Description

There is the In-Ear Headphones of many dynamic driving unit
Technical field
The present invention relates to earphone field, is specifically related to insert earphone, particularly to the In-Ear Headphones with many dynamic driving unit.
Background technology
Along with the progress of science and technology, being widely popularized of portable media instrument, it is more widely deployed for personal entertainment such as DAB, video player, MP3 player, personal digital assistant, smart mobile phone and panel computer etc. The internal memory of these equipment is bigger, volume is less, reproduction time is more lasting, and supports multiple DAB and video format. How advanced tube apparatus does not have, and earphone is always up the most convenient and most personalized equipment that audio frequency is play.
Insert earphone is type the lightest in same category of device, converts all electronic signals to audible signal. These earphones have lightweight, volume is little and the feature that is convenient for carrying. But, this earphone generally uses the signal dynamics moving-coil structure that the industry is in daily use, as the basic configuration of insert earphone. Owing to the design of single dynamic driving cannot cover the whole audition bandwidth of people, therefore the bandwidth of these earphones is always limited. The more advanced earphone of other structures uses extra balanced armature speaker to build two-way even three road earphone. These earphones may be provided for very big bandwidth, but builds the costly of this blended sensor system.
Comparatively speaking, the design of two dynamic coil-moving speakers is used to have high performance-price ratio in insert earphone, it is possible to regenerate and design similar spread bandwidth to multiple balanced armature speakers and hybrid speaker. Existing the present inventor works out a multichannel earphone utilizing multiple dynamic driving unit to be formed, and it produces low cost, and has expanded the bandwidth of earphone.
Summary of the invention
Present invention aim to address disadvantages described above, design a kind of multichannel earphone utilizing multiple dynamic driving unit to be formed, it produces low cost, and has high bass and remarkable high frequency extension feature, has expanded the bandwidth of earphone.
It is an object of the invention to be accomplished by:
Having the In-Ear Headphones of many dynamic driving unit, it is insert earphone equipment, and its exterior design can adopt various shape, such as tack shape or collar-shaped. Including the ear casing with holding space and the audio-frequency assembly being arranged in this ear casing, this ear casing front end is cased with ear pad, the multiloop loop system structure that this audio-frequency assembly is made up of multiple dynamic driving unit, this dynamic driving unit is made up of high frequency dynamic driver and Low Medium Frequency dynamic driver respectively, and Low Medium Frequency dynamic driver is formed low middle pitch and passed to the auditory meatus of user by conducting channel. Accommodation space in this ear casing includes voice tube, high frequency dynamic driver is located at the front end of this voice tube, and allow the acoustical signal of low-intermediate frequency to be transferred to auditory meatus from this voice tube, high frequency dynamic driver is arranged on the front end of voice tube, the shortest distance is formed between high frequency dynamic driver and human body ear drum membrane, such arrangement may insure that between high frequency dynamic driver and human body ear drum membrane, the high-frequency loss of sound transmission is minimum, forms the extension of better high frequency. Low Medium Frequency dynamic driver is located at the rear end of this voice tube, Low Medium Frequency dynamic driver is positioned at ear casing center of inside, and being divided into former and later two volume spaces for sound insulation inside ear casing, respectively front sound proof box and rear sound proof box, and on front sound proof box, it is provided with the front acoustic aperture for controlling LF-response, being connected to rear sound proof box by front acoustic aperture, this front acoustic aperture is provided with the perforate leading to human antrum auris, is provided with for the rear acoustic aperture with atmosphere on rear sound proof box.

Inside the first voice coil loudspeaker voice coil, it is provided with the first magnetic guiding cycle, and is connected with first control circuit plate at the first magnetic guiding cycle.
As preferably, being additionally provided with the first antivibrator for controlling high frequency response between described first magnetic guiding cycle and first control circuit plate.
As preferably, being provided with the dirt catcher for preventing foreign object damage the first speaker diaphragm in the first speaker diaphragm front, this dirt catcher edge and the first speaker frame internal edges are along being fastened.
As preferably, described Low Medium Frequency dynamic driver is actually a dynamic pickup converting the electrical signal to acoustical signal. It is positioned at inside ear casing, and its band of operation is controlled by passive change-over circuit, so as to mate with the operation frequency of high frequency dynamic driver, carries out stable transition between driving at two. Described Low Medium Frequency dynamic driver is made up of the second voice coil loudspeaker voice coil, the second magnetic circuit and the second speaker diaphragm being attached on the second voice coil loudspeaker voice coil, this second magnetic circuit by the second magnetic guiding cycle being located at inside the second voice coil loudspeaker voice coil, the second annular magnet and the second speaker of fixation be configured to, and be connected with second control circuit plate at this second speaker frame.Second magnetic guiding cycle, the second annular magnet and the second speaker frame form magnetic gap, when electric current is by the second voice coil loudspeaker voice coil, it interacts with the permanent-magnetic field in magnetic gap, produces innervation on the second voice coil loudspeaker voice coil, the motion of the second voice coil loudspeaker voice coil makes the second speaker diaphragm excitation, then produces sound.
It addition, the sensitivity of the second annular magnet and first annular Magnet matches, provide close sensitivity for two dynamic drivers. Each dynamic headphone uses at different frequency band, it is provided that the bandwidth bigger than single dynamic driving.
As preferably, being additionally provided with the second antivibrator for controlling Low Medium Frequency response between the second speaker frame and second control circuit plate.
As preferably, described second speaker frame is U-shaped shelf structure.
The invention have the advantages that: this patent utilizes the multichannel earphone that multiple dynamic driving unit is formed, design has high frequency dynamic driver and Low Medium Frequency dynamic driver, make earphone have high bass and remarkable high frequency extension feature, play the bandwidth providing bigger for audio frequency. High frequency dynamic driver is arranged on the front end of voice tube, the shortest distance is defined between high frequency dynamic driver and human body ear drum membrane, such arrangement may insure that between high frequency dynamic driver and human body ear drum membrane, the high-frequency loss of sound transmission is minimum, forms the extension of better high frequency. And, after the low-intermediate frequency acoustical signal that the altofrequency acoustical signal sent when high frequency dynamic driver and Low Medium Frequency dynamic driver send mixes in hearer's auditory meatus, make sound channel more steadily and more big bandwidth. Meanwhile, its simple in construction, produce low cost, it is simple to be widely popularized.
