In recent years, the "driver war" in the acoustic market seems to be more and more drastic. People are trying to cram more and more drivers into their earphones, which can help them increase the retail price and get more profit. While, frankly speaking, this doesn’t improve the sound quality. And, the engineers in Concept Audio know this situation clearly.

Concept Audio has developed some new high-quality drivers, including small drivers for built-in ear monitors and big drivers for headphones. As of today, we have obtained more than 30 patents, and about 18 patents are awarded for the drivers developed by our own core technologies.

And, we keep working out more good solutions for our customers, to help them develop their exclusive flagship models.

Here, we will list some information about drivers for your reference. For more detailed solutions, please feel free to contact us!

Features

 

1. This dual dynamic driver is equipped with a brand new drive unit that has two sets of independent electric rings, and coaxial unit surrounded by ring magnet design. One unit has the function of low frequency, the other one dynamic response and high frequency. In this case, these two units match each other perfectly to achieve a win-win goal.

2. With patented design, this professional dual dynamic driver unit not only keeps its natural low frequency but also possesses quick dynamic response of balanced armature.

3. Vocal is designed to be fine and smooth, which will make the harmony between the human voice and the background sound at the climax. The bass is perfectly developed. Moreover, there is no too harsh high frequency. All in all, the three frequencies equally shared this sound design.

4. In order to offer a richer and higher quality sound performance to users, we apply a multiple-tuned damping technology when designing this driver unit. By using this technology, we have successfully made the sound details of this driver increased to a higher level.

Dual Dynamic + 1 BA Hybrid Driver

Features

 

1. With patented design of dual-coil technology, we enable this driver to contain as much vibration modules as possible. In this way, the cavity can be as smaller as possible.

2. To show the distinctiveness of this dynamic driver, we adopt a balanced armature which is equipped with higher performance of high-frequency and compact size. Therefore, we can maximize the volume of the earphone to offer more possibilities in sound tuning.

3. We have our own unique design of three frequencies. As for the low frequency, we apply copper coil in order to explore deeper possibility for improving the sound quality. Moreover, to improve high frequency extension, we use aluminium coil for this driver unit. In the end, the balance armature is designed for the treble part, which can make up the deficiency of high-frequency extension of the dynamic driver unit.

4. In order to provide better and more advanced sound performance, our experienced and professional tuners specially adjust the external electronic fractional frequency circuit. By making this adjustment, users can enjoy greater sound details.

Features

 

1. This driver adopts a light-weight coil, which helps the whole system to keep lighter than other drivers with the same size and improves the treble response notably.

2. The high frequency of above 3.5kHz of the product is more exquisite than that of other dynamic drivers.    

3. The product, using the multi-tuned damping technology, features higher-quality sub-bass, and also keeps the rich vocal in the upper range of the bass spectrum.

4. This 10-millimeter driver is light and small, and can aid your IEM in creating more exquisite and spatial sounding.

5. We also call it full-range driver or Hi-Res driver.

 

Solutions

  1.  

    1. This driver features a great sound if it is used to develop a single driver earphone.

    2. Working with a balanced armature driver, it can give a richer sound effect.

Dual Bass Driver

 

Specification

 

Driver type: Dynamic

Driver size: 10mm

Frequency response: 20--20k Hz

Impedance: 84 Ohm +/- 15%

Sensitivity: 95dB+/-3dB at 1kHz

Rated power: 1 mW

contact us >

Features

 

1. The combination of newly designed diaphragm and coil improves the performance of bass, which helps form a better dip.

2. The updated magnetic circuit design improves the driver’s vibration amplitude and features a bigger undistorted output power.

3. To some extent, the new coil design has a greater ability to allow the low voice current to pass and carry a higher load power.

 

Solutions

 

1. This driver can present well-controlled sub-bass.

2. This driver can work with a balanced armature driver to get a richer sound effect.
