Background technology

In various fields, be extensive use of woofer, electronic product particularly, as the speaker system in the venue stereo sets such as the stereo set in the high-grade limousine, TV station, cinema, sports center, music hall, all is furnished with the woofer unit, with the music effect in the playback system true to nature, perfect, in recent years, development along with digital audio technology, requirement to loud speaker is also harsh more, the defective of traditional woofer is: (one) bass of can not resetting, and its power is little, make it there is not dynamics; (2) narrow dynamic range of music medium and low frequency section, and distortion is big; (3) the compound basin in the vibrational system all is cone shapes of identical radian measure, and it is poor that the intensity of paper awl is low, the compound basin of inhibition is cut apart vibration ability; (4) can not reduce resonance frequency on the vibrating diaphragm etc., the defective in the above-mentioned design is not suitable for especially to supporting in the senior limousine stereo set, and innovation improves the design of woofer, and is imperative.

Summary of the invention

The purpose of the utility model development provides a kind of a kind of woofer that is specially adapted on the senior limousine stereo set.Can solve: the bass composition that () exports in the playback stereo set from woofer, and undistorted; (2) wide dynamic range of music medium and low frequency section; (3) the compound basin intensity height in the vibrational system, the big bass of the power that bears within the specific limits has dynamics and stereovision very much, and the utility model woofer is a kind of woofer that can overcome the conventional loudspeakers defective.

The utility model realizes that by subordinate's step see accompanying drawing 1 or 2, it is made up of vibration, magnetic circuit and support system, and vibrational system comprises compound basin, voice coil loudspeaker voice coil, centring disk; Magnetic circuit system comprises magnetic conduction upper plate, magnet, magnetic conduction sheet-pile; Support system comprises the basin frame, wherein, mutually bonding below magnet above the magnetic conduction sheet-pile round platform, following mutually bonding with the magnetic conduction upper plate above the magnet, it is magnetic circuit system that the bonding back of its three constitutes one, and forms the magnetic gathering throat between the circle in magnetic conduction sheet-pile cylindrical and magnet, at its center, slit voice coil loudspeaker voice coil is housed, it is characterized in that: the compound basin in the described vibrational system is not the cone shape of identical radian measure, be have two radians asymmetric cone-shaped, and the height of compound basin is identical; The position, top of basin frame has reinforcement flower shelves.

Magnetic conduction upper plate, magnet, should be concentric when magnetic conduction sheet-pile three is bonding, with the uniform magnetic gathering throat of formation between the circle in the cylindrical that guarantees magnetic conduction sheet-pile centered cylinder and magnet, the magnetic conduction upper plate.

Advantage of the present utility model and effect, (one) has improved the structural design of the compound basin of loud speaker, and the intensity high energy of paper awl suppresses compound basin cuts apart vibration, and it is big that woofer bears power capacity, and the playback bass is powerful, dynamics is arranged.(2) can reduce the resonance of loud speaker bass unit vibrating diaphragm, reduce the distortion factor, make it≤5%; (3) dynamic range can reach 45～5KHz, and rated output power 35W, maximum power are 45W; (4) sensitivity has had and has significantly improved 〉=85dB, and there are reinforcement flower shelves at the basin frame upper position place of loud speaker, has improved loud speaker integrated support intensity.
