Detailed Description

It is to be understood that the terminology, the specific structural and functional details disclosed herein are for the purpose of describing particular embodiments only, and are representative, but that the present invention may be embodied in many alternate forms and should not be construed as limited to only the embodiments set forth herein.

The utility model is described in detail below with reference to the figures and alternative embodiments.

As shown in fig. 1 and 2, as an embodiment of the present invention, an active noise reduction earphone is disclosed, which includes a housing 100 and a control module 200; the housing 100 includes a front case 110 and a rear case 120, the front case 110 and the rear case 120 being connected; the rear housing 120 comprises a top surface 121 and a side surface, the control module 200 is disposed on the top surface 121, and the side surface is provided with an active noise reduction sound emission hole 123.

In the conventional active noise reduction earphone, an active noise reduction sound receiving hole 123 is formed in the top surface 121 of the rear shell 120, and the active noise reduction sound receiving hole 123 is used for allowing external noise to enter the earphone so as to perform active noise reduction after analysis of the earphone. However, the control module 200 is further disposed on the top surface 121 of the rear housing 120, the active noise reduction sound emission hole 123 is too close to the control module 200, and when a user touches the control module 200 with a finger, the active noise reduction sound emission hole 123 is easily blocked, so that a sharp howling sound is generated, and user experience is affected.

According to the active noise reduction earphone, the active noise reduction sound receiving hole 123 is arranged on the side face of the rear shell 120, is far away from the control module 200 and is not in the same plane, when a user touches the control module 200 with fingers, the user operates the top face 121 of the rear shell 120, the active noise reduction sound receiving hole 123 is not easily blocked by the fingers, sharp howling is not easily generated, and user experience is better.

The earphone of the utility model is an active noise reduction earphone. The Active Noise Control (ANC) earphone works on the principle that a microphone collects external ambient Noise, then a system converts the external ambient Noise into a sound wave with opposite phase, and the sound wave is applied to a horn end, and finally the sound heard by human ears is as follows: the environmental noise + the opposite-phase environmental noise, thereby two kinds of noises superpose and realize the noise reduction in the sense organ.

Specifically, the side surfaces of both sides of the rear housing 120 are provided with active noise reduction sound emission holes 123. In this scheme, the side of rear shell 120 both sides all is provided with initiative noise reduction sound receiving hole 123, and the effect of radio reception is better more comprehensive. In other embodiments, the active noise reduction sound emission hole 123 may be provided only on one of the two sides of the rear case 120.

More specifically, the active noise reduction sound emission hole 123 is located at an upper end portion of the side surface. In this scheme, will initiatively fall and make an uproar the sound receiving hole 123 setting is in the upper end of side is close user's ear hole position more, and the ambient noise of its collection is close the noise of income ear more, and the earphone falls initiatively according to the radio reception analysis of initiatively falling the sound receiving hole 123 and makes an uproar and more have a pertinence, and the effect of initiatively falling the noise is better. In other embodiments, the active noise reduction acoustic hole 123 may be disposed at other positions. More specifically, the active noise reduction sound emission hole 123 is flat. The flat active noise reduction sound receiving hole 123 can be arranged in a limited space of the earphone, and the active noise reduction sound receiving hole 123 is larger, so that noise reception is better and easier.

Further, the active noise reduction sound emission holes 123 on the side surfaces of the two sides of the rear shell 120 are communicated; a sound inlet hole 124 is formed in the active noise reduction sound receiver, and the sound inlet hole 124 penetrates through the rear shell 120 to communicate with the inside of the active noise reduction earphone. After the external noise enters the active noise reduction sound receiving hole 123, the noise can be better guided into the earphone through the sound inlet hole 124. More specifically, the active noise reduction earphone includes a circuit board 300, the circuit board 300 being mounted on the front case 110; the circuit board 300 is provided with a sound passing hole 310; the acoustic pass hole 310 is aligned with the acoustic input hole 124; a sound receiving device for receiving ambient noise is disposed on a side of the circuit board 300 opposite to the sound inlet hole 124, and the sound receiving device is located at the sound passing hole 310. The sound receiving device is arranged on the side of the circuit board 300 opposite to the sound inlet hole 124, and the space is larger. By providing the sound passing hole 310 with the sound passing hole 310, the sound inlet hole 124 and the radio aligned, external noise can be introduced into the radio device very well. The sound receiving device can be a sound receiving microphone and the like.

Further, the front case 110 is provided with a partition 111; the position of the partition 111 corresponding to the sound receiving device is provided with a groove 111 a. In the scheme, the position of the partition board 111 corresponding to the sound receiving device is provided with the groove 111a, and the groove 111a plays a role of avoiding, so that the sound receiving device is convenient to mount and also plays a role of positioning the sound receiving device.

More specifically, the active noise reduction acoustic tuning hole 123 is a feedforward acoustic tuning hole. When the active noise reduction earphone is used for noise reduction, the noise reduction is divided into feedforward noise reduction and feedback noise reduction. When the noise is detected by feedforward noise reduction, only the noise is reported to a noise reduction circuit, and then other noises are monitored continuously. When the feedback is used for reducing the noise and detecting the noise, the noise is firstly processed and then monitored.

Specifically, the control module 200 is a touch panel, which is convenient for a user to touch. More importantly, the control module 200 disposed on the top surface 121 is a touch panel, and a user can control the touch panel with only a single finger when touching. In contrast, with the push-button control module 200, a user is generally used to hold the side of the rear housing 120 with another hand in order to exert a force when pushing a button. Thus, the active noise reduction sound receiving hole 123 is easily blocked by a finger pinching the side surface, and a sharp howling sound is generated, which affects user experience.

Specifically, the touch panel is located at an upper end portion of the top surface 121. For setting up the lower tip at top surface 121, touch panel sets up the upper end at top surface 121, and the finger of touch-control is at this position application of force touch-control, and the ear can play the effect of atress bearing, and the earphone of wearing among user's earhole is difficult to atress perk or not hard up.

The foregoing is a more detailed description of the utility model in connection with specific alternative embodiments, and the practice of the utility model should not be construed as limited to those descriptions. For those skilled in the art to which the utility model pertains, several simple deductions or substitutions can be made without departing from the spirit of the utility model, and all shall be considered as belonging to the protection scope of the utility model.
