Detailed implementation manners
[0025] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. Now, with reference to the drawings, the preferred embodiments of the present utility model will be described in detail.
[0026] As Figures 1 to 3 shown, an embodiment of the present utility model provides an earmuff 100, including: a housing 110, and a woofer 120 and a tweeter 130 disposed in the housing 110. The housing 110 includes an outer shell 112 and a cover body 114 that are buckled to each other. The woofer 120 is located at the center of the outer shell 112, and the tweeter 130 is located on one side of the woofer 120. A first sound outlet channel 116 corresponding to the woofer 120 and a second sound outlet channel 118 corresponding to the tweeter 130 are disposed in the housing 110, and the first sound outlet channel 116 and the second sound outlet channel communicating with the tweeter 130 converge outside the cover body 114.
[0027] Specifically, by setting the housing 110 as the mutually snap-fitting outer shell 112 and cover 114, it is convenient to set the woofer 120 and tweeter 130 inside the outer shell 112, and then the cover 114 can be snapped onto the outer shell 112 to complete the assembly. Among them, the woofer 120 is located at the center of the outer shell 112 so as to be directly corresponding to the human ear during use and reduce the loss of sound. According to the different structural forms of the woofer 120, the woofer 120 is only relatively closer to the center of the outer shell 112 than the tweeter 130. For example, when the woofer 120 is circular, it can be at the exact center of the outer shell 112; when the woofer 120 is annular, it can be in the annular area around the center, not at the absolute center position. In addition, through the first sound outlet channel 116 corresponding to the woofer 120 and the second sound outlet channel 118 corresponding to the tweeter 130, it is convenient for the sound emitted by the woofer 120 to be transmitted through the first sound outlet channel 116 and the sound emitted by the tweeter 130 to be transmitted through the second sound outlet channel 118, avoiding mutual influence inside the outer shell 112.
[0028] In the earphone housing 100 provided by the embodiment of the present application, by respectively arranging the woofer 120 and the tweeter 130 inside the housing 110, during use, the woofer 120 and the tweeter 130 can respectively emit sounds within their respective frequency ranges, and finally the sounds can be converged outside the cover 114 through the first sound outlet channel 116 and the second sound outlet channel 118. At this time, the human ear can hear the mixed sound with enhanced sound quality to ensure the final sound quality. In addition, by using the woofer 120 and the tweeter 130 in combination, compared with using a single speaker to achieve the required sound quality, there is no need to use a speaker with higher requirements to meet the use requirements, which is beneficial to reducing the production cost. During assembly, only the woofer 120 needs to be located at the center of the outer shell 112, the tweeter 130 is located on one side of the woofer 120, and the first sound outlet channel 116 and the second sound outlet channel 118 are used to perform frequency division and sound convergence in the earphone housing 100 to improve the required sound quality and reduce the production cost.
[0029] As Figure 2 、 Figure 4 and Figure 5 shown, the first sound outlet channel 116 includes a first half 1122 arranged inside the outer shell 112 and a second half 1142 arranged on one side of the cover 114. The first half 1122 and the second half 1142 enclose to form the first sound outlet channel 116, and a first sound outlet hole 1146 corresponding to the first sound outlet channel 116 is arranged on the cover 114.
[0030] Specifically, by disposing a first half body 1122 within the housing 112 and a second half body 1142 on one side of the cover 114, the first half body 1122 and the second half body 1142 not only serve as reinforcing ribs to ensure the structural strength of the housing 112 and the cover 114, but also cooperate to enclose and form a first sound output channel 116. As a result, when the woofer 120 produces sound, the sound can propagate along the first sound output channel 116, making the sound more concentrated and avoiding the influence of the tweeter 130. Furthermore, by disposing a first sound output hole 1146 on the cover 114 corresponding to the first sound output channel 116, the sound is ultimately emitted from the first sound output hole 1146 and transmitted to the human ear, reducing sound loss.
[0031] like Figure 2 、 Figure 4 and Figure 5 As shown, the second sound outlet channel 118 includes a first enclosure 1124 arranged in the shell 112, and a second enclosure 1144 arranged on one side of the cover body 114. The first enclosure 1124 and the second enclosure 1144 enclose the second sound outlet channel 118, and a second sound outlet hole 1148 corresponding to the second sound outlet channel 118 is provided on the cover body 114.
[0032] Specifically, by providing a first enclosure 1124 within the housing 112 and a second enclosure 1144 on one side of the cover 114, the first enclosure 1124 and the second enclosure 1144 not only serve as reinforcing ribs to ensure the structural strength of the housing 112 and the cover 114, but also cooperate with each other to form the second sound output channel 118. In this way, when the tweeter 130 produces sound, the sound can be transmitted along the second sound output channel 118, making the sound more concentrated and avoiding the influence of the woofer 120. In addition, by providing a second sound output hole 1148 on the cover 114 corresponding to the second sound output channel 118, the sound is ultimately emitted from the second sound output hole 1148 and transmitted to the human ear, thereby reducing sound loss.
[0033] like Figure 2 As shown, a grille 1146 a is provided at the first sound outlet 1146 .
[0034] The above-mentioned form can protect the first sound output channel 116 while ensuring smooth sound output, which is beneficial to ensuring reliability during use.
[0035] like Figure 2 As shown, the second sound outlet 1148 includes a sound collecting groove 1148 a provided on one side of the cover 114 , and a buckle cover 1148 b provided on the side of the cover 114 away from the housing 112 .
[0036] Specifically, since the woofer 120 is located at the center of the housing 112 and the tweeter 130 is located on one side of the woofer 120, during the process of conducting sound to the human ear, the first sound outlet hole 1146 can be exactly corresponding to the first sound outlet channel 116, and the second sound outlet hole 1148 is required to guide the second sound outlet channel 118 on the side to the first sound outlet hole 1146 to form a sound converging structure. Therefore, a sound converging groove 1148a is provided on one side of the cover 114, and a snap cover 1148b is provided on the side of the cover 114 facing away from the housing 112. The snap cover 1148b can be detachably connected to the cover 114, which is convenient for processing and fitting.
[0037] As Figure 2 and Figure 6 shown, the sound converging groove 1148a includes an arc-shaped groove bottom 1148a1 that bends away from the housing side, and the length of the sound converging groove 1148a extending towards the center of the cover 114 is greater than the length of the snap cover 1148b extending towards the center of the cover 114.
[0038] Specifically, through the arc-shaped groove bottom 1148a1 that bends away from the housing side, it is beneficial to guide the sound emitted from the second sound outlet channel 118 towards the center of the earcup 100 while guiding it towards the human ear to ensure the sound transmission effect. In addition, the length of the sound converging groove 1148a extending towards the center of the cover 114 is greater than the length of the snap cover 1148b extending towards the center of the cover 114. When the sound exits the second sound outlet hole 1148, it can still propagate along the arc-shaped groove bottom 1148a1 and be affected by the arc-shaped groove bottom 1148a1 to be transmitted towards the human ear. At this time, it can avoid being affected by the snap cover 1148b, which is beneficial to improving the sound propagation quality and reducing the loss during the sound propagation process.
[0039] In an alternative embodiment of the present application, a midrange speaker is further provided inside the housing 112. The midrange speaker and the tweeter 130 are respectively located on opposite sides of the woofer 120, and a third sound outlet channel corresponding to the tweeter 130 is provided inside the cover 110.
[0040] Specifically, in order to ensure full-range coverage of the final sound and improve the sound quality, a midrange speaker can be added to play a better complementary role. When setting the midrange speaker, the midrange speaker and the tweeter 130 are respectively located on opposite sides of the woofer 120. The third sound outlet channel provided inside the cover 110 corresponding to the tweeter 130 can have the same structural form as the second sound outlet channel 118 to ensure the required sound transmission effect.
[0041] In an alternative embodiment of the present application, the woofer 120 is the main sound generating unit, and the tweeter 130 and the midrange speaker are auxiliary sound generating units.
[0042] Specifically, the woofer 120 is located at the center of the housing 112 and has a direct correspondence with the human ear. It is received by the human ear as the direct sound the most. The tweeter 130 and the midrange speaker are located on the sides of the housing 112 and are mostly transmitted to the human ear in the form of reflected sound to form a full-range sound field, thereby ensuring the sound quality heard.
[0043] In an alternative embodiment of the present application, the audio range of the woofer 120 is 100 Hz - 2000 Hz; the audio range of the tweeter 130 is 200 Hz - 40000 Hz; the audio range of the midrange speaker is 250 Hz - 20000 Hz.
[0044] By adopting the above method, the designed frequency range can be specifically processed, which can ensure that the sounds in each frequency range can be reproduced best. Since the woofer 120, the tweeter 130 and the midrange speaker only process the frequency range they are best at, the nonlinear distortion during sound generation can be reduced, thereby improving the sound quality. A better stereo effect can also be produced.
[0045] The present utility model also discloses a pair of headphones, including an ear strap and the earcup 100 in the foregoing embodiment, and the earcup 100 is connected to the ear strap. This pair of headphones has the same structure and beneficial effects as the earcup 100 in the foregoing embodiment. The structure and beneficial effects of the earcup 100 have been described in detail in the foregoing embodiment and will not be elaborated herein.
[0046] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit it. For those skilled in the art, the technical solutions recorded in the above embodiments can be modified, or some of the technical features can be equivalently replaced; and all such modifications and replacements should fall within the protection scope of the appended claims of the present utility model.
