Abstract
The utility model discloses a small woofer, which comprises speakers and speaker accommodating cavities, wherein the speakers are accommodated in the speaker accommodating cavities, and the speaker accommodating cavities are provided with sound outlets. The small woofer also comprises bass cavities which are communicated with the speaker accommodating cavities, wherein a brass opening is respectively arranged at one side of each brass cavity exactly opposite to the speaker. Since the brass cavities communicated with the speaker accommodating cavities are additionally arranged, and the brass opening is respectively arranged at one side of each brass cavity exactly opposite the speaker, the sound from the speakers enters the brass cavities to oscillate backwards and forwards to form brass, and the circulated and oscillated brass is transmitted from the brass opening arranged at one side of each brass cavity exactly opposite the speaker, accordingly, people feel that the sound from the speakers is powerful and has shocking effect extremely. The utility model also discloses a music player with the small woofer.
Description
Technical field
The utility model relates to a kind of audio amplifier, relates in particular to a kind of audio amplifier that can produce bass effect.
Background technology
Along with the continuous progress of science and technology, the electronic product of energy playing back music such as consumer electronics product such as mp3 player, mp4 player, music phone and notebook computer obtains development at full speed, and the popularity rate height.
Along with improving constantly of people's living standard, the continuous quickening of rhythm of life, people not only wish to realize " walkman ", wish just can carry with oneself a kind of audio amplifier especially with better acoustical quality, so just can hear melodized, the outstanding music of the button popular feeling anywhere or anytime, such as onboard, in the dining room, before when stroll, match etc. in anxiety, utilize music to relax.Music itself just can allow the people passionate, but music needs audio amplifier to play back as carrier, for people's taste and appreciation.If good again music speaker effect is poor, then the music that plays out by this audio amplifier will lose original style, embody the not intension of music itself.Along with masses' having deep love for to music, people like moulding with music the sentiment of oneself after the leisure, want to mould oneself with simple and honest music strong, that have the shock effect, and can produce this simple and honest strong, sound equipment with shock effect sound, small-sized woofer becomes first-selected product.
At present on the market, the audio amplifier that maximum generation bass effects occurs is exactly the closed audio amplifier.So-called closed audio amplifier is exactly loudspeaker to be installed in the casing of a complete closed form audio amplifier, and this audio amplifier utilizes casing that the acoustic radiation before and after the loudspeaker is separated, to prevent acoustic short circuit.Because the air in the closed audio amplifier has certain damping action simultaneously to the motion of loudspeaker, therefore resonance frequency and the quality factor to audio amplifier has certain influence, and the audio amplifier volume increases then can reduce above-mentioned influence.But, since carry electronic product that class has a music playback function for people easy to carry and practicality, that volume can be done is as much as possible little.Therefore the size of audio amplifier and can utilize the space of putting also relatively to be limited to; And the loudspeaker of the audio amplifier that the space is limited to will certainly reduce the performance of loudspeaker greatly, the sound dullness of sending, dry and astringent, especially bass part can manifest, can make the music of broadcast lack bass effect, make and listen the hearer and can't feel the simple and honest strong and shock effect of music, cause the generation of distortion phenomenon.Therefore, it is most important to improve the design of audio amplifier.
Therefore, the utility model provides a kind of simple in structure, volume is little and bass effect is outstanding small-sized woofer that is applicable to common loudspeaker.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, volume is little and bass effect is outstanding small-sized woofer that is applicable to common loudspeaker.
Another purpose of the present utility model is to provide a kind of music player, the small-sized woofer that is applicable to common loudspeaker that described music player has is simple in structure, volume is little and bass effect is outstanding.
For achieving the above object, the technical scheme that the utility model provides is: a kind of small-sized woofer is provided, comprise loudspeaker and loudspeaker containing cavity, described loudspeaker are placed in the described loudspeaker containing cavity, described loudspeaker containing cavity has sound mouth, wherein, also comprises the bass chamber, described bass chamber and described loudspeaker containing cavity connect, and described bass chamber has the bass opening over against a side of described loudspeaker.
Preferably, described sound mouth is located on the loudspeaker containing cavity on a side of loudspeaker, and sound mouth is better propagated over against the sound that loudspeaker help sending in the loudspeaker, reduces the loss of the sound that loudspeaker send.
Preferably, described bass chamber is greater than described loudspeaker containing cavity, and a bigger space of sound of sending to loudspeaker vibrates, thus make the bass that sends more simple and honest strong, have a shock effect.
Preferably, described bass chamber is rectangular, and the sound that loudspeaker send shakes at one and vibrates in the space that equates, the bass of generation is more coordinated.
The utility model music player comprises housing, movement, control part and small-sized woofer, described movement and small-sized woofer are placed in the described housing, described control part is placed on the described housing, described control part and described small-sized woofer electrically connect with described movement respectively, small-sized woofer comprises loudspeaker and loudspeaker containing cavity, described loudspeaker are placed in the described loudspeaker containing cavity, described loudspeaker containing cavity has sound mouth, wherein, described small-sized woofer also comprises the bass chamber, described bass chamber and described loudspeaker containing cavity connect, and described bass chamber has the bottom opening over against a side of described loudspeaker.
The utility model compared with prior art, owing to increased the bass chamber that connects with described loudspeaker containing cavity, and described bass chamber has the bottom opening over against a side of described loudspeaker, make the sound that sends from loudspeaker enter into the circulation vibration formation bass that carries out in the bass chamber back and forth like this, the bass of circulation vibration blazes abroad from the bottom opening over against a side of described loudspeaker, thus the people feel sound that loudspeaker sent simple and honest strong, have a shock effect.
