Abstract
The utility model relates to a multifunctional switch type double tracks stereophonic earphone, which is an electroacoustic conversion device which converts the electrical energy into the acoustic energy and is directly coupled with two ears of a person. The utility model can solves the problem of one person occupation and frequency response wasting of the double tracks stereophonic earphone, effectively achieves two persons sharing, and is flexible and convenient. The multifunctional switch type double tracks stereophonic earphone only requires joining in parallel a stereophonic earphone jack [PHONES] on the original double tracks stereophonic earphone, therefore the structure is particular simple, and the multifunctional switch type double tracks stereophonic earphone does not influence on the existing devices and has no particular requirements to the operation of the existing devices. The utility model can render two persons to share the stereophonic sound effect, is flexible and convenient, and does not mutually disturb and influence the other persons.
Description
The utility model relates to a kind of electro-acoustic transducer device that electric energy is converted to acoustic energy.
The electric energy energy transducer is used for the sound of resetting, it is to utilize current to drive the vibrating diaphragm vibration, cause that adjacent air density changes, the air of vibration makes people's ear ear-drum produce corresponding vibration, restore sound, electro-acoustic transducer device is to free space radiation acoustic energy, and people's two ears just can not be heard the stereophonic reproduction effect of original sound truly; Promptly disturb surrounding environment, also be subjected to external interference.Required exciting power is big, and frequency response is narrow, and harmonic distortion is big.
For addressing these problems, common way is to adopt two-channel sterearphone, two-channel sterearphone since about two earphones be independently to change acoustic device, their input signal difference, and directly be coupled with people's ear, utilize binaural effect can hear truly that the level difference of the original sound of two sound channels, phase difference, time difference and tone color difference etc. produce stereophonic effect, but this two-channel sterearphone only can be enjoyed for a people, and its frequency response is generally 20-2OKHz, is enough to share for two people.
The purpose of this utility model is achieved in that plug place at two-channel sterearphone is with lead and connect a stereophone jack promptly: PHONS.Do not influence sound when one people listens to, only need to insert a common two-channel sterearphone at the jack place when two people listen and get final product, its jack plays a part switch.
The utility model because only need be on former device with lead and connect a stereophone jack, so structure is simple especially, simultaneously since contact point not on headset main body, so it to the mode of operation of former device without any special requirement, in addition owing to the stereo jack simple and convenient, so realize the requirement of multi-functional and switch easily.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the practical operation figure according to the multifunction switch type two-channel sterearphone of utility model proposition.
Describe in detail according to concrete operations details and the working condition that the utility model proposes below in conjunction with Fig. 1.
This device comprises a headset plug, 3 pads [1] [2] [3] are arranged in the plug, pad on the one hand with about change the acoustic device formation two-channel sterearphone that is connected, pad welds solder joint [1] with jack leg [6] with jack leg [5], solder joint [3] with jack leg [4], solder joint [2] respectively mutually with lead simultaneously, finishes the feature of functional switch.
Claims (3)
1, electric energy is converted to acoustic energy, and connects the electro-acoustic transducing device of coupling with people's two ears, this device has two people independently to change acoustic device, on its plug next door an earphone jack [PHONS] is arranged, and the plug of earphone jack and this device mutually and connect.
2, device according to claim 1 is characterized by with lead respectively with solder joint [1] and jack leg [4], solder joint [2] and jack leg [5], and solder joint [3] welds mutually with jack leg [6].
3, device according to claim 1, earphone jack and former headset plug also connect, in case insert standby two-channel sterearphone, are connection, unplug to be to close standby earphone electric energy.Do not influence the stereo audio of former device when pushing the back aside equally with access failure.
