Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-7, a physical sound amplifying device is used for a mobile phone 1, a sound unit 10 is arranged on the mobile phone 1, the sound unit 10 is a mobile phone speaker, and the physical sound amplifying device comprises a box body 2 and a clamping piece 3; the top of the box body 2 is provided with an embedded groove 20, one side of the embedded groove 20 is also provided with a first clamping groove 200, and the clamping piece 3 is clamped in the first clamping groove 200 and is matched with the embedded groove 20 to clamp the mobile phone 1; a sound inlet 21 is further arranged at the bottom of the embedded groove 20, the sound inlet 21 is attached to the sound generating unit 10, a sound outlet 22 is further arranged at one side of the box body 2, a sound amplifying cavity channel is further arranged in the box body 2, one end of the sound amplifying cavity channel is connected with the sound inlet 21, and the other end of the sound amplifying cavity channel is connected with the sound outlet 22; the bottom of the embedded groove 20 is also provided with a wire through hole 23 which is connected with and penetrates through one side wall of the box body 2.

Specifically, the mobile phone 1 is inserted into the insertion groove 20, and the sound played by the sound generating unit 10 on the mobile phone 1 enters from the sound inlet 21 arranged at the bottom of the insertion groove 20, is amplified by the sound amplification cavity channel in the shape of a horn, and is then emitted from the sound outlet 22. In general, one end of the sound box facing the human face is provided, so the sound outlet 22 is provided in a direction facing the human face, i.e. the front of the box body 2, or the sound outlet 22 can be provided on the left and right sides of the box body 2; the wire through hole 23 is used for penetrating a charging wire of the mobile phone 1 and is connected with the mobile phone 1, so that when the mobile phone 1 is low in electric quantity, a user does not need to worry about the phenomenon that the loudspeaker box is temporarily stopped due to the reduction of the electric quantity. Because the mobile phone 1 has various brands and different thicknesses, the insertion groove 20 with fixed size can not be perfectly connected with most mobile phones, so that the physical sound amplifying device with the insertion groove 20 can only be used for a few models or thicknesses of mobile phones, if a user purchases physical sound amplifying devices with different sizes, or the used mobile phones are replaced, the physical sound amplifying devices can not be used, and the use range of the physical sound amplifying devices is limited. The embodiment of the utility model provides an in, the accessible is changed different thickness dimension's fastener 3, comes to use with the cooperation of embedded groove 20 for the cell-phone of chucking embedding embedded groove 20, enlarges the cell-phone thickness scope that can embed, improves the suitability.

The clamping piece 3 is provided with a clamping part a and an adjusting part b, the clamping part a is clamped with the first clamping groove 200, and the adjusting part b extends into the embedded groove 20 and is matched with the embedded groove 20 to clamp the mobile phone 1. Specifically, the thickness range of the insertable mobile phone is expanded by arranging the card member 3 having the adjusting portions b of different thicknesses.

Further, the utility model discloses an embodiment, fastener 3 includes first fastener 31 and second fastener 32, is equipped with joint portion a and the adjustment portion b of different thickness of the same size on first fastener 31 and the second fastener 32, and box 2 bottom still is equipped with second draw-in groove 24, and joint portion a on first fastener 31 and the second fastener 32 all can be in the joint in first draw-in groove 200 or second draw-in groove 24. Be equipped with the fastener of two not unidimensional, can improve the cell-phone thickness scope that embedded groove 20 can be inserted to second draw-in groove 24 that box 2 bottom was equipped with can be when using one of them fastener joint cell-phone 1, and another idle fastener can insert in second draw-in groove 24, prevents to lose.

Further, in another embodiment of the present invention, the adjusting portion b is an elastic structure, and applies pressure to the mobile phone 1 through the elastic structure, so that the mobile phone 1 is clamped in the embedded groove 20.

Further, the wire through holes 23 are symmetrically arranged at both sides of the sound inlet 21. The position of the sound generating unit 10 on each mobile phone 1 is also divided into left and right parts according to different models of the mobile phones. In the embodiment of the present invention, both sides of the sound inlet 21 are provided with the wire through holes 23, if the sound generating unit 10 of the mobile phone 1 is close to the left side of the mobile phone 1, the mobile phone 1 can be embedded to the right when being embedded into the embedding groove 20; if the sound generating unit 10 of cell-phone 1 is close to the right side of cell-phone 1, then can imbed on a left side when cell-phone 1 imbeds embedded groove 20, the cell-phone 1 of having guaranteed each model all can use the utility model discloses carry out the physics public address.

Furthermore, a sealing ring is arranged outside the sound inlet 21. Due to the arrangement of the sealing ring, more sound emitted by the sound generating unit 10 can enter the sound amplification cavity channel, so that the excessive sound loss is prevented, and the sound amplification quality is reduced.

Furthermore, the mobile phone 1 is in an inclined state in the embedded groove 20 and is inclined towards the direction far away from the front surface of the box body 2, so that the front surface of the mobile phone 1 can be prevented from falling to the ground, and the mobile phone 1 is prevented from breaking; in one embodiment of the present invention, the sound outlet 22 is disposed on the front surface of the box body 2, the wedge 201 is disposed on both sides of the sound outlet 21 on the bottom of the embedded groove 20, the wedge 201 is inclined, and the end close to the sound outlet 22 is higher than the end far away from the sound outlet 22. It can be ensured that the mobile phone 1 is tilted backwards after the mobile phone 1 is inserted into the insertion groove 20. The arrangement of the wedge 201 can reduce the contact area between the bottom of the mobile phone 1 and the bottom of the embedded groove 20, increase the pressure of the mobile phone 1 on the wedge 201, further increase the pressure of the bottom of the mobile phone 1 on a sealing ring, and improve the sealing effect of the sealing ring, wherein the sealing ring is made of flexible materials such as rubber, silica gel and the like;

in another embodiment of the present invention, the sound outlet 22 is disposed on the front surface of the box body 2, the bottom of the embedded groove 20 is inclined, and the end close to the sound outlet 22 is higher than the end far away from the sound outlet 22, so that the mobile phone 1 can be tilted backwards.

Furthermore, the end of the sound amplifying cavity connected with the sound inlet 21 is arranged in a funnel shape, and the sectional area of the end is smaller than that of the sound inlet 21, so that a pressure cavity structure is formed. The sound generating unit 10 vibrates air while generating sound, and then moves and squeezes the air, so that the squeezed air passes through a channel with a smaller cross section, and the air flow rate is increased, thereby increasing the sound radiation impedance of the sound and reducing the distortion of the sound generating unit 10.

Further, the side of the embedded groove 20 away from the front surface of the box body 2 is inclined, and the inclined direction is inclined towards the direction away from the front surface of the box body 2. The inclined arrangement of one side of the embedded groove 20 far away from the front face of the box body 2 can reduce the pressure facing the back face of the mobile phone, and the mobile phone is protected. And at the same time, the mobile phone can be kept at the best backward tilting angle.
