Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of passive radiator, is applicable in stereo set, can improve the bass effect of stereo set.
Referring to figs. 1 through Fig. 4, in one embodiment, described passive radiator comprises balancing weight 10 and the vibrating diaphragm 20 of relative both sides being arranged at described balancing weight 10 respectively; The ring 23 that described vibrating diaphragm 20 comprises interior diaphragm 21, extenal fixation ring 22 and is connected between described interior diaphragm 21 and described extenal fixation ring 22, the interior diaphragm 21 being positioned at described balancing weight 10 both sides is tightly connected with described balancing weight 10; The extenal fixation ring 22 being positioned at described balancing weight 10 both sides is tightly connected; Described ring 23 has the opening 230 towards another vibrating diaphragm 20 direction relative with this ring 23 place vibrating diaphragm 20, is positioned at the opening 230 of the ring 23 of the vibrating diaphragm 20 of described balancing weight 10 both sides in the face of arranging.
Should be understood that, when this passive radiator is installed on stereo set, be connected and fixed by extenal fixation ring 22 and stereo set.When music play by this stereo set, can produce sound wave air-flow in the casing of this stereo set, the vibrating diaphragm 20 then in this passive radiator is followed sound wave air-flow and is produced vibration, thus adjusts the bass effect that this stereo set sends.Because vibrating diaphragm 20 Relative Vibration being positioned at balancing weight 10 both sides ensure that the balance of balancing weight 10, therefore, the balance that whole vibrating diaphragm 20 vibrates can be ensured.
Wherein, above-mentioned vibrating diaphragm 20 vibrates in order to respond air pressure, to strengthen the low frequency performance of stereo set.Its material should have excellent damping characteristic, elasticity, linear and easy-adhesion, when using in mini audio amplifier, also should have good thermal stability.Mass is in order to control the Oscillation Amplitude of vibrating diaphragm 20; This counterweight can be the object of any materials, and be preferably metal weights part, in this preferred embodiment, described counterweight is iron block.It is worth mentioning that iron block also has heavier weight at less volume, can conveniently be applied in small size sound equipment, and the cost of iron is relatively low.
The utility model passive radiator arranges vibrating diaphragm 20 by the both sides relative at balancing weight 10, when vibrating diaphragm 20 is vibrated, balancing weight 10 can be made to keep balance, makes sound can not distortion, thus improves the stability of stereo set bass audio.
Be understandable that, in above-described embodiment, the mode that interior diaphragm 21 and balancing weight 10 are tightly connected is not limit, can arrange according to actual needs, such as, ringwise, the annular interior diaphragm 21 being positioned at described balancing weight 10 both sides is fitted and connected with the respective side of described balancing weight 10 interior diaphragm 21 described in the present embodiment.This fixed form, directly interior diaphragm 21 can be pasted on the relative both sides of balancing weight 10, fixed form is fairly simple, easily operates.
Certainly, the mode that interior diaphragm 21 and balancing weight 10 are tightly connected is not limited to this, following a kind of structure at least can also be adopted to replace realizing, particularly, with reference to Fig. 4, between the interior diaphragm 21 of described balancing weight 10 both sides, be formed with the container cavity (figure does not indicate) of accommodating described balancing weight 10.Wherein, interior diaphragm 21 forms a groove near the side of balancing weight 10 to the side of its described balancing weight 10 is dorsad recessed by it, described container cavity is formed, to be fixed in this container cavity by balancing weight 10 after the groove be positioned on the interior diaphragm 21 of balancing weight 10 both sides cooperatively interacts.Just ensure that after installation that balancing weight 10 is tightly wrapped between its both sides inner membrance, make balancing weight 10 make the problem of audio distortions there will not be to tilt in the process swung, thus ensure that the stability of bass.
Based on above-described embodiment, in embodiment further, described ring 23 is provided with at least one venthole 101, as Fig. 1, Fig. 3 and Fig. 4.This venthole 101 is for when vibrating diaphragm 20 vibrates, circulate for the gas in the cavity that two rings 23 are formed is relative with the gas in the casing of stereo set, thus damping when regulating vibrating diaphragm 20 to shake, increase the stability of this passive radiator, reduce the abnormal sound of passive radiator simultaneously.
Wherein, the quantity of described venthole 101 is not limit, and can be one, also can be multiple, and when the quantity of described venthole 101 is multiple, venthole 101 described in each is evenly arranged along described ring 23, to ensure the stability of air-flow, avoids occurring abnormal sound.
The utility model also provides a kind of stereo set, and this stereo set comprises above-mentioned passive radiator; The detailed construction of described passive radiator can refer to above-described embodiment, repeats no more herein; Be understandable that, owing to employing above-mentioned passive radiator in stereo set, therefore, the embodiment of this stereo set comprises whole technical schemes of the whole embodiment of above-mentioned passive radiator, and the technique effect reached is also identical, does not repeat them here.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
