Description
Technical field
The present invention relates to audio amplifier.
Background technology
The audio amplifier of prior art, the music playback frequency band of single loud speaker has certain width, usually can't satisfy the so wide scope of people's ear 20-20kHz fully, therefore, bass, high-pitched driver need to be installed simultaneously, to obtain relatively wide frequency range.And for obtaining preferably tonequality, usually in bass drivers one bugle is installed, as being to be to be the structure that discloses a kind of audio amplifier in the patent documentation on May 23rd, 2007 Granted publication day on May 19th, 2,006 200620059127.1 applyings date at application number, the structure that has specifically disclosed this audio amplifier comprises sound box, bass drivers, high-pitched driver and bugle, two bass drivers and a high-pitched driver are installed in the casing, three's axis is positioned on the same perpendicular, and high-pitched driver is between two bass drivers, and the vibrating diaphragm of high-pitched driver and bass drivers is positioned at same perpendicular.After adopting said structure, by two bass drivers and a high-pitched driver, can obtain relatively wide frequency range, and middle bass is synchronous with high pitch, raising tonequality, the sound effect of acquisition uniqueness.Owing to only have the loudspeaker cavity, the bang path of bass is short, and bass is that straight line spreads out of when above-mentioned bugle, therefore, and the weak effect that low frequency is reset.As be to be to be to disclose a kind of bugle in the patent documentation on July 25th, 2007 Granted publication day on May 19th, 2006 at application number 200620059123.3 applyings date, this bugle is horn-like, form the first flare and the second flare in the trumpet-shaped bugle main body, the first and second flares include cardinal extremity and are the horn-like opening of outwards gradually opening by cardinal extremity, the opening of the first and second flares links to each other, and jointly consists of the opening of bugle main body.The opening of the first and second flares consists of by the end face that launches to four direction, wherein the opening of the opening of the first flare and the second flare encloses formation by four inclined-planes, and the first flare be connected flare and connect by one of them adjacent inclined-plane.This structure, at first, it arranges two horn mouths in a bugle main body, improves it and uses function.In addition, bell-mouthed design adopt the four sides cone be the structure of gradually carrying out can keep sound enlarge, can distortion in the process of transmission or reduce the audio quality.But owing to only have the loudspeaker cavity, the bang path of bass is short, and bass is that straight line spreads out of, therefore, and the weak effect that low frequency is reset.
Summary of the invention
The purpose of this invention is to provide a kind of audio amplifier, this audio amplifier can not only obtain wider frequency range, and, replaying bass effective, audio quality better.
For achieving the above object, a kind of audio amplifier comprises casing, and casing is provided with high pitch outlet and bass outlet, in the high pitch exit loudspeaker is installed, and bass drivers is installed in casing, has been connected with bugle on the bass drivers; Described bugle comprises straight end, bending section and flare; Straight end, bending section and flare connect to the bass outlet successively from bass drivers, and the axis of straight end is mutually vertical with the axis of flare; Have the first sound channel in the straight end, be formed with horn mouth at the first sound channel near an end of bass drivers, near the bell-mouthed end of bass drivers greater than away from the bell-mouthed end of bass drivers; Have the second sound channel in bending section, the axis of advancing the sound mouth of the second sound channel is mutually vertical with the sound mouth axis of the second sound channel; Has the loudspeaker cavity in the flare; Described the first sound channel, the second sound channel and loudspeaker cavity communicate.
Said structure is provided with loudspeaker and bass drivers simultaneously, then can obtain wider frequency range after bass and the high mixture of tones.Increased in the prior art straight end and bending section, thereby increased the transmission path of bass, according to formula F c=c/4 * π * L * Ln (S1/S0) as can be known, (wherein Fc represents the cut-off frequency of bugle; C: expression speed of sound; L: the length of expression bugle; S1 represents the aperture area of bugle; S0: the throat area of expression bugle.), the transmission path of bass in bugle is long, and then cut-off frequency is large, so that replaying bass is effective.In addition, owing to be provided with bending section, in bending section, formed the first crooked sound channel, when bass when the first sound channel, the second sound channel transfer are in the loudspeaker cavity, the axis of advancing the sound mouth of the second sound channel is mutually vertical with the sound mouth axis of the second sound channel, then in the second sound channel reflection and refraction can occur, thereby optimize bass tonequality, thereby improved a bass quality.Have again, at the first sound channel horn mouth is set, so that bass can more be transferred in the first sound channel, improve the utilance to bass.
As improvement, in the loudspeaker cavity, be provided with dividing plate, dividing plate comprises that the cross section of advancing the sound guide section is pre-large post-small taper into sound guide section and go out the sound guide section, the cross section that goes out the sound guide section is pre-small post-large taper, advances the sound guide section and goes out the sound guide section and be connected.This structure is separated into two parts by dividing plate with the loudspeaker cavity, like this, can improve and use power; And dividing plate is arranged to two sections, and two sections all tapered, like this, advance the sound guide section and can smoothly bass be derived, be diffused going out sound guide section place bass, with respect to prior art, the tonequality of bass is better.
As improvement, the cross section of loudspeaker cavity is square, and advancing the sound guide section is 9 degree with relative flare inwall angulation.
As improvement, the first supporting bracket and the second supporting bracket are installed in casing, the first supporting bracket is provided with the first through hole, the second supporting bracket is provided with the second through hole, one end of the first supporting bracket is fixed on the casing, the other end of the first supporting bracket is between bass drivers and straight end, the first through hole communicates with the first sound channel, one end of the second supporting bracket is fixed in the casing, the other end of the second supporting bracket is between straight end and bending section, and the second through hole communicates with the first sound channel and the second sound channel.This structure is utilized the first supporting bracket and the second supporting bracket, can better fix straight end, bending section and flare, and the three is firmly linked together.
As improvement, the large end of flare is provided with the edge, and front surface and the rear surface at edge are parallel to each other; The edge is fixed on the casing that is positioned at the bass outlet.
