The following describes the implementation of the present invention in detail with reference to specific embodiments.

As shown in fig. 1-11, an embodiment of the present invention provides a mobile terminal, which includes: the middle of the top of the middle shell 1 (namely, the position of the sound outlet 11 of the mobile terminal such as a mobile phone in the prior art, which is located at the top of the mobile terminal and is the middle position) of the middle shell 1 is provided with a sound outlet 11, the middle shell 1 is provided with an installation groove 12, the bottom of the installation groove 12 is provided with a sound cavity groove 13, the side wall of the sound cavity groove 13 is provided with a first sound outlet notch 14, and the middle shell 1 is provided with a sound outlet channel 15 which is communicated with the first sound outlet notch 14 and the sound outlet 11; the flexible piece 2 is positioned in the mounting groove 12, the flexible piece 2 comprises a horizontal part 21 and a bending part 22, the horizontal part 21 is provided with a sound cavity hole 23, the side wall of the sound cavity hole 23 is provided with a second sound outlet notch 24 communicated with the first sound outlet notch 14, the horizontal part 21 is abutted with the bottom of the mounting groove 12 (so as to realize the sealing connection between the receiver 3 and the bottom of the mounting groove 12), and the bending part 22 is abutted with the side wall of the mounting groove 12 (so as to realize the sealing contact between the receiver 3 and the side wall of the mounting groove 12); the receiver 3 is disposed in the mounting groove 12, the sound emitting portion 31 of the receiver 3 corresponds to the sound cavity hole 23, the front surface of the receiver 3 abuts against the horizontal portion 21, and the side surface of the receiver 3 abuts against the bending portion 22 (at least one bending portion 22 may be provided, and when one bending portion 22 is provided, the position of the bending portion corresponds to the position of the second sound emitting gap 24, so as to prevent sound from leaking when the second sound emitting gap 24 transmits sound to the first sound emitting gap 14).

In the embodiment of the present invention, the sound emitted from the sound emitting portion 31 of the receiver 3 is transmitted to the sound cavity hole 23, and the second sound emitting notch 24 passing through the side wall of the sound cavity hole 23 is transmitted to the first sound emitting notch 14 of the side wall of the sound cavity groove 13, and then transmitted to the sound emitting hole 11 disposed in the middle of the top of the middle shell 1 through the sound emitting channel 15, so as to transmit the sound of the receiver 3 to the middle position of the top of the mobile terminal when the receiver 3 is not disposed in the middle of the mobile terminal.

Because the front surface of the receiver 3 is abutted (can be bonded) with the horizontal part 21, and the side surface of the receiver 3 is abutted (can be bonded) with the bending part 22, when the receiver 3 is tightly pressed and mounted in the mounting groove 12, the extrudable flexible part 2 deforms to seal the side walls and the bottom of the receiver 3 and the mounting groove 12, so that the sound emitted by the sound outlet part 31 of the receiver 3 can only enter the sound cavity hole 23, and is transmitted to the first sound outlet notch 14 of the side wall of the sound cavity groove 13 through the second sound outlet notch 24 of the side wall of the sound cavity hole 23, and is transmitted to the sound outlet hole 11 arranged in the middle of the top of the middle shell 1 through the sound outlet channel 15 to be transmitted outwards, thereby ensuring the sealing effect in the sound transmission process and further realizing a better sound guiding effect.

The inventor has found a way to transmit sound to the middle of a mobile terminal by making the receiver 3 as a plastic case assembly, sealing the receiver 3 with a plastic case to form a sound chamber; two dies of an upper cover and a lower cover of the box are required to be opened, the upper cover and the lower cover are sealed by ultrasonic waves, and a switching flexible circuit board is assembled on the box to connect the receiver 3 and the main board. The cost is increased, the assembly process is increased, and a large space is occupied. The defective rate of the flexible circuit board is increased in a small case of the receiver 3.

The inventor also finds a way to transmit sound to the middle of the mobile terminal by adding a plastic support 8 and attaching foam to combine with the surrounding bone on the body case and compress it to form a cavity seal. And then leads the sound to the front. When the sound is guided to the front, the sound outlet hole is far away from the center. And the plastic support 8 and the machine body shell are sealed through foam, and except that the requirements on the flatness and the strength of the plastic support and the machine body shell are met, the peripheries of the plastic support and the machine body shell are locked through a plurality of groups of buckling positions or a plurality of screws, otherwise, the risk of poor sealing is caused. The occupied space is large, and the difficulty in designing a plurality of groups of buckling positions or screw columns in a very small space is very high. The sound outlet hole is far away from the center, so that the sound is reduced, and the use is influenced.

Further, referring to fig. 3, as another embodiment of the mobile terminal provided by the present invention, at least one side wall of the mounting groove 12 has an assembly inclined plane 121, and a vertical plane 122 is provided between the assembly inclined plane 121 and the bottom of the mounting groove 12. During assembly, the receiver 3 and the flexible element 2 can be bonded and then integrally placed in the mounting groove 12, and the assembly inclined plane 121 is arranged, so that the receiver 3 and the flexible element 2 can be integrally and smoothly inserted into the mounting groove 12 and tightly contacted with the bottom and the side wall of the mounting groove 12.

Because the internal diameter of the first sound emitting section 111 is greater than the internal diameter of the second sound emitting section 112, and the internal diameter of the second sound emitting section 112 is greater than the internal diameter of the third sound emitting section 113, the thickness of the position of the middle shell 1 where the sound emitting hole 11 is formed is gradually reduced, and the position beside the sound emitting hole 11 is used for installing the camera 100 of the mobile terminal, so that the periphery of the camera 100 is not broken, and the camera 100 can be installed well.
