Example 1

As shown in fig. 1, the present embodiment provides a mobile terminal including a middle frame structure, a speaker 100, and a screen 200. The middle frame structure comprises a middle frame body 300 and a side sound-emitting loudspeaker support 400, and the loudspeaker 100 is connected to the middle frame body 300 through being connected to the side sound-emitting loudspeaker support 400. The middle frame body 300 serves as a middle frame of the mobile terminal for mounting and carrying other components of the mobile terminal. The screen 200 is attached to the inner edge of the middle frame, and a speaker gap 210 is formed between a part of the screen 200, such as the top or the bottom of the screen 200, and the middle frame body 300, and serves as a speaker hole of the speaker 100 built in the screen, so as to transmit the sound of the speaker 100.

Referring to fig. 2 to 5, the side sound-emitting speaker stand 400 includes a stand body 410, and a mounting portion 411 and a sound outlet 412 are formed on the stand body 410. The mounting position 411 is formed on the inner side of the bracket body 410, and is used for mounting the speaker 100, and a diaphragm of the speaker 100 is opposite to the front inner side of the bracket body 410 and leaves a sound outlet gap 413. The sound outlet 412 is disposed on a side surface of the holder body 410 and is communicated with the sound outlet gap 413.

As described above, the front surface of the bracket body 410 is opposite to the screen 200, and the side surface of the bracket body 410 is a surface forming a certain included angle with the screen 200, and the included angle may be 90 ° or other angles. The outer side of the stand body 410 is a side facing the screen 200, and the inner side of the stand body 410 is a side facing away from the screen 200. The speaker 100 is installed inside the stand body 410 so that the diaphragm thereof is disposed toward the screen 200, and the diaphragm of the speaker 100 and the front stand form a sound outlet gap 413, so that the sound of the diaphragm can be transmitted to the sound outlet 412 located on the side and can be emitted from the sound outlet 412. This side play sound speaker support 400 sets up the sound outlet 412 of speaker 100 and has replaced traditional front play sound on the side, the required clearance of reserving between side play sound speaker support 400 and the center when having saved front play sound, directly goes out the sound at the side, can simplify effectively from this and send out the sound route, reduce the length of route of raising the sound, shared space when reducing speaker 100 and installing reduces the equipment degree of difficulty, thereby reduce speaker 100's distortion and optimize speaker 100's the effect of raising the sound.

In this embodiment, the side sound outlet speaker bracket 400 further includes a dust screen 420, and the dust screen 420 is connected to the bracket body 410 and used for shielding the sound outlet 412. The dust screen 420 can make sound propagate out in time on one hand, and on the other hand can effectively prevent dust from entering/flowing into the host machine to which the side sound output speaker bracket 400 is applied, thereby avoiding the problems of influencing the working environment of electrical components in the host machine, dissipating heat and even causing short circuit.

Further, the dust screen 420 has a first surface 421 and a second surface 422 bent relative to the first surface 421, the first surface 421 is connected to the outer side of the front surface of the bracket body 410, and the second surface 422 is connected to the outer side of the side surface of the bracket body 410. The bending intersection line of the first surface 421 and the second surface 422 forms a support rib of the dust-proof net 420, which can enhance the bending strength, prevent the dust-proof net 420 from collapsing (compared with the arc-shaped bending) at the bending position after being connected to the bracket body 410, and ensure the height of the diaphragm of the loudspeaker 100 at the bending position of the sound outlet. The support rib formed by the bending of the folded angle can be adjusted or eliminated according to the size of the loudspeaker 100. The connection between the dust screen 420 and the bracket body 410 may be by adhesive bonding.

In this embodiment, the bracket body 410 includes a plastic frame 410a and a metal plate 410b, the plastic frame 410a forms a side surface of the bracket body 410 and has a mounting position 411, and the metal plate 410b is connected to an open surface of the plastic frame 410a to form a front surface of the bracket body 410. The plastic frame 410a is formed by injection molding on the basis of the metal sheet 410b, so that the metal sheet 410b and the plastic frame 410a are connected by injection molding, and the sound outlet 412 is directly formed between the plastic frame 410a and the metal sheet 410b after injection molding. Further, the sound outlet 412 is strip-shaped, and the middle part of the sound outlet 412 is provided with a reinforcing rib, so that the sound outlet 412 is divided into two parts, thereby enhancing the connection structure between the plastic frame 410a and the metal sheet 410b, and effectively reducing/inhibiting the flexible deformation of the metal sheet 410 b. It will be appreciated that depending on the strength of the sheet metal 410b and the length of the suspension beam, no reinforcing ribs or a greater number of reinforcing ribs may be provided.

The metal sheet 410b may be, but is not limited to, a steel sheet, an iron sheet, or a stainless steel sheet. By molding the metal sheet 410b into the bracket body 410, the dimension of the bracket body 410 in the thickness direction can be reduced, so that the speaker 100 is closer to the screen 200. Of course, the bracket body 410 can also be an integral component supported by plastic.

The mounting location 411 is a step disposed in the plastic frame 410a, and the step is used for abutting against the end surface of the speaker 100, so that a sound gap 413 is formed between the diaphragm of the speaker 100 and the metal sheet 410 b. Therefore, the mounting position 411 enables the speaker 100 to directly form a sound outlet gap 413 with the metal sheet 410b when being mounted on the bracket body 410, so as to ensure the height of the diaphragm.

The bracket body 410 may be provided with a mounting portion 414, such as a mounting hole, for fixing the side-out speaker bracket 400, and the mounting portion may be screwed or pinned to a host computer to which the mounting portion is applied by screws, so as to form a pre-fixing for facilitating subsequent further mounting. The mounting portion 414 may also be a mounting clip, and the bracket body 410 is pre-fixed by a snap.

The side out-tone speaker bracket 400 further includes a sealing ring 430, and the sealing ring 430 is disposed on the end surface of the bracket body 410 and matches with the contour of the bracket body 410. Sealing washer 430 is cyclic annular, can be the rubber circle to its soft yielding characteristic makes support body 410 can form good end face seal when installing on other parts, forms sealed sound chamber, optimizes the effect of raising one's voice on the one hand, and on the other hand because sound chamber and external intercommunication can prevent outside dust, liquid from entering to the host computer that the sound speaker support 400 was used out to the side through forming confined sound chamber effectively.

The sealing ring 430 is connected to the stent body 410 by an adhesive, which may be glue, and is coated and filled between the stent body 410 and the sealing ring 430 to fix the sealing ring 430 on the stent body 410, or a double-sided adhesive, which is connected to the stent body 410 and the sealing ring 430 by two sides respectively to connect the two. In order to allow the sealing ring 430 to have a relatively stable installation form and position on the holder body 410, a corresponding annular groove may be provided on the holder body 410 for installing the sealing ring 430.

In other embodiments, the sealing ring 430 may be injection molded on the bracket body 410. The bracket body 410 may be made of hard plastic, such as PC, PPS, PVC, etc., and the sealing ring 430 may be made of soft plastic, such as fluororubber, silicone rubber, etc., which are made of different materials, and the sealing ring 430 is directly formed on the bracket body 410 by two-shot molding through a two-color mold.

Referring to fig. 6 to 7, when the side sound-emitting speaker stand 400 is applied to the middle frame structure, the stand body 410 is connected to the middle frame body 300 and forms a curved surface fit with the middle frame body 300.
