Summary of the invention
Technical problem to be solved in the utility model is, a kind of compact conformation, stable performance, reliability height and the strong vibration sounding multifunction device of vibration force when vibration are provided, when this device is installed on portable terminal such as the mobile phone, can switch according to the signal of peripheral commutation circuit, answer the needs of different occasions, bear multinomial functions such as calling vibration prompting, caller voice prompting or call voice output respectively.
Adopted following technical scheme for solving the problems of the technologies described above the utility model: provide a kind of vibration sounding multifunction device, comprise: vibrating diaphragm and the voice coil loudspeaker voice coil mutually bonding with described vibrating diaphragm, by pole piece and magnet and place the magnetic circuit system that the bowl-shape magnetic conductor of described magnet constitutes, by the vibration unit that described magnetic circuit system and stopping means constitute, hang at least one elastic sheet of described vibration unit; Described vibrating diaphragm and elastic sheet are supported by shell; The bottom top is provided with the supporting limiting gasket of stopping means.
At least one elastic sheet central authorities that suspended vibration described in the utility model unit is used are by hollow out, and described vibration unit is placed on wherein, and elastic sheet constitutes vibrational system with vibration unit.Described vibration unit is made of with magnetic circuit system a stopping means, on bowl-shape magnetic conductor stopping means is set.Described stopping means extends between described limiting gasket and the bottom, and the amplitude of vibration unit is controlled within the preset range.Described limiting gasket is arranged near under the described elastic sheet above the bottom.
Bowl-type magnetic conductor described in the utility model central authorities are placed with the magnet that is covered with pole piece, form the annular magnetic gap between magnet and the bowl-type magnetic conductor, and the voice coil loudspeaker voice coil that is bonded with vibrating diaphragm is inserted in the middle of the magnetic gap.Then be with one on the excircle of bowl-type magnetic conductor bottom and be higher than the spacing ring flange that the metal of iron is made with proportion, magnetic circuit system, retaining washer, spacing ring flange and elastic sheet constitute vibrational system together.The outer rim of ring flange extend between bottom and the limiting gasket.Feed frequency in the described voice coil loudspeaker voice coil when being higher than the alternating signal of 200Hz or audio signal, prompting note, music or voice that output is predetermined.When feeding the low-frequency alternating signal in described voice coil loudspeaker voice coil, the resonance frequency of vibrational system is at 157 ± 5Hz.
Owing to adopted technique scheme, vibration sounding multifunction device described in the utility model compared with prior art, structure is compact more, performance is stable more, reliability is higher and when vibration vibration force stronger, when this device is installed on portable terminal such as the mobile phone, can switch according to the signal of peripheral commutation circuit, answer the needs of different occasions, bear multinomial functions such as calling vibration prompting, caller voice prompting or call voice output respectively.
