Referring to fig. 1-3, a glass cover plate assembly 100 is provided for use in an electronic device 200. The glass cover plate assembly 100 and the electronic device 200 provided in the present application will be explained below with reference to the accompanying drawings by way of examples. The electronic device 200 provided by the application can be a mobile phone, an IPad, an intelligent wearable device, a digital audio and video player, an electronic reader, a handheld game machine, a vehicle-mounted electronic device and other devices which need to make sound. The electronic device 200 includes a glass cover plate assembly 100 as taught in the following embodiments. As shown in fig. 3, the glass cover assembly 100 includes a housing 10, a glass cover 20 covering the housing 10, a receiver assembly 30 disposed on a side of the housing 10 opposite to the glass cover 20, and a back case 40 connected to the housing 10.

Referring to fig. 4 and 5, fig. 4 is a schematic structural view of the housing 10 with the glass cover 20 and the receiver assembly 30 removed, and fig. 5 is a partial enlarged view of a circle a in fig. 3. Specifically, the housing 10 is a supporting carrier of the electronic device 200, and is used for carrying the display screen 50, a printed circuit board (not shown), other devices, and the like. Specifically, a groove 12 is formed in the housing 10, the display screen 50 is disposed in the groove 12, and the glass cover plate 20 covers the display screen 50 and the housing 10. In various embodiments, the housing 10 may be a middle frame or a battery cover of the electronic device 200, which is not particularly limited. The side surface of the housing 10 has a portion exposed outside the electronic device 200 as a portion of the outer surface of the electronic device 200.

Specifically, the display screen 50 is a display interface of the electronic device 200, and is used for displaying pictures such as pictures and videos. The glass cover 20 is fixed to the display 50 as an outermost layer of the front surface of the electronic device 200. The glass cover plate 20 is made of a transparent material, so that the display screen 50 can be protected by the glass cover plate 20, and the display screen of the display screen 50 can be emitted through the glass cover plate 20.

The glass cover plate 20 and the side of the housing 10 are both part of the outer surface of the electronic device 200, and the edge position of the glass cover plate 20 and/or the side of the housing 10 is an arc surface in this embodiment, so that the edge position of the electronic device 200 can be smooth and beautiful. Alternatively, in other embodiments, only one of the edge position of the glass cover plate 20 and the side of the housing 10 may be a curved surface, the other one may be a flat surface, or both of them may be flat surfaces, which is not particularly limited.

Referring to fig. 6 and 7, in particular, in one embodiment, a first sound emitting portion 22 is formed between the end position of the glass cover plate 20 and the housing 10. The second sound emitting portion 14 is disposed inside the housing 10, and the second sound emitting portion 14 and the first sound emitting portion 22 are communicated with each other to form a sound emitting channel, so that the sound emitted from the receiver assembly 30 sequentially passes through the sound emitting channel and the second sound emitting portion 14 and the first sound emitting portion 22 to the outside of the glass cover plate 20. Specifically, the second sound emitting portion 14 is formed on a sidewall of the surrounding groove 12, and the second sound emitting portion 14 penetrates through the thickness of the whole housing 10.

In this embodiment, the first sound emitting portion 22 is a through groove, and the through groove is a gap naturally formed between the end surface of the glass cover plate 20 and the housing 10. In other embodiments, a portion of the end of the glass cover 20 and/or the housing 10 may be removed to form the first sound emitting portion 22. The first sound emitting portion 22 formed after removing the end portion of the glass cover 20 and/or a portion of the housing 10 may be an elongated groove, or a row of fine holes, as shown in fig. 8, which is not particularly limited. The second sound emitting portion 14 may also be a long through groove or a row of through holes, which is not particularly limited.

Optionally, in an embodiment, the width of the second sound emitting portion 14 is greater than the width of the first sound emitting portion 22. In different embodiments, the width of the first sound emitting portion 22 is greater than or equal to 0.3mm and less than or equal to 1 mm. Since the width of the first sound emitting portion 22 is very small, in order to make the sound emitted from the receiver assembly 30 better transmitted, the width of the second sound emitting portion 22 is made larger than that of the first sound emitting portion 22, and in different embodiments, the width of the second sound emitting portion 14 is greater than or equal to 1mm and less than or equal to 2 mm. In addition, the height of the second sound emitting portion 14, that is, the depth in the thickness direction of the housing 10 is much greater than the height of the first sound emitting portion 22. Since the height and width of the second sound-emitting portion 14 are larger than the width and thickness of the first sound-emitting portion 22, the sound emitted from the receiver assembly 30 can be transmitted to the second sound-emitting portion 14 quickly so as to be transmitted out of the first sound-emitting portion 22 quickly.

Specifically, due to space limitation, the axial lines of the first sound emitting portion 22 and the second sound emitting portion 14 are not on the same straight line, and in this embodiment, the axial lines of the first sound emitting portion 22 and the second sound emitting portion 14 are parallel to each other, and the sound emitting channel is in a zigzag shape. For example, in one embodiment, the first sound emitting portion and the second sound emitting portion are communicated to form an L-shape. In other embodiments, the first sound emitting portion 22 and the second sound emitting portion 14 may be disposed coaxially, which is not limited in particular. In the embodiment that the first sound emitting part 22 and the second sound emitting part 14 are arranged coaxially, the sound is transmitted in a straight line from the sound emitting channel at a higher speed.

Further, optionally, an expansion portion 142 is formed on an inner wall surrounding the second sound emitting portion 14, and the expansion portion 142 is located at a position where the top end of the second sound emitting portion 14 is connected to the first sound emitting portion 22. Further, the width of the connection position between the second sound emitting portion 14 and the first sound emitting portion 22 is increased. With this configuration, the sound transmitted to the second sound emitting portion 14 can reach the first sound emitting portion 22 quickly. Specifically, in one embodiment, the extension portion 142 is elongated, and the inner wall of the extension portion 142 on the side of the glass cover plate 20 is flush with the end surface of the glass cover plate 20. With this structure, sound can be transmitted to the first sound emitting portion 22 more quickly, and at the same time, the position where the first sound emitting portion 22 is disposed has a larger adhesive area between the housing 10 and the glass cover plate 20. In other embodiments, the inner wall of the expansion portion 142 on the side of the glass cover plate 20 may not be flush with the end surface of the glass cover plate 20, and this is not particularly limited.

In the embodiment in which the extension portion 142 is provided in the second sound emitting portion 14, the width of the extension portion 142 is larger than the width of the other portions of the second sound emitting portion 14, so that the sound transmitted from the receiver unit 30 enters the second sound emitting portion 14, then turns around the extension portion 142, and then rapidly enters the first sound emitting portion 22 and is transmitted out of the electronic device 200.

In order to achieve the waterproof function, in an embodiment, a waterproof glue 60 is disposed between the housing 10 and the glass cover plate 20 at the position of the first sound emitting portion 22, as shown in fig. 5. Since the first sound emitting portion 22 is provided at this position, an inlet is formed, and therefore, external moisture may enter from this position. The waterproof glue 60 is disposed between the housing 10 and the glass cover 20 at the position where the first sound emitting portion 22 is disposed, so that moisture can be prevented from entering the area where the display screen 50 is disposed from the inlet, and the display screen 50 is prevented from being in a wet environment.

Optionally, in an embodiment, the waterproof glue 60 is located between the glass cover plate 20 and the housing 10 to form a closed circumference, so that the position where the glass cover plate 20 is connected to the housing 10 forms a good sealing structure, and the display screen 50 is in a dry environment.

Alternatively, in an embodiment, the waterproof glue 60 extends outward away from the center direction of the glass cover plate 20 to form a protrusion 62, and the protrusion 62 covers the second sound emitting portion 14. In order to prevent the protruding portion 62 from blocking the sound outlet channel, a through portion 622 is formed on the protruding portion 62, and the through portion 622 is respectively communicated with the first sound outlet portion 22 and the second sound outlet portion 14, so that the sound emitted from the receiver assembly 30 can be smoothly transmitted out of the electronic device 200. By adopting the structure, the waterproof glue 60 surrounding the glass cover plate 20 for one circle can be ensured to have a larger area, and the width of one whole circle is coated consistently in the process of coating the waterproof glue 60. Then, the penetrating portion 622 is formed only at the position where the first sound emitting portion 22 is formed, thereby ensuring good waterproof performance all around the glass cover plate assembly 20.

The receiver assembly 30 is used as a part of the electronic device 200 for generating sound, and the receiver assembly 30 is connected to a side of the casing 10 opposite to the glass cover plate 20.

Referring to fig. 6 and 7, in particular, the receiver assembly 30 includes a mounting housing 32 and a receiver 34. The mounting case 32 is provided with an accommodating groove 322 and a sound-emitting groove 324 which are communicated with each other, the receiver 34 is fixed in the accommodating groove 322, and the sound-emitting groove 324 is communicated with the second sound-emitting portion 14. With such a configuration, the sound emitted from the receiver 34 is transmitted to the outside of the electronic apparatus 200 through the sound output groove 324, the second sound output unit 14, and the first sound output unit 22 in this order.

With reference to fig. 6 and fig. 7, in a further embodiment, the receiver assembly 30 further includes a limiting member 36, a first engaging portion 326 is disposed on a side of the mounting housing 32 away from the receiver 34, the limiting member 36 is connected to the first engaging portion 326, the limiting member 36 surrounds the sound groove 324, a communicating portion 362 is disposed on the limiting member 36, and the communicating portion 362 is respectively communicated with the sound groove 324 and the second sound outlet portion 14. It is understood that the communication portion 362 may be a small notch, or an elongated slot or through hole, and the width of the communication portion 362 is equivalent to the width of the second sound emitting portion 14, or slightly larger than the width of the second sound emitting portion 14. Since the receiver assembly 30 is disposed on a side of the housing 10 away from the glass cover 20, and the receiver 34 that emits sound is not directly opposite to the second sound-emitting portion 14 of the housing 10, but needs to pass through the sound-emitting slot 324 and then transmit to the second sound-emitting portion 14, and then transmit to the first sound-emitting portion 22 from the second sound-emitting portion 14, the path is long, for example, the path c in fig. 8 is a route that the receiver 34 emits sound and then transmits out of the glass cover 20 in the embodiment of the present application. In the embodiment without the limiting member 36, the sound outlet groove 324 is an open outlet, and only a part of the sound emitted from the receiver 34 enters the second sound outlet portion 14 through the sound outlet groove 324, and another part of the sound is diffused into the electronic device 200, so that the volume of the sound transmitted to the electronic device 200 becomes smaller.

In the embodiment of providing the limiting member 36 surrounding the sound outlet groove 324 in the receiver assembly 30, since the communication portion 362 is only a small outlet, it can be ensured that most of the sound emitted from the receiver 34 is transmitted to the second sound outlet portion 14, so as to ensure that the sound transmitted to the outside of the glass cover plate 20 is appropriate.

Specifically, in the present embodiment, the limiting member 36 is a metal member, such as a stainless steel material. Because the metal piece can be made to be very thin, the metal piece does not occupy too many positions, and the characteristic that the current electronic device is made to be light and thin is met. In other embodiments, the position-limiting member 36 may also be made of plastic or the like. Further, optionally, in an embodiment, the limiting member 36 is disposed in an injection molding manner with the mounting shell 32. In other embodiments, the position-limiting member 36 and the mounting shell 32 may be glued together, which is not limited in this respect.

In one embodiment, the communication portion 362 is disposed opposite to the second sound emitting portion 14, and in other embodiments, the communication portion 362 may be disposed slightly away from the second sound emitting portion 362, as long as most of the sound coming out of the sound emitting groove 324 can enter the second sound emitting portion 14, which is not particularly limited.

The back shell 40 is a shell on the back of the electronic device 200, the back shell 40 is connected to the housing 10, and the receiver assembly 30 is located between the housing 10 and the back shell 40. The receiver assembly 30 is enclosed by the back case 40 so that the receiver assembly 30 is not visible from the outer surface of the electronic device 200.

In one embodiment, the side of the glass cover 20 close to the receiver assembly 30 is provided with a second engaging portion 16, and the outer periphery of the back shell 40 is engaged with the second engaging portion 16 and fixedly connected to the housing 10. The second engaging portion 16 and the back shell 40 can be bonded or engaged, and are not limited in particular.

The electronic device 200 provided by the present application includes the glass cover plate assembly 100 and the display screen 50 described in the above embodiments. Specifically, the housing 10 is provided with a groove 12, the display screen 50 is disposed in the groove 12, and the glass cover plate 20 covers the display screen 50 and the housing 10. In this application, in one embodiment, the first sound emitting portion 22 and the second sound emitting portion 14 are disposed at a position corresponding to the upper end of the glass cover 20, that is, at the top edge of the electronic device 200, and in other embodiments. The first sound emitting portion 22 and the second sound emitting portion 14 may also be disposed at the edge of the other side of the electronic device 200, which is not limited in particular.

This application adopts above structure, sets up first sound portion 22 between the tip of glass apron 20 and casing 10, sets up second sound portion 14 in the inside of casing 10, and second sound portion 14 communicates with first sound portion 22 each other, constitutes the sound channel for the sound that the receiver subassembly 30 installed in casing 10 and deviating from one side of glass apron 20 sends out outside electron device 200 through the sound channel transmission. With the above structure, only the first sound emitting portion 22 occupies a part of the exterior of the electronic device 200, and the width of the first sound emitting portion 22 is in the range of 0.3mm-1mm, and is very small, so the first sound emitting portion occupies a very small position and is located at an edge position of the electronic device 200. In the present application, a row of sound emitting holes need not be formed in the position of the glass cover plate 20 relative to the receiver 34, so that the electronic device 200 has a larger screen occupation ratio.

The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
