[0033] The handle main body 1 is connected with a connecting wire 2 at one end of the sound receiving part 13, the connecting wire 2 is arranged with an audio amplification circuit, a through slot is formed in the side of the holding part 11, the adjusting assembly 6 comprises a rotating wheel 61 and two guide rails 64, the rotating wheel 61 is rotatably installed on the side wall of the holding part 11 and rotatably arranged in the through slot in the side of the holding part 11, the two guide rails 64 are fixedly connected to the two opposite inner walls of the holding part 11, respectively, and a sliding plate 65 is slidably arranged between the two guide rails 64.

[0034] The arc-shaped sliding pointer 610 is fixedly connected to the side opposite to the sliding plate 65 and the rotating wheel 61, and the arc-shaped opening of the arc-shaped sliding pointer 610 is slidably attached to the surface of the adjusting resistor 69 downward.

[0035] The worm 62 is arranged beside the worm gear 63 which is in meshing transmission with the worm 62, and the worm gear 63 is rotatably arranged in the holding part 11. The rack 66 which is in meshing transmission with the worm gear 63 is fixed to the side of the sliding plate 65.

[0036] The elastic supporting assembly comprises two columns 67 which are fixed in the holding part 11, two sliding blocks 68 which are respectively arranged on the two columns 67, and springs 611 which are arranged on the two columns 67 and below the sliding blocks 68.

[0039] During use, the user cannot shield the voice of the other party when using the telephone handle to talk, which affects the expression of the user and the expression accuracy of the user. In the present scheme, the worm 62 is rotated by rotating the worm wheel 61, and the worm gear 63 is rotated by the worm 62. Since the rack 66 is in meshing transmission with the worm gear 63, the sliding plate 65 is driven to slide between the two guide rails 64 by the rack 66 when the worm gear 63 rotates, and the arc-shaped sliding pointer 610 on the side of the sliding plate 65 is driven to slide on the surface of the adjusting resistor 69. The resistance value between the connecting wire 2 and the sound generating assembly 3 is adjusted when the arc-shaped sliding pointer 610 slides on the adjusting resistor 69, and the sound size of the sound generating assembly 3 is adjusted, so that the information expressed by the other party can be accurately received.

[0040] When the other party is too noisy to affect the user's expression, the spring 611 will always push the sliding block 68 upward in the initial state to make the sliding block 68 adhere to the baffle 612, and the end of the button 614 extends out of the holding part 11, and the limiting column 617 is kept in the horizontal segment of the right-angle limiting groove 616. By rotating the button 614, the button 614 drives the limiting column 617 on the side thereof to translate in the horizontal segment of the right-angle limiting groove 616 and move to the corner column of the horizontal segment and the vertical segment of the right-angle limiting groove 616. Then, the button 614 is pressed into the holding part 11, and the button 614 drives the limiting column 617 to move into the vertical segment of the right-angle limiting groove 616. When the button 614 is retracted into the holding part 11, the U-shaped frame 613 is driven to move downward, and the two sliding blocks 68 are driven to slide on the two vertical columns 67, and the two sliding blocks 68 are driven to press the spring 611 to retract, thereby driving the adjusting resistor 69 between the two sliding blocks 68 to move downward. At this time, the adjusting resistor 69 is separated from the arc-shaped sliding pointer 610, thereby breaking the connection of the arc-shaped sliding pointer 610 and the adjusting resistor 69, thereby breaking the signal transmission to the sound production assembly 3, so as to achieve the effect of shielding the sound production of the sound production assembly 3. At this time, the user can express the information that he wants to express.

[0041] By arranging the porous resonance sound-absorbing plate 34 in the horn opening 31, when talking, the porous resonance sound-absorbing plate 34 can absorb the sound waves emitted by the sound production module 32 and enter the resonance cavity 35 through the small holes thereon, and cause air vibration. When the frequency of the sound wave is the same as the natural frequency of the air, resonance phenomenon occurs. The friction between the air and the porous resonance sound-absorbing plate 34 and the friction between the air molecules in the resonance process can convert and offset the sound energy, so as to achieve the effect of sound absorption. By adjusting the vibration frequency of the sound wave passing through the holes of the porous resonance sound-absorbing plate 34 to filter the high-frequency vibration in the sound wave, and cooperating with the effect of blocking external noise by the sound insulation cotton 4, the sound quality of the call is improved.

[0042] Cooperating with the effect of improving the call volume, the effect of avoiding that the other party cannot accurately express due to too small voice is achieved, and the voice of the other party can be shielded to avoid affecting the expression accuracy of the user.

[0043] The above shows and describes the basic principle, main features and advantages of the utility model. It should be understood by those skilled in the art that the utility model is not limited by the above examples. The above examples and descriptions in the specification are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model can have various changes and improvements. These changes and improvements all fall within the scope of the utility model.
