Abstract

The utility model relates to a loudspeaker which comprises a basin rack with basin rack sidewall, a vibration system received in the basin rack for vibrating and sounding, and a magnetic circuit system fixed on the basin rack for driving the vibration system to vibrate and give off sound. The vibration system comprises a diaphragm and a voice coil which drives the diaphragm to vibrate and has a voice coil lead wire, and the magnetic circuit system comprises a magnetic bowl and a magnetic steel which is assembled in the magnetic bowl and forms a magnetic gap with the magnetic bowl. The voice coil is placed in the magnetic gap, and the magnetic bowl is provided with magnetic bowl sidewall where a groove underneath the voice coil lead wire is arranged. The groove penetrates through the magnetic bowl sidewall on the horizontal direction, and has a groove bottom. The distance between the voice coil lead wire and the groove bottom is greater than the maximum amplitude of the diaphragm. The loudspeaker effectively minimizes the possibility of breaking of the voice coil lead wire, and the reliability of the loudspeaker is improved.

[utility model content]
The purpose of this utility model is to solve above-mentioned loud speaker and causes broken string because of voice coil leads shock magnetic bowl sidewall, thereby has a strong impact on the deficiency of loud speaker reliability, and a kind of loud speaker is provided.
a kind of loud speaker, comprise the basin frame that is provided with basin frame sidewall, be contained in the vibrational system that is used for vibration sounding in the basin frame, and be immobilizated on the basin frame for the magnetic circuit system that drives described vibrational system vibration sounding, described vibrational system comprises vibrating diaphragm and drives described vibrating diaphragm vibration and with the voice coil loudspeaker voice coil of voice coil leads, described magnetic circuit system comprises that the magnetic bowl becomes the magnet steel of magnetic gap with described magnetic bowl-type with assembly in described magnetic bowl, described voice coil loudspeaker voice coil is placed in described magnetic gap, described magnetic bowl is provided with magnetic bowl sidewall, described magnetic bowl sidewall is provided with the groove that is positioned under voice coil leads, described groove runs through described magnetic bowl sidewall in the horizontal direction, described groove is provided with bottom land, described voice coil leads is from the distance of the bottom land of the groove peak swing greater than vibrating diaphragm.
Preferably, the quantity of described groove is four and is symmetrical arranged about the central shaft of described magnetic bowl.
Preferably, the bottom land of described groove is provided with to derive to the voice coil leads direction from bottom land and extends boss, and described boss is along extending flange away from the level of magnetic bowl is upwards derivative, and described flange is fixed in the basin frame.
Preferably, described basin frame sidewall is provided with derivative extended from the inboard of basin frame sidewall and is used for the protuberance of the described flange of fixing, and described flange is fixed with the stack of described protuberance.
The beneficial effects of the utility model are: the loud speaker that the utility model provides has effectively reduced the broken string probability of voice coil leads, has promoted the reliability of loud speaker.
[description of drawings]
Fig. 1 is the three-dimensional exploded view of the utility model loud speaker;
Fig. 2 is the cutaway view of loud speaker in Fig. 1;
Fig. 3 is the stereogram that in Fig. 1, loud speaker lacks protecgulum and vibrating diaphragm.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As depicted in figs. 1 and 2, the utility model provides a kind of loud speaker 1, comprise the basin frame 10 that is provided with basin frame sidewall 101, be contained in magnetic circuit system 11 in basin frame 10, be immobilizated in basin frame 10 vibrational system 12, be immobilizated in basin frame 10 tops and form protecgulum 13, the weld tabs 14 that is embedded at basin frame 10 and the listening help circle 15 of receiving spaces with basin frame 10.Described magnetic circuit system 11 comprises that the magnetic bowl 16, the assembly that are contained in basin frame 10 form the magnet steel 17 of magnetic gap and the pole piece 18 that is attached at described magnet steel 17 surfaces with described magnetic bowl 16 in described magnetic bowl 16.Described vibrational system 12 comprises that periphery is immobilizated in the vibrating diaphragm 19 of basin frame 10 and drives described vibrating diaphragm 19 vibrations and with the voice coil loudspeaker voice coil 20 of voice coil leads 201, described voice coil loudspeaker voice coil 20 1 ends are suspended in described magnetic gap, and an other end is immobilizated in vibrating diaphragm 19 belows.Described weld tabs 14 quantity are two and be embedded at respectively in basin frame 10, and the end of a thread of voice coil leads 201 is welded in this weld tabs 14, and weld tabs 14 parts are exposed to the outer surface of basin frame 10 in order to be electrically connected with the external world.Described listening help circle 15 is placed on basin frame 10, and between basin frame 10 and vibrating diaphragm 19.
In conjunction with shown in Figure 3, described magnetic bowl 16 is provided with magnetic bowl sidewall 161 again, and described magnetic bowl sidewall 161 is provided with the groove 162 that is positioned under voice coil leads 201, and the quantity of described groove 162 is four and is symmetrical arranged about the central shaft of described magnetic bowl 16.Described groove 162 runs through described magnetic bowl sidewall 161 in the horizontal direction.Described groove 162 is provided with bottom land 1621, and described voice coil leads 201 is from the distance of the bottom land 1621 of groove 162 peak swing greater than vibrating diaphragm 19.The bottom land 1621 of described groove 162 is provided with from bottom land 1621 to the derivative boss 1622 that extends of voice coil leads 201 directions, because boss 1622 from bottom land 1621 derivative extended and with bottom land 1621 are one, therefore in the utility model, it is the part of bottom land 1621 that boss 1622 also be can be regarded as towards the surface of voice coil leads 201, and voice coil leads 201 is greater than the peak swing of vibrating diaphragm 19 equally towards the distance on the surface of voice coil leads 201 from boss 1622.Described boss 1622 is along extending flange 1623 away from the level of magnetic bowl 16 is upwards derivative, and described flange 1623 is fixed in basin frame 10.
