The speaker is characterized by: high power, 200-300 W；; High sensitivity, maximum sound pressure level110dB; Good frequency response,
Flat frequency response and excellent transient characteristics.
Unique new technology:
(1) The magnetic pole core of the low-frequency speaker for sound box is quite thick, and it is hollow, and it is embedded with the insert formed by wire cutting. This special
The designed magnetic pole core can reduce the weight of the speaker, which is beneficial to heat dissipation and aims to improve the power tolerance.
(2) As an advanced technology, flat wire voice coil was invented by JBL Company. First for woofers, then for tweeters.
It is also widely used, including aluminum wire and copper wire. Flexible flat cable has high duty cycle and high magnetic gap utilization, aiming at improving sensitivity. According to the test,
Under the same magnetic circuit, the flat wire voice coil can improve the sensitivity by about 1dB compared with the round wire voice coil.
(3) The spherical top unit of titanium diaphragm is also the first success of JBL Company. Young's modulus of titanium material is better than that of aluminum material, and titanium is used.
In the high-frequency loudspeaker with diaphragm, the upper limit of high frequency can be greatly widened and the power capacity can be greatly improved.
(4)SFG symmetrical magnetic field magnetic circuit titanium diaphragm is a patented technology of JBL company. This patented technology ensures the symmetry of the magnetic gap and FB value distribution on the voice coil.
The upper and lower positions are equal, including the structural arrangement of magnetic flux balance, which reduces the inductance and heat conduction of the driving source. Effectively restrain low frequency loss
Really, improve the dynamic bearing capacity and damping characteristics.
