ELECTROACOUSTIC TRANSDUCER FOR VEHICLE AND MANUFACTURING METHOD OF THE ELECTROACOUSTIC TRANSDUCER FOR THE VEHICLE
Document Type and Number:
Japanese Patent JP2023146288
Kind Code:
A
Abstract:
To suppress the generation of faults such as peeling of a solder part.SOLUTION: An electroacoustic transducer for a vehicle, comprises: a vibration plate for generating a sound by being vibrated; a coil body that vibrates the vibration plate by which a power is conducted to the coil; a second terminal 50; and a distribution member 48. The second terminal 50 constructs one part of a current path between coil bodies, in which one side includes an engagement concave part to be opened. The distribution member 48 constructs the other one part of the current path between the coil bodies, and includes: an engaged part 52 engaged to the engagement concave part, and a bent part 54 bent to the engaged part 52. An inner peripheral surface of the engaged part 52 and the engagement concave part is bonded via a main bonding part of a solder part 58. At least one part of the bent part 54 and the second terminal 50 are bonded via a sub-bonding part 58B of the solder part 58.SELECTED DRAWING: Figure 5
