For achieving the above object, the utility model is achieved through the following technical solutions: a kind of earphone-type universal holding-free is listened the cylinder base group, it is characterized in that: it mainly is to be provided with the upper casing of acoustic group and the combination of drain pan that bottom surface central authorities are provided with button hole with one, with a circuit board be provided with fixing wherein; Acoustic group body is located at upper casing one side angle, and be provided with the adjutage that is provided with for sound collection cover, sound collection cover is connected with the conducting tube port that wears, the another port of conducting tube is located in the radio reception device of circuit board, establish a microphone in the radio reception device and be connected with the audio frequency amplifier of circuit board, the output of audio frequency amplifier is connected with the lead of external headphones via a lead.

The output of this audio frequency amplifier is connected with a jack base with jack of being located at drain pan via a lead.

Listen the cylinder base group by a kind of earphone-type universal holding-free of the utility model, overcome the shortcoming of prior art, reached the purpose of above-mentioned creation, need not use specific connector, can reach transmission, the conversion of source of sound signal, the jack base sacrificial vessel that source of sound output can utilize direct-connected earphone or be provided with jack has the tone playing equipment of connection-peg to connect, and is not subjected to the restriction of label, specification and style.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Fig. 7 is the schematic diagram of Handless seat group commonly used.

As Fig. 1 and shown in Figure 3, the utility model mainly is to be provided with the upper casing 10 of acoustic group 11 and 20 combinations of drain pan that bottom surface central authorities are provided with button hole 21 with one, circuit board 30 is provided with is fixed in the inner interblock space.Wherein, the body 12 of this acoustic group 11 is located at upper casing 10 1 side angles, and be provided with an adjutage 13 for sound collection cover 14 settings, and adjutage 13, body 12 are hollow body, wear and its port and sound collection cover 14 connections for conducting tube 15, the another port of conducting tube 15 is located in the radio reception device 40 of circuit board 30.

Above-mentioned radio reception device 40 (seeing also Fig. 2) is established the shell 41 of a sealing, establish the port of a microphone 42 over against above-mentioned conducting tube 15 in inside, audio frequency amplifier set on microphone 42 and the circuit board 30 is connected, the output of this audio frequency amplifier is connected on the jack base with jack 22 32 of drain pan 20 through lead 31, the power supply that foregoing circuit plate 30 is required is to take from the automobile cigarette lighter socket by plug 70.

Above-mentioned upper casing 10 is organized with the seat of drain pan 20 combinations, can make up with one group of seat 50, it is that the button hole 21 button groups of protruding button 51 and drain pan 20 by this group seat 50 form, and purpose is to provide seat to organize facility (corrective action with angle, direction) when being provided with in automobile.

See also shown in Fig. 4,5, mobile phone 80 is arranged on the seat group, and sound collection cover 14 covers are closed on the receiver sound hole of mobile phone 80; So, when answering mobile phone 80, source of sound is collected by sound collection cover 14, and gives radio reception device 40 through conducting tube 15, after the audio frequency amplifier of circuit board 30 gives suitable amplification, gives on the jack base 32 by lead 31 transmission again.

Transmission and conversion through above-mentioned source of sound, make jack base 32 be a kind of shared link, its set jack 22 can provide connection-peg 62 insert groups of a lead 61 formula earphones 60, or provide connection-peg 62 insert groups with lead 61 formula loud speakers 63, the source of sound of answering is play by above-mentioned earphone 60 or loud speaker 63, listened to for the user.As for giving orders or instructions partly that hand-free is answered, adopt the high sensitivity microphone of mobile phone itself to get final product.

By above-mentioned structural configuration as can be known, form by acoustic group 11, radio reception device 40 and conducting tube 15 and circuit board 30, the mobile phone of arbitrary label, style, specification all can be reached effect and the effect that hand-free is listened to, transmit the shortcoming that need can't be shared by the connector transmission signals of specific standard and exempt mobile phone source of sound commonly used.In addition, the jack base with jack 22 32 that the utility model is set provides as tone playing equipments such as earphone 60, loud speakers 63 to connect, and so the jack 32 of this jack base 32 also is the design of a shared output.

As shown in Figure 6, the structure of above-mentioned jack base 32 and jack 22 is removed, and the audio frequency amplifier output of circuit board 30 is connected with the lead 61 of external headphones 60 with lead 31, and be made as one with the seat group, formation earphone type handfree headphones seat group.

The utility model is applicable to that the mobile phone of arbitrary label, style, specification uses, and under the output design of jack base 32 and jack 22, more can provide the tone playing equipment with connection-peg 62 and lead 61 to peg graft uses, effectively solve present mobile phone because of different labels, different size, need to use the shortcoming (especially in the use of connector) of pairing Handless accessory, reach shared, general characteristic.
