Abstract
A thin type loudspeaker comprises a sound basin, a suspending edge, a sound loop, an upper magnetic conduction plate, a T-shaped lower magnetic conduction plate and a magnet. The sound loop is adhesively fixed at the center position of the sound basin. The outer edge of the sound basin and the inner edge of the suspending edge is adhered with the outer edge of the suspending edge adhesively fixed on the upper magnetic conduction plate. The magnet is adhesively clipped between the upper magnetic conduction plate and the T-shaped lower magnetic conduction plate. The thin type loudspeaker reduces the height of the loudspeaker appearance by eliminating the sound basin bracket and the elastic wave plate in the traditional loudspeaker to achieve compact structure, high fidelity and sound quality, simplified design and manufacturing process and the reduced producing cost.
Description
One, technical field
The utility model relates to a kind of loud speaker, refers to a kind of Thin-shaped speaker that does not have the sound basin stand and play the ripple plate especially.
Two, background technology
Known loud speaker comprises voice coil loudspeaker voice coil, sound basin, sound basin stand, plays critical pieces such as ripple plate, magnet, magnetic conductive board.The sound basin of known loud speaker is taper, and it is big to take up room, and needs with the sound basin stand it and group of magnets to be installed to together; Play the ripple plate and often be called as spider again, its main application is can the off-center position when guaranteeing the voice coil loudspeaker voice coil vibration.But play the frequency characteristic that the ripple plate is having a strong impact on loud speaker, bring difficulty to design, make complex manufacturing, cost increases.
Three, summary of the invention
The utility model purpose is to provide a kind of simple and compact for structure, cost is low, tonequality is good tone-off basin stand, does not have the Thin-shaped speaker that plays the ripple plate.
The utility model comprises under sound basin, outstanding limit, voice coil loudspeaker voice coil, upper conduction magnetic board, the T shape that magnetic conduction is pulled, magnet.Voice coil loudspeaker voice coil cements on the sound basin, and the outside of sound basin and the inner edge on outstanding limit are bonding, and the outside on outstanding limit cements on the upper conduction magnetic board, the sticking magnet that clips between the magnetic conductive board under upper conduction magnetic board and the T shape.
The utility model is compared following improvement with traditional loud speaker: at first the sound basin changes into plate shaped by traditional taper or ball top shape, directly cements on the upper conduction magnetic board by outstanding limit, has saved the sound basin stand and has played the ripple plate.Save height of contour reduction, compact conformation that the sound basin stand can make loud speaker, be convenient to install, increase the dischargeable capacity of audio amplifier, the vibratory murmur, the magnetic field loss that bring by the sound basin stand have been exempted, reduce production costs: save bullet ripple plate and simplified design and production process greatly, because play the ripple plate tonequality is had material impact, so will spend a lot of time and efforts to go to test and adjust the performance that plays the ripple plate in the conventional loudspeakers production process, the utility model has saved this process.
Secondly the internal diameter of magnetic conductive board, magnet big a lot of than in the conventional loudspeakers under the voice coil loudspeaker voice coil in the utility model, upper conduction magnetic board, the T shape, the back side at the sound basin forms a unlimited space, help the sound wave diffusion, reduce the alt standing wave between sound basin and upper guide plate.The voice coil loudspeaker voice coil of large diameter helps reducing cuts apart the vibration distortion, helps heat radiation.
Thereby the utility model makes compact conformation, is convenient to install by saving the sound basin stand in the conventional loudspeakers and playing the height that the ripple plate reduces the loud speaker profile, reduces distortion, improves tonequality, has simplified design and production process, has reduced production cost.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, specific embodiment
A kind of loud speaker comprises magnetic conductive board 5, magnet 6 under voice coil loudspeaker voice coil 1, sound basin 2, outstanding limit 3, upper conduction magnetic board 4, the T shape.Voice coil loudspeaker voice coil 1 cements on the sound basin 2, and the inner edge on the outside of sound basin 2 and outstanding limit 3 is bonding, and the outside on outstanding limit 3 cements on the upper conduction magnetic board 4, the sticking magnet 6 that clips between the magnetic conductive board 5 under upper conduction magnetic board 4 and the T shape.
The diameter of voice coil loudspeaker voice coil 1 should be big as far as possible, helps reducing and cut apart the vibration distortion and be beneficial to heat radiation.Sound basin 2 for ball top shape, also can adopt plate shaped in this example.Adopt ball top shape during suggestion is produced, ball top shape to cut apart the vibration distortion little, and easily cooperates and forms gravity balance with voice coil loudspeaker voice coil 1, minimizing is bumped and is enclosed the phenomenon generation.The internal diameter of magnetic conductive board 5, magnet 6 should be big as much as possible under upper conduction magnetic board 4 and the shape, so that form open space at the back side of sound basin 2, helps the diffusion of sound wave.
Claims (1)
1, a kind of Thin-shaped speaker comprises under sound basin, outstanding limit, voice coil loudspeaker voice coil, upper conduction magnetic board, the T shape that magnetic conduction is pulled, magnet.Voice coil loudspeaker voice coil cements on the sound basin center, the outside of sound basin and the inner edge on outstanding limit are bonding, the outside on outstanding limit cements on the upper conduction magnetic board, the sticking magnet that clips between the magnetic conductive board under upper conduction magnetic board and the T shape, it is characterized in that described sound basin is a ball top shape or plate shaped, the internal diameter of magnetic conductive board, magnet is bigger under voice coil loudspeaker voice coil, upper conduction magnetic board, the T shape, forms a unlimited space at the back side of sound basin, helps the sound wave diffusion.
