Abstract
The utility model discloses an electro-acoustic transducer, including a vibration system, a magnetic circuit system and a housing which accommodates the vibration system and the magnetic circuit system. The vibration system includes a diaphragm and a voice coil, the voice coil is provided with a voice coil lead electrically connected to an external circuit, and wherein the side wall of the housing is provided with an open groove for leading the lead of the voice coil out. In the utility model, the side wall of the housing is provided with an open groove for leading the lead of the voice coil out, which is convenient for leading the voice coil out, and lead pressing is prevented during the lead leading process, thereby the assembling efficiency of the product is enhanced.
Description
Technical field
The utility model relates to the electroacoustic field, is specifically related to a kind of electroacoustic transducer of being convenient to along voice coil leads.
Background technology
Electroacoustic transducer involving vibrations system, magnetic circuit system and accommodate the fixedly shell of vibrational system and magnetic circuit system in the prior art, vibrational system comprises voice coil loudspeaker voice coil and vibrating diaphragm, voice coil loudspeaker voice coil comprises the voice coil leads that is electrically connected with external circuit.Usually outer casing bottom is provided with pad, and voice coil leads is electrically connected with the pad of outer casing bottom, and still, in the process that draw the outside, the parts line ball of the easy electroacoustic transducer that goes between makes along the process of line complicated voice coil leads by electroacoustic transducer inside.Therefore, be necessary the electroacoustic transducer of said structure is improved to avoid above-mentioned defective.
The utility model content
The utility model technical problem to be solved provides a kind of electroacoustic transducer, can simplify the suitable Wiring technology of the suitable line of voice coil leads, prevents voice coil leads by line ball, thereby improves the packaging efficiency of product.
To achieve these goals, the utility model provides a kind of electroacoustic transducer, the involving vibrations system; Magnetic circuit system; And the shell of accommodating fixing said vibrational system and said magnetic circuit system, said vibrational system comprises vibrating diaphragm and voice coil loudspeaker voice coil, said voice coil loudspeaker voice coil is provided with the voice coil leads that is electrically connected with external circuit; Wherein, said side wall of outer shell is provided with the fluting that said voice coil leads is drawn.
