1. Field of the Invention
The present invention generally relates to a horn amplifier, more particularly to a horn amplifier that transforms spherical sound waves to plane sound waves via inner paths, and the plane sound waves are able to lower high-frequency attenuation of outputting sound waves.
2. Description of the Prior Art
Nowadays, people gradually put their focus on how to promote their life due to raising consumers' abilities, more particularly to leisure life. While at the moment of physical and mental fatigues, listening music via sitting or lying is the best lifestyle for releasing pressures.
Consumers will generally listen to all kinds of wonderful music in concert halls or performance venues, and a general concert hall or performance venue will use horn speakers to play music. Since the horn speaker applies natural physical theories, it is the most advanced speaker compared to other types of speakers. In practice, the horn speaker uses vibrations to produce sound waves and then transmits the sound waves to remote via a corn member so as to let remote audiences listen music very clear.
Although the prior horn speaker is capable of amplifying and transmitting sound to remote, and manufacturers design many different kinds of inner structures in order to promote sound pressures, such horn speakers may cause lowering high-frequency attenuation. Therefore, to design a horn amplifier that is able to increase sound pressure and improve the problem of high-frequency attenuation will be a best solution.
The main objective of the present invention is to provide a horn amplifier that transforms spherical sound waves to plane sound waves through a plural paths inside thereof, and the plane sound waves are able to lower high-frequency attenuation while in output.
To reach aforesaid objective, a horn amplifier comprises a horn and at least one speaker member with at least one spherical sound source; wherein the horn has one throat portion and one voice port opened from the throat portion toward outside, the bottom surface of the inner side of the throat portion of the horn has an open, the spherical sound source of the speaker member connects with the open, the inner side of the throat portion has at least one S-type sound-guide board, the sound-guide board is made as a plurality of paths in order to let spherical sound waves from the spherical sound source of the speaker member enter into the paths, then the spherical sound waves are transformed into plane sound waves, the plane sound waves are delivered to outside through the inner structure of the horn.
In practice, the S-type sound-guide board is assembled by two guide board.
In practice, the case of the throat portion is shaped as S-type, the inner side of the throat portion has two S-type walls.
In practice, the two sides of the guide board of the S-type sound-guide board connect with the two S-type walls respectively.
In practice, the spherical sound waves from the spherical sound source of the speaker member enter into the paths made by the S-type sound-guide board, then the spherical sound waves are transformed into plane sound waves so as to lower high-frequency attenuation of outputting the sound waves.
Except above first structure, the sound-guide board can be another structure. The horn amplifier comprises a horn and at least one speaker member with at least one spherical sound source; wherein the horn has one throat portion and one voice port opened from the throat portion toward outside, the bottom surface of the inner side of the throat portion of the horn has an open, the spherical sound source of the speaker member connects with the open, the inner side of the throat portion has at least one D-type sound-guide board, the sound-guide board is made as a plurality of paths in order to let spherical sound waves from the spherical sound source of the speaker member enter into the paths, then the spherical sound waves are transformed into plane sound waves, the plane sound waves are delivered to outside through the inner structure of the horn.
In practice, the D-type sound-guide board is assembled by two guide board.
In practice, the case of the throat portion is shaped as S-type, the inner side of the throat portion has two D-type walls.
In practice, the two sides of the guide board of the D-type sound-guide board connect with the two D-type walls respectively.
In practice, the spherical sound waves from the spherical sound source of the speaker member enter into the paths made by the D-type sound-guide board, then the spherical sound waves are transformed into plane sound waves so as to lower high-frequency attenuation of outputting the sound waves.
Except above two structures, the sound-guide board can be another structure. The horn amplifier comprises a horn and at least one speaker member with at least one spherical sound source; wherein the horn has one throat portion and one voice port opened from the throat portion toward outside, the bottom surface of the inner side of the throat portion of the horn has an open, the spherical sound source of the speaker member connects with the open, the inner side of the throat portion has at least one <-type sound-guide board, the sound-guide board is made as a plurality of paths in order to let spherical sound waves from the spherical sound source of the speaker member enter into the paths, then the spherical sound waves are transformed into plane sound waves, the plane sound waves are delivered to outside through the inner structure of the horn.
In practice, the <-type sound-guide board is assembled by two guide board.
In practice, the case of the throat portion is shaped as S-type, the inner side of the throat portion has two <-type walls.
In practice, the two sides of the guide board of the D-type sound-guide board connect with the two <-type walls respectively.
In practice, the spherical sound waves from the spherical sound source of the speaker member enter into the paths made by the <-type sound-guide board, then the spherical sound waves are transformed into plane sound waves so as to lower high-frequency attenuation of outputting the sound waves.
Other and further features, advantages, and benefits of the invention will become apparent in the following description taken in conjunction with the following drawings. It is to be understood that the foregoing general description and following detailed description are exemplary and explanatory but are not to be restrictive of the invention. The accompanying drawings are incorporated in and constitute a part of this application and, together with the description, serve to explain the principles of the invention in general terms. Like numerals refer to like parts throughout the disclosure.
The objects, spirits, and advantages of the preferred embodiments of the present invention will be readily understood by the accompanying drawings and detailed descriptions, wherein:
Following preferred embodiments and figures will be described in detail so as to achieve aforesaid objects.
With reference to
The major difference between the horn amplifier of the present invention and regular horn speakers is the structure of the sound-guide board 113. As shown in
From the view of structure, there are differences between the horn amplifier of the present invention and the three prior horn speakers. Hence, for high-frequency attenuation, directivity and Q value, the three prior horn speakers and the horn is amplifier of the present invention are measured.
Compared to other prior arts, the present invention has the advantages listed below. The present invention promotes the sound pressure and improve the high-frequency attenuation. More, is the present invention is lack of the disorder of the positivity of the directivity of any prior art. So the horn amplifier of the present invention is able to approach the functions that the prior arts can not have.
Although the invention has been disclosed and illustrated with reference to particular embodiments, the principles involved are susceptible for use in numerous other embodiments that will be apparent to persons skilled in the art. This invention is, therefore, to be limited only as indicated by the scope of the appended claims
