of the third speaker 17 affecting the sound output of the first speaker 15, the support member 1471 may be composed of annular ribs and radial ribs, and the third speaker 17 may be located in the center of the first sound outlet 141.

[0034] The above structure allows for a compact installation of the first speaker 15, the second speaker 16, and the third speaker 17, ensuring sound quality while occupying relatively little space. Furthermore, since the sound-emitting surfaces of the first speaker 15 and the second speaker 16 are essentially on the same plane, their sound interference is relatively small; and since the third speaker 17 and the first speaker 15 have significantly different frequency ranges, even if they are "stacked," it will not have a significant impact on the sound quality.

[0035] In one embodiment of the present invention, a first mounting groove 145 and a second mounting groove 146 are formed on the back side of the mounting bracket 14. A first sound outlet 141 extends from the bottom wall of the first mounting groove 145 to the front side of the mounting bracket 14, and a second sound outlet 142 extends from the bottom wall of the second mounting groove 146 to the front side of the mounting bracket 14. The shape and size of the first mounting groove 145 are adapted to the shape and size of the first speaker 15, and the shape and size of the second mounting groove 146 are adapted to the shape and size of the second speaker 16. For example, when the sound-emitting surfaces of the first speaker 15 and the second speaker 16 are circular, the diameters of the first speaker 15 and the second speaker 16 are slightly smaller than the diameters of the first mounting groove 145 and the second mounting groove 146, respectively. The sound-emitting surface of the first speaker 15 is embedded in the first mounting groove 145, and the sound-emitting surface of the second speaker 16 is embedded in the second mounting groove 146. Furthermore, a third mounting groove 1472 is formed on the support member 1471, and the third speaker 17 is installed in the third mounting groove 1472, with the sound-emitting surface of the third speaker 17 exposed in the third mounting groove 1472. Specifically, the first speaker 15, the second speaker 16, and the third speaker 17 can all be fixed in their respective mounting grooves by adhesive bonding.

[0036] The above structure ensures that the first speaker 15, the second speaker 16, and the third speaker 17 are stably fixed. Since all three speakers are fixed to the mounting bracket 14, the mounting bracket 14 and the three speakers can be installed and disassembled as a whole, which greatly facilitates the assembly and maintenance of the product.

[0037] In one embodiment of the present invention, the diameter of the sound-emitting surface of the first speaker 15 is greater than the diameter of the sound-emitting surface of the second speaker 16, and the diameter of the sound-emitting surface of the second speaker 16 is greater than the diameter of the sound-emitting surface of the third speaker 17. That is, the diameter of the diaphragm of the first speaker 15 is the largest, the diameter of the diaphragm of the second speaker 16 is the second largest, and the diameter of the diaphragm of the third speaker 17 is the smallest.

[0038] Furthermore, within the acoustic cavity shell 13, the second rear acoustic cavity 132 is located above the first rear acoustic cavity 131. Correspondingly, two second speakers 16 are mounted on the upper back of the mounting bracket 14, and the first speaker 15 is located below the two second speakers 16. The distances from the center of the sound-emitting surface of the two second speakers 16 to the center of the sound-emitting surface of the first speaker 15 are equal. Accordingly, the mounting bracket 14 has two second sound outlet holes 142 and two second mounting grooves 146 on its back.

[0039] Each sound-emitting component of the headset includes two second speakers 16, one first speaker 15, and one third speaker 17, with the two second speakers 16 arranged side by side above the first speaker 15 and the third speaker 17, thereby meeting the immersive experience requirements in gaming scenarios.

[0040] Specifically, the main operating frequency response of the first speaker 15 is 20Hz–450Hz, the main operating frequency response of the second speaker 16 is 250Hz–4kHz, and the main operating frequency response of the third speaker 17 is 4kHz–20kHz; furthermore, the diameter of the diaphragm of the first speaker 15 is 40mm±4mm, the diameter of the diaphragm of the second speaker 16 is 23mm±2mm, and the diameter of the diaphragm of the third speaker 17 is 10±1mm. This structure can achieve a better sound performance in a smaller space.

[0041] In one embodiment of the present invention, the mounting bracket 14 is further provided with two first strip-shaped holes 143 and one second strip-shaped hole 144. The first strip-shaped holes 143 and the second strip-shaped hole 144 penetrate the front and back surfaces of the mounting bracket 14, respectively, and the radial areas of the first strip-shaped holes 143 and the second strip-shaped hole 144 are between 19 and 40 square millimeters. The long axes of the two first strip-shaped holes 143 are along a first direction (e.g., ...). Figure 3 The second slot 144 is positioned along the direction indicated by arrow X in the diagram, and is located on both sides of the first speaker 15. The long axis of the second slot 144 is along the second direction (as shown by arrow X in the diagram). Figure 3 (As indicated by the arrow Y in the image) is positioned above the two second speakers 16. Figure 3 As shown, the first direction and the second direction are perpendicular to each other, and the second direction is the arrangement direction of the two second speakers 16.

[0042] Since the first slot 143 is adjacent to the first sound outlet 141, the first slot 143 can balance the air pressure changes caused by the diaphragm vibrations of the first speaker 15 and the third speaker 17 by connecting to the first rear acoustic cavity 131 (and thus connecting to the outside through the connecting port 134, the corresponding connecting pipe, and the first pressure relief hole 112), minimizing the impact of the air pressure changes caused by the diaphragm vibrations of the first speaker 15 and the third speaker 17 on the sound production of the second speaker 16. Similarly, since the second slot 144 is adjacent to the second sound outlet 142, the second slot 144 can balance the air pressure changes caused by the diaphragm vibrations of the second speaker 16 by connecting to the second rear acoustic cavity 132 (and thus connecting to the outside through the connecting port 135, the corresponding connecting pipe, and the second pressure relief hole 113), minimizing the impact of the air pressure changes caused by the diaphragm vibrations of the second speaker 16 on the sound production of the first speaker 15 and the third speaker 17.

[0043] Combination Figure 8As shown, in one embodiment of the present invention, a first groove 1491 and a second groove 1492 are formed on the front side of the mounting bracket 14, wherein the first sound outlet 141 extends from the bottom wall of the first groove 1491 to the back side of the mounting bracket 14, and the second sound outlet 142 extends from the bottom wall of the second groove 1492 to the back side of the mounting bracket 14. In the direction from top to bottom, the bottom walls of the first groove 1491 and the second groove 1492 are inclined toward the back side of the mounting bracket 14, and a step is formed at the junction of the first groove 1491 and the second groove 1492.

[0044] With the above structure, when the gaming headset is worn on the head, the first speaker 15, the second speaker 16, and the third speaker 17 are all tilted, thus separating the sound-emitting surface of the second speaker 16 from that of the first speaker 15 by a step. This further reduces the interference between the sound output of the second speaker 16 and the sound output of the first speaker 15 and the third speaker 17. Those skilled in the art will understand that, to ensure the depth of the first groove 1491 and the second groove 1492, the portion of the back of the mounting bracket 14 corresponding to the first groove 1491 and the second groove 1492 may protrude beyond the edge of the back of the mounting bracket 14.

[0045] In one embodiment of the present invention, the aforementioned acoustic cavity shell 13 is bowl-shaped and mounted on the back of the mounting bracket 14, and when the mounting bracket 14 is fixed to the main opening of the ear shell 11, the acoustic cavity shell 13 is suspended in the main mounting cavity 111 of the ear shell 11.

[0046] The acoustic cavity shell 13, mounting bracket 14, first speaker 15, second speaker 16, and third speaker 17 are mounted as a single unit onto the ear shell 11, thereby improving the product's integration and simplifying the assembly process. Furthermore, since the acoustic cavity shell 13 is suspended within the main mounting cavity 111 via the mounting bracket 14 and does not contact the side wall of the main mounting cavity 111, collisions between the acoustic cavity shell 13 and the side wall of the main mounting cavity 111 (i.e., the ear shell 11) can be avoided, thus preventing abnormal noises and further improving sound quality.

[0047] In particular, combined Figure 2 , Figure 4As shown, the aforementioned acoustic cavity shell 13 has an annular flange 136 and a partition 133 for separating the first rear acoustic cavity 131 and the second rear acoustic cavity 132, wherein the annular flange 136 surrounds the first rear acoustic cavity 131 and the second rear acoustic cavity 132; correspondingly, the back of the mounting bracket 14 has an annular groove 1481 and a strip groove 1482 corresponding to the partition 133, and when the acoustic cavity shell 13 is installed on the back of the mounting bracket 14, the annular flange 136 is embedded in the annular groove 1481, and the top end of the partition 133 is embedded in the strip groove 1482. With the above structure, the acoustic cavity shell 13 can be stably fixed to the mounting bracket 14, and the occurrence of abnormal noise caused by collision between the two can be reduced. Those skilled in the art will understand that the top of the annular flange 136 and the partition 133 can be tightly fitted with the annular groove 1481 and the strip groove 1482, or adhesive can be added to the annular groove 1481 and the strip groove 1482 to further improve the stability of the combination.

[0048] Furthermore, wire holes can be provided on the inner walls of the first rear acoustic cavity 131 and the second rear acoustic cavity 132 of the acoustic cavity shell 13, respectively, for wires used to electrically connect the first speaker 15 and the second speaker 16 to pass through. The front of the mounting bracket 14 and the support member 1471 can have wire grooves for the routing of wires used to electrically connect the third speaker 17. For example, to avoid collisions, the wires can be glued and fixed after being installed in the wire grooves.

[0049] In one embodiment of the present invention, the aforementioned over-ear gaming headset further includes a control circuit board disposed within the main mounting cavity 111 of the ear shell 11. This control circuit board has a first audio decoding unit for outputting low-frequency decoding signals, a second audio decoding unit for outputting mid-frequency decoding signals, and a third audio decoding unit for outputting high-frequency decoding signals. The first audio decoding unit is electrically connected to a first speaker, the second audio decoding unit is electrically connected to a second speaker, and the third audio decoding unit is electrically connected to a third speaker, thereby enabling the first speaker 15, the second speaker 16, and the third speaker 17 to respectively handle low-frequency, mid-frequency, and high-frequency sound output.
