Abstract
The utility model relates to a paper bowl loudspeaker box which is formed by a paper bowl (1), a resonance chamber (2), a voice coil (4), an annular magnet (5) and a soft iron core column (6). The paper bowl (1) is fixed on the resonance chamber (2). One voice coil (4) is arranged on a bottom of the paper bowl. The soft iron core column (6) is fixed in the resonance chamber (2). The annular magnet (5) is fixed on the soft iron core column (6) and maintains a certain gap with the soft iron core column (6). The voice coil (4) is in the gap. The voice coil (4) forms output connection with a power amplifier (3). After the power amplifier (3) is used to input an amplified signal current into the voice coil (4), the voice coil (4) generates a corresponding displacement under an effect of a magnetic field line between the annular magnet (5) and the soft iron core column (6). The paper bowl (1) generates vibration because of the displacement of the voice coil (4) so that an electric signal is reverted to a sound signal.
Description
Technical field
The utility model relates to a kind of audio amplifier, particularly a kind of paper bowl audio amplifier.
Background technology
Audio amplifier is the terminal of whole sound system, and its effect is that the audio frequency electric energy is converted to corresponding acoustic energy, and it is radiated the space.It is the extremely important part of sound system, because it is being undertaken and the signal of telecommunication is transformed into acoustical signal is directly listening to so mission critical for people's ear, it is wanted directly and people's the sense of hearing is come into contacts with.Loud speaker is an important part in the audio amplifier, also is a part of the easiest damage, and common audio amplifier generally adopts the structure and material of structure more complicated to make, and the cost of Zhi Zuoing is not higher with interest than higher like this.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple and easy, paper bowl audio amplifier easily, can with very low cost produce can operate as normal audio amplifier, interest is also very strong.
For solving the problems of the technologies described above, paper bowl audio amplifier of the present utility model is made up of paper bowl, resonant tank, voice coil loudspeaker voice coil, annular magnet, soft iron stem stem.The paper bowl is fixed on the resonant tank, and the bottom of paper bowl has a voice coil loudspeaker voice coil, soft iron stem stem to be fixed on resonant tank inside, and annular magnet is fixed on the soft iron stem stem and with the soft iron stem stem and keeps a fixed gap, and voice coil loudspeaker voice coil is in the space.
Adopt after such structure, feed in voice coil loudspeaker voice coil and amplify later signal code, under the magnetic line of force effect between annular magnet and the soft iron stem stem, voice coil loudspeaker voice coil can produce corresponding displacement, and the displacement of voice coil loudspeaker voice coil will make the paper bowl shake, thereby the signal of telecommunication is reduced into acoustical signal.Paper bowl in the daily life can be sounded this phenomenon interest also than higher.The utility model is simple in structure, and is with low cost, practical and convenient, solved common speaker production cost than higher, interesting not strong problem.
Description of drawings
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
A kind of execution mode schematic diagram of Fig. 1 the utility model paper bowl audio amplifier.
Embodiment
Paper bowl audio amplifier shown in Figure 1 is made up of paper bowl 1, resonant tank 2, power amplifier 3, voice coil loudspeaker voice coil 4, annular magnet 5, soft iron stem stem 6.Paper bowl 1 is fixed on the resonant tank 2, and the bottom of paper bowl has a voice coil loudspeaker voice coil 4, soft iron stem stem 6 to be fixed on resonant tank 2 inside, and annular magnet 5 is fixed on the soft iron stem stem 6 and with soft iron stem stem 6 and keeps a fixed gap, and voice coil loudspeaker voice coil 4 is in the space.Voice coil loudspeaker voice coil 4 links to each other with power amplifier 3 outputs.
When the utility model uses, after utilizing power amplifier 3 to feed the later signal code of amplification for voice coil loudspeaker voice coil 4, under the magnetic line of force effect between annular magnet 5 and the soft iron stem stem 6, voice coil loudspeaker voice coil 4 can produce corresponding displacement, and the displacement of voice coil loudspeaker voice coil 4 will make paper bowl 1 shake, thereby the signal of telecommunication is reduced into acoustical signal.The utility model is simple in structure, and is with low cost, practical and convenient, solved common speaker production cost than higher, interesting not strong problem.
Certainly, this paper bowl 1 can also adopt other papery daily necessitiess that is suitable for, such as dixie cup.Such conversion all falls within the protection range of the present utility model.
