Detailed Implementation

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0034] Unless otherwise stated, directional terms such as "upper," "lower," "left," and "right" are defined according to the directions indicated in the corresponding drawings, while "inner" and "outer" refer to the inner and outer contours of the corresponding component itself. Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not imply sequentiality or importance.

[0035] like Figures 1 to 14 As shown, this disclosure provides a housing assembly 1 for use in terminal devices, including but not limited to electronic devices such as mobile phones, laptops, and tablets. The housing assembly 1 is used to construct the overall outline of the terminal device and to house various electronic components, such as a speaker 2 for converting electrical energy into sound. The housing assembly 1 has an earpiece hole 123 and a speaker outlet hole. The earpiece hole 123 transmits sound to the user's ear during a call, while the speaker outlet hole is used to amplify sound from games or movies. Typically, the volume of the sound transmitted from the speaker outlet hole is greater than the volume of the earpiece hole 123.

[0036] In some embodiments of this disclosure, the sound outlet is a first sound outlet 1111 disposed at the top of the housing assembly 1, and / or a second sound outlet 1113 disposed at the bottom of the housing assembly 1. In other embodiments, sound outlets may be disposed at both the top and bottom of the housing assembly 1. This symmetrical arrangement of the first sound outlet 1111 and the second sound outlet 1113 creates a surround sound effect during the operation of the speaker 2.

[0037] For the consideration of layout space and other factors, the earpiece hole 123 and the sound outlet hole are communicated through the sound channel 1131 inside the shell assembly 1. When the shell assembly 1 is provided with the sound outlet hole at only one of the top or the bottom, the earpiece hole 123 is selectively provided at one of them or both of them correspondingly, which is not limited in the disclosure. In the design scheme that the earpiece hole 123 and the sound outlet hole are communicated through the sound channel 1131, it is easy to cause some sound to leak from the sound outlet hole during the call, which affects the privacy of the call.

[0038] To solve this problem, the shell assembly 1 of the disclosure further comprises a sound insulation piece 13 with a through hole 131, the sound insulation piece 13 is movably arranged on the shell assembly 1 so that the sound insulation piece 13 has a first position and a second position, wherein in the first position, the through hole 131 at least partially overlaps the normal projection of the sound outlet hole in the preset direction, and in the second position, the sound insulation piece 13 blocks the sound outlet hole. Wherein, the preset direction can be understood as the sound emission direction.

[0039] It should be noted that in the first position, the through hole 131 does not require the normal projection of the sound outlet hole in the preset direction to be completely overlapped (directly), and even if the two are partially staggered, as long as the sound channel can be communicated with the outside through the sound outlet hole.

[0040] To be more intuitive, the sound insulation piece 13 can play a role similar to a valve, which is used to open or close the sound outlet hole. For ease of description, the following will take the example of the earpiece hole 123 and the sound outlet hole being arranged on the top of the shell assembly 1. In the first position, the through hole 131 on the sound insulation piece 13 at least partially overlaps the normal projection of the first sound outlet hole 1111 in the preset direction, at this time, it is equivalent to opening the first sound outlet hole 1111, so that the sound channel 1131 is communicated with the outside, and the sound can be directly transmitted to the outside through the first sound outlet hole 1111, realizing the function of game or movie sound externalization. In the second position, the sound insulation piece 13 blocks the first sound outlet hole 1111, at this time, it is equivalent to closing the first sound outlet hole 1111, because the first sound outlet hole 1111 is closed, the sound flow can only change the flow direction, and is forced to be transmitted from the earpiece hole 123, so as to realize the purpose of private call.

[0041] The present disclosure does not limit the shape of the sound insulation piece 13 and the manner of movement, for example, in the form of a sheet or a block, and the sound insulation piece 13 can also be switched between the first position and the second position by sliding or rotating, which is not described herein. It should be noted that the sound insulation piece 13 can be arranged at the first sound outlet hole 1111 and / or the second sound outlet hole 1113. Specifically, when the sound outlet hole is arranged at only one of the top or the bottom, that is, the sound insulation piece 13 is correspondingly arranged at the position, if the sound outlet hole is arranged at both the top and the bottom, the sound insulation piece 13 can be optionally arranged at one of the positions or both positions correspondingly.

[0042] The technical scheme provided by the embodiment of the present disclosure can include the following beneficial effects: in the process of calling, by driving the sound insulation piece 13 to the second position to block the sound outlet hole, the sound flow can be forced to pass through the sound channel 1131 and be transmitted from the earpiece hole 123, without the problem of partial sound leakage from the sound outlet hole, ensuring the privacy of the call. When playing games or watching movies and the like require external sound, the user can drive the sound insulation piece 13 to the first position by a convenient operation, at this time, the sound can be directly transmitted outward through the sound outlet hole.

[0043] According to an embodiment of the present disclosure, with reference to Figures 1 to 9 The shell assembly 1 can include a middle frame 11 and a middle frame decoration 12. One side of the middle frame 11 is provided with a mounting portion 1122 for mounting the loudspeaker 2, and the other side of the middle frame 11 is formed with a recessed portion 1121 recessed towards the direction of the mounting portion 1122. Here, one side and the other side refer to the front and back sides of the middle frame 11. The loudspeaker 2 can be fixedly arranged on the mounting portion 1122 by pasting or fasteners. The recessed portion 1121 is provided with a through hole 11211 for the sound of the loudspeaker 2 to pass through, the middle frame decoration 12 is buckled on the middle frame 11 and forms a cavity 17 with the recessed portion 1121, and the cavity 17 is in communication with the sound channel 1131.

[0044] The sound emitted by the loudspeaker 2 enters the cavity 17 through the through hole 11211, and since the cavity 17 is in communication with the sound channel 1131, the sound enters the sound channel 1131 through the cavity 17, so as to be transmitted from the earpiece hole 123 or the first sound outlet hole 1111. In addition, the mounting portion 1122 for mounting the loudspeaker 2 and the recessed portion 1121 for forming the cavity 17 are respectively arranged on the two sides of the middle frame 11, so that various electronic components can be concentrated on the same side of the middle frame 11, and the other side is almost flat, saving space and facilitating the thin and light design of the terminal device.

[0045] Continuing to refer to Figures 1 to 3The middle frame 11 can be constructed to include a first frame 111 and a plate 112 filled inside the first frame 111, with a groove 113 extending parallel to the edge of the first frame 111 formed between the first frame 111 and the plate 112. The shape of the first frame 111 can be designed according to actual needs, for example, in Figure 1 In the illustrated embodiment, the first frame 111 is constructed to be approximately rectangular. The first frame 111, plate 112, and groove 113 can be an integral or separate structure. When the first frame 111, plate 112, and groove 113 are an integral structure, they can be formed into an integral structure by injection molding. The first sound outlet 1111 is located on the first frame 111, and the sound channel 1131 is formed on the groove 113. In the design of the middle frame 11, the groove 113 connects the first frame 111 and plate 112, so that the sound channel 1131 located on the groove 113 can serve to connect the cavity 17 and the first sound outlet 1111. The earpiece sound guide groove 1133, used to transmit sound outward from the earpiece hole 123, can be constructed as a further extension of the sound channel 1131 and formed on the groove 113.

[0046] As one way to realize the cavity 17, the recess 1121 can be constructed in a stepped shape. The middle frame decorative member 12 includes a second frame 121 and a blocking portion 122, the blocking portion 122 can be constructed in any suitable shape, in Figure 1 In the illustrated embodiment, the shielding portion 122 is constructed as a sheet or block. The second frame 121 is attached to the first frame 111 by adhesive 16. The shielding portion 122 is integrally formed on the second frame 121 and its shape matches the stepped surface of the recess 1121 to form a cavity 17 with the recess 1121. The shielding portion 122 is designed according to the size of the recess 1121; that is, compared to the middle frame 11, the middle frame decorative piece 12 does not necessarily have a complete plate body, but only needs to provide a smaller shielding portion 122 at the position corresponding to the recess 1121, so as to reduce the weight of the middle frame decorative piece 12 and facilitate the lightweight design of the terminal device. Figure 1 As shown, the earpiece hole 123 is located on the second frame 121, and its specific position corresponds to the earpiece sound guide groove 1133 located on the middle frame 11.

[0047] Furthermore, on both sides of the middle frame 11, the positions of the mounting portion 1122 and the recessed portion 1121 correspond to each other. In this way, the sound emitted by the speaker 2 can directly enter the cavity 17 through the through hole 11211 without having to travel a distance in the housing assembly 1 before entering the cavity 17 through the through hole 11211, thereby reducing unnecessary attenuation of the sound emitted by the speaker 2.

[0048] According to an embodiment of the present disclosure, as shown in Figures 10 to 12 The soundproof piece 13 can be configured in a sheet shape or a block shape, and the housing assembly 1 is provided with a sliding groove 1132, and the soundproof piece 13 is slidingly arranged in the sliding groove 1132 to switch the soundproof piece 13 between the first position and the second position. In space, the sliding groove 1132 is located between the sound channel 1131 and the first sound hole 1111, so as to open or close the passage of sound to the second sound hole 1113 via the sound channel 1131. In addition, the sliding groove 1132 can also play a guiding role to avoid affecting the shielding effect due to the deviation of the sliding track of the soundproof piece 13.

[0049] The driving of the soundproof piece 13 can be electric driving, for example, configured with a separate driving motor and a sensor. The sensor is used to monitor the working state of the terminal device, for example, whether the terminal device is in a private call state or a game state of external sound, so as to further control the switching of the soundproof piece 13 between the first position and the second position. Alternatively, the soundproof piece 13 can also be manually driven, for example, the housing assembly 1 can further include an operating piece 14, and the top of the housing assembly 1 is provided with an opening 1112 for sliding of the operating piece 14. The opening 1112 can be designed into any shape such as a strip shape, a square shape or a circular shape according to needs, which is not limited here. The operating piece 14 at least partially protrudes from the opening 1112, and the part of the operating piece 14 extending into the opening 1112 is used for fixed connection with the soundproof piece 13.

[0050] The operating piece 14 at least partially protrudes from the opening 1112, which is beneficial for the user to perform the dialing operation. In order to save the volume of the terminal device, the protruding part of the operating piece 14 can be as small as possible, and an anti-slip protruding rib can be arranged on the top surface of the operating piece 14. The part of the operating piece 14 extending into the opening 1112 is fixedly connected with the soundproof piece 13, so as to synchronously drive the soundproof piece 13 to slide in the process of dialing the operating piece 14.

[0051] The first sound hole 1111 is usually spaced apart in multiple numbers along the width direction of the terminal device, so that the extending direction of the opening 1112 can also be arranged along the width direction of the terminal device, and in addition, the movement direction of the soundproof piece 13 and the arrangement direction of the plurality of through holes 131 on the soundproof piece 13 are also arranged along the width direction of the terminal device.

[0052] The soundproof piece 13 can also be provided with a transmission hole 132, that is, the soundproof piece 13 is connected with the operating piece 14 through the transmission hole 132. It should be noted that the present disclosure does not limit the size and arrangement position of the transmission hole 132, for example, the transmission hole 132 can be arranged on the soundproof piece 13 in a position corresponding to the operating piece 14. Figure 2In the shown embodiment, the transmission hole 132 is arranged at a distance from the through holes 131, is further away than the distance between the through holes 131, and is also smaller in size than the through holes 131. In other possible embodiments, the distance between the transmission hole 132 and the adjacent through hole 131, and the size of the transmission hole 132 can be adjusted as needed, and the outermost through hole 131 can even be used directly as the transmission hole 132.

[0053] The part of the operating member 14 that extends into the opening 1112 is formed with a connecting portion for insertion into the transmission hole 132, which can be configured as a columnar shape matching the shape of the transmission hole 132, for example. The connecting portion inserted into the transmission hole 132 is fixedly connected with the sound insulation member 13 by cooperating with the elastic clamping member 15. For example, the elastic clamping member 15 can be a clamping spring, and the connecting portion is provided with a groove for cooperating with the clamping spring, which is clamped in the groove to avoid the connecting portion from being pulled out of the transmission hole 132 and to prevent the clamping spring from being pulled off the connecting portion due to excessive force. In other embodiments, the sound insulation member 13 and the operating member 14 can also be connected by other connection methods such as buckling, or can be fixedly connected by welding, for example.

[0054] The following exemplary describes a complete implementation of a housing assembly 1 according to the present disclosure, and still takes the example of the earpiece hole 123 and the sound outlet hole arranged at the top of the housing assembly 1. As shown in Figures 4 to 6 The sound insulation member 13 is in the first position, i.e., the through hole 131 at least partially overlaps the first sound outlet hole 1111 in the orthogonal projection in the preset direction. During gaming or movie watching, the sound emitted by the loudspeaker 2 enters the cavity 17 through the through hole 11211, and since the cavity 17 is in communication with the sound channel 1131, the sound in the cavity 17 can be transmitted out through the first sound outlet hole 1111. As shown in Figures 7 to 9 The sound insulation member 13 is in the second position, i.e., the through hole 131 blocks the first sound outlet hole 1111. During private conversation, the sound emitted by the loudspeaker 2 enters the cavity 17 through the through hole 11211, and then enters the sound channel 1131, at which time the sound is forced to be transmitted out through the earpiece hole 123 since the channel for transmitting the sound out through the first sound outlet hole 1111 is blocked by the sound insulation member 13.

[0055] A second object of the present disclosure is to provide a terminal device comprising the housing assembly 1 and the loudspeaker 2, the housing assembly 1 being any of the above-described embodiments and having all the beneficial effects thereof, which will not be repeated here.
