DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field based on the present application belong to the scope of protection of the present application.

[0049] In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first" and "second" are used to distinguish the same items or similar items with substantially the same functions and effects. For example, the first instruction and the second instruction are to distinguish different user instructions, and their order is not limited. Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not necessarily limit them to be different.

[0050] It should be noted that, in this application, words such as "exemplarily" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplarily" or "for example" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.

[0051] In addition, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, where a, b, c can be single or multiple.

[0052] With the development of electronic technology, electronic devices such as mobile phones and tablets are gradually becoming thinner and lighter. The thinning of the overall thickness of the device has compressed the thickness of the audio device, and at the same time, the cross-sectional area of ​​the audio device's sound channel has also been gradually compressed. When the length of the sound channel is constant, the thickness and width of the sound channel become the biggest factors limiting the audio performance. Taking mobile phones as an example, in the related technology, mobile phones such as Figure 1 As shown in the figure, the front cavity sound outlet channel is between the screen and the speaker assembly. When the length of the front cavity sound outlet channel is constant, the thickness and width of the front cavity sound outlet channel directly affect the flow rate of the airflow. The higher the flow rate of the airflow, the greater the noise caused by the airflow. Therefore, under the premise of making electronic devices thinner and lighter, how to make full use of the thickness of the whole machine and improve the audio performance has become an urgent problem to be solved.

[0053] In view of this, an embodiment of the present application provides an electronic device, including:

[0054] Display screen, front cavity sound outlet channel, speaker assembly;

[0055] The display screen has a local groove structure, the position of the local groove structure corresponds to the position of the front cavity sound outlet channel, and the local groove structure is used to increase the cross-sectional area of ​​the front cavity sound outlet channel;

[0056] The front cavity sound outlet channel is used to export the sound emitted by the speaker assembly.

[0057] The electronic device in the embodiment of the present application may be a mobile phone or a tablet, etc. The front cavity sound outlet channel is used to export the sound emitted by the speaker assembly to the outside of the electronic device. When the length and width of the front cavity sound outlet channel have been determined, the thickness of the front cavity sound outlet channel (i.e., the thickness direction of the electronic device) is the most critical factor affecting the airflow velocity. The greater the thickness, the smaller the airflow velocity, and the smaller the airflow noise caused by the airflow velocity. In the embodiment of the present application, a local groove structure is provided at a position corresponding to the front cavity sound outlet channel on the display screen. Through the local groove structure, the thickness of the front cavity sound outlet channel is increased, that is, the cross-sectional area of ​​the front cavity sound outlet channel is increased, so that the velocity of the airflow can be slowed down to reduce the airflow noise and improve the audio performance of the electronic device.

[0058] The display screen is usually composed of a protective layer area, a functional layer area and a non-functional layer area. The protective layer area may include a glass encapsulation layer; the functional layer area includes various functional layers for supporting touch and display, such as an anode layer, a cathode layer, an electroluminescent layer, etc.; the non-functional layer area may include a buffer layer and a heat dissipation layer, etc. Under normal circumstances, the thickness of the functional layer area is difficult to change; and when the protective layer area becomes thinner, the strength will also decrease accordingly, thereby affecting the life of the display screen; therefore, in one possible way, see Figure 2 The display screen includes a protective layer area 211, a functional layer area 212, and a non-functional layer area 213; the local groove structure 2131 is provided in the non-functional layer area 213 at a position corresponding to the front cavity sound outlet channel. The local groove structure 2131 is provided in the non-functional layer area 213, which has little effect on the functional layer area 212 and the protective layer area 211, and has almost no effect on the life of the display screen.

[0059] The non-functional layer area 213 may include a buffer layer and a heat dissipation layer, etc. In some examples, the buffer layer and the heat dissipation layer may also be a layer, that is, a heat dissipation buffer layer. It is understandable that in the embodiment of the present application, a local groove structure 2131 is opened at a position corresponding to the front cavity sound outlet channel in the non-functional layer area 213, rather than removing the non-functional layer area 213. In a possible implementation, taking the above-mentioned non-functional layer area 213 including: a buffer layer and a heat dissipation layer as an example, the above-mentioned local groove structure 2131 is obtained by cutting the above-mentioned buffer layer and / or the above-mentioned heat dissipation layer. The local groove structure 2131 can be obtained by cutting the buffer layer and / or the heat dissipation layer, and the cutting thickness can be specifically determined according to the thickness of the designed local groove structure 2131. It is understandable that the thickness of the local groove structure 2131 should not exceed the thickness of the non-functional layer area 213, otherwise it may affect the functional layer area 212. In a possible implementation, the thickness of the above-mentioned local groove structure 2131 is not less than 0.2mm. The thickness of the local groove structure 2131 is set to be greater than 0.2 mm, which can effectively increase the cross-sectional area of ​​the front cavity sound outlet channel, thereby reducing airflow noise and improving the audio performance of the electronic device. It can be understood that the thickness of not less than 0.2 mm here is only an example, and the thickness of the local groove structure 2131 can also be less than 0.2 mm, all within the protection scope of this application.

[0060] In a possible implementation, the speaker assembly includes a speaker core and a speaker cavity wall, and the speaker core is disposed in the speaker cavity wall.

[0061] The speaker assembly may include a speaker core and a speaker cavity wall, and in some embodiments, the speaker assembly may also include a pickup core, etc. The speaker core may include a speaker and a speaker circuit for achieving sound generation. The speaker cavity wall is used to protect the speaker core and facilitate the installation of the speaker and the speaker circuit. The speaker core is arranged in the speaker cavity wall. In one example, in order to reduce the impact on the vibration of the speaker, the speaker can be vacated and fixed in the speaker cavity wall through at least three supporting points to meet the vibration requirements of the speaker in the speaker core.

[0108] The front cavity sound outlet channel 22 is a cavity structure between the speaker core 31 and the front cavity wall 281; the rear cavity 26 is a cavity structure between the speaker core 31 and the rear cavity wall 282;

[0109] A sound outlet slot 27 is provided between the middle frame 24 and the display screen 21 ; the sound outlet slot 27 is in communication with the front cavity sound outlet channel 22 .

[0110] Figure 8 2 shows a partial structural diagram of another electronic device; one end of the speaker core 31 is connected to the front cavity wall 281, and the other end of the speaker core 31 is connected to the rear cavity wall 282; the speaker cavity wall 28 wraps the speaker core 31, and there is a front cavity sound outlet channel 22 between the speaker core 31 and the front cavity wall 281, and there is a rear cavity 26 between the speaker core 31 and the rear cavity wall 282. There is a gap between the display screen 21 and the rear cavity wall 282, and there is a gap between the front cavity wall 281 and the inner screen 29. The speaker core 31 will vibrate when making a sound, so it may drive the vibration of the speaker cavity wall 28, and the above two gaps can be used as a buffer space for vibration, thereby protecting the display screen 21 and the inner screen 29. In an example, the above rear cavity wall 282 has a second local convex groove structure 2821, and the above second local convex groove structure 2821 cooperates with the above local groove structure 2131 to increase the thickness of the above front cavity sound outlet channel 22, that is, to increase the cross-sectional area of ​​the front cavity sound outlet channel 22. In the embodiment of the present application, by adding the speaker cavity wall 28 structure, the stability of the speaker assembly 23 can be increased and the speaker assembly 23 can be protected.
