1a shows the structure of a related art mobile terminal including the following functions: an earpiece 11, a front camera 12, a distance sensor/ambient light sensor 13, a front flash 14, and an indicator light 15. The functional devices are located on the top of the mobile terminal 1 and are arranged along the width direction of the mobile terminal (W direction in Fig. 1a). These functional devices take up space on the screen, making the screen of the mobile terminal smaller.

In order to improve the problem that the screen of the mobile terminal shown in FIG. 1a is relatively small, FIG. 1b shows the structure of the mobile terminal having the Notch screen (profiled cutting screen) in the related art, that is, a slot is formed at the top of the mobile terminal toward the screen. The port 16 and the left and right sides of the notch 16 are display areas. The notch 16 is provided with functional components such as the earpiece 11, the distance sensor/ambient light sensor 13, and the space in which the pre-function device is originally placed is compressed. As a result, the screen share of mobile terminals has increased. On this basis, in order to further increase the screen ratio of the mobile terminal, for example, for the Notch screen, the width of the display area on the left and right sides of the slot can be increased. However, in this way, the width of the notch itself will become narrow, so that the arrangement of the functional devices can not be satisfied only by conventional techniques such as reducing the size of the functional device and reducing the spacing between the functional devices.

Therefore, in order to further reduce the size of the screen occupied by the functional device, some embodiments of the present disclosure set a functional device that partially occupies the position of the screen to the inside of the mobile terminal, thereby giving more space to the screen display area and increasing the screen ratio. At the same time, it also meets the functional requirements of the functional device itself. For example, the earpiece is placed inside the mobile terminal while the sound emitted by the earpiece is transmitted to the outside of the mobile terminal as much as possible.

Since the earpiece 241 is located in the accommodating space 23, the sound emitting surface 2411 of the earpiece 241 is in communication with the accommodating space 23, and the sound emitted by the earpiece 241 is propagated in any direction in the accommodating space 23, so that the sound emitted by the earpiece 241 cannot be clearly seen by the user. Hear it. Therefore, it is necessary to provide the spacer 25 in the direction of the sound emitting surface of the earpiece 241 to isolate the sound path of the earpiece 241 from the accommodating space 23. The partitioning member 25 covers the sound emitting surface of the earpiece 25 and has a passage with the sound emitting mask of the earpiece 241. The partitioning member 25 defines an opening, and the passage and the opening communicate with each other to form a sound guiding passage of the earpiece. The sound guiding channel transmits the sound emitted by the earpiece to the outside of the earpiece. The mobile terminal 2 also includes a screen 27 located on a side of the spacer that faces away from the sound emitting surface of the earpiece.

In some embodiments, as shown in FIGS. 3-4, the spacer 25 includes a base 253 that covers the exit surface of the earpiece 241, a side wall 254 that extends from the base 253 toward the side of the earpiece 241, and a base. The seat 253 is a carrying portion 255 extending toward the center of the sound emitting surface of the earpiece 241. The side wall 254 is in close contact with the side of the earpiece 241; the base 253 and the carrying portion 255 and the sound emitting surface have a passage 251; between the carrying portion 255 and the base 253 An opening 252 is provided, the opening 252 being capable of communicating with an exterior of the mobile terminal, the passage 251 communicating with the opening 252 to form a sound guiding passage of the earpiece, and the sound emitted by the earpiece is sequentially transmitted to the terminal through the passage 251 and the opening 252 external. Wherein, the base 253, the side wall 254 and the bearing portion 255 are integrally formed rigid plastic.

In some embodiments, a spacer of another configuration is provided. As shown in FIG. 6, the spacer 25 includes a base 653 covering the sound emitting surface 2411 of the earpiece 241, a side wall 654 extending from the base 653 toward the side of the earpiece 241, and a bearing covered on the base 653. In the portion 655, the carrying portion 655 can cover the sound emitting surface 2411 of the earpiece 241, and has a certain passage 651 with the sound emitting surface 2411 of the earpiece 241, and a gap exists between the carrying portion 655 and the base 653. 656, the channel can communicate with the outside of the mobile terminal through the gap 656, the channel 651 and the gap 656 communicate to form a sound guiding channel of the earpiece, and the sound of the earpiece passes through the channel 651 and the gap 656 in sequence. Passed to the outside of the terminal. Wherein the base 653 and the side wall 654 are integrally formed pieces, and the bearing portion 655 is a separate component from the base 653 and the side wall 654. The bearing portion 655 can be made of a hard material, for example, a conductive reinforcing plate, a flexible printed circuit (FPC) reinforcing plate, and the other part of the spacer (integral molded piece) can be made of silicone. For example, the base and the side walls are made of soft silicone to provide superior isolation.

In some embodiments, the mobile terminal further includes an electronic component that provides various functions for the user, such as a distance sensor that prevents the screen from being triggered by mistake when the call is made, and a light sensor that senses ambient light to adjust the brightness of the screen, for photographing the image before. Set the camera, the flash that fills the light in a dim light environment, the indicator light when charging or receiving a notification, and so on. Since the earpiece has become a standard for mobile terminals, and the earpiece is limited by its structure, its size is larger than that of electronic components (such as light/distance sensors, flashlights, etc.). Therefore, the earpiece 241 is placed in the accommodating space 23 so as not to occupy the screen, and the display area of the screen is increased. In order to facilitate the use of these electronic components, the electronic components of the related art are generally disposed near the side that the user often faces. The electronic component includes a first function 242 and a second functional device 243. The first functional device 242 can be one or more of a flash, a light sensor, a distance sensor, and an indicator light. The second functional device 243 can be a camera. The electronic components are arranged in the thickness direction of the mobile terminal.

In some embodiments, as shown in FIGS. 3-4, the first functional device 242 is located on a side of the carrier 25 of the spacer 25 that faces away from the ear exit surface of the earpiece, and the earpiece 241 and the first functional device 242 are superimposed along the thickness of the mobile terminal. Arrangement (H direction of FIG. 3), that is, the projection of the first functional device 241 in the direction of the sound emitting surface of the earpiece 241 is located in the earpiece 241, so that the arrangement of the functional device is more compact and does not affect the pendulum of other components of the mobile terminal. put. In the case where the earpiece 241 and the first functional device 242 are placed in the thickness direction of the mobile terminal, if there are still other electronic components that cannot be superimposed with the earpiece (for example, the first functional device is disposed above the earpiece), the first functional device may be A second functional device 243 is disposed adjacent to the first functional device and the second functional device. The first functional device 242 is superimposed on the larger size earpiece 241 to provide a larger display area for the screen. Especially in a mobile terminal having a Notch screen, the slot width can be made narrower, so that the screen ratio of the mobile terminal is higher. At the same time, the spacer 25 can prevent the sound from propagating to the accommodating space 23 of the mobile terminal, and the sound constraint from the earpiece is conducted to the outside of the mobile terminal for the user to clearly hear.

In some embodiments, as shown in FIG. 6, when the spacer is a conductive reinforcing plate, the first functional device 242 can be directly connected to the FPC reinforcing plate and electrically connected to the main PCB through the FPC (Printed Circuit) Board, printed circuit board).

In some embodiments, as shown in FIG. 3 and FIG. 6, the mobile terminal further includes a second housing 22 for fixing the electronic component and the spacer in the accommodating space 23. . Taking the mobile phone as an example, the side that the user often faces is referred to as a second housing 22, the second housing 22 is provided with a screen, and the side away from the screen is the first housing 21. Of course, the present disclosure is not limited thereto. For a dual-screen mobile phone, both sides of the mobile phone are used toward the user. In this case, either side may be the first housing, and the side opposite to the first housing is the second housing. .

In some embodiments, as shown in FIG. 2 and FIG. 3, the second housing 22 is provided with a first window 221, a through hole 222 and a second window 223, and the first window 221 and the second window 223 are in the second housing. 22 is arranged closely, the first functional device 242 is located in the first window 221, and the second functional device 243 (for example, a camera) is embedded in the second window 223. The through hole 222 is configured as a sound hole of the mobile terminal, and one end of the through hole 222 is communicated with the outside of the mobile terminal, and the other end of the through hole 222 is in communication with the earpiece sound guiding channel. The sound channel is used to constrain the sound emitted by the earpiece, and the sound emitted by the earpiece is turned on to the outside of the mobile terminal 2. When the user answers the call, the sound of the earpiece can be clearly heard. The area occupied by the through hole 222 disposed on the second housing 22 is smaller than the area occupied by the earpiece directly embedded in the second housing, thereby increasing the area of the screen display area. When the first functional device 242 includes at least two electronic components, the first window 221 of the second housing is one, that is, at least two first functional devices 242 are collectively disposed in the same window. This can reduce the arrangement space between the first functional devices. Of course, it is also possible to open a window for each of the first functional devices, that is, the number of the first windows corresponds to the number of the first functional devices.

It should be noted that the first functional device 242 of the present embodiment is superimposed with the earpiece 241 so that the first functional device is embedded in the second casing 22, and the earpiece 241 is disposed in the receiving space 23, so that the first functional device 241 is disposed. It is placed closer to the screen of the mobile terminal 2 because the function components such as the flash lamp and the sensor need to directly accept the external input signal or directly output the signal to the user due to its working principle. The sound has a characteristic of being transmitted in the air and can be located in the accommodating space 23.

In some embodiments, as shown in FIG. 6, a gap 26 is disposed between the first housing 21 and the second housing 22, and the slit 26 is configured as a sounding passage of the mobile terminal. A passage 651 formed between the earpiece 241 and the sound emitting surface 2411 and a sound guiding passage formed by a gap 656 between the bearing portion 655 and the base 653 communicate with the slit 26 to derive the sound emitted by the earpiece to Outside the mobile terminal. The gap 26 may be a gap formed naturally when the first housing 21 and the second housing 22 are installed, and need not be separately opened.

In some embodiments of the present disclosure, the handset does not occupy the space of the screen, so that the screen has a larger display area. The sound can be prevented from propagating into the accommodating space of the mobile terminal by the spacer, and the spacer also functions to carry and electrically connect with the first functional device, and the bearing portion and the other portions of the spacer are separately arranged, so that each of the spacers Some parts can be made of different materials to better play their respective roles.
