Description

Technical Field

[0001] This application relates to the field of terminal equipment technology, and in particular to a mobile terminal. Background Technology

[0002] With the advancement of technology and the ever-increasing consumer demand, consumers are increasingly looking for terminal devices. Portable and easy-to-use mobile terminals, such as smartphones and tablets, are becoming increasingly popular.

[0003] As smartphones become increasingly thinner while fulfilling various functions, the space for speakers is shrinking. Smartphones typically only have one or two speakers, resulting in poor full-range stereo sound. However, adding too many speakers affects the screen-to-body ratio, impacts aesthetics, and hinders achieving a truly slim design. Furthermore, current mainstream smartphones lack a prominent music theme, and their sound production process and presentation are relatively simplistic, leaving room for improvement in user experience and market competitiveness. Summary of the Invention

[0004] The main purpose of this application is to propose a mobile terminal that aims to solve the technical problems of existing mobile terminals having a relatively simple sound-emitting process and form, making it difficult to achieve a thin and compact design.

[0005] To achieve the above objectives, embodiments of this application propose a mobile terminal, comprising:

[0006] Back cover;

[0007] A first speaker is mounted on the rear housing, and a sound cavity for the first speaker is formed inside the rear housing; the first speaker is a bass unit.

[0008] A lighting effect component is housed within the acoustic cavity of the first speaker, and the lighting effect component is configured to match a corresponding lighting effect according to the operating state of the mobile terminal.

[0009] In this application's mobile terminal, the first speaker, serving as the bass unit, is mounted on the rear shell, and a sound cavity for the first speaker is formed within the rear shell, enabling the first speaker to emit sound normally. Compared to the prior art where the bass speaker is placed at the top or bottom of the mobile terminal, this application places the bass unit on the rear shell, forming a sound cavity for the bass unit within the rear shell. This does not occupy additional space, achieving a thinner design, and does not affect the screen-to-body ratio, thus maintaining the aesthetic appeal.

[0010] This application's mobile terminal also includes a lighting effect component, which is housed within the sound cavity of the first speaker. This component does not occupy additional space, facilitating a slim design without affecting the screen-to-body ratio or aesthetic appeal. The lighting effect component can match corresponding lighting effects based on the mobile terminal's operating state, thus creating a pleasant atmosphere. Understandably, the mobile terminal's operating states include power-on, screen-off, incoming call, call, and audio playback. For example, when the mobile terminal is in screen-off mode, if it receives a text message or voice call, the lighting effect component can match the corresponding lighting effect, serving as a prominent reminder. Similarly, when the mobile terminal is playing music, the lighting effect component matches the music playback, such as changing the light color, intensity, and duration based on the timbre, audio level, and loudness of the music. This highlights the music theme while simultaneously creating a pleasant atmosphere, enriching the mobile terminal's audio playback process and enhancing the user experience and market competitiveness.

[0027] With the advancement of technology and the ever-increasing consumer demand, consumers are increasingly looking for terminal devices. Portable and easy-to-use mobile terminals, such as smartphones and tablets, are becoming increasingly popular.

[0028] As smartphones become increasingly thinner while fulfilling various functions, the space for speakers is shrinking. Smartphones typically only have one or two speakers, resulting in poor full-range stereo sound. However, adding too many speakers affects the screen-to-body ratio, impacts aesthetics, and hinders achieving a truly slim design. Furthermore, current mainstream smartphones lack a prominent music theme, and their sound production process and presentation are relatively simplistic, leaving room for improvement in user experience and market competitiveness.

[0029] This application provides a mobile terminal that solves the above-mentioned problems.

[0030] like Figures 1 to 5 As shown, in one embodiment of this application, the mobile terminal 100 includes a rear shell 10, a first speaker 40, and a lighting effect component 60. The first speaker 40 is mounted on the rear shell 10 and a sound cavity 41 of the first speaker 40 is formed inside the rear shell 10. The first speaker 40 is a bass unit. The lighting effect component 60 is housed in the sound cavity 41 of the first speaker 40 and is configured to match the corresponding lighting effect according to the working state of the mobile terminal 100.

[0031] In this application, the mobile terminal 100 may be a mobile phone or a tablet, etc. This application will use a mobile phone as an example for illustration.

[0032] In the mobile terminal 100 of this application, a first speaker 40, serving as a bass unit, is mounted on the rear cover 10, and a sound cavity 41 for the first speaker 40 is formed within the rear cover 10, enabling the first speaker 40 to emit sound normally. Compared to the prior art where the bass speaker is placed at the top or bottom of the mobile terminal 100, this application places the bass unit on the rear cover 10 and forms a sound cavity 41 for the bass unit within the rear cover 10, thus not occupying additional space, achieving a thinner design, and not affecting the screen-to-body ratio, thereby not affecting the aesthetic appearance.

[0033] The mobile terminal 100 of this application also includes a lighting effect component 60, which is housed within the sound cavity 41 of the first speaker 40. This does not occupy additional space, facilitating a thinner design without affecting the screen-to-body ratio or aesthetic appeal. The lighting effect component 60 can match corresponding lighting effects according to the working state of the mobile terminal 100, thus creating a pleasant atmosphere by simultaneously applying lighting effects to the mobile terminal 100's operating state. Understandably, the working states of the mobile terminal 100 include powered on, screen off, incoming call, call, or audio output, etc. Taking the mobile terminal 100 in a screen-off state as an example, when the mobile terminal 100 receives a text message or voice call, the lighting effect component 60 can match the corresponding lighting effect, serving as a prominent reminder. Taking the mobile terminal 100 in sound output mode as an example, when the mobile terminal 100 plays music, the lighting effect component 60 matches the corresponding lighting effect according to the music playback. For example, different light colors, light intensities, and lighting durations can be changed according to the different timbre, audio, and loudness of the music being played. Thus, while highlighting the music theme, the lighting effect creates a good atmosphere, enriches the sound output process and form of the mobile terminal 100, enhances the user experience, and improves the market competitiveness of the mobile terminal 100.

[0034] In one embodiment, the mobile terminal 100 further includes at least one second speaker 50, and the second speaker 50 is a mid-high frequency unit. The first speaker 40 and at least one second speaker 50 form a full-range stereo system, that is, the first speaker 40 and at least one second speaker 50 form a 2.1 channel system to realize the 2.1 channel function and improve the sound effect.

[0035] In one embodiment, the mobile terminal 100 may include two second speakers 50, one of which is a midrange unit and the other is a tweeter unit, or both of the second speakers 50 are midrange-high range units. The mobile terminal 100 can be configured with the second speakers 50 as needed, which is flexible and convenient.

[0036] Understandably, the mobile terminal 100 also includes a screen 20 and a mid-frame 30. The screen 20 is installed on the front of the mid-frame 30, and the back cover 10 is installed on the back of the mid-frame 30. The mobile terminal 100 may include two second speakers 50, which are respectively located at the top and bottom of the mobile terminal 100. Correspondingly, a second sound outlet 31 for the top second speaker 50 to emit sound is opened on the front of the mid-frame 30 at the top of the screen 20, and another second sound outlet 31 for the bottom second speaker 50 to emit sound is opened at the bottom of the mid-frame 30. The two second speakers 50 emit sound towards the top and bottom of the mobile terminal 100, respectively. The back cover 10 has a first sound outlet 15 for the first speaker 40 to emit sound, and the first speaker 40 emits sound towards the rear, so that the sound is distributed in space, achieving a stereo effect and improving the sound experience. The first speaker 40 and the second speaker 50 of this application can be large-size, high-power, and high-volume speakers. The second speaker 50 at the top serves as the left channel speaker, the second speaker 50 at the bottom serves as the right channel speaker, and the first speaker 40 serves as the mixing speaker to achieve a stereo sound effect and further enhance the sound experience.

[0037] In one embodiment, the middle frame 30 has two oppositely arranged side frames located between the bottom and top of the middle frame 30. The second speaker 50 at the top is located near one of the side frames, while the second speaker 50 at the bottom is located near the other side frame. The first speaker 40 is located near the top of the middle frame 30. The layout is reasonable, does not affect the screen ratio, and does not take up extra space, thus achieving a thin design.

[0038] In one embodiment, the rear cover 10 is also equipped with at least one camera 70. The at least one camera 70 is located near one of the side frames, and the first speaker 40 is located near the other side frame. The layout is reasonable and avoids interference between the camera 70 and the first speaker 40. The first speaker 40 and the second speaker 50 at the top are correspondingly arranged along the direction from the screen 20 to the rear cover 10, that is, correspondingly arranged from front to back. The layout is reasonable and the structure is compact.

[0039] The mobile terminal 100 of this application also includes a motherboard 80, which is installed inside the rear cover 10. The motherboard 80 includes a main processor chip 81, which is configured to drive a full-range stereo system to produce sound. By driving the full-range stereo system to produce sound through the main processor chip 81, the mobile terminal 100 can achieve high-quality audio output, optimize the audio experience, improve the system integration and flexibility, and enhance the user experience.

[0040] Specifically, the main processor chip 81 drives the first speaker 40 and at least one second speaker 50 to produce sound, thereby enhancing the audio experience. Furthermore, each first speaker 40 is equipped with a power amplifier 83, and each second speaker 50 is also equipped with a power amplifier 83. The main processor chip 81 drives the corresponding first speaker 40 and at least one second speaker 50 through the power amplifiers 83. The power amplifiers 83 amplify power, increase signal strength, and improve signal fidelity, further enhancing the audio experience.

[0041] In one embodiment, the motherboard 80 further includes a driver chip 82, which is configured to drive the lighting effect component 60 to match the corresponding lighting effect according to the sound output state of the full-range stereo system; wherein, the operating state of the mobile terminal 100 includes the sound output state of the full-range stereo system. By setting the driver chip 82, the mobile terminal 100 of this application enables the driver chip 82 to precisely control the brightness, color, and dynamic effects of the lighting effect component 60 according to the sound output state of the full-range stereo system, thereby matching the corresponding lighting effect with good matching performance.

[0042] like Figure 4 and Figure 5 As shown, in one embodiment, a sound cavity 41 is formed between the motherboard 80 and the rear shell 10. The lighting effect component 60 includes a light source 61 and a light guide 62. The light guide 62 is disposed on the path of the light beam emitted by the light source 61. The rear shell 10 is provided with a light-transmitting area 11. The light beam emitted by the light source 61 is diffused by the light guide 62 and then emitted from the light-transmitting area 11.

[0043] It should be noted that in the accompanying drawings of this application, Figure 5 The dashed arrows indicate the beam of light and its direction of emission. Figure 1 , Figures 6 to 9 The dashed arrows indicate the direction of the emitted light beam and the boundary of the emitted area. Additionally, the structures located in the non-transparent areas inside the mobile terminal 100 in the accompanying drawings are not visible; the visualization of the internal structures in the accompanying drawings is to illustrate the relationships between the various structures.

[0044] The motherboard 80 and the rear shell 10 form a sound cavity 41 for the first speaker 40, and can form a relatively large sound cavity 41 to meet the requirements of a large sound cavity 41. Furthermore, the sound cavity 41 of the first speaker 40 does not occupy additional space, which is conducive to achieving a thin design. A light-transmitting area 11 is provided on the rear shell 10 to facilitate the emission of light beams from the light-transmitting area 11, presenting a light-transmitting effect. When the lighting effect component 60 is working, the light source 61 emits a light beam, and the light guide 62 is placed on the path of the light beam emitted by the light source 61. The light beam emitted by the light source 61 is diffused by the light guide 62 and then emitted from the light-transmitting area 11 to achieve the lighting effect.

[0045] In one embodiment, a hollow area 12 is formed in the rear shell 10 corresponding to the position of the first speaker 40. A decorative plate 13 is provided in the hollow area 12. The decorative plate 13 has a first sound outlet 15. The first speaker 40 emits sound through the first sound outlet 15 to the rear shell 10. The first sound outlet 15 forms a light-transmitting area 11.

[0046] Decorative panel 13 is installed over the hollow area 12, serving a decorative purpose and enhancing the aesthetic appearance of the mobile terminal 100. The decorative panel 13 has a first sound outlet 15, facilitating normal sound output from the first speaker 40. Furthermore, the first sound outlet 15 forms a light-transmitting area 11, allowing light to pass through and be diffused by the light guide 62 before exiting through the first sound outlet 15. The first sound outlet 15 serves both sound output and light transmission functions, eliminating the need for an additional light-transmitting area 11 and simplifying the structure. Moreover, the first sound outlet 15 consists of multiple holes, allowing light to pass through and creating a variety of lighting effects.

[0047] It should be noted that the decorative panel 13 of the mobile terminal 100 of this application has multiple holes to serve as both a protective and dustproof feature while forming the first sound outlet 15. One of the holes can be a relatively large strip-shaped hole, allowing the sound outlet of the first speaker 40 to communicate with the strip-shaped hole and achieve sound output. The remaining holes can be configured as a microporous structure arranged at intervals around the strip-shaped hole to allow light transmission, thereby avoiding interference between light transmission and sound output.

[0048] To enhance the aesthetic appeal of the mobile terminal 100, a decorative ring 14 is provided around the perimeter of the decorative panel 13, and a dustproof and waterproof mesh 19 is attached between the decorative panels 13 to provide dust and water protection. Furthermore, the decorative panel 13 is made of metal, which is not only easy to manufacture but also has a textured feel. The decorative ring 14 is a two-color injection molded ring, which is easy to mold and presents a multi-color effect, further improving the aesthetic appeal.

[0049] like Figure 6 As shown, in one embodiment, there are multiple lighting effect components 60, which are spaced apart along the periphery of the hollow area 12; the driving chip 82 is configured to drive multiple light sources 61 to independently emit light beams according to the sound output state of the full-range stereo system to match the corresponding lighting effect.

[0050] By setting multiple lighting effect components 60, and with the driver chip 82 driving multiple light sources 61 to independently emit beams of light according to the sound output state of the full-range stereo system to match the corresponding lighting effects, the lighting effects become rich and varied, enhancing the lighting experience. Furthermore, the multiple lighting effect components 60 are spaced along the periphery of the hollow area 12, resulting in a reasonable layout. The beams emitted by the multiple light sources 61 can all be emitted from the first sound outlet 15 through their respective light guides 62, resulting in a simple and compact structure.

[0051] like Figure 4 and Figure 5 As shown, in other embodiments, the rear shell 10 has a first sound outlet 15, through which the first speaker 40 emits sound to the rear shell 10, facilitating normal sound output from the first speaker 40. The rear shell 10 is recessed towards the motherboard 80 to form a groove 16, with the opening 161 of the groove 16 facing away from the motherboard 80. A light-shielding film 17 and a light-transmitting thin plate 18 are sequentially covered at the opening 161 facing away from the motherboard 80. A light-transmitting area 11 is formed on the light-shielding film 17 located in the beam path, and the light-transmitting area 11 is disposed to avoid the first sound outlet 15.

[0052] Specifically, the rear shell 10 faces the main board 80, forming a recessed groove 16. The opening 161 of the groove 16 faces away from the main board 80, meaning the opening 161 of the groove 16 is positioned rearward. A light-shielding film 17 and a light-transmitting thin plate 18 are sequentially covered at the opening 161 from front to back. The light-shielding film 17 can be made of PET film, and the light-transmitting area 11 can be flexibly set according to actual needs. The light-transmitting area 11 is on the beam path. The beam emitted by the lamp source 61 is diffused by the light guide 62 and then emitted sequentially from the light-transmitting area 11 and the light-transmitting thin plate 18, achieving the lighting effect. By setting the light-shielding film 17, and by creating a variety of light-transmitting areas 11, a variety of lighting effects can be achieved. Moreover, the light-shielding film 17 and the light-transmitting thin plate 18 are positioned at the groove 16, without occupying additional space, which is beneficial for achieving a thin design. The light-transmitting area 11 is arranged to avoid the first sound outlet 15, with sound output and light transmission separated. This allows the light output of the light-transmitting area 11 to be unrestricted by the structure of the first sound outlet 15, and the light-transmitting area 11 can be flexibly configured in various ways according to requirements. In one embodiment, the light-transmitting thin plate 18 can be made of light-transmitting glass, which facilitates light transmission and has a textured feel.

[0053] like Figures 7 to 9 As shown, there is at least one lighting effect component 60, which is disposed on one side of the first speaker 40, and each lighting effect component 60 corresponds to a light-transmitting area 11. The rear shell 10 of the mobile terminal 100 of this application is also provided with at least one camera 70. The camera 70 and the lighting effect components 60 are respectively disposed on both sides of the first speaker 40, resulting in a reasonable and aesthetically pleasing layout. Each lighting effect component 60 corresponds to a light-transmitting area 11, and the driving chip 82 is configured to drive at least one light source 61 to independently emit a beam of light according to the sound output state of the full-range stereo system to match the corresponding lighting effect.

[0054] By setting at least one lighting effect component 60, and especially multiple lighting effect components 60, the driver chip 82 can drive multiple light sources 61 to independently emit beams according to the sound output state of the full-range stereo system to match the corresponding lighting effect, making the lighting effect rich and colorful and enhancing the lighting effect experience.

[0055] like Figure 7As shown, in another embodiment, when there are multiple lighting effect components 60, the multiple light-transmitting areas 11 are interconnected, making the multiple light-transmitting areas 11 more concentrated and simple to set up. For example, when there are two lighting effect components 60, the two light-transmitting areas 11 are interconnected to form a whole area, and the two light sources 61 illuminate the whole area from opposite directions. The whole area can present the same color, different colors, or mixed colors, etc., to enrich the lighting effect.

[0056] like Figure 8 As shown, in another embodiment, when there are multiple lighting effect components 60, the multiple light-transmitting areas 11 are spaced apart from each other, so that the multiple light-transmitting areas 11 are set separately to avoid mutual interference.

[0057] like Figure 9 As shown, in another embodiment, when there are multiple lighting effect components 60, the multiple light-transmitting areas 11 are arranged sequentially, resulting in a simple layout and high aesthetic appeal. For example, when there are three lighting effect components 60, the three light-transmitting areas 11 are arranged sequentially along the length of the mobile terminal 100. This allows the three light-transmitting areas 11 to display different colors, brightness, and durations at different times, creating more lighting effects, such as a marquee-like effect. It is understandable that the three light-transmitting areas 11 can display different colors sequentially over time, or simultaneously display different colors, etc.

[0058] In one embodiment, when the light-emitting ends of any two adjacent light sources 61 are facing away from each other, the two adjacent light sources 61 are separated by a light-shielding film. The light-shielding film can be made of PET black film, which is used to cover the light-emitting end face of the light source 61 to avoid interference between the light beams emitted by the two light sources 61 and to prevent light leakage, stray light, and local high brightness.

[0059] In one embodiment, the light source 61 is an RGB light, and the light guide 62 is a nano-molded dot light guide module. The light beam emitted by the light source 61 is diffused circumferentially by the light guide 62 and then projected from the light-transmitting area 11 to the outside of the rear shell 10. RGB lights offer a variety of colors and are easy to source. The light guide 62, being a nano-molded dot light guide module, achieves efficient light propagation and distribution through nanoscale dot patterns, offering advantages such as high luminous efficiency, thinness, high resolution, low energy consumption, and design flexibility.

[0060] In one embodiment, a flat shielding cover 84 is provided on the motherboard 80, located within the sound cavity 41. The lighting effect component 60 is located on the side of the shielding cover 84 facing away from the motherboard 80. The shielding cover 84 has an opening communicating with the sound cavity 41. The shielding cover 84 can reduce electromagnetic interference, improve signal integrity, optimize thermal management, and provide physical protection. Moreover, the flat shape of the shielding cover 84 reduces space occupation and facilitates a thin design. The opening in the shielding cover 84 communicating with the sound cavity 41 allows the space inside the shielding cover 84 to also serve as the sound cavity 41, expanding the volume of the sound cavity 41 and improving sound effects.

[0061] To reduce space occupation and achieve a slim and lightweight design for the mobile terminal 100, the dimensions of the light source 61 in this application's mobile terminal 100 are 3mm × 1mm × 0.4mm; the motherboard 80 is a flexible circuit board with a thickness of 0.12mm to 0.2mm; the thickness of the nano-molded dot light guide module is 0.3mm to 0.4mm; a portion of the shielding cover 84 has a height of 0.8mm and a thickness of 0.1mm to 0.2mm; a portion of the back cover 10 uses a 0.2mm thick hard sheet to improve texture and strength; specifically, the hard paddle can be a steel sheet 101. Through the above-mentioned design of various thin structures, the mobile terminal 100 utilizes the sound cavity 41 of the first speaker 40 to set up the lighting effect component 60, achieving ambient lighting effects while simultaneously enabling sound output from the back of the mobile terminal 100, without increasing the overall length, width, or thickness, thus achieving a slim and lightweight design and a high screen-to-body ratio for the mobile terminal 100.

[0062] In one embodiment, the light source 61 is a tri-color RGB light, which can change brightness and mix colors. Multiple light sources 61 emit beams independently, and can emit different colors, brightness, and on / off states, enriching the lighting effects. The light sources 61 can be placed on the same plane as the corresponding light guides 62, and the beams emitted by the light sources 61 are diffused by the light guides 62 and then emitted from the light-transmitting area 11.

[0063] In one embodiment, the first speaker 40 of the mobile terminal 100 is fixed between the rear shell 10 and the motherboard 80, with the rear shell 10 and the motherboard 80 forming a sound cavity 41 for the first speaker 40, and the periphery is sealed with foam 90. In another embodiment, if the entire device is designed as a waterproof machine, the internal volume space of the entire device can be used as the sound cavity 41 of the first speaker 40, without the motherboard 80 and the rear shell 10 forming it. That is, the rear shell 10 does not need to seal the motherboard 80, the motherboard 80 is less restrictive, and the layout area of ​​the motherboard 80 can be increased.

[0064] Taking a mobile terminal 100 equipped with two lighting effect components 60, two second speakers 50, and one first speaker 40 as an example, one lighting effect component 60 is located near the top of the mobile terminal 100, and the other lighting effect component 60 is located near the bottom of the mobile terminal 100. When the second speaker 50 at the top plays music, the top lighting effect component 60 illuminates; when the second speaker 50 at the bottom plays music, the bottom lighting effect component 60 illuminates; when the first speaker 40 emits sound, or when both second speakers 50 and the first speaker 40 play music simultaneously, both lighting effect components 60 illuminate simultaneously. The brightness of the light source 61 increases with the volume of the corresponding first speaker 40 or second speaker 50, creating a breathing effect.

[0065] Alternatively, when the second speaker 50 at the top plays music, both lighting components 60 emit blue light; when the second speaker 50 at the bottom plays music, both lighting components 60 emit green light; and when the first speaker 40 plays music, both lighting components 60 emit red light. The two light sources 61 in the two lighting components 60 can display red, green, and blue light respectively, and can mix colors, not only creating a breathing effect and a pleasant atmosphere, but also providing illumination for functions such as charging, caller ID, and SMS notifications.
