Abstract
The invention relates to an external oriented microphone device of mobile phone which can be connected to headset jack or communication terminal port in using, belonging to acoustic pick-up field about the mobile phone. The structure of the external microphone assembly respectively arranged through holes in front of and in back of the oriented microphone for serving as plug socket for the connection of the external microphone assembly and headset jack or communication terminal port of the mobile phone. The oriented microphone device of mobile phone can furthest improve speech quality even in noisy talking environment.
Description
Technical field
The invention belongs to pick-up scope in the mobile phone, a kind of mobile phone oriented microphone device of the externally positioned type of the use that particularly can be connected with earphone jack or communication port.
Background technology
In the last few years, the popularity rate of mobile phone improved rapidly, and in fact, mobile phone has become a kind of daily necessities of modern.Mobile phone can also provide the transmission service and the multiple Additional Services of various data outside the intrinsic voice call function of maintenance, on function, can deserve to be called multimedia telecom equipment fully.
At present, for the convenience on using, mobile phone has been extensive use of the microphone phone, and that this microphone mainly uses is omnidirectional Mike.Although the use oriented microphone, the quality of mobile phone calling will get a promotion, owing to must all implement to open to Mike's rear and front end, so have certain difficulty.
Shown in Figure 1 is the rate response characteristic of the omnidirectional Mike in the existing mobile phone, and therefrom as can be seen, this omnidirectional Mike has demonstrated identical response output valve for the incident sound source of sound of all directions.In prior mobile phone, owing to be difficult to Mike's rear portion is implemented to open, so can't adopt oriented microphone.Because Mike has made identical reaction to the incident sound source of sound of all directions, so under noisy conversation environment, it is very difficult wanting to improve speech quality.
Summary of the invention
A kind of mobile phone oriented microphone device of the externally positioned type that uses the objective of the invention is to be connected with earphone jack or communication port.It is characterized in that the structure of described externally positioned type Mike assembly 2 comprises, is arranged at the through hole 2A at oriented microphone the place ahead and rear respectively; Be used for the socket 2B that externally positioned type Mike assembly 2 and the earphone jack 3A of mobile phone 1 are connected with communication port 3B.
The oriented microphone device circuit structure of described mobile phone comprises: voice signal is converted to the directed externally positioned type Mike assembly 2 of the signal of telecommunication, the connectivity port 3 that above-mentioned externally positioned type Mike assembly 2 is connected with mobile phone 1; Above-mentioned externally positioned type Mike assembly 2 is monitored with the situation that is connected of connectivity port 3, and export corresponding monitor signal, again Mike's signal of input is transferred to Mike's signal input part 4 of the speaking circuit of mobile phone 1 inside.
The invention has the beneficial effects as follows that the present invention is by a kind of externally positioned type oriented microphone that only can carry out output true to nature and broadcast to the sound of target direction, and it is connected use with earphone jack or communication port, have under noisy conversation environment, also can improve the effect of speech quality to greatest extent.

Embodiment
A kind of mobile phone oriented microphone device of the externally positioned type that the invention provides to be connected with earphone jack or communication port uses.Shown in Figure 2 is the oriented microphone device outward appearance skeleton diagram of mobile phone of the present invention, and as shown in the figure, the structure of externally positioned type Mike assembly 2 comprises: the through hole 2A that is provided with respectively at the place ahead and the rear of oriented microphone; Be used for the socket 2B that externally positioned type Mike assembly 2 and the earphone jack 3A of mobile phone 1 are connected with communication port 3B.
Shown in Figure 3 is the oriented microphone device circuit diagram of mobile phone of the present invention, and as shown in the figure, its structure comprises: the directed externally positioned type Mike assembly 2 that voice signal is converted to the signal of telecommunication; The connectivity port 3 that above-mentioned externally positioned type Mike assembly 2 is connected with mobile phone 1; Above-mentioned externally positioned type Mike assembly 2 is monitored with the situation that is connected of connectivity port 3, and export corresponding monitor signal, again Mike's signal of input is transferred to Mike's signal input part 4 of the speaking circuit of mobile phone 1 inside.
Below, Fig. 4 is elaborated to the present invention with said structure in conjunction with the accompanying drawings.
In externally positioned type Mike assembly 2, the place ahead of oriented microphone and rear are respectively arranged with through hole 2A.Therefore, the characteristics of oriented microphone 2 can be fully played.When the user is in the state of steering vehicle and meeting, if use above-mentioned externally positioned type Mike assembly 2, the socket 2B of externally positioned type Mike assembly 2 can be inserted the earphone jack 3A or the communication port 3B of mobile phone 1, among the embodiment in Fig. 3, connectivity port 3 is earphone jack 3A.If the socket 2B of above-mentioned externally positioned type Mike assembly 2 is inserted the connectivity port 3 of above-mentioned mobile phone 1, because inductor can transfer to the control device of mobile phone 1 inside for the monitor signal of earphone jack, this control device promptly can receive Mike's signal after the connection situation of externally positioned type Mike assembly 2 is discerned.By this method, just can use externally positioned type Mike assembly 2 to converse.
Fig. 4 has shown the rate response characteristic of externally positioned type Mike assembly 2 oriented microphones of the present invention, and we can find that the incident acoustic wave at Mike the place ahead and rear is not identical in reaction.Above-mentioned externally positioned type Mike assembly 2 is better for the about 135 ° wide incident acoustic wave reaction in the place ahead, and suppresses for the noise of rear and side.That is to say that the incident sound wave source at rear weakens the output valve of noise, also improved S/N rate simultaneously the place ahead sound source.
Result of the test shows to have the above-mentioned externally positioned type Mike assembly 2 of orientating function, the speech quality of its 1 meter distance and omnidirectional Mike 1.7 meters apart from the time speech quality suitable.
