Embodiment 1

[0034] The damping element in Embodiment 1 includes a first damping ring 16, a second damping ring 15, and a third damping ring 14, and the cross-sectional shape of the first damping ring 16, the second damping ring 15, and the third damping ring 14 is a notch facing the shaft. A concave font in the direction of the heart. The battery board 3 is clamped on the notch of the first damping ring 16 , the circuit board 4 is clamped on the notch of the second damping ring 15 , and the horn holder 5 is clamped on the notch of the third damping ring 16 .

[0035] In order to fix the position 14 of the first damping ring 16, the second damping ring 15 and the third damping ring, three damping ring fixing grooves are arranged on the inner wall of the bottom case 2, which are respectively the first damping ring fixing groove and the second damping ring fixing groove . The third damping ring fixing groove, wherein the first damping ring is formed by the steps inside the bottom case 2 and ...

Embodiment 2

[0038]The damping part in the second embodiment includes an integrated damping ring 17, the outer peripheral wall of the integrated damping part 17 is attached to the inner wall of the bottom case 2, the bottom is on the bottom of the bottom case 2, and the top is covered by the mesh cover 1 Pressing during the fastening process; the integrated damping ring 17 has three annular fixing grooves, and the battery board 3 , circuit board 4 , and speaker fixing frame 5 are respectively stuck in the corresponding fixing grooves.

[0039] The inner diameters of the groove bottoms of the three fixing grooves should match the radial dimensions of the corresponding battery board 3, circuit board 4 and horn holder 5, so that the battery board 3, circuit board 4 and horn holder 5 can be fixed more firmly. Radial position; the width of the three fixing grooves should match the axial dimensions of the corresponding battery board, circuit board and speaker holder, so as to fix the axial positi...

Embodiment 3

[0041] The damping member in the third embodiment includes three damping columns, which are respectively the first column 18, the second column 19, and the third column 20. In specific implementation, three or more damping columns can be set according to requirements to achieve better performance. fixed effect.

[0042] On the battery board 3, the circuit board 4 and the loudspeaker fixing frame 5, there are upright holes equal in number to the damping uprights at the same vertical position. The damping column passes through the column hole of the battery board 3, the circuit board 4 and the speaker fixing frame 5, and the two ends are respectively fastened to the bottom of the bottom case and the side of the mesh cover facing the inner cavity.

[0043] On the outer circumference of each damping column, there are three annular grooves for holding the battery board 4, the circuit board 5, and the speaker fixing frame 6, and the battery board 3, the circuit board 4, and the spea...

Abstract

The invention discloses a high-shock-resistance portable loudspeaker provided with a USB interface. The portable loudspeaker comprises a housing, a battery board, a circuit board, a horn unit and a damping piece. The battery board, the circuit board and the horn unit of the portable loudspeaker are fixed in an inner cavity of the housing by the damping piece, so that when the portable loudspeaker encounters a violent shock, a partial impact force can be absorbed by deformation of the damping piece; the battery board, the circuit board and the loudspeaker unit can be effectively protected against an excessive impact force; the service life of the portable loudspeaker is prolonged; an application scope of the portable loudspeaker is increased; the portable loudspeaker has good practicability.

Description

technical field [0001] The invention relates to the field of portable audio, in particular to a high shock-resistant portable audio with a USB interface. Background technique [0002] With the improvement of living standards, portable speakers with small size, powerful functions and low power consumption are becoming more and more popular, and gradually become a consumer fashion. Many domestic and foreign electronics companies have launched various types of portable audio to meet the growing consumer demand. [0003] Portable audio is mainly used in outdoor use occasions, and needs to be played while moving frequently. The internal components of the existing portable audio mainly adopt rigid fastening methods, and the internal parts of the audio are fixed on the shell through rigid connection methods such as screw fastening; In the fastening method, due to insufficient elastic deformation at the moment of shock, a large instantaneous impact force will be generated, which i...
