[0047] In this embodiment, the body includes an outer shell 100, which has an inner cavity 200. A hollow area 201 is formed on the top of the outer shell 100, and the hollow area 201 is filled with a bracket block 202. A bracket groove 102 is formed in the bracket block 202; the bracket block 202 is embedded in the inner cavity 200 through the hollow area 201, and the bracket block 202 is connected to the outer shell 100 as a whole.
[0048] The integration of the bracket block 202 and the housing 100 enhances the stability between the mobile phone bracket and the speaker. At the same time, the hollow area 201 provides a spatial basis for the connection between the bracket block 202 and the inner cavity 200, making the connection between the bracket block 202 and the housing 100 tighter and improving the overall durability and reliability.
[0049] In this embodiment, a fixing ring 106 extends outward from the outer periphery of the top of the bracket block 202. The fixing ring 106 abuts against the outer shell 100 from top to bottom and is fixedly connected to the outer shell 100. In this way, the connection strength between the bracket block 202 and the outer shell 100 is enhanced. The fixing ring 106 provides an additional support point to ensure the stability and reliability of the bracket block 202 during use.
[0050] In this embodiment, a button 101 is provided on the housing 100 , a panel 105 extends outward from the fixing ring 106 , and a mounting hole 107 extending from top to bottom is provided in the panel 105 . The panel 105 abuts against the housing 100 from top to bottom, and the button 101 is passed through the mounting hole 107 .

[0053] In this way, the front wall 204 is opened and tilted, so that the mobile phone screen is opened to the maximum extent at the same time, with the largest screen area facing the user, making the viewing angle more comfortable; when the lower part of the mobile phone is embedded and fixed in the bracket groove 102, the back of the mobile phone abuts on the elastic strip 205, so that it can adapt to the back curves of different mobile phones and provide better abutment support and protection. Secondly, the elastic strip 205 abuts against the back of the mobile phone, which can play a shock-absorbing role for the mobile phone, and when the tilt angle of the mobile phone is adjusted, the back of the mobile phone will move relative to the elastic strip 205 to avoid damage to the back of the mobile phone.
[0054] In this embodiment, the adjusting shaft 300 is provided with a plurality of shock absorbing discs 301 made of elastic material, the shock absorbing discs 301 are arranged around the circumference of the adjusting shaft 300, and the plurality of shock absorbing discs 301 are arranged at intervals along the axial direction of the adjusting shaft 300; the outer circumference of the shock absorbing disc 301 is covered with a positioning ring 303, and the positioning ring 303 is arranged around the circumference of the shock absorbing disc 301;
[0055] The positioning groove 302 is formed on the positioning ring 303. The bottom of the positioning groove 302 passes through the positioning ring 303 and is connected to the outer periphery of the shock absorbing plate 301. The positioning groove 302 has a bottom support wall 304 facing the bottom of the mobile phone. When the lower part of the mobile phone is embedded in the bracket groove 102, the bottom of the mobile phone is embedded in the positioning groove 302 and abuts against the outer periphery of the shock absorbing plate 301 and the bottom support wall 304.
[0056] In this way, since the shock-absorbing plate 301 has elastic properties, the mobile phone can effectively absorb the impact force or vibration force when it is subjected to external impact or vibration, thereby alleviating the impact on the mobile phone; furthermore, the positioning ring 303 and the positioning groove 302 ensure that the mobile phone is firmly positioned on the adjustment axis 300, and can remain stable even when the angle of the mobile phone is adjusted, and the bottom support wall 304 provides additional support for the bottom of the mobile phone, making the mobile phone more securely fixed in the bracket groove 102, while providing a flexible angle adjustment function to meet the needs of different users.
[0057] In this embodiment, the positioning groove 302 has a partition wall 305 facing the back of the mobile phone and having an elastic spacing with the back of the mobile phone, and an elastic sheet 306 is protruded on the partition wall 305, and the two ends of the elastic sheet 306 are respectively fixedly connected to the partition wall 305, and the middle part of the elastic sheet 306 is elastically arched away from the partition part to form an arched part 307; when the bottom of the mobile phone is embedded in the positioning groove 302, the arched part 307 elastically abuts against the back of the mobile phone;
[0058] When the mobile phone is in the positioning groove 302, both ends of the elastic sheet 306 are fixedly connected to the partition wall 305, ensuring that the elastic sheet 306 can maintain its shape and position when the mobile phone is placed or taken out, thereby ensuring the stability of the mobile phone in the positioning groove 302; secondly, the arched portion 307 can provide a soft contact surface for the back of the mobile phone, reducing scratches or damage that may be caused by hard contact, especially when the back of the mobile phone has a fragile material or coating;
[0059] It not only improves the versatility and practicality of the mobile phone holder, but also enhances the protection of the mobile phone, while providing a better user experience.
[0060] In this embodiment, a sound guide tube 400 is provided in the inner cavity 200, and a straight sound guide channel 500 is provided inside the sound guide tube 400. The sound guide channel 500 passes through the inner end of the sound guide tube 400 to form an inner end opening 401. The inner end opening 401 is located in the inner cavity 200. The sound guide channel 500 passes through the outer end of the sound guide tube 400 to form an outer end opening 402. The outer end opening 402 is exposed on the side of the housing 100.
[0061] A plurality of bulging vibration membranes 502 made of elastic material are convexly disposed on the inner side wall 501 of the sound guide channel 500. The outer periphery of the vibration membrane 502 is fixedly connected to the inner side wall 501 of the sound guide channel 500. The vibration membrane 502 bulges away from the inner side wall 501 of the sound guide channel 500 and encloses the inner side wall 501 of the sound guide channel 500 to form a membrane cavity.
[0062] The outer surface of the vibration membrane 502 is formed with a plurality of protruding positions 503 protruding outward and a plurality of recessed positions 504 recessed inward, and the plurality of protruding positions 503 and the plurality of recessed positions 504 are arranged alternately at intervals; the middle portion of the vibration membrane 502 has a circular middle section 505;
[0063] The middle section 505 includes an inner membrane 506 arranged toward the membrane cavity and an outer membrane 507 arranged away from the membrane cavity. The outer periphery of the inner membrane 506 is butted together with the outer periphery of the outer membrane 507. The inner membrane 506 and the outer membrane 507 are arranged at intervals to form an interval cavity 508. A plurality of outer holes 509 are provided in the outer membrane 507, and the interval cavity 508 is connected to the outside through the plurality of outer holes 509.
[0064] By staggeredly arranging the plurality of raised portions 503 and recessed portions 504 on the outer surface of the vibration film 502, the vibration film 502 can produce more varied sound wave reflection and refraction effects when the speaker is working, thereby increasing the scattering of the sound waves, and improving the stereo effect and richness of the sound.
[0065] The double-layer membrane structure of the middle section 505 enables the relative movement of the inner and outer membranes 507 to enhance the response to sound waves when the diaphragm 502 vibrates, thereby improving the dynamic range and frequency response of the sound.
[0066] In addition, the spacing cavity 508 formed by the interval arrangement between the inner membrane 506 and the outer membrane 507 provides additional vibration space for the vibration membrane 502, which helps to reduce the nonlinear distortion of the vibration membrane 502 at high volume and maintain the clarity and purity of the sound. At the same time, the multiple outer holes 509 on the outer membrane 507 connect the spacing cavity 508 to the outside, optimize the frequency response curve of the speaker, and enable the speaker to maintain good sound performance at different frequencies. At the same time, it enhances the dynamic range and stereo effect of the sound, reduces distortion, and thus meets the user's demand for high-quality audio.
