Description

A kind of wireless headset and portable terminal
Technical field
The utility model belongs to wireless communication field, relates in particular to a kind of wireless headset and portable terminal.
Background technology
Portable terminal electromagnetic radiation in use can damage user's health undoubtedly, and wired earphone originally allows the user can avoid close contact with portable terminal in use.Because wired earphone need be connected with portable terminal, and inconvenience is arranged when wearing and converse more, therefore the both hands " liberation " that in fact do not have people come out.
As typical wireless headset, the appearance of bluetooth earphone means really separating of earphone and portable terminal, has solved the problem of portable terminal electromagnetic radiation and " liberation " people both hands to a great extent.Yet, the receiving element of bluetooth earphone (loud speaker) and be subjected to ticket unit (microphone) be make as a whole employing mechanical connection the mode fixed in position together, the overall dimensions of this fixed in position is bigger, often allows the user drop easily when wearing; And, the design of this fixed in position does not consider that different users can not waited by the ticket unit and the distance of user's mouth after wearing bluetooth earphone, therefore can not get rid of because this distance factor causes being subjected to ticket unit received speech signal well when conversation, influence speech quality.
The utility model content
The purpose of the utility model embodiment is to provide a kind of wireless headset, is intended to solve the wireless headset of prior art and wears inconvenience, is subjected to ticket unit received speech signal well, influences the problem of speech quality.
The utility model embodiment realizes like this, a kind of wireless headset, described wireless headset comprises discrete radio telephone receiver and wireless receiver, wherein, described radio telephone receiver comprises microphone, speech coding unit that is connected with described microphone and the wireless transmission unit that is connected with described speech coding unit, and described wireless receiver comprises radio receiving unit, tone decoding unit that is connected with described radio receiving unit and the loud speaker that is connected with described tone decoding unit.
Another purpose of the utility model embodiment is to provide a kind of portable terminal that comprises above-mentioned wireless headset.
The utility model embodiment manufactures two independent entity that do not have the physics annexation by radio telephone receiver and the wireless receiver with wireless headset, wireless headset is conveniently worn, be not easy to come off, and radio telephone receiver can flexible itself and user's the distance of face, reach best voice signal reception.
Description of drawings
Fig. 1 is wireless headset and the mobile phone annexation figure that the utility model embodiment provides.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Among the embodiment that the utility model provides, the radio telephone receiver of wireless headphone system and wireless receiver are two independent entity, do not have the physics annexation, and both communicate by built-in wireless module and portable terminal.
Wireless headset and portable terminal annexation figure that Fig. 1 provides for the utility model embodiment, wherein, the wireless earphone structure that the frame of broken lines part provides for the utility model embodiment.For convenience of explanation, only show relevant portion with the utility model embodiment.
Consult Fig. 1, microphone 101 is voice signal receiving units of radio telephone receiver 1, is responsible for receiving external sound signal.In order to be issued to maximum acoustics signal to noise ratio in situation closely, clearly transmit voice signal, adopt two-way noise reducing type closely to say microphone among the utility model embodiment.The voice signal that speech coding unit 102 transmits microphone 101 is handled the back by low-pass filtering, mould/number conversion, prediction, fundamental tone extraction, clear/voiced sound correction and parameter coding etc. and is exported audio digital signals, that is, the pulse code modulation sample value with primary speech signal is encoded into a spot of bit (frame) output.Wireless transmission unit 103 is responsible for the audio digital signals of speech coding unit 102 outputs is encoded into the signal that is fit to the wireless mode transmission, is sent to portable terminal 3 by wireless network.Conversation control unit 104 more external operating keys, for example, incoming call is answered key and volume control key (increase and reduce key) etc.When incoming call is arranged, the user presses incoming call and answers key or volume control key, the key commands of conversation control unit 104 outputs is encoded into the signal that is fit to the wireless mode transmission through wireless transmission unit 103, be sent to portable terminal 3 transfers by wireless network, finally form control command at wireless receiver 2 places, the voice output of control loudspeaker 201, volume increase or reduce.Power supply 105 is each circuit devcie power supply such as speech coding unit 102, wireless transmission unit 103 and conversation control unit 104.
In the embodiment that the utility model provides, each components and parts in the radio telephone receiver 1 or circuit module can be integrated on the flexible PCB, and sheathing material and color are optional.Further, radio telephone receiver 1 can be made into different shape according to specifically wearing needs, as the ring shape, can be worn on the finger during use, thereby can flexible itself and user's the distance of face, reach reasonable voice reception.
Wireless receiver 2 comprises loud speaker 201, tone decoding unit 202, radio receiving unit 203, vibration unit 204 and power supply 205.Wherein, loud speaker 201 is voice-output units, be used for the primary speech signal of tone decoding unit 202 decoding outputs is zoomed into the voice signal that suitable people's ear is listened to, simultaneously, loud speaker 201 is exported voice or is regulated volume also according to the key commands of answering key or volume control key from the incoming call of radio telephone receiver 1.Radio receiving unit 203 is used to receive from the incoming call of radio telephone receiver 1 answers the key commands of key or volume control key and the coded voice signal of portable terminal 3.When incoming call, vibration unit 204 sends vibration prompt.The user presses the wireless incoming call of ticket unit 1 that is subjected to and answers key or volume control key, makes loud speaker 201 output voice or regulates volume output.The function of tone decoding unit 202 is opposite with speech coding unit 102, and the course of work is a kind of inverse transformation process, and just process object is another user's voice signal from portable terminal 3.Power supply 205 is loud speaker 201, tone decoding unit 202, radio receiving unit 203 and vibration unit 204 power supplies.
In the embodiment that the utility model provides, vibration unit 204 is entities of being made up of miniature crystal oscillator and related circuit, be in a side of whole wireless receiver 2, avoid loud speaker 201, with radiation proof loud speaker 201 and owing to vibration impacts loud speaker 201.
