Problems solved by technology
Because this kind of sound box structure forms the front and rear sound chambers through the cooperation between the plastic shells, because the plastic parts are not elastic, the airtightness of the cooperation between the parts is poor, so the airtightness of the front and rear sound chambers is affected. not ideal
When the speaker produces sound, the front and rear sound chambers are prone to sound leakage or broken sound, which makes the sound quality poor.
In addition, when the design of the existing speaker structure is changed, the chamber structure of the shell is generally modified to suit the assembly of the speaker components. This kind of speaker structure is easy to cause waste of the shell

Embodiment Construction
[0010] see figure 1 In the preferred embodiment of the present invention, a sound box structure 100 for an electronic device (such as a mobile phone, etc.) includes a casing 10 , a front rubber piece 20 , a speaker 30 , a rear rubber piece 40 and a circuit board 50 .
[0011] see figure 2 One end of the casing 10 is provided with a receiving cavity 12, which is formed on the inner surface of the casing 10 and has a square frame structure. The receiving cavity 12 is surrounded by a first bottom wall 14 and a first peripheral wall 16 . The first bottom wall 14 defines a sound outlet hole 142 , and a flange 144 is formed on the hole wall of the sound outlet hole 142 , and the flange 144 is used for engaging with the front rubber piece 20 . The first peripheral wall 16 is formed by connecting side walls with irregular shapes to each other, and surrounds the sound outlet hole 142 . The top of the first peripheral wall 16 has a matching surface 162 with irregular shape, and the ...

The invention provides a sound box structure of an electronic device, comprising a shell, a front rubber part, a loudspeaker, a back rubber part and a circuit board, wherein, the shell is provided with a containing cavity; the front rubber part and the back rubber part clamp the loudspeaker to contain the loudspeaker in the containing cavity of the shell, and the circuit board seals and covers the containing cavity; the front rubber part and one surface of the loudspeaker form a front sound chamber, and is matched with the shell; the back rubber part, one surface of the loudspeaker and the circuit board form a back sound chamber; and the back rubber part pushes against the circuit board. The sound box structure of the invention has good gas tightness and is convenient to revise the sound box structure during design.
Description
technical field [0001] The present invention relates to a sound box structure of an electronic device. Background technique [0002] Among electronic devices, electronic devices with a sound box structure are relatively common to meet the requirements of consumers for the function of playing external sound. This kind of sound box structure includes a loudspeaker, the loudspeaker is installed in a chamber on the shell, and the circuit board is against the opening of the chamber, and the sound-dissipating surface of the speaker, the shell and the side wall of the chamber form a front sound chamber , the back of the speaker, the circuit board and the side wall of the chamber form a rear sound chamber. The airtightness of the front sound chamber and the rear sound chamber constitutes an important factor for the sound quality of the loudspeaker. Since this kind of speaker structure forms the front and rear sound chambers through the cooperation between the plastic shells, since...
