Description
Nov. 29, 1938. J. A. voLK SPEAKER BAFFLE BALL Filed not. 22, 195e Patented Nov. 29, 1938 UNITED lSTATES PATENT OFFICE 3 Claims.
This invention relates to a speaker baffle ball, and has for the primary object the provision of a device of this character which will efliciently operate from a suspended position Within large or small halls, auditoriums, churches, etc., and Where the placing of speakers of conventional type is impractical and diiiicult from a standpoint of good coverage and appearance.
With these and other objects in View, this invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and acompanying drawing, in which Figure 1 is a vertical sectional View illustrating a speaker baille ball constructed in accordance with my invention.
Figure 2 is a bottom plan view illustrating the same.
Referring in detail to the drawing, the numeral I indicates a substantially semi-spherical shaped casing or shell constructed of any material suitable for the purpose and has an opening to admit electrical conductors 2 of a speaker 3 and also a suspension cable 4 attached to the speaker, as shown at 5. The casing or shell I has a series of perforations 6 and also arranged within the casing or shell is a lining 'I of felt or any other material suitable for the purpose and which extends outwardly of the shell or casing. The lining 1 is of substantially semi-spherical shape.
Detachably secured to the casing or shell is a substantially semi-spherical shaped support 8, which will when applied and secured to the casing or shell cooperate therewith to provide a spherical body, as indicated in Figure 1. The support is provided with sound openings 9 and supports a sound board IU, the latter being suitably secured to the support 8, as shown at II. The sound board has the usual sound opening I2 over which is positioned the cone I3 of the speaker 3. Brackets I4 are arranged between the speaker 3 and the sound board I0. The lining 1 abuts the sound board, as clearly shown in Figure `1 by extending into the support from the shell I.
A conical-shaped element I5 is carried by the support 8 and is detachably secured thereto, as shown at I6. The element I5 protrudes through the opening I2 of the sound board I0 and terminates within the cone I3. The apex of the element I5 is located adjacent to the usual diaphragm of the speaker. The element I5 acts to 'distribute the sound from the speaker through the openings 9 and is preferably constructed of wood or may be made of any other material suitable for the purpose. The casing or shell I, as Well as the support 8, may be constructed of any material suitable for the purpose. The perforations in the shell are to permit a natural leakage of air through said shell which tends to equalize the air pressure within the shell with the air outside of the shell. The lining I is employ-ed in the shell to act as an absorption means which effectively reduces the reflection from the inside Wall of the shell to a minimum so as not to be detrimental to the action of the speaker.
A device of the character described may be readily supported in a suspended position and is capable of eilicient coverage and neat in appearance and is specially useful where speakers of conventional construction are impractical or difficult for use.
Having described the invention, I claim:
1. A speaker baille ball comprising a substantially semi-spherical shaped shell, a speaker in said shell, a lining extending into said shell and covering the inner wall of the shell and conforming to the latter, a support secured on the shell and receiving therein a portion of the lining, and a sound board secured on said support and abutting the lining and having the speaker mounted thereon.
2. A speaker baille ball comprising a substantially semi-spherical shaped shell, a speaker in said shell and including a cone, a lining extending into said shell and covering the inner wall thereof and conforming to the contour of said shell, a substantially semi-spherical shaped support secured on the shell and receiving a portion of the lining, a sound board secured on said support and abutting the lining and having the speaker mounted thereon, said sound board having an opening with the cone of the speaker positioned thereover, said support having sound openings, and means carried by the support and extending through the sound opening of the sound board and terminating within the cone of the speaker to distribute sounds through the sound openings of the support.
3. A speaker baille ball comprising a substantially semi-spherical shaped shell, a speaker in said shell and including a cone, a lining extending into said shell and covering the inner wall thereof and conforming to the contour of said shell, a substantially semi-spherical shaped support secured on the shell and receiving a portion of the lining thereon, a sound board secured on said support and abutting the lining and having the speaker mounted thereon, said sound board having an opening with the cone of the speaker positioned thereover, said support having sound openings, and a conical-shaped member mounted on the support and extending through the sound opening of the sound board with its apex end terminating within the cone of the speaker and acting to distribute sounds from the speaker through the sound openings of the support.
