The low-pitch loudspeaker is suitable for being applied to an ultra-thin type subwoofer, has good bass effect, can switch to a full-frequency working mode without additionally arranging a high-pitch loudspeaker, can be conveniently installed and used at the bottom of the automobile seat, increases the shortage of bass of an original automobile, and can also directly use the full-frequency working mode.
Description
Technical Field
The utility model relates to a novel high-power coaxial woofer, coaxial woofer has contained independent well bass magnetic circuit sound production system and independent high pitch magnetic circuit sound production system, independent high pitch loudspeaker direct bonding is fixed on well bass basin and voice coil loudspeaker voice coil upper portion, cover well bass magnetic circuit center upper portion, when speaker input signal is in pure bass state, high pitch loudspeaker is out of work, only use as well bass loudspeaker's dust cover function, can effectively improve well bass loudspeaker's low frequency effect, when input signal is full frequency state, well bass loudspeaker and high pitch loudspeaker can independently sound simultaneously.
Background
Most of ultrathin high-power subwoofers in the market at present are only provided with one 8-inch or 10-inch pure woofer, and if the subwoofer is converted into a full-frequency working mode, one or two tweeters are additionally arranged to completely process full-frequency signals, so that the shell of the subwoofer is correspondingly enlarged. And the largest 6.5-inch coaxial loudspeaker installed on the automobile interior door panel in the current market is basically a low-power loudspeaker, has small stroke and low power, has small amplitude when the cone vibrates in work, and is not easy to collide with a high-pitch part, so that the high-pitch loudspeaker can be fixed on a T iron at the center of the medium and low-pitch loudspeaker by a screw rod, but has insufficient bass effect. If design bass is effectual, have the high pitch head, if fix on well bass speaker center T iron with the screw rod, vibration amplitude is big, and high pitch head fixed height is not enough easily bumps the circle, if fixed too high, and whole speaker assembly installs comparatively difficultly on the interior trim door plant of part car.
SUMMERY OF THE UTILITY MODEL
The high pitch loudspeaker is directly adhered and fixed on the upper parts of the cone and the voice coil of the high-power midrange loudspeaker, the specification and the model of the midrange loudspeaker are designed to be more than 6 inches, the rated power is designed to be more than 80W, the high pitch loudspeaker uses a light-weight inner magnetic structure and other light materials, a high-frequency capacitor is arranged in the high pitch loudspeaker, and the total height of the whole loudspeaker assembly can be designed to be less than 70 mm. This coaxial woofer uses in the comparatively ideal of ultra-thin formula subwoofer, and bass effect is good, switches to full frequency during operation, need not to adorn tweeter in addition, and consequently supporting box unit can corresponding design thinner littleer, and whole bass box unit total height can be less than 90mm, and the sound effect ideal can be used in car seat bottom by easy to assemble, increases the bass of former car not enough, also can directly use full frequency mode. The structural design of the utility model comprises the following parts and requirements: 1-heat dissipation hole 2-medium and low voice loudspeaker T iron 3-medium and low voice loudspeaker independent magnet 4-upper splint 5-positioning support 6-fixed basin frame 7-medium and low voice loudspeaker sound production basin 8-medium and low voice loudspeaker voice coil 9-high voice loudspeaker (note: there is independent magnetic circuit sound production system in the inner, high voice loudspeaker and medium and low voice coil are bonded and fixed into one piece)

Detailed Description
The implementation content of the attached drawing 1 is as follows, (1) the heat dissipation holes, because the power of the medium and low pitch loudspeaker is larger, the working time is longer, the internal temperature is higher, in order to guarantee the long-term working stability of the loudspeaker, the high pitch loudspeaker of this design is directly bonded on the upper portion of the center of the medium and low pitch loudspeaker, and is not fixed on the T iron center post by a screw rod, and the central hole of the T iron center post is used as the internal heat dissipation. (2) The T iron (or U iron) of the medium and low sound loudspeaker is formed by stamping common steel according to design requirements, surface treatment and galvanization are carried out, rusting is prevented, a hole is formed in the center for heat dissipation, and magnetic conduction and fixing effects are achieved. (3) The mid-bass loudspeaker magnet can select a high-performance ferrite magnet or a neodymium iron boron magnet according to the requirements of customers or market requirements, and generates a magnetic field after being assembled and magnetized so as to provide the magnetic power for the voice coil to move up and down. (4) The upper clamping plate is formed by stamping common steel according to design requirements, is subjected to surface treatment and galvanization, is prevented from rusting, and plays roles in magnetic conduction and fixation. (5) The positioning support piece is made of cotton cloth materials according to design requirements, plays a role of fixing the voice coil and ensures that the voice coil can work vertically in a certain stroke range all the time without deviation. (6) The fixed basin frame is formed by stamping common steel or die-casting aluminum alloy according to design requirements, is subjected to surface treatment and galvanization, is prevented from rusting, and is fixedly matched and assembled with the whole part. (7) The sound production sound cone of the medium and low sound loudspeaker can select materials such as an aluminum alloy rubber edge, a PP cone rubber edge and the like according to actual use requirements or customer requirements, and has the main function of producing sound by vibration under the driving of the voice coil. (8) The voice coil of the medium and low sound loudspeaker adopts a copper wire to be wound on a circular aluminum framework with specified size according to certain design requirements, and has the main functions that the voice coil generates magnetic field strengths with different sizes after inputting different frequency signals, and the voice coil is driven to move up and down under the interaction of the magnetic field of the magnet. (9) The high pitch loudspeaker adopts high-performance lightweight neodymium iron boron magnet, the casing adopts lighter plastics to make according to certain shape, and the sound membrane adopts silk membrane, embeds a high frequency electric capacity and parallelly connected external signal lead wire with well bass loudspeaker voice coil lead wire together.
