The utility model content
Technical problem to be solved in the utility model provides a kind of miniature moving-coil type electroacoustic transducer connecton layout, the mode of vibration of voice coil leads in the time of can improving miniature moving-coil type electroacoustic transducer work, reduce the abnormal vibrations of voice coil leads, avoid voice coil loudspeaker voice coil to produce drawbacks such as different sound, reduce the distortion of miniature moving-coil type electroacoustic transducer, improve the performance of output acoustics.
For solving the problems of the technologies described above, the technical solution of the utility model is: the miniature moving-coil type electroacoustic transducer connecton layout, comprise shell and be installed in the interior voice coil loudspeaker voice coil of described shell, described voice coil loudspeaker voice coil is provided with pair of lead wires, described lead-in wire connects up in described shell, and: the trend along described lead-in wire in the described shell is provided with wiring groove.The lead-in wire wire structures of this miniature moving-coil type electroacoustic transducer, the mode of vibration of voice coil leads when improving miniature moving-coil type electroacoustic transducer work, reduce the abnormal vibrations of voice coil leads, avoid voice coil loudspeaker voice coil to produce drawbacks such as different sound, reduce the distortion of miniature moving-coil type electroacoustic transducer, improve the output acoustical behavior.
As a kind of improvement, two ends of described wiring groove are made as narrow lead-in wire fixed area.Two ends form narrow lead-in wire fixed area can be so that lead-in wire fixing on wiring groove.
As further improvement, described shell is a square structure.The shell of square structure is the utility model embodiment preferred.
As further improving, described wiring groove is arranged on the inboard, two minor axis limits of described shell again.The inboard, two minor axis limits that described wiring groove is arranged on square shell is the utility model embodiment preferred.
As further improving, described lead-in wire is fixed in the described lead-in wire fixed area by a glue.Further fixing by a glue, lead-in wire can not broken away from the wiring groove internal activity, make the fixing more firm of voice coil loudspeaker voice coil.
As a kind of improvement of above-mentioned all technical schemes, described lead-in wire is from the cabling in the raised floor of described voice coil loudspeaker voice coil.The invention is particularly suitable for going between from the voice coil loudspeaker voice coil structure of the lower end outlet of voice coil loudspeaker voice coil.
Owing to adopted the technique scheme design: the miniature moving-coil type electroacoustic transducer connecton layout, comprise shell and be installed in the interior voice coil loudspeaker voice coil of described shell, described voice coil loudspeaker voice coil is provided with pair of lead wires, described lead-in wire connects up in described shell, and: the trend along described lead-in wire in the described shell is provided with wiring groove.The lead-in wire wire laying mode of this miniature moving-coil type electroacoustic transducer, the mode of vibration of voice coil leads in the time of can improving miniature moving-coil type electroacoustic transducer work, reduce the abnormal vibrations of voice coil leads, avoid voice coil loudspeaker voice coil to produce drawbacks such as different sound, reduce the distortion of miniature moving-coil type electroacoustic transducer, improve the performance of output acoustics.

Embodiment
Embodiment one:
As Fig. 1, Fig. 2 and shown in Figure 3, the miniature moving-coil type electroacoustic transducer connecton layout comprises shell 1, voice coil loudspeaker voice coil 2 (known magnetic circuit system and the protecgulum of generally also comprising, the top of voice coil loudspeaker voice coil 2 also is combined with vibrating diaphragm etc.).Shell 1 is a square structure, is provided with wiring groove 11 in the inboard, two minor axis limits of shell 1, and also is provided with fairlead 12 on the shell 1; Voice coil loudspeaker voice coil 2 also is the square structure of corresponding shell 1, and is provided with pair of lead wires 21 in the bottom of voice coil loudspeaker voice coil 2, and lead-in wire 21 is held by described wiring groove 11 and connects up through fairlead 12; A pair of flexible connection piece 3 also is installed on the described shell 1.
Fig. 4 is the vibration schematic diagram behind voice coil loudspeaker voice coil 2 Rotate 180s °, and voice coil loudspeaker voice coil 2 Oscillation Amplitude vertically is shown in A1, and the Oscillation Amplitude of lead-in wire 21 is shown in mark A2.After implementing the invention, lead-in wire 21 can make lead-in wire 21 produce vibration at mark A1 place by wiring groove 11 wirings, rotate at the A2 place, thereby reduced to go between 21 body vibration amplitude, avoided the generation of different sound in the miniature moving-coil type electroacoustic transducer course of work, reduced distortion, improved the acoustical behavior of miniature moving-coil type electroacoustic transducer, and the wire laying mode technology of this lead-in wire 21 is comparatively easy.
