Document Type and Number:
Japanese Patent JP2023108596
Kind Code:
A
Abstract:
To provide a low-cost coaxial speaker with a good performance and a simple structure.SOLUTION: In a magnetic circuit system 2 of a coaxial speaker, a first magnetic gap 24 is formed between a first magnet steel assembly 22 and a top wall of a magnetic bowl 21, and a second magnetic gap 25 is formed between the first magnet steel assembly and a second magnet steel assembly 23, and a side wall of the magnetic bowl. A first vibration system includes: a first diaphragm 31; and a first voice coil assembly at least partially inserted into the first magnetic gap. A second vibration system includes: a second diaphragm 41; and a second voice coil assembly 42 at least partially inserted into the second magnetic gap 25. The first magnet steel assembly includes a first magnet steel. The second magnet steel assembly includes a second magnet steel. The first and second magnet steels are magnetized with the same polarity in a vibration direction of the coaxial speaker, being provided so as to be opposed to each other.SELECTED DRAWING: Figure 6
