  • Patent number: 9258630
    Abstract: A disclosed coaxial audio speaker may include a treble sound unit and a bass sound unit co-axially surrounding the treble sound unit. The bass sound unit may be in form of a single magnetic gap mechanism and have a magnetic-conductive base. The magnetic-conductive base may be with an auxiliary magnetic adjoining space and a coil movement space adjacent to the auxiliary magnetic adjoining space. A magnet, a vibrating vocal tone diaphragm along with a wiring board may be disposed within the coil movement space. A bass vibration audio source point and a treble vibration audio source point may be at the same horizontal level. Therefore, the size of the audio speaker may be reduced. And the broader electricity adjustability may be achieved as the bass vibration audio source point and the treble vibration audio source point may be horizontally aligned.

  • Publication number: 20150373436
    Abstract: A disclosed coaxial audio speaker may include a treble sound unit and a bass sound unit co-axially surrounding the treble sound unit. The bass sound unit may be in form of a dual magnetic gap mechanism and have a vibrating vocal tone diaphragm along with a wiring board. The bass sound unit may further include a magnetic resistant ring selectively disposed therein. Within the magnetic resistant ring lies the treble sound unit. Therefore, the size of the audio speaker may be reduced because of the co-axially disposed bass sound unit and the treble sound unit. And the broader electricity adjustability may be achieved as vibration audio source points of the bass sound unit and the treble sound unit may be horizontally aligned.

  • Patent number: 9210513
    Abstract: A disclosed multi-ring coaxial audio speaker may include a treble sound unit, a first bass sound unit co-axially surrounding the treble sound unit, and a second bass sound unit co-axially surrounding the first bass sound unit. The first bass sound unit, the second bass sound unit, and the treble sound unit may be co-axially disposed with respect to each other. Bass vibration audio source points and a treble vibration audio source point may be at the same horizontal level, to achieve the broader electrical adjustability. The size of the audio speaker may be reduced as well.

  • Patent number: 9210489
    Abstract: The present disclosure provides an off-axial audio speaker using single audio source. The audio speaker includes a bass sounding unit and a treble sounding unit. The bass sounding unit is off-axially surrounded by the treble sounding unit and includes two magnets, a single magnetic gap mechanism, a vibration sounding membrane disposed with a single sound coil, and a wiring board. A magnetic resistance ring is selectively disposed within the bass sounding unit, and the treble sounding unit is disposed in the magnetic resistance ring. The vibration audio source point of the bass sounding unit is horizontally aligned with the vibration audio source point of the treble sounding unit. Therefore, the size of the audio speaker can be reduced, and vibration audio source points are aligned for realizing a relatively broader range of electrical adjustability and enabling the audio speaker to output both bass and treble sound.

  • Patent number: 8744111
    Abstract: An earphone with tension diaphragm includes a front portion, a rear portion, a silicone gel earplug, a filtering net and a sound generating unit. As a user pushes the earphone into his ear, the diaphragm of the sound generating unit has a deformation and thus an air turbulence would be generated. This air turbulence would then cause a deformation of the tension diaphragm and this deformation would in turn eliminate the strange and unpleasant noises generated as a user pushes an earphone into his ear. Therefore, better audio signals may be achieved and a better low-frequency effect may be reached. Also, because the earphone of the present invention is water-resistant, it may be used under water. In addition, other water-resistant earphones on the market do not have such tension diaphragm.
