[0028] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0037] In the related art, different models of terminal devices such as mobile phones have different sizes of internal components, which results in the middle frame structure not being universal. Different models require customized matching middle frame structures for internal components to achieve the assembly effect between the components and the middle frame structure.

[0038] Among them, internal devices such as sound output components have different sizes. In order to properly install the sound output components, the accommodation space on the middle frame structure for installing the sound output components usually needs to be designed into a single size according to the size of the sound output components, so that the sound output components and the middle frame structure can be matched for installation. However, a middle frame structure designed with a single size for the sound output component will result in the middle frame structure not being universally used in terminal devices of different models, which increases the production cost of the terminal device, prolongs the development cycle of the terminal device, and is not conducive to the rapid production of the terminal device and timely market launch.

[0039] And due to the requirements of the sound output area of ​​the sound output component, the small-sized sound output component cannot be forcibly installed in a large space. If the small-sized sound output component directly replaces the large-sized sound output component and is installed in the middle frame structure, different-sized sound output components require different sound output areas. If they are installed in mismatched spaces, the audio effect of the sound output component will be affected, reducing the user experience.

[0040] The present disclosure proposes a middle frame structure, which is installed on a terminal device, and a sound output component is installed on the middle frame structure to realize the audio function of the terminal device. The sound output component is, for example, a speaker unit and an earpiece unit. Among them, the middle frame structure includes a middle frame body and a mounting portion, the middle frame body is formed with a accommodating space, the accommodating space is provided with a first opening, the mounting portion is detachably mounted at the first opening, and sound output components of different sizes are mounted on the middle frame structure through the mounting portion, which further realizes the universal effect of the middle frame structure, shortens the production cycle of the terminal device, and reduces costs. When the sound output component is a speaker unit, the speaker unit can be directly installed at the first opening to realize the audio function of the terminal device. When the sound output component is a earpiece unit, the earpiece unit is installed at the first opening through the mounting portion. Different sound output components can share the middle frame structure, which reduces the manufacturing difficulty and saves production costs.

[0041] In an exemplary embodiment, Figure 1-Figure 6 As shown, a middle frame structure 1 is installed in a terminal device to load components inside the terminal device. An audio component 2 in the terminal device is installed in the middle frame structure 1 to implement audio functions of the terminal device, such as communication functions, audio and video playback, etc.

[0042] In this embodiment, still refer to Figure 1-Figure 6 As shown, the middle frame structure 1 includes a middle frame body 11 and a mounting portion 12. The middle frame body 11 is formed with a receiving space 111. The receiving space 111 is provided with a first opening 112. The mounting portion 12 is detachably mounted at the first opening 112. By arranging the mounting portion 12 in the receiving space 111, sound output components 2 of different sizes can be mounted on the middle frame structure 1. There is no need to design different middle frame structures 1 for different sizes of sound output components 2, thereby reducing the production cost of the terminal device and shortening the development cycle of the terminal device.

[0043] In one example, referring to Figure 5 , Figure 6 As shown, when the sound output component 2 is a speaker unit 21, the speaker unit 21 can be directly installed at the first opening 112. The speaker unit 21 is, for example, a 10mmx12mm speaker, and the speaker unit 21 can be directly bonded to the inner wall of the accommodating space 111.

[0044] For example, the middle frame structure 1 includes a second adhesive portion 13 , which may be a double-sided adhesive, etc. When the speaker unit 21 is installed, the circumferential outer wall of the speaker unit 21 is bonded to the inner wall of the accommodating space 111 through the second adhesive portion 13 .

[0045] Of course, the speaker unit can also be installed in the accommodation space by other means besides bonding. For example, the speaker unit can also be snapped into the accommodation space for easy disassembly to avoid damage to the middle frame structure during later maintenance. The speaker unit is set in the middle frame structure to achieve the stereo speaker mode effect of the sound output component and improve the audio effect of the terminal device.

[0046] In another example, referring to Figure 1-Figure 4 As shown, when the sound output component 2 is an earpiece unit 22, the earpiece unit 22 is installed at the first opening 112 through the mounting portion 12. The earpiece unit 22 is, for example, a speaker of 8mmx9mm, and a single-sized accommodating space 111 is set on the middle frame structure 1. The earpiece unit 22 cooperates with the mounting portion 12 to be installed in the middle frame structure 1. Sound output components 2 of different sizes can share the middle frame structure 1, realizing the versatility of the middle frame structure 1 and saving development costs. The earpiece unit 22 can be designed in a terminal device that does not require high audio effects, reducing the production cost of the terminal device.

[0047] In an exemplary embodiment, Figure 1-Figure 6 As shown, the mounting portion 12 includes a mounting body 121 , and the mounting body 121 is detachably mounted in the accommodating space 111 through the first opening 112 .

[0048] In one example, referring to Figure 2 As shown, the outer wall of the installation body 121 can be bonded and connected to the inner wall of the accommodating space 111 to improve the reliability of the connection between the installation body 121 and the accommodating space 111.

[0049] In another example, referring to Figure 3 , Figure 4 As shown, the mounting portion 12 further includes a second elastic stopper 123 disposed on the outer side wall of the mounting body 121. The second elastic stopper 123 may be made of, for example, thermoplastic resin. When the mounting body 121 is in the mounted state, the inner side wall of the accommodating space 111 is in contact with the second elastic stopper 123.

[0050] When the mounting body 121 is mounted in the accommodating space 111, the second elastic limiting portion 123 disposed on the mounting body 121 abuts against the inner wall of the accommodating space 111. The second elastic limiting portion 123 provides a thrust to move the mounting body 121 in a direction away from the second elastic limiting portion 123, and the circumferential outer wall of the mounting body 121 abuts against the inner wall of the mounting area 1211 to limit the movement of the mounting body 121, thereby ensuring that the mounting body 121 can be stably mounted in the accommodating space 111.

[0051] The mounting body 121 is further formed with a mounting area 1211, and the earpiece unit 22 is mounted in the mounting area 1211. The mounting area 1211 may be, for example, a mounting space recessed in the mounting body 121, and the earpiece unit 22 is directly mounted in the mounting space.

[0052] In this embodiment, still refer to Figure 2-Figure 4 As shown, the mounting body 121 is provided with a second opening 1212, which is communicated with the mounting area 1211, and the receiver unit 22 is mounted in the mounting area 1211 through the second opening 1212. The size of the second opening 1212 is smaller than the size of the first opening 112, so that the mounting body 121 can be smoothly installed in the accommodating space 111, and the receiver unit 22 can be assembled.

[0053] In one example, referring to Figure 2 As shown, the middle frame structure 1 further includes a first adhesive portion 14, which may be, for example, a double-sided adhesive. When the earpiece unit 22 is installed, the earpiece unit 22 is bonded to the inner wall forming the installation area 1211 through the first adhesive portion 14, thereby ensuring the reliability of the connection between the earpiece unit 22 and the middle frame structure 1.

[0054] In another example, referring to Figure 3 , Figure 4 As shown, the mounting portion 12 further includes a first elastic stopper 122 disposed on the inner side wall of the mounting area 1211. The first elastic stopper 122 may be made of, for example, thermoplastic resin. When the receiver unit 22 is installed, the circumferential outer side wall of the receiver unit 22 abuts against the first elastic stopper 122.

[0055] The first elastic limiting portion 122 and the second elastic limiting portion 123 may be independent of each other (see Figure 3 As shown), the first elastic limiting portion 122 and the second elastic limiting portion 123 may also be formed in one piece (refer to Figure 4 As shown in the figure, the specific implementation method shall be subject to the actual design. The above example is only used to explain this embodiment and does not constitute a limitation to this application. As long as the first elastic limiting portion 122 can limit the movement of the earpiece unit 22, and the second elastic limiting portion 123 can limit the movement of the mounting body 121, it is sufficient.

[0056] When the earpiece unit 22 is installed in the installation area 1211, the first elastic limiting portion 122 abuts against the circumferential outer wall of the earpiece unit 22. The first elastic limiting portion 122 provides a thrust to squeeze the earpiece unit 22 in a direction away from the first elastic limiting portion 122, and the circumferential outer wall of the earpiece unit 22 abuts against the inner wall of the installation area 1211 to limit the movement of the earpiece unit 22, ensuring that the earpiece unit 22 can be stably installed in the installation area 1211.

[0057] Of course, it is understandable that a plurality of first elastic limiting portions can be provided, and the plurality of first elastic limiting portions are provided along the circumferential outer wall of the earpiece unit, so that the circumferential outer wall of the earpiece unit is abutted and connected with all the first elastic limiting portions, thereby further limiting the movement of the earpiece unit, improving the installation effect of the earpiece unit, preventing the earpiece unit from leaving the installation area, ensuring the normal use of the earpiece unit, and improving the user's experience.

[0058] In an exemplary embodiment, Figure 1-Figure 4 As shown, the middle frame structure 1 also includes a first sealing layer 15, which is, for example, foam. The first sealing layer 15 is arranged on the inner bottom wall forming the installation area 1211, and the first sealing layer 15 is in contact with the sound output component 2 to seal the gap between the sound output component 2 and the inner bottom wall of the installation body 121, thereby improving the sealing performance of the installation area 1211 and ensuring the sound conduction performance of the sound output component 2. To avoid the phenomenon of unclear audio when the sound output component 2 is working, the first sealing layer 15 can ensure the normal operation of the sound output component 2 and improve the user experience.

[0059] In this embodiment, refer to Figure 1-Figure 6 As shown, the middle frame structure 1 further includes a second sealing layer 16, which is, for example, foam. The second sealing layer 16 is disposed on the inner bottom wall of the accommodating space 111 to improve the sealing performance of the accommodating space 111 and ensure the normal operation of the sound output component 2.

[0060] Reference Figure 5 , Figure 6 As shown, when the sound output component 2 is a speaker unit 21, the speaker unit 21 is in contact with and connected to the second sealing layer 16 to seal the gap between the speaker unit 21 and the inner bottom wall of the accommodating space 111, thereby ensuring the sealing performance of the accommodating space 111 and improving the conduction performance of the speaker unit 21 after outputting audio.

[0061] Reference 2- Figure 4As shown, when the sound output component 2 is an earpiece unit 22, the mounting body 121 is in contact with the second sealing layer 16 to seal the gap between the mounting body 121 and the inner bottom wall of the accommodating space 111, thereby ensuring the sealing performance of the accommodating space 111 and improving the conduction performance of the earpiece unit 22 after outputting audio.

[0062] Of course, it is understood that the above-mentioned positions of the first sealing layer and the second sealing layer are only used to explain this embodiment and do not constitute a limitation to this application. The first sealing layer can also be set along the circumferential outer wall of the earpiece unit to close the gap between the earpiece unit and the installation area. The second sealing layer can also be set along the circumferential outer wall of the mounting body or the speaker unit to improve the sealing performance of the accommodating space and prevent the front cavity and the rear cavity of the terminal device from intercommunication and interfering with each other.

[0063] The present disclosure also provides a terminal device, which may be, for example, a mobile phone, a tablet computer, etc. The terminal device includes a sound output component and the above-mentioned middle frame structure. The sound output component is installed in the middle frame structure to realize the audio function of the terminal device. Among them, the sound output component may be, for example, a receiver unit to realize the audio function of the terminal device, so that the user can communicate through the terminal device. The sound output component may also be, for example, a speaker unit, which may have both the function of communication and the effect of a stereo speaker mode, further improving the audio output effect of the terminal device and meeting the user's usage needs.
