Abstract
The utility model relates to a mobile phone, particularly a mobile telephone with a wireless handsfree function. The utility model is characterized in that the inner side of back cover of the mobile phone is provided with a transmission receiving opening device comprising a wireless sending and receiving control unit; the transmission receiving opening device can extend a signal inserting and connecting terminal line to the external side of the back cover; when the back cover is buckled on the back part of the mobile phone, the signal inserting and connecting terminal line can be inserted and connected to an earphone hole of the bottom of the mobile phone; thus, signals received by the mobile phone can be sent to the wireless sending and receiving control unit through the signal inserting and connecting terminal line; the wireless sending and receiving control unit and a wireless earphone bidirectionally transfer, send and receive signals; thus, the mobile phone can achieve the functions of non electric wire trouble, portability and handsfree through being matched with the wireless earphone.
Description
Technical field
The utility model relates to mobile phone, more particularly, relates to a kind of mobile phone with wireless hands-free function.
Background technology
From beginning in 1998, many well-known 3C manufacturers began to add the home control network communication protocol of formulating a Bluetooth by name (blue bud).And blue bud biggest advantage has been to overcome the restriction of distance and connectable unit number.Control by program, blue bud device can be selected (or refusal) specific device and make line, its function future except can be used as computer and periphery, computer is connected the media with computer, can also be as the control media of mobile phone and computer, mobile phone and Handless, various IA household electrical appliances etc.Therefore, general mobile phone can design towards this radio transmitting device mostly, and the mobile phone collocation uses the Handless of blue bud technology to be paid attention to by the consumer gradually.
Though this hardware with blue bud technology has been rough ripe product, present many manufacturers are too high except the single-chip unit price cost because of blue bud, or industry to the integration of this respect also in the middle of test, so present such product also is not a lot.Therefore, high frequency, digitized blue bud technology is not full-fledged as yet and commercialization before, the user of mobile phone has to earlier to use with the Handless of wired earphone under for electromagnetic fear appeals.The wired Handless of tradition still has its some inconveniences on using, for example earphone cord is intertwined etc. easily.
Summary of the invention
The technical problem that will solve of the present utility model is, utilizes lower cost that the existing mobile phone that does not possess the wireless hands-free function is improved, and makes it have wireless carry-on hold-free handset function.Certainly when blue bud technology maturation and reasonable price, also can take high frequency, digitized blue bud technological means.
The present invention is achieved through the following technical solutions, construct a kind of mobile phone with wireless hands-free function, it is characterized in that, in the back of the body of described mobile phone lid, be provided with a transmission interface device, described transmission interface device can and a wireless type earphone between form two-way signal transmission transmitting-receiving;
Described transmission interface device is located at the medial surface of described back of the body lid, comprises wireless receiving and dispatching control unit and signal grafting end line, and described signal grafting end line can reach its outside in described back of the body lid;
Described wireless type earphone is by being provided with members such as a wireless receiving and dispatching control unit, battery, microphone and loud speaker in the earphone base that can plug in ear at, again with a capping cover form.
After back of the body lid is fastened on mobile phone, this signal grafting end line can be plugged in the earpiece holes of mobile phone bottom, make signal that mobile phone receives be passed to the wireless receiving and dispatching control unit by the signal end line of pegging graft, and do two-way signal transmission transmitting-receiving by this a wireless receiving and dispatching control unit and a wireless type earphone, make mobile phone can arrange in pairs or groups this wireless type earphone and reach the carry-on hold-free handset function that no electric wire is impeded.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the schematic perspective view that mobile phone and Qi Beigai are decomposing state;
Fig. 2 is the wireless type earphone exploded perspective view that the utility model is arranged in pairs or groups and used;
Fig. 3 is a user mode schematic perspective view of the present utility model.
Each figure number is simply described as follows in the accompanying drawing: the 1st, and mobile phone; The 11st, back of the body lid; The 12nd, earpiece holes; The 13rd, slot; The 14th, switching piece; The 15th, slot; The 2nd, transmission interface device; The 21st, the wireless receiving and dispatching control unit; The 22nd, signal grafting end line; The 3rd, the wireless type earphone; The 31st, earphone base; The 32nd, the wireless receiving and dispatching control unit; The 33rd, battery; The 34th, microphone; The 35th, loud speaker; The 36th, capping; The 4th, the communication identification card.
Embodiment
As shown in Figure 1, a kind of mobile phone with wireless hands-free function mainly is that the back of the body at mobile phone 1 covers 11 inner faces and is provided with a transmission interface device 2, and make transmission interface device 2 can and a wireless type earphone 3 between form two-way speech sound signal transmission transmitting-receiving.
Wherein, transmission interface device 2 is located at the back of the body and cover 11 medial surface, comprises a wireless receiving and dispatching control unit 21 and the signal grafting end line 22 be made up of wireless two-way reflector and receiver, and this signal grafting end line 22 can cover 11 bottom and reaches outside it from carrying on the back.
The decomposition texture of wireless type earphone 3 as shown in Figure 2, as can be seen from the figure, this earphone 3 is by being provided with members such as a wireless receiving and dispatching control unit 32, battery 33, microphone 34 and loud speaker 35 in the earphone base 31 that can plug in ear at, again with a capping 36 cover form.Wireless receiving and dispatching control unit 32 is except that converting the wireless signal from transmission interface arrangement 2 to sound signal and from loud speaker 35 outputs, also can will being converted to wireless signal and be back to transmission interface device 2 by the sound signal that microphone 34 received.
Utilize above-mentioned member, as shown in Figure 3, when the back of the body covers 11 buckle closures after mobile phone 1, the end line 22 of signal can being pegged graft is plugged in the earpiece holes 12 of mobile phone 1 bottom, the speech sound signal that this mobile phone 1 is received can be passed to wireless receiving and dispatching control unit 21 through signal grafting end line 22, and do two-way speech sound signal transmission by this wireless receiving and dispatching control unit 21 and wireless type earphone 3 and receive and dispatch, make mobile phone 1 have the function of Handless.
