Detailed Description

The utility model is further elucidated below in conjunction with the accompanying drawings.

The directions referred to in the specification are all based on the directions of the mobile phone loudspeaker when the mobile phone loudspeaker works normally, the directions of the mobile phone loudspeaker during storage and transportation are not limited, and only the relative position relationship is represented, and the absolute position relationship is not represented.

As shown in fig. 1-4, a mobile phone loudspeaker comprises a support base 1, wherein a sound guide cavity 2 is arranged in the support base 1, one surface of the support base 1 is provided with a fixed groove 3, the fixed groove 3 is formed by sinking one end of the support base 1 into the sound guide cavity 2, the bottom of the fixed groove 3 is provided with a sound guide through hole 4, one end of the sound guide through hole 4 is connected with the bottom of the fixed groove 3, and the other end of the sound guide through hole 4 is connected with the sound guide cavity 2; the one end that the sound conduction through-hole 4 was kept away from to sound conduction chamber 2 is provided with public address set 5 and backup pad 6, public address set 5 includes public address chamber 7, public address chamber 7's length direction is the same with the length direction of sound conduction through-hole 4, backup pad 6 fretwork sets up, backup pad 6 covers public address chamber 7 towards the one end that supports base 1, be provided with sound pipe 10 in the public address chamber 7, sound pipe 10 keeps away from the one end and the sound conduction chamber 2 intercommunication of public address chamber 7. When the mobile phone fixing device is used, a mobile phone needs to be placed in the fixing groove 3, and the supporting base 1 plays a role of a fixing support. When the mobile phone plays videos or music, sound enters the sound guide cavity 2 through the sound guide through hole 4, and the sound is reflected and spread in the sound guide cavity 2 until reaching one end of the sound guide cavity 2 close to the sound guide pipe 10. Then sound reaches the sound amplifying cavity 7 along the sound guide pipe 10, then the sound is reflected and spread along the sound amplifying cavity 7, then reaches the outside through the hollowed-out area of the supporting plate 6, the transmission of the sound is completed, and the volume of the sound is increased by reducing the diffusion of the sound in the spreading process, so that the sound amplifying effect is realized.

In summary, the device has the following advantages: the support base 1 is combined with the fixed groove 3, so that the device has the function of a mobile phone bracket; secondly, the sound guide cavity 2, the sound guide pipe 10, the sound amplifying device 5 and the support plate 6 cooperate with each other, so that sound emitted by the mobile phone is converged and emitted after the sound is converged, loss in the sound transmission process is reduced, the sound volume of the sound is increased, and the sound amplifying function is realized; thirdly, the hollowed-out area of the support plate 6 also enables sound to be emitted from the loudspeaker 5 better.

In order to collect the sound emitted by the player, preferably, the sound guiding cavity 2 includes a sound collecting cavity 2a and a sound outlet cavity 2b, the sound collecting cavity 2a is communicated with the sound outlet cavity 2b, the sound collecting cavity 2a is arc-shaped, the inner outline size of the sound collecting cavity 2a is smaller than the inner outline size of the sound outlet cavity 2b, one end of the sound guiding through hole 4 is connected with the sound collecting cavity 2a, and the other end of the sound guiding pipe 10 is communicated with the sound outlet cavity 2 b. The inner contour of the sound collection chamber 2a is smaller, which reduces the propagation path of sound, thereby facilitating the collection of sound in the sound outlet chamber 2b having a larger inner contour.

In order to avoid supporting plate 6 hugs closely with support base 1 and leads to the unable outward propagation of sound from megaphone chamber 7, be provided with supporting shoe 8 between supporting plate 6 and the support base 1, the one end of supporting shoe 8 is connected with support base 1, and the other end of supporting shoe 8 is connected with supporting plate 6, supporting shoe 8 includes guide channel 9, guide channel 9's length direction is the same with the length direction of sound guide tube 10, sound guide tube 10 passes guide channel 9. The support block 8 not only realizes the support of the loudspeaker 5, but also leaves a gap between the support plate 6 and the support base 1, thereby reducing the obstruction to sound transmission.

In order to further reduce the obstruction of the sound transmission by the support blocks 8, it is preferred that the outer dimensions of the support blocks 8 are smaller than the outer dimensions of the support plates 6. This design reduces the coverage of the support block 8 to the hollowed-out area of the support plate 6, so that sound can be transmitted from the hollowed-out area to the periphery.

In order to increase the volume of sound emitted by the sound amplifying chamber 7, it is preferable that the sound amplifying chamber 7 is composed of a plurality of cross sections parallel to the support plate 6, and the areas of the plurality of cross sections are gradually reduced from one end of the sound amplifying chamber 7 near the support base 1 to one end of the sound amplifying chamber 7 far from the support base 1. This design makes the sound amplifying chamber 7 resemble a "horn head" so that sound is collected at the location of the support plate 6 along the length direction of the sound amplifying chamber 7, and the sound emitted by the sound amplifying device 5 is further louder.

In order to facilitate the fixing of the sound guide tube 10, it is preferable that the support plate 6 includes a guide hole 11, one end of the guide hole 11 is connected to the guide passage 9, the other end of the guide hole 11 is connected to the sound amplifying chamber 7, and the sound guide tube 10 passes through the guide hole 11.

For the convenience of the connection of the support block 8 and the support plate 6, the inner wall of the guide hole 11 is provided with internal threads, the outer wall of the support block 8 is provided with external threads, and the support block 8 is in threaded connection with the guide hole 11.

In order to facilitate the fixing of the loudspeaker 5, the support plate 6 is preferably adhesively or screwed to the loudspeaker 5.

In this scheme, because the space between the loudspeaker 5 and the support base 1 is narrower, the support block 6 is inconvenient in installation, and therefore, the support block 6 and the support base 1 are integrally formed. This design also makes the support base 1 easier to mass produce.

In order to reduce the space occupied by the device conveniently, preferably, the supporting block 8 and the fixing groove 3 are positioned at the same end of the supporting base 1.

In order to reduce the diffusion of sound, preferably, the inner diameter of the sound collecting cavity 2a near the end of the sound conducting through hole 4 is larger than the inner diameter of the sound collecting cavity 2a near the end of the sound outlet cavity 2 b. The design ensures that the sound entering the sound collecting cavity 2a is continuously reflected and collected in the process of propagating along the sound collecting cavity 2a, thereby reducing the loss of the sound in the process of propagating.

In order to make the device more ornamental, the sound amplifying device is preferably a hollow animal horn 5. Of course, the speaker 7 is not limited to the animal horn, and may be of other shapes, and may be of animal horn made of other materials.

The present utility model is not limited to the above-described specific embodiments, and various modifications may be made by those skilled in the art without inventive effort from the above-described concepts, and are within the scope of the present utility model.
