Abstract
The utility model discloses signal magnification assisting equipment which comprises an electromagnetic transducer and a bracket which fixes the electromagnetic transducer. The signal magnification assisting equipment is characterized in that the electromagnetic transducer is fixed by the bracket. After the bracket is put into a magnetic tape cabin of a cassette recorder or a videocorder, the recorder or the videocorder can lie in normal broadcasting state, and one magnetic signal emission side of the electromagnetic transducer and one magnetic signal receiving side of the cassette recorder or a videocorder magnetism head lie in an effective position which generates electromagnetic induction. The utility model can be used for a mobile phone hand-free device. A domestic cassette recorder is available indoors, a walkman is available outdoors, and a vehicle-mounted cassette recorder is available in the vehicle. The utility model can effectively avoid influence of electromagnetic radiation of mobile phones on a human body. The utility model is used for an assisting amplifying equipment and can magnify music of the walkman and MPS through a loudspeaker or sonic equipment of the cassette recorder and can receive more better audition effect. The utility model can magnify talk voice using a microphone through an audio system of the domestic recorder and is used for a lecture of a public meeting or a great celebration.
Description
[technical field]
The utility model relates to a kind of device that utilizes cassette recorder that signal is amplified, and belongs to the electronic signal process technical field.
[background technology]
In daily life and production and scientific practice, there are many occasions will need faint signal to amplify, to make it to be converted into the value signal that people can utilize or analyze.Need will play back after the amplification of the signal in walkman, MP3, the mobile phone such as people, perhaps need to utilize the stereo set of home recorder to hold the speech of great rally or sing Karaoke, be worth expensive special-purpose public address equipment and default.
Car and mobile phone become the basic tool in people's work and the life gradually, it is often relatively more dangerous to answer the call when driving, though can solve some problems with earphone, the user tends to leave behind earphone, or when calling, insert earphone again while driving, very dangerous.The vehicle-carried hands-free telephone device complex structure of mobile phone special use, costing an arm and a leg, is the part luxury goods for the general user.
[utility model content]
At present the prior art that small-signal is amplified is quite advanced, but all needs complicated, expensive special equipment, does not have actuality for daily life and general production scientific practice.
The utility model amplifies servicing unit for the technical scheme that solves above technical problem and adopt for a kind of signal is provided, it is characterized in that electromagnetic transducer fixed by support, after making that this support is put into the tape deck of cassette recorder or video tape recorder, the magnetic signal emitting side of electromagnetic transducer just in time is in the active position of generation electromagnetic induction with the magnetic signal receiver side of cassette recorder or video recording head.
The described electromagnetic conversion device that signal described in the utility model amplifies servicing unit is head, video recording head or custom-designed electromagnetic induction device.After the structural design of described support can make it to put into the tape deck of recorder, recorder can be in the normal playback state, and the signal emitting side of described electromagnetic transducer just in time is in the active position of generation electromagnetic induction with the signal receiver side of recorder playback head; After the structural design of described support also can make it to put into the tape deck of video tape recorder, video tape recorder can be in the normal play state, and the signal emitting side of described electromagnetic transducer just in time is in the active position of generation electromagnetic induction with the signal receiver side of video tape recorder broadcast magnetic head.The shape of described support can be for being respectively Fig. 1, Fig. 2 and rectangle, hexagon or octagon shown in Figure 3.
The utlity model has signal is carried out pretreated adapter circuit, to increase the fidelity after signal amplifies.The input of adapter circuit is connected with the signal lead-in, and its output is connected with electromagnetic transducer.
The device that utilizes cassette recorder that signal is amplified provided by the utility model, its ingenious electromagnetic induction principle that utilizes, family expenses cassette tape recorder that generally has by people or video tape recorder are enlarged into faint signal can perhaps can drive display device or stereo set as strong signal with its by people by the useful signal that self sense organ carries out perception and judgement.
The utility model can be used for the hands-free device of mobile phone, and at the indoor family expenses cassette recorder that utilizes, the open air can utilize walkman, and Che Nei can utilize vehicle-mounted cassette recorder, can effectively avoid the influence of the electromagnetic radiation of mobile phone to human body.
Loud speaker or stereo set that device described in the utility model can pass through the music of walkman, MPS cassette recorder amplify, and receive better auditory effect.
The utility model is used for auxiliary public address equipment, can utilize the sound system of home recorder that voice is amplified by microphone, is used for the speech of public meeting or great celebration, and is in order to be effective and do not increase expense.
[description of drawings]
The described support that Fig. 1 signal described in the utility model amplifies servicing unit is a rectangular configuration;
The described support that Fig. 2 signal described in the utility model amplifies servicing unit is a hexagonal structure;
The described support that Fig. 3 signal described in the utility model amplifies servicing unit is an eight-sided formation.
[specific embodiment]
One, as the vehicle carried mobile phone hands-free device
The utility model is used for a kind of mobile phone hands-free device based on vehicle audio and comprises shell 1, electromagnetic transducer 2, adapter circuit 3, microphone 6, input lead 4 and plug 5.The profile of shell such as Fig. 1, Fig. 2 or shown in Figure 3.Plug 5 is inserted on the earphone interface of mobile phone, and audio signal enters the adapter circuit 3 that is positioned at shell by input lead 4, drives electromagnetic transducer 2 then and produces magnetic field.The user inserts vehicle-mounted tape player to this device, and the plug on its input lead 45 is inserted the earphone socket of mobile phones, this moment, the audio signal of mobile phone just outputed to the adapter circuit 3 that is positioned at this apparatus housing by earphone socket and input lead 4, drove electromagnetic transducer 2 then and produced magnetic field.Magnetic field is induced tone currents by the playback head of vehicle-mounted tape player, broadcasts from automobile audio after vehicle-mounted recorder amplifies.The incidental adapter circuit 3 of present embodiment is made up of the resistance of two deamplifications.Microphone 6 inserts mobile phones by input lead 4, and the user can be placed on microphone 6 any position of putting wanted, to reach best communication effect.
Two, as amplifying auxiliary equipment
Under the situation of special-purpose public address equipment useless, the utility model can utilize home recorder and sound system thereof as amplifying auxiliary equipment.The audio signal that microphone is produced because of speech is as input signal, through being input to electromagnetic transducer described in the utility model after the adapter circuit preliminary treatment, the playback head generation electromagnetic induction of electromagnetic transducer and cassette recorder, the tone currents that produced of induction are put in advance through recorder at different levels and are amplified the rear drive stereo set with power amplifier and send sound through amplifying.
In addition, loud speaker or stereo set that the described device of utility model also can pass through the music that walkman, MPS play cassette recorder amplify, and receive better auditory effect.
