Specific implementation and principle:

As shown in FIG. 1 , the loudspeaker phone case for use in a public environment includes a phone case 1, a camera opening 1-4, a fingerprint unlocking port 1-3, a charging port 1-2, a speaker opening 1-1, a speaker opening 1-1, and a speaker opening 1-1. A loudspeaker plate 2 is arranged directly below the opening 1-1, and the loudspeaker plate 2 is located on the back of the mobile phone, and is used to bounce most of the sound from the opening 1-2 of the loudspeaker to the user's face, so as to prevent the sound from going to the left and right. and spread behind.

As shown in Figures 2 and 3, the loudspeaker board 2 is located below the large support board 3, and the large support board 3 is connected to the back of the mobile phone case 1 through the rotating shaft 4, so that the large support board 3 can be leveled around the rotating shaft 4. Rotating, the large support plate 3 includes the upper part 3-1, the middle part 3-2, and the right part 3-4 for placing the backing plate 10 and the latch movement slot 7, the large support plate 3 can drive the rotation of the sound rebound board 2 to make the sound rebound board 2. Receiving the bottom side of the mobile phone, the u-shaped pin slot 5 is fixedly connected to the back of the mobile phone case 1, which acts as a limiter when the large pallet rotates. 2Vertical to the bottom side of the phone.

As shown in FIG. 5 , the loudspeaker panel 2 includes a protruding portion 2-1 located at the bottom side of the speaker opening 1-1 for rebounding sound, the tail portion 2-3 is cylindrical, and both ends of the tail portion 2-3 protrude to the right. Put the corner code fixed on the middle 3-2 of the large pallet 3, so that the loudspeaker can rotate up and down with the tail 2-3 as the center, and a limit plate 9 is set in front of the tail 2-3 to prevent the loudspeaker 2 from rotating. The degree is too large, so that it can be turned over to the back of the phone to damage the extension 2-1.

As shown in FIG. 6 , the plug 6 includes a front part 6-1 that can be inserted into the u-shaped plug groove 5. When the loudspeaker board 2 is retracted to the back of the mobile phone case, the plug 6 can be fixed. The middle part 2-2 of the board 2 produces pressure, and presses the loudspeaker board 2 against the rear part 6-3 fixed on the large pallet 3, the rough part 6-4 where the fingers can slide, the pin 6 can be between the backing board 10 and the pin The moving grooves 7 move in parallel, and the thickness of the backing plate 10 is the same as that of the middle part 2-2 of the loudspeaker plate 2. The sliding of the rough part 6-4 by the fingers can drive the latch 6 to retreat. A locking mechanism 11 is provided above the bolt moving guide rail 18 and the bolt moving groove 7 .

As shown in Figures 7 and 8, there is a small sleeve rod 15 on the pin moving groove 7, and the small sleeve rod 15 can cover the spring 16 and the sleeve ring 12-3 on the clamping plate 12. The clamping plate 12 includes 12- 1. The groove 12-1, the protrusion 12-2 that can be pressed into the card slot 6-2, the finger sliding plate 14 that can be slid by the fingers and drives the card position plate 12 to rotate, the finger sliding plate 14 is connected by the connecting rod 13, the spring One corner of the 16 is connected to the spring support protrusion 17, and the other foot is connected to the groove 12-1, which can provide downward pressure for the locking plate 12. When a person slides the finger sliding plate 14, the finger sliding plate 14 is small. The sleeve rod 15 is rotated as the center, so that the protrusion 12-2 is separated from the locking groove 6-1, so that the latch can move forward.

As shown in FIG. 9 , there are side ears 2-4 on both sides of the protruding part 2-1 of the loudspeaker plate 2. When the loudspeaker plate 2 of the mobile phone case 1 is stretched out, the sound propagating in the left and right directions can be directed to It bounces in the direction perpendicular to the screen of the mobile phone. The protruding part 2-1 in the middle of the side ears 2-4 is arc-shaped, which can bounce the sound propagating to the back of the mobile phone and away from the opening 1-1 of the speaker to the direction perpendicular to the screen of the mobile phone. .

As shown in FIG. 12 , the U-shaped pin slot includes a base 5-2 fixedly connected to the back of the mobile phone case 1, which can be inserted by the pin 6 and press the u-shaped plate 5-1 of the loudspeaker board 2 through the rear part 6-3.

When people use the mobile phone in public and need to release the sound of the mobile phone, the amplifying board 2 is all stored on the back of the mobile phone case 1, the latch 6 is retracted to the right side of the sound-emitting board 2, and the card slot 6-2 is connected to the The protrusions 12-2 are matched together, and the latch 6 is in a locked state. You can slide the finger slide plate 14 first, and the card position plate 12 starts to rotate around the small sleeve rod 15. After turning to the top of the latch 6, the protrusion 12-2 Separate from the card slot 6-2, and then slide the rough part 6-4 with your fingers to push the latch 6 forward. At this time, the loudspeaker board 2 is located between the latch 6 and the large support plate 3 until the front part 6-1 moves to the latch. In the fixing slot 5, the loudspeaker board 2 is locked. At this time, the loudspeaker board 2 cannot rotate up and down through the tail portion 2-3, and the sound propagating in all directions is transmitted to the vertical direction due to the extension 2-1 of the loudspeaker board 2 The direction of the mobile phone screen rebounds, so that it does not affect the normal work and study of other people, but also has a sound amplification effect for the user. When the mobile phone case is not needed for sound amplification, the rough part 6-4 of the plug 6 Backwards, when the front part 6-1 of the latch 6 is in contact with the latch moving groove 7, the loudspeaker board 2 can rotate up and down without the pressure of the latch 6, and the protrusion 12-2 of the locking plate 12 is acted by the spring 12-1 Press into the card slot 6-2, and the latch 6 returns to the locked state. Next, continue to slide the rough part 6-4. Because the latch moving slot 7 is fixedly connected with the large support plate 3, it drives the large support plate 3 to wrap around as a whole. Rotate counterclockwise along the rotating shaft 4 until the loudspeaker panel 2 is completely received on the back of the mobile phone case and stops.

Based on the above, the utility model is simple in structure and flexible in use, and is not only convenient to switch, but also small in size by providing a loudspeaker plate and a large support plate that can slide in and out. When it is used, it slides out to bounce the sound to the user's face, allowing the user to hear a louder sound.
