Description

Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to an electronic device. Background Technology

[0002] In related technologies, electronic devices are equipped with sound-generating devices inside, and the electronic devices are equipped with sound outlet holes and sound outlet channels. By using the sound outlet holes and sound outlet channels, the sound waves of the sound-generating devices are exported to achieve sound generation.

[0003] With the development of electronic devices, the requirements for their appearance are getting higher and higher. In order to improve the appearance performance of electronic devices, the size of the sound holes and sound channels of electronic devices is getting smaller and smaller. This makes it easy for users to block the sound holes and sound channels due to improper operation during the use of electronic devices. Similarly, long-term dust can also block the sound holes and sound channels, resulting in noise and a deterioration of the sound effect. Summary of the Invention

[0004] The purpose of this application is to provide an electronic device that can solve the problem of noise caused by the sound outlet of the electronic device being blocked or sealed in the related art.

[0005] This application provides an electronic device, including a device body and a sound-emitting device. The sound-emitting device is disposed on the device body. The device body has a sound guiding channel, a sound output channel, a main sound output hole, and an auxiliary sound output hole. The sound-emitting end of the sound-emitting device faces the sound guiding channel. The sound guiding channel communicates with the auxiliary sound output hole and the main sound output hole through the sound output channel. The auxiliary sound output hole is disposed adjacent to the main sound output hole and is located on the side of the main sound output hole away from the sound guiding channel.

[0006] In this embodiment, the device body is provided with an auxiliary sound outlet and a main sound outlet. When the main sound outlet is not blocked, since the auxiliary sound outlet is located on the side of the main sound outlet away from the sound guiding channel, the resistance to sound flowing into the auxiliary sound outlet is greater than the resistance to sound flowing into the main sound outlet. Therefore, most of the sound emitted by the sound-generating device is emitted through the main sound outlet via the sound outlet channel. When at least part of the main sound outlet is blocked, the acoustic resistance of sound flowing through the main sound outlet increases. In comparison, sound is more likely to enter the auxiliary sound outlet from the sound outlet channel and achieve normal sound emission through the auxiliary sound outlet, avoiding noise. Moreover, since the auxiliary sound outlet is located near the main sound outlet, the sound emission area of ​​the auxiliary sound outlet is basically the same as that of the main sound outlet, so sound leakage is less likely to occur, preventing sound leakage caused by sound flowing to other areas when the main sound outlet is blocked.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0019] The electronic device provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0020] Please refer to Figures 1-6 The electronic device disclosed in this application includes a device body 100 and a sound-generating device 200. The device body 100 serves as the mounting base for the sound-generating device 200, which is disposed within the device body 100. Optionally, the sound-generating device 200 is disposed inside the device body 100. The device body 100 is provided with a sound guiding channel 111, a sound output channel 112, a main sound output hole 113, and an auxiliary sound output hole 114. The sound-generating end of the sound-generating device 200 faces the sound guiding channel 111 so that the sound signal emitted by the sound-generating device 200 can directly enter the sound guiding channel 111. The sound guiding channel 111 is connected to the auxiliary sound output hole 114 and the main sound output hole 113 through the sound output channel 112, respectively. Thus, the sound signal in the sound guiding channel 111 can flow out through the auxiliary sound output hole 114 and the main sound output hole 113 through the sound output channel 112.

[0021] The auxiliary sound outlet 114 is disposed adjacent to the main sound outlet 113, and the auxiliary sound outlet 114 is located on the side of the main sound outlet 113 away from the sound guide channel 111. That is, along the extension direction of the sound outlet channel 112, the distance between the auxiliary sound outlet 114 and the sound guide channel 111 is greater than the distance between the main sound outlet 113 and the sound guide channel 111. Optionally, both the auxiliary sound outlet 114 and the main sound outlet 113 can extend to the side wall of the sound outlet channel 112, or the main sound outlet 113 can extend to the side wall of the sound outlet channel 112, and the auxiliary sound outlet 114 can extend to the end of the sound outlet channel 112 away from the sound guide channel 111. Of course, this application does not impose specific limitations on the structure of the sound guide channel 111, the sound outlet channel 112, the auxiliary sound outlet 114, and the main sound outlet 113, as long as the corresponding functions can be achieved.

[0022] In this embodiment, the device body 100 is provided with an auxiliary sound outlet 114 and a main sound outlet 113. When the main sound outlet 113 is not blocked, since the auxiliary sound outlet 114 is located on the side of the main sound outlet 113 away from the sound guide channel 111, the resistance of sound flowing into the auxiliary sound outlet 114 is greater than the resistance of sound flowing into the main sound outlet 113. Therefore, most of the sound emitted by the sound-generating device 200 is emitted through the sound outlet channel 112 and emitted through the main sound outlet 113. When at least part of the main sound outlet 113 is blocked, the acoustic resistance of sound flowing through the main sound outlet 113 increases. In comparison, sound is more likely to enter the auxiliary sound outlet 114 from the sound outlet channel 112 and achieve normal sound emission through the auxiliary sound outlet 114, avoiding the generation of noise.

[0023] refer to Figure 4 and Figure 5As shown in the airflow diagram, when the main sound outlet 113 is not blocked, the airflow through the auxiliary sound outlet 114 is relatively small, and the airflow mainly flows out from the main sound outlet 113; when at least part of the main sound outlet 113 is blocked, the airflow through the auxiliary sound outlet 114 increases, indicating that the sound signal is more likely to enter the auxiliary sound outlet 114 from the sound outlet channel 112, and normal sound is achieved through the auxiliary sound outlet 114, avoiding the generation of noise.

[0024] Furthermore, since the auxiliary sound outlet 114 is located adjacent to the main sound outlet 113, the sound-emitting area of ​​the auxiliary sound outlet 114 is basically the same as that of the main sound outlet 113. Therefore, sound leakage is less likely to occur, preventing sound from flowing to other areas and causing sound leakage when the main sound outlet 113 is blocked. (Reference) Figure 6 The curves showing the change in sound leakage performance with frequency indicate that, when at least part of the main sound outlet 113 is blocked, the electronic devices in the related technologies that do not have an auxiliary sound outlet 114 and the electronic devices in this application that have an auxiliary sound outlet 114 show a high consistency in sound leakage in the low-frequency range. This shows that setting an auxiliary sound outlet 114 does not increase the sound leakage performance and is beneficial to ensuring the sound output effect.

[0025] In an optional embodiment, the auxiliary sound outlet 114 is directly connected to one end of the sound guide channel 111, or, as... Figures 1-2 As shown, an auxiliary sound guide cavity 300 is provided at the end of the sound outlet channel 112 away from the sound guide channel 111. An auxiliary sound outlet hole 114 is opened on the surface of the device body 100 corresponding to the auxiliary sound guide cavity 300, that is, the auxiliary sound outlet hole 114 is connected to the sound outlet channel 112 through the auxiliary sound guide cavity 300. When at least part of the main sound outlet hole 113 is blocked, the sound signal of the sound outlet channel 112 flows into the auxiliary sound guide cavity 300, and then the sound signal flows out through the auxiliary sound outlet hole 114. When the extension direction of the sound outlet channel 112 is not consistent with the axial direction of the auxiliary sound outlet hole 114, if the sound outlet channel 112 is directly connected to the auxiliary sound outlet hole 114, the sound signal needs to change direction rapidly in order to flow out from the auxiliary sound outlet hole 114. Therefore, the auxiliary sound guide cavity 300 is provided to facilitate the transition of the sound signal within the auxiliary sound guide cavity 300, which is conducive to the timely change of direction of the sound signal of the sound outlet channel 112, so that it can flow out smoothly from the auxiliary sound outlet hole 114.

[0026] In an optional embodiment, the flow area of ​​the auxiliary sound guide cavity 300 is smaller than the flow area of ​​the sound outlet channel 112, or the flow area of ​​the auxiliary sound guide cavity 300 is larger than the flow area of ​​the sound outlet channel 112. Optionally, the flow area of ​​both the auxiliary sound guide cavity 300 and the flow area of ​​the sound outlet channel 112 refer to the cross-sectional area of ​​a first plane, which is perpendicular to the extending direction of the sound outlet channel 112. Compared with the previous embodiment, in the latter embodiment, when at least a portion of the main sound outlet 113 is blocked, the resistance of the sound signal flowing from the sound outlet channel 112 into the auxiliary sound guide cavity 300 is reduced, which is conducive to the smooth flow of the sound signal to the auxiliary sound outlet 114, and finally smoothly flowing out of the auxiliary sound outlet 114. This avoids the increased resistance of the sound signal flowing into the auxiliary sound guide cavity 300, which would cause the sound signal to still mainly flow through the main sound outlet 113 and thus generate noise.

[0027] In an optional embodiment, the top wall of the auxiliary sound guide cavity 300 is positioned lower than the top wall of the sound outlet channel 112. Thus, the flow area at the connection between the auxiliary sound guide cavity 300 and the sound outlet channel 112 is smaller than the flow area of ​​the sound outlet channel 112. This means that as the sound signal flows from the sound outlet channel 112 to the auxiliary sound guide cavity 300, the resistance increases, hindering the smooth flow of the sound signal from the auxiliary sound guide cavity 300 and the auxiliary sound outlet hole 114. In another embodiment, the top wall of the auxiliary sound guide cavity 300 is flush with the top wall of the sound outlet channel 112. In this case, the flow area at the connection between the auxiliary sound guide cavity 300 and the sound outlet channel 112 is not smaller than the flow area of ​​the sound outlet channel 112. Therefore, as the sound signal flows from the sound outlet channel 112 to the auxiliary sound guide cavity 300, the resistance remains constant or decreases, which facilitates the smooth flow of the sound signal from the auxiliary sound guide cavity 300 and the auxiliary sound outlet hole 114. In addition, the smooth transition between the top wall of the auxiliary sound guide cavity 300 and the top wall of the sound outlet channel 112 can also reduce the resistance during the transmission of sound signals.

[0028] In an optional embodiment, the flow area at the end of the sound guide channel 111 connected to the sound outlet channel 112 is less than or equal to the flow area of ​​the sound outlet channel 112, or the flow area at the end of the sound guide channel 111 connected to the sound outlet channel 112 is greater than the flow area of ​​the sound outlet channel 112. In the latter embodiment, as the sound signal flows from the connection between the sound guide channel 111 and the sound outlet channel 112 to the sound outlet channel 112, the flow area decreases and the flow velocity of the sound signal increases. This facilitates the timely and primary outflow of the sound signal from the main sound outlet hole 113, and even when at least a portion of the main sound outlet hole 113 is blocked, the sound signal can also be timely outflowed from the auxiliary sound outlet hole 114.

[0029] In one optional embodiment, the device body 100 includes a frame 110, an auxiliary sound outlet 114 is formed in the frame 110, the extension direction of the sound outlet channel 112 is not consistent with the extension direction of the frame 110, the sound guide channel 111 is bent relative to the sound outlet channel 112, and the main sound outlet 113 extends to the sidewall of the sound outlet channel 112. In another embodiment, the sound outlet channel 112 extends along the extension direction of the frame 110. Thus, the frame 110 can have the sound outlet channel 112 formed along its own extension direction, which simplifies the manufacturing process. Furthermore, the sound outlet channel 112 does not occupy excessive space in the thickness direction of the frame 110, which is beneficial for achieving a thinner and lighter electronic device.

[0030] In an optional embodiment, the main sound outlet 113 can be a circular through hole, or the main sound outlet 113 can be a sound outlet slit, and the sound outlet channel 112 can be a strip-shaped sound outlet groove, with the sound outlet slit and the strip-shaped sound outlet groove facing each other and communicating. In this embodiment, both the strip-shaped sound outlet groove and the sound outlet slit are strip-shaped structures, which can increase the sound outlet area of ​​the main sound outlet 113 and ensure that the sound signal preferentially flows out from the sound outlet slit, thus facilitating the expansion of the sound output area of ​​the main sound outlet 113. Optionally, the extension direction of the strip-shaped sound outlet groove is consistent with the extension direction of the sound outlet slit, and the first end of the strip-shaped sound outlet groove faces the first end of the sound outlet slit, while the auxiliary sound guide cavity 300 faces the second end of the sound outlet slit. This maximizes the length of the sound outlet slit, further expanding the sound output area of ​​the main sound outlet 113.

[0031] In an optional embodiment, the device body 100 further includes a display module 120, which is disposed in the central region of the frame 110. The frame 110 is an integral structure, and the frame 110 has auxiliary sound holes 114 and sound gaps. The frame 110 also has a strip-shaped sound groove communicating with the sound gaps. In another embodiment, such as... Figure 1 As shown, the frame 110 has a split structure, including a first frame portion a and a second frame portion b. The display module 120 is disposed on the first frame portion a, and the auxiliary sound outlet 114 is disposed on the second frame portion b. A sound outlet gap is provided between the first frame portion a and the second frame portion b. After the first frame portion a and the second frame portion b are installed together, a strip-shaped sound outlet groove and a sound outlet gap are formed on the surface of the first frame portion a and the surface of the second frame portion b. In this way, by setting corresponding structures on the surfaces of the first frame portion a and the second frame portion b, the sound outlet gap and the strip-shaped sound outlet groove can be directly formed after the two are connected, eliminating the need to separately open the sound outlet gap and the strip-shaped sound outlet groove, which helps to reduce the process requirements.

[0032] In an optional embodiment, the frame 110 is provided with at least two auxiliary sound outlets 114 along its extension direction. The distance between the auxiliary sound outlet 114 closest to the main sound outlet 113 and the main sound outlet 113 in the extension direction of the frame 110 is greater than or equal to a preset value, indicating that the distance between the auxiliary sound outlet 114 and the main sound outlet 113 is relatively large. Alternatively, the distance between the auxiliary sound outlet 114 closest to the main sound outlet 113 and the main sound outlet 113 in the extension direction of the frame 110 is less than the preset value, indicating that the distance between the auxiliary sound outlet 114 and the main sound outlet 113 is relatively small, and the distance between the sound-emitting areas of the auxiliary sound outlet 114 and the main sound outlet 113 is also relatively small. In the latter embodiment, the electronic device is less prone to sound leakage, preventing sound from flowing to other sound-emitting areas and causing leakage when the main sound outlet 113 is blocked. Optionally, the preset value can be a value slightly greater than zero.

[0033] In an optional embodiment, the frame 110 is provided with at least two auxiliary sound outlets 114 along its extension direction. In the thickness direction of the electronic device, the orthographic projection of each auxiliary sound outlet 114 is outside the orthographic projection of the main sound outlet 113. In another embodiment, the orthographic projection of the main sound outlet 113 coincides with the orthographic projection of at least one auxiliary sound outlet 114. Optionally, the main sound outlet 113 is a sound outlet gap. In the thickness direction of the electronic device, the orthographic projection of the sound outlet gap coincides with at least a portion of the orthographic projection of at least one auxiliary sound outlet 114. Using this embodiment, in the thickness direction of the electronic device, the sound-emitting area of ​​the main sound outlet 113 at least partially coincides with the sound-emitting area formed by each auxiliary sound outlet 114. This indicates that the auxiliary sound outlets 114 are relatively close to the main sound outlet 113, making the electronic device less prone to sound leakage and preventing sound leakage from flowing to other areas when the main sound outlet 113 is blocked.

[0034] In a further embodiment, at least two auxiliary sound outlets 114 are located directly above or below the sound outlet gap, that is, in the thickness direction of the electronic device, the orthographic projection of the sound outlet gap coincides with the orthographic projection of each auxiliary sound outlet 114, thereby further preventing sound leakage.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
