Definitions

  • the invention relates to a speaker, with a hollow body-forming housing walls and at least one sound-emitting wall area, for acoustically true-to-life reproduction, especially for the low frequency range, with one or more electro-acoustic transducers, preferably electrodynamic loudspeakers, which are arranged in the housing in the sound radiating wall area , wherein a device for controlling the pressure in the hollow body is provided with valve arrangement, according to the preamble of claim 1.
  • the pressure compensation valve is only the pressure and Temperaturaus-equal to the environment, so in the interior of the hollow body in the longer term high pressure and temperature values can not build up.
  • Loudspeaker boxes are used to reproduce the high fidelity musical sounds called Hi Fidelity.
  • subwoofers for emphasis and amplification of the bass reproduction prevail, which consist of a closed and built-in low body speaker in the body.
  • a 3-way loudspeaker box has the low-, mid- and high-frequency chassis.
  • the chassis receives the electrical signals from an amplifier.
  • the feeding of the loudspeaker coil with changing Voltage causes the coil, which is mounted in a permanent magnet between north and south poles, to become an electromagnet which begins to oscillate in accordance with the electrical impulses.
  • the vibrations of the coil which in turn is connected to the loudspeaker diaphragm, are responsible for the oscillating motion of the diaphragm, which in effect produces the sounds.
  • the chassis are placed in a housing made in particular of hard MDF boards. It is to be expected with some problems that lead to significant loss of sound or even distorted sound.
  • efficiency and harmonic distortion play an important role.
  • the music playback takes place with high efficiency and low distortion. A lot of attention is paid to the acoustic reproduction of clear bass, fine and precise highs and embossed voices.
  • a closed loudspeaker box is of relatively simple construction and constitutes an airtight box, the task of which is to prevent the coincidence of the rearwardly radiated wavefront of the sound transducer and that radiated from the membrane front.
  • the forward and backward movement of the diaphragm in a closed housing due to the effect of compression, causes the trapped air to act as a suspension, increasing speaker resonances and weakening bass response.
  • the pressure of the air trapped in the box changes, namely the air is compressed or expanded.
  • the compressed air continues to have a braking effect on the membrane movement. In the worst case, this leads to deterioration of efficiency and sound distortion.
  • the smaller the housing volume the greater the spring effect of the air and the attenuation of the low bass reproduction.
  • the closed speakers have a lower acoustic efficiency. Low efficiency requires more power from an amplifier, which is usually associated with an increase in the cost of the music system and an undesirable increase in electricity costs.
  • a reflex box uses the rear sound of a sound transducer. This This is achieved by installing one or two pipes on one side of the housing. A properly designed and matched to the construction of the housing reflex tube brings some advantages, which are reflected in a stressed bass response and greater efficiency.
  • the Baxreflex design has less braking effect, even none. This can also be negative when the woofer receives a powerful pulse. In this case, the coil may touch the magnet surface, which could lead to sound degradation and damage to the speaker.
  • Other problems include the annoying vibrations of the box, which strongly affect the sound reproduction, the waves standing in the housing as well as the flow losses in the air tube, which in turn lead to disturbing, sometimes thunderous noises.
  • the housing vibrations are reduced by the fact that the housing is not made of wood, e.g. Spruce, but from more expensive and usually much heavier material such as MDF boards, marble etc. is made.
  • the object of the invention is, overcoming the above-described problems in the prior art, a loudspeaker with much higher efficiency and natural sound reproduction, especially in the low bass area to create at the no disturbing resonances and standing sound waves, for significant deterioration of lifelike music reproduction and even responsible for adulteration can occur.
  • this object is achieved in a speaker according to the preamble of claim 1 by the features specified in the characterizing part of claim 1, namely the fact that the housing of the Lauffeerbox has at least two check valves, one of which as an outlet at pressure increase and the other as an inlet port at Pressure reduction in the hollow body opens. It is particularly advantageous if the non-return valves are controllable in their passage cross-section as a function of the sound pressure or of a sound-pressure-analogue size. Further advantageous developments are specified in the claims 3 to 8.
  • the coordinated work of the valves achieves an optimum pressure, which is slightly more than atmospheric pressure.
  • a construction combines the advantages of both a closed and a bass reflex box, which in turn is reflected in much better and low-loss sound reproduction.
  • the achievable with the present invention further advantages are, in particular, that by the work of the check valves, which is tuned according to the emanating from the speaker diaphragm pressure pulses, a favorable pressure level for the optimal, gentle and distortion-poor operation of the chassis can be achieved.
  • FIGURE shows a simplified schematic representation of a speaker 1, which consists of a housing 2, which is made for example of wood.
  • the loudspeaker box 1 according to the figure is intended for sound reproduction and comprises a housing 2 with front wall 2a, rear wall 2b and cover and bottom wall 2c, 2d. The two side walls are not shown for simplicity.
  • the speaker includes a woofer 3 and a tweeter 4, which are spatially separated from each other by a housing partition 8, so that two housing chambers 2.1 (bass area) and 2.2 (high frequency range) are formed.
  • the speaker 1 is thus designed as a 2-way speaker box.
  • the speaker 1 may also comprise only one or more, in particular 3, speakers.
  • the chassis 3 and 4 are arranged, for example, in the front panel 2a of the housing 2.
  • the bass speaker is designed for approx. 20 - 5000 Hz and the tweeter for approx. 2000 - 20000 Hz.
  • the membrane (not shown in detail) of the "woofer" 3 moves in the direction of the front wall 2a or rear wall 2b.
  • the amount of air trapped in the bass region 2.1 is compressed, which leads to an increase in air pressure.
  • the higher pressure actuates the control unit 6b of the check valve 5b, which - as the air flow arrow f1 illustrates - serves as a pressure-dependent outlet valve and thus can flow out an amount of air.
  • the pressure is lowered.
  • the membrane moves from (3) in the direction of Front wall 2a and causes the air expansion, which is responsible for lowering the air pressure.
  • the lower pressure acts on the control unit 6a of the check valve 5a, which - as the air flow arrow f2 illustrates - serves as a pressure-dependent inlet valve and thus allows an amount of air in the bass range 2.1 einrömen. The air pressure is thus increased.
  • the speaker box 1 in its rear wall 2b via the two openings (9a, 9b) for inserting the check valve assemblies 7a, 5a; 7b, 5b.
  • the openings 9a, 9b are arranged in one of the outer walls 2a, 2b, in the example in the outer wall 2b.
  • a pipe section 7a, 7b is inserted into the openings 9a, 9b, and in the interior of the pipe sections 7a, 7b a check valve 5a, 5b is in each case fluidically connected with these.
  • the loudspeaker box can advantageously be designed as a subwoofer box.
  • the non-return valves (5a, 5b) may also be controllable in their passage cross-section as a function of a sound-pressure-analogue size.
  • the passage cross-section (Q) of the check valves (5a, 5b) is preferably in the range 50 mm 2 ⁇ Q ⁇ 10 4 mm 2nd
