As shown in fig. 1 to 14, the present disclosure provides a housing assembly 1 applied to a terminal device, including but not limited to electronic devices such as a mobile phone, a notebook computer, and a tablet computer. The housing assembly 1 is used to construct the overall outline of the terminal device and to house and mount various electronic components, such as a speaker 2 for converting electrical energy into sound. The housing assembly 1 is provided with a receiver hole 123 and a sound outlet hole of a loudspeaker, the receiver hole 123 is used for transmitting sound to ears of a user during conversation, and the sound outlet hole 1111 is used for playing sound such as games or movies. Typically, the volume of sound transmitted from the sound outlet is greater than the volume of the earpiece hole 123.

In some embodiments of the present disclosure, the sound outlet is a first sound outlet 1111 provided at the top of the housing assembly 1, and/or a second sound outlet 1113 provided at the bottom of the housing assembly 1. In other embodiments, sound outlets may be provided at both the top and bottom of the housing assembly 1, with the first and second sound outlets 1111, 1113 being symmetrically arranged up and down so as to create a surround sound effect during operation of the speaker 2.

The earpiece hole 123 and the sound outlet hole communicate through the acoustic channel 1131 inside the housing assembly 1, in consideration of layout space and the like. When the housing assembly 1 is provided with the sound outlet hole at only one of the top or bottom, i.e., the earpiece hole 123 is correspondingly provided therein, if the sound outlet hole is provided at both the top or the top, the earpiece hole 123 may be selectively provided at one of them or the earpiece hole 123 is correspondingly provided at both places, which is not limited in the present disclosure. Under such a design scheme that the earpiece hole 123 is communicated with the sound outlet through the sound channel 1131, a part of sound is likely to leak out from the sound outlet in the process of talking, so as to affect the privacy of talking.

To solve this problem, the housing assembly 1 of the present disclosure further includes a sound insulating member 13 having a through hole 131, and the sound insulating member 13 is movably disposed on the housing assembly 1 such that the sound insulating member 13 has a first position in which the through hole 131 at least partially overlaps with an orthographic projection of the sound outlet in a predetermined direction, and a second position in which the sound insulating member 13 shields the sound outlet. The preset direction can be understood as the sound emitting direction.

In the first position, the orthographic projections of the through hole 131 and the sound outlet in the predetermined direction are not required to be completely overlapped (aligned), and even if the through hole and the sound outlet are partially offset, the through hole and the sound outlet can be communicated with the outside.

Visually, the sound insulating member 13 can function like a valve for opening or closing the sound outlet. For convenience of description, the following will be exemplified by taking an example in which the earpiece hole 123 and the sound outlet hole are provided at the top of the housing assembly 1. In the first position, the through hole 131 on the sound insulation member 13 at least partially overlaps with the orthographic projection of the first sound outlet 1111 in the preset direction, which is equivalent to opening the first sound outlet 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 1111, so as to realize the function of playing or playing a movie. In the second position, the sound insulating member 13 shields the first sound outlet 1111, and at this time, the first sound outlet 1111 is closed, so that the sound airflow can only change its direction and is forcedly sent out from the receiver hole 123, thereby achieving the purpose of private communication.

The shape and movement of the sound insulating member 13 are not limited by the present disclosure, for example, the sound insulating member 13 may be a sheet or a block, and the sound insulating member 13 may be switched between a first position and a second position by sliding or rotating, which will not be described herein. It should be noted that the sound insulating member 13 may be disposed at the first sound outlet 1111 and/or the second sound outlet 1113. Specifically, when the sound outlet holes are provided at only one of the top or bottom, that is, the sound insulating member 13 is provided correspondingly thereto, if the sound outlet holes are provided at both the top or the top, the sound insulating member 13 may be provided selectively at one of them or at both of them correspondingly.

The technical scheme provided by the embodiment of the disclosure can comprise the following beneficial effects: in the process of talking, the sound insulating member 13 is driven to the second position to shield the sound outlet, so that the sound air can be forced to pass through the sound channel 1131 and be transmitted out of the receiver hole 123, the problem that part of sound leaks out of the sound outlet is avoided, and the privacy of talking is ensured. When the user drives the sound insulating member 13 to the first position through a convenient operation in a scene where the sound is required to be externally emitted, such as a game or a movie, the sound can be directly externally emitted through the sound emitting hole.

According to one embodiment of the present disclosure, referring simultaneously to fig. 1-9, the housing assembly 1 may include a center 11 and a center trim 12. A mounting portion 1122 for mounting the speaker 2 is provided on one side of the center frame 11, and a recess 1121 recessed toward the mounting portion 1122 is formed on the other side of the center frame 11. Here, one side and the other side refer to both the front and the back sides of the middle frame 11. The speaker 2 may be fixedly attached to the mounting portion 1122 by adhesion or a fastener. The recess 1121 is provided with a through hole 11211 through which the sound of the speaker 2 penetrates, and the middle frame decoration 12 is fastened to the middle frame 11 and forms a cavity 17 with the recess 1121, and the cavity 17 is communicated with the channel 1131.

Sound emitted from the speaker 2 enters the cavity 17 through the through hole 11211, and since the cavity 17 communicates with the acoustic channel 1131, the sound enters the acoustic channel 1131 through the cavity 17 so as to be emitted from the earpiece hole 123 or the first sound emission hole 1111. In addition, the mounting portion 1122 for mounting the speaker 2 and the recess 1121 for forming the cavity 17 are respectively located on both 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 nearly flat plate-shaped, saving space, and facilitating the light and thin design of the terminal device.

With continued reference to fig. 1 to 3, the middle frame 11 may be configured to include a first frame 111 and a plate 112 filled inside the first frame 111, with a groove 113 extending parallel to an edge of the frame 111 formed between the first frame 111 and the plate 112. The shape of the first frame 111 may be designed according to actual needs, for example, in the embodiment shown in fig. 1, the first frame 111 is configured to be substantially rectangular. The first frame 111, the plate 112 and the groove 113 may be in an integral structure or a split structure, and when the first frame 111, the plate 112 and the groove 113 are in an integral structure, the first frame 111, the plate 112 and the groove 113 may be formed into an integral structure by injection molding. The first sound outlet 1111 is disposed on the first housing 111, and the sound channel 1131 is disposed on the groove 113. In the design of the middle frame 11, the groove 113 is connected between the first frame 111 and the board 112, so that the sound channel 1131 provided on the groove 113 can function as the communication cavity 17 and the first sound outlet 1111. An earpiece sound guide channel 1133 for transmitting sound outwardly from the earpiece hole 123 may be formed on the channel 113 as part of the continued extension of the acoustic channel 1131.

As one way of realizing the cavity 17, the recess 1121 may be configured in a stepped shape. The middle frame garnish 12 includes a second frame body 121 and a shielding portion 122, and the shielding portion 122 may be configured in any suitable shape, and in the embodiment shown in fig. 1, the shielding portion 122 is configured in a sheet-like or block-like structure. The second frame 121 is attached to the first frame 111 by the back adhesive 16. The shielding portion 122 is integrally formed on the second frame body 121 and has a shape matching the step surface of the recess portion 1121 for forming the cavity 17 with the recess portion 1121. The shielding part 122 is designed according to the size of the recess 1121, that is, compared with the middle frame 11, the middle frame decoration 12 does not necessarily have a complete plate body, but only the shielding part 122 with smaller size is required to be arranged at the position corresponding to the recess 1121, so that the weight of the middle frame decoration 12 can be reduced, and the lightweight design of the terminal equipment is facilitated. As shown in fig. 1, the earpiece hole 123 is provided on the second frame body 121 in a specific position corresponding to the earpiece sound guide groove 1133 provided on the center frame 11.

Further, on both side surfaces of the middle frame 11, the position of the mounting portion 1122 corresponds to the position of the recessed portion 1121. In this way, sound emitted by the loudspeaker 2 can enter the cavity 17 directly through the through-holes 11211 without having to enter the cavity 17 through the through-holes 11211 after having been transmitted a distance in the housing assembly 1, thereby reducing unnecessary attenuation of sound emitted by the loudspeaker 2.

According to one embodiment of the present disclosure, as shown in fig. 10 to 12, the soundproof member 13 may be configured in a sheet or block shape, the inside of the housing assembly 1 is provided with a sliding groove 1132, and the soundproof member 13 is slidably provided in the sliding groove 1132 so that the soundproof member 13 is slidably switched between the first position and the second position. Spatially, the chute 1132 is located between the channel 1131 and the first sound outlet 1111, thereby opening or closing the passage of sound through the channel 1131 to the second sound outlet 1111. In addition, the chute 1132 can also play a role of guiding, and the effect of shielding is prevented from being influenced by deviation of the sliding track of the sound insulation member 13.

The soundproof member 13 may be driven electrically, for example, by being provided with a separate driving motor and sensor. The sensor is used for monitoring the working state of the terminal equipment, such as whether the terminal equipment is in a private call state or a state of playing the external sound, and the like, so as to further control the sound insulation piece 13 to switch between the first position and the second position. Alternatively, the sound insulating member 13 may be manually driven, for example, the housing assembly 1 may further include an operating member 14, the top of the housing assembly 1 is provided with an opening 1112 for sliding the operating member 14, and the opening 1112 may be designed into any shape such as a bar shape, a square shape, or a circular shape, as needed, which is not limited herein. The operating member 14 protrudes at least partially from the opening 1112, and a portion of the operating member 14 protruding into the opening 1112 is for fixed connection with the sound insulating member 13.

The operating member 14 at least partially protrudes through the opening 1112 to facilitate a user's toggle operation. To save volume of the terminal device, the protruding portion of the operating member 14 may be as small as possible, and an anti-slip rib may be provided on the top surface of the operating member 14. The portion of the operating member 14 extending into the opening 1112 is fixedly connected to the sound insulating member 13 so that the sound insulating member 13 is synchronously driven to slide during the pulling of the operating member 14.

The first sound outlet holes 1111 are generally provided in plural at intervals in the width direction of the terminal device, and thus, the extending direction of the opening 1112 may also be provided in the width direction of the terminal device, and furthermore, the moving direction of the sound insulating member 13 and the arrangement direction of the plural through holes 131 on the sound insulating member 13 may also be provided in the width direction of the terminal device.

The sound insulating member 13 may be further provided with a transmission hole 132, that is, the sound insulating member 13 is connected to the operating member 14 by providing the transmission hole 132. It should be noted that the size and arrangement position of the transmission hole 132 are not limited by the present disclosure, for example, in the embodiment shown in fig. 2, the transmission hole 132 is spaced from the through holes 131, and the transmission hole 132 is spaced farther than the plurality of 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 one of the through holes 131 may be adjusted as needed, and the size of the transmission hole 132 may even be used as the transmission hole 132 directly with the outermost one of the through holes 131.

The portion of the operating member 14 that protrudes into the opening 1112 is formed with a connecting portion for insertion into the drive aperture 132, for example, the connecting portion may be configured as a cylinder that matches the shape of the drive aperture 132. The connection portion inserted into the transmission hole 132 is fixedly connected to the operating member 14 and the soundproof member 13 by being engaged with the elastic clamping member 15. For example, the elastic clamping member 15 may be a clamping spring, and the connecting portion is provided with a groove for matching with the clamping spring, so that the clamping spring is locked in the groove to prevent the connecting portion from being separated from the transmission hole 132, and to prevent the clamping spring from slipping off the connecting portion due to excessive force. In other embodiments, the sound insulation member 13 and the operation member 14 may be connected by a snap, or the sound insulation member 13 and the operation member 14 may be directly and fixedly connected by welding.

A housing assembly 1 that may be fully implemented in accordance with the present disclosure is exemplarily described below, and still exemplifies that the earpiece hole 123 and the sound outlet hole are provided at the top of the housing assembly 1. As shown in fig. 4 to 6, the soundproof member 13 is in the first position, i.e., the through hole 131 is at least partially overlapped with the orthographic projection of the first sound outlet 1111 in the preset direction. When playing a game or watching a movie, sound emitted from the speaker 2 enters the cavity 17 through the through hole 11211, and since the cavity 17 communicates with the channel 1131, sound in the cavity 17 can be emitted through the first sound emitting hole 1111. As shown in fig. 7 to 9, the soundproof member 13 is shifted to the second position, that is, the through hole 131 shields the first sound outlet hole 1111. In the private call, the sound emitted from the speaker 2 enters the cavity 17 through the through hole 11211 and then enters the sound channel 1131, and at this time, the channel from the first sound outlet 1111 is blocked by the sound insulating member 13, and only forced to be emitted from the earpiece hole 123.

A second object of the present disclosure is to provide a terminal device, which includes a housing assembly 1 and a speaker 2, where the housing assembly 1 is a housing assembly described in any of the foregoing embodiments, and has all the beneficial effects thereof, which are not described herein.

Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure.
