Abstract

The utility model relates to a connector with an echo-cancellation function, which is used to cancel echoes generated between a microphone and the speaker of an electronic device. The connector comprises an electric connector and an echo-cancellation circuit board; wherein, the electric connector is provided with a body, in which two or more than two leaf type contact sheets are arranged; the contact sheets are extended out of the body to form conductive pins; in addition, the front end of the body is provided with a plughole; and the echo-cancellation circuit board, which is arranged on the body, is provided with an echo-cancellation unit and two or more than two connection points which are electrically connected with the conductive pins. When the microphone directly receives signals released or reflected by the speaker of the electronic device, the echo-cancellation unit on the echo-cancellation circuit board can directly cancel the signals in order to avoid the harsh echoes.

Description

Connector with echo cancellation function

Technical field

The relevant a kind of connector of the utility model.

Background technology

Using microphone in the past, when perhaps conversing, excessive or when reflection is received by microphone, this microphone and loudspeaker will produce the ear-piercing sympathetic response sound (echo) when the volume that loudspeaker discharged with hand-free receiver, not only allow user's ear be difficult to receive, also can influence speech quality.

Therefore, in order to eliminate the echo that is produced between microphone and the loudspeaker, great majority are equipped with echo cancellation circuit coupling on microphone or hand-free receiver.Directly receive by these loudspeaker when microphone and to be discharged or during through the signal of reflection, this echo cancellation circuit coupling is directly eliminated this signal, to avoid producing the too ear-piercing sound.

Because echo cancellation circuit coupling directly directly is installed on microphone or hand-free receiver, though can avoid the generation of echo, can also improve speech quality, the price of this product is improved, cause user's burden virtually.

The utility model content

In view of this, main purpose of the present utility model is to provide a kind of sympathetic response sound of eliminating to improve speech quality and the connector with echo cancellation function easy to use.

For reaching above-mentioned purpose, the utility model provides a kind of connector with echo cancellation function, is electrically connected on the motherboard of electronic installation, and this connector comprises: electric connector and echo cancellation circuit coupling plate; Wherein, this electric connector has body, has two or more conductive connecting pins on this body, has patchhole at the front end of this body; This echo cancellation circuit coupling plate is disposed on this body, and electrically connects with described motherboard.

This electric connector is the connector of grafting earphone or microphone, and this body interior has the contact chip of two or more spring-piece types, and this contact chip extends to this body exterior and forms conductive connecting pin.In addition, this patchhole inserts for the plug of microphone, and contacts with two or more contact chips of this body interior.Have the echo cancellation unit on this echo cancellation circuit coupling plate, also be provided with the contact that two or more and this conductive connecting pin electrically connects on this echo cancellation circuit coupling plate.

The utility model is by installing the circuit of echo cancellation on the connector of employed earphone of electronic installation or microphone, can allow the user need not use microphone or hand-free receiver with echo cancellation circuit coupling, general microphone or hand-free receiver can be eliminated the ear-piercing sympathetic response sound that microphone and loudspeaker produce as long as peg graft, when eliminating the sympathetic response sound and improving speech quality, and easy to use, use cost is low.

Embodiment

Relevant detailed description of the present utility model and technological means, existing conjunction with figs. is described as follows:

See also Fig. 1, Fig. 2, be respectively connector of the present utility model and decompose and schematic perspective view.As depicted in figs. 1 and 2, the connector with echo cancellation function of the present utility model comprises: electric connector 1 and echo cancellation circuit coupling plate 2.

This electric connector 1, be the traditional grafting earphone or the electric connector of microphone, this electric connector 1 has body 11, and these body 11 inside have two or more spring-piece type contact chips 14 (as shown in Figure 4), and this contact chip 14 extends to this body 11 outside conductive connecting pins 12 that form.In addition, have patchhole 13 at the front end of this body 11, this patchhole 13 provides the plug of microphone (not shown) to insert, and contacts with two or more contact chips 14 of these body 11 inside.

This echo cancellation circuit coupling plate 2 is disposed on this body 11, has traditional echo cancellation unit 21 on it, and this echo cancellation circuit coupling plate 2 is provided with the contact 22 that two or more and this conductive connecting pin 12 electrically connects.

See also Fig. 3, Fig. 4, be respectively the motherboard connection diagram of connector of the present utility model and electronic installation, and the plug of microphone inserts the top cross sectional view of electric connector inside.As shown in Figure 3, when this electric connector 1 is only used by microphone, electrically connect by the echo cancellation circuit coupling plate 2 of this connector and the motherboard 3 of electronic installation.This electronic installation is a personal computer, or portable electronic device (as notebook computer).

When the user uses microphone 4 radio reception, after the cylindric metal joint 42 of plug 41 front ends of this microphone 4 inserted by the patchhole 13 of electric connector 1, this metal joint 42 contacts with two or more contact chips 14 of these electric connector 1 body 11 inside, when microphone 4 is received sound signal, will reach this motherboard 3 by metal joint 42, contact chip 14 and echo cancellation circuit coupling plate 2 and carry out the sound signal processing.When in microphone 4 uses, the loudspeaker that receive electronic installation discharge or when the signal of reflection, the echo cancellation unit 21 on this echo cancellation circuit coupling plate 2 is directly eliminated this signal, to avoid producing the ear-piercing echo sound.

See also Fig. 5, be the user mode schematic diagram of connector of the present utility model.As shown in Figure 5, this electric connector 1 can be assembled on the notebook computer 5, and this electric connector 1 has earphone and microphone function simultaneously.When the user need converse with the long-distance user by notebook computer 5, can be directly in the patchhole 13 with plug 61 these electric connectors 1 of insertion of earphone 6.After the sound signal that this long-distance user sent is handled by notebook computer 5, reach on the earphone 6 through this electric connector 1, and the sound signal that the user gives orders or instructions will be received by microphone 62, after this electric connector 1 reaches notebook computer 5 internal arithmetics, again sound signal is reached on long-distance user's the computer (not shown).In communication process, microphone 62 is if receive that loudspeaker 51 with notebook computer 5 discharge or when the signal of reflection, the echo cancellation unit 21 on this echo cancellation circuit coupling plate 2 is directly with this signal elimination, to avoid producing the ear-piercing echo sound.
