Description

Technical Field

[0001] This utility model relates to the field of speaker technology, and in particular to a speaker. Background Technology

[0002] A speaker is an audio device that converts electrical signals into sound signals.

[0003] An existing speaker includes a housing, a speaker, and a passive radiator. The housing has mounting cavities, and the speaker and passive radiator are mounted in these cavities at intervals along the front-rear direction of the housing. The speaker protrudes from the front side of the housing, and the passive radiator separates the front-rear mounting cavities. The rear side of the housing has an exhaust port facing the passive radiator. When the speaker operates, the vibration of the speaker diaphragm generates a shock wave on the air between the passive radiator and the speaker. This shock wave acts on the passive radiator, causing it to resonate. The vibration of the passive radiator impacts the air between it and the housing, causing the air to escape through the exhaust port, thereby improving the bass response of the speaker. Furthermore, to ensure the bass response, the ratio of the passive radiator's area to the speaker diaphragm area must be between 1.5 and 2, and the total area of ​​the exhaust port must be approximately equal to the area of ​​the passive radiator.

[0004] However, existing speakers have large vents with fixed locations, making them relatively difficult to design and manufacture. Summary of the Invention

[0005] This utility model provides a speaker that aims to solve the problems of existing speakers having large exhaust vent areas, fixed positions, and complicated design and manufacturing processes.
