Abstract
The utility model relates to a speaker, which comprises a cone frame, a magnetic circuit system accommodated in the cone frame and a vibration system fixedly arranged on the cone frame. The magnetic circuit system comprises a magnetic bowl assembled on the cone frame and main magnetic steel assembled on the magnetic bowl, the magnetic bowl comprises a magnetic bowl bottom wall, the main magnetic steel is assembled on the magnetic bowl bottom wall, the part of the magnetic bowl bottom wall, opposite to the main magnetic steel, is provided with a groove, and the bottom of the main magnetic steel is embedded in the groove. Since the main magnetic steel part is accommodated in the groove at the center of the magnetic bowl bottom wall in the magnetic circuit system with the new structure, the magnetic field intensity of the magnetic circuit system can be ensured effectively while the thickness of the speaker is not increased. Moreover, the structure is more adaptive to the trend of miniaturization of the speaker, and the acoustic performance of the speaker can be further improved.
Description
[technical field]
The utility model relates to a kind of electroacoustic transducer, relates in particular to the loud speaker in the electroacoustic transducer.
[background technology]
Along with the fast development of wireless telecommunications, Global Mobile Phone is more and more, and people are not limited only to basic conversation to the requirement of mobile phone, more requires the face shaping of traditional mobile phone is proposed more requirements.Especially the arrival in 3G epoch, mobile multimedia technology be development thereupon also, and a lot of mobile phones have multiple amusement function, and like video playback, digital vedio recording, recreation, GPS navigation etc., this requires mobile phone screen increasing, so that better visual experience.The consumer is more and smaller and more exquisite to the volume requirement of electronic product now.Thickness of product is more and more thinner, therefore, makes the product volume inside fewer and feweri, and like this, inner electronic devices and components will be done still less accordingly.
Loud speaker as components and parts important in the electronic product that has multimedia function at present; It is thinner that thickness also need be done, especially in the super-thin electronic product, to the thickness requirement and the strictness thereof of loud speaker; This certainly will cause the inside loudspeakers space very little; Magnet thickness in the magnetic circuit system is thinner, thereby influences magnetic property, has restricted the development of thin speaker.
Therefore, be necessary a kind of new loud speaker to be provided to above-mentioned shortcoming.
[utility model content]
The magnet thickness that the purpose of the utility model is to solve above-mentioned inside loudspeakers is too thin, influences magnetic property, the deficiency that the restriction thin speaker must develop, and a kind of loud speaker is provided.
A kind of loud speaker; Comprise the basin frame, be contained in the magnetic circuit system in the basin frame and be immobilizated in the vibrational system of basin frame; Said magnetic circuit system comprise assembly in the magnetic bowl of basin frame and assembly in the main magnet steel of magnetic bowl, said magnetic bowl comprises magnetic bowl diapire, said main magnet steel assembly is in this magnetic bowl diapire; This magnetic bowl diapire is provided with groove over against the part of main magnet steel, and said main magnet steel bottom is embedded at this groove.
Preferably, said vibrational system comprises that periphery is immobilizated in the vibrating diaphragm and the voice coil loudspeaker voice coil that drives the vibrating diaphragm vibration of basin frame.
Preferably; Said basin frame comprise the long side wall and with the broadside sidewall of said long side wall vertical connection; Said magnetic circuit system also comprises the secondary magnet steel that is arranged between said long side wall and the main magnet steel and is immobilizated in the long side wall, and said secondary magnet steel is positioned on the magnetic bowl diapire and about main magnet steel and is symmetrical set.
Preferably, the magnetic bowl sidewall that said magnetic bowl diapire is upwards derived respectively and extended vertical magnetic bowl diapire from its two short end, said magnetic bowl sidewall butt broadside sidewall.
Preferably, said groove runs through magnetic bowl diapire.
The beneficial effect of the utility model is: the magnetic circuit system of this new construction; Main magnet steel partly is contained in the groove of magnetic bowl diapire central authorities; Under the situation that does not strengthen loud speaker thickness; Effectively guarantee the magnetic field intensity of happy magnetic circuit system, and can more adapt to the microminiaturized development trend of loud speaker, further promoted the acoustical behavior of loud speaker.

Fig. 2 is the cutaway view of Fig. 1 loud speaker;
Fig. 3 is the stereogram that Fig. 1 loud speaker is hidden vibrational system and protecgulum.
[embodiment]
Below in conjunction with accompanying drawing and execution mode the utility model is described further.
As depicted in figs. 1 and 2; The utility model provides a kind of loud speaker 1, comprise basin frame 10, be contained in magnetic circuit system 11 in the basin frame 10, be immobilizated in basin frame 10 vibrational system 12, be immobilizated in the protecgulum 13 of basin frame 10 tops and be embedded the conducting strip 14 in the basin frame 10.Said magnetic circuit system 11 comprise assembly in the magnetic bowl 15 of basin frame 10, assembly in the main magnet steel 16 and the secondary magnet steel 17 of magnetic bowl 15 and the main pole core 20 that attaches said main magnet steel 16 surfaces, said vibrational system 12 comprises that periphery is immobilizated in the vibrating diaphragm 18 and the voice coil loudspeaker voice coil 19 that drives vibrating diaphragm 18 vibrations of basin frame 10.Said thin speaker 1 imports the signal of telecommunication for voice coil loudspeaker voice coil 19 through conducting strip 14, thereby drives vibrating diaphragm 18 vibration soundings.
Said magnetic bowl 15 comprises magnetic bowl diapire 151 and the magnetic bowl sidewall 152 of upwards deriving respectively and extending vertical magnetic bowl diapire 151 from 151 liang of short end of said magnetic bowl diapire.Said main magnet steel 16 assembly are in this magnetic bowl diapire 151; These magnetic bowl diapire 151 parts over against main magnet steel 16 are provided with groove 153; Said main magnet steel 16 bottoms are embedded at this groove 153, and these main magnet steel 16 bottoms and groove 153 interference fits or interference fit, in fact; General magnetic bowl diapire 151 is all extremely thin, so we preferably adopt groove 153 to run through magnetic bowl diapire 151.
As shown in Figures 2 and 3, said basin frame 10 comprise long side wall 101 and with the broadside sidewall 102 of said long side wall 101 vertical connections, said magnetic bowl 15 is contained in basin frame 10 and magnetic bowl sidewall 152 butt broadside sidewalls 102.Said magnetic circuit system 11 also comprises the secondary magnet steel 17 that is arranged between said long side wall 101 and the main magnet steel 16 and is immobilizated in long side wall 101, and said secondary magnet steel 17 is positioned on the magnetic bowl diapire 151 and about main magnet steel 16 and is symmetrical set.Gap between said secondary magnet steel 17 and the main magnet steel 16 is a magnetic gap, and voice coil loudspeaker voice coil 19 1 ends are suspended in this magnetic gap.
Above-described only is the preferred embodiments of the utility model; Should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; Can also make improvement, but these all belong to the protection range of the utility model.
