Problems solved by technology

[0003] Existing passive radiators usually adopt the method of artificially cold-bonding the counterweight and the diaphragm. Although this connection method is simple, the edge of the counterweight will have glue overflow or gaps, and the accuracy of artificial cold-gluing Low, difficult to guarantee quality

Embodiment Construction

[0030] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.

[0031] In the present invention, unless expressly stipulated and defined otherwise, the "above" or "below" of the first feature of the second feature may include the first and second features in direct contact, or may include the first and second features Not in direct contact but through other features between them. Moreover, the "above" of the first feature on the second feature includes the first feature directly above and obliquely above the second feature, or it simply means that the first feature is higher in level than the second feature. The "below" of the first feature under the second feature includes the first feature directly below and diagonally below the second feature, or it simply means that the level of the first feature is smaller than the second feature.

Abstract

The invention discloses a passive radiator and a manufacturing method thereof, the passive radiator is arranged on a mounting hole of a sound box shell and comprises a bracket, a vibrating diaphragm and a balancing weight, the bracket is fixed on the sound box shell, the vibrating diaphragm comprises a connecting part and an accommodating part with a hollow cavity, the balancing weight is arrangedin the hollow cavity, the connecting part is connected with the bracket, and the vibrating diaphragm seals the mounting hole. The balancing weight is wrapped in the vibrating diaphragm, so that the balancing weight is firmly fixed, and the product quality is improved.

Description

Technical field [0001] The invention relates to the technical field of audio equipment, in particular to a passive radiator and a manufacturing method thereof. Background technique [0002] Passive radiators are also called passive units. Their appearance is similar to that of active speaker units. They are all set on the mounting holes of the speaker shell. However, passive radiators only have a diaphragm, without a voice coil and driving magnet, and the movement of the diaphragm. Propelled by the airflow in the box. Passive radiators are usually used to adjust the bass, allowing designers to adjust the overall tone of the speaker. [0003] Existing passive radiators usually adopt the method of artificial cold bonding of the counterweight and the diaphragm. Although this connection method is simple, the edge of the counterweight will be glued or separated, and the accuracy of manual cold bonding Low, the quality is difficult to guarantee. Summary of the invention [0004] An obj...
