When the speaker is assembled, the housing 102 composed of the outer rear cover 102a and the earpiece cover 102b encloses the rest of the components. The front cover 116 is assembled in the middle opening 102c of the receiver cover 102b and has a plurality of sound output holes 116a for sound output.

Referring to fig. 2, fig. 2 is a perspective view of a part of components of a speaker according to an embodiment of the invention. The range partition 104 is assembled on the frame 112 to separate a high-pitch chamber and a low-pitch chamber.

The voice domain partition wall 104 is composed of a top wall 104a and a plurality of side walls. The sidewalls are further divided into planar sidewalls 104c and curved sidewalls 104 b.

The frame 112 has ribs 112a to define a central through hole 112b and a plurality of side through holes 112 c. When the gamut partition 104 is combined with the frame 112, the gamut partition 104 covers the central through hole 112b and a portion of the side through holes 112c of the frame 112. In the present embodiment, the central through hole 112b is a circular through hole, and the side through holes 112c are fan-shaped through holes, but not limited thereto.

Referring to fig. 3, fig. 3 is a perspective view of a soundfield partition wall of the speaker of fig. 2. The tweeter chamber 103 surrounded by the register walls 104 includes an electromagnetic circuit element receiving area 103a and a plurality of discrete chamber extensions 103 b. The electromagnetic circuit component accommodation area 103a is used to accommodate the electromagnetic circuit component 106, so that the function is named.

In the embodiment of fig. 3, the high-pitched sound chamber 103 defined by the sound range partition 104 includes 3 discrete sound chamber extension areas 103b, and the electromagnetic circuit component receiving area 103a is a circular area, and the discrete sound chamber extension areas 103b are sector areas, but not limited thereto.

The discrete chamber extensions 103b of tweeter chamber 103 and electromagnetic circuit element receiving area 103a are in spatial communication with one another, e.g., fluid can flow through electromagnetic circuit element receiving area 103a and between discrete chamber extensions 103 b.

Referring to fig. 1 to 4, fig. 4 is a perspective view of a sound generating unit in a speaker according to an embodiment of the invention (the sound generating unit is shown with a housing removed). When the speaker is assembled, the electromagnetic circuit element receiving area 103a of the treble chamber 103 is aligned with or covers the central through hole 112b of the frame 112, and the discrete chamber extension area 103b of the treble chamber 103 covers part of the side through holes 112 c.

The tuning strip 110 has a plurality of hollow areas 110a and non-hollow areas 110b alternately disposed thereon. The tuning strip 110 is of a ring shape, and the tweeter 103 can be adjustably shielded from the tweeter 103 by rotating the tuning strip 110. In other words, the tuning plate 110 rotatably covers the side through hole 112c to adjustably shield the tweeter chamber 103.

In the present embodiment, each of the hollow-out areas 110a is a sector area formed by arranging a plurality of small holes, but not limited thereto. For example, each hollowed-out area may be a non-fan-shaped area or an area corresponding to the shape of the side through hole of the frame.

In the present embodiment, the tuning strip 110 is a closed ring, but not limited thereto. For example, the tuning pad may be a non-closed loop.

In the present embodiment, the sound-field partition 104 has at least one sound-chamber through hole 104d on the side walls (104b, 104c) of the sound-chamber extension region 103b, and has an airflow adjusting element 104e covering the sound-chamber through hole 104d (for example, the airflow adjusting element 104e is adhered to the side wall to cover the sound-chamber through hole 104 d). Airflow regulator 104e is a porous vent assembly that evenly distributes airflow between the bass and treble chambers while maintaining uniform air pressure in the bass and treble chambers.

Referring to fig. 4 and 5, fig. 5 is a cross-sectional view taken along line 5-5 of fig. 4. In the present embodiment, the tuning strip 110 is rotatably embedded in the sliding slot 112d formed between the ribs 112a, but not limited thereto. For example, the tuning blade 110 is also rotatably disposed in the sliding slot 112e on either side of the frame 112 (e.g., rotatably disposed between the rib 112a of the frame 112 and the pitch domain partition 104).

The poke rod 110c of the tuning piece 110 protrudes out of the frame 112 for the user to apply force, and can poke the tuning piece 110 to rotate relative to the frame 112. In the embodiment, the poke rod 110c passes through the side through hole 112c of the frame, so that the poke rod 110c can be limited within the range of the side through hole 112c to be poked, thereby allowing the user to adjust the hollow area 110a to align to the high tone chamber or the low tone chamber more conveniently.

Referring to fig. 6 to 8, fig. 6 to 8 are schematic diagrams illustrating three application states of a speaker according to an embodiment of the invention. The high tone chamber 103 is defined as an area surrounded by the range wall 104 (see also fig. 3), and the low tone chamber 105 is defined as a space surrounded between the range wall 104 and a housing of the speaker (e.g., the housing 102 formed by the rear cover 102a and the earpiece cover 102b in fig. 1).

In fig. 6, the tuning strip 110 is adjusted by the moving rod 110c such that the hollow areas 110a are located at the side through holes corresponding to the low tone chambers 105, and therefore the side through holes corresponding to the high tone chambers 103 are shielded by the non-hollow areas 110 b. The bass range is now output more than the treble range.

In fig. 7, the tuning strip 110 is adjusted by rotating the dial rod 110c clockwise (compared to the position of the dial rod 110c in fig. 6), so that a larger part of the hollow 110a is located in the side through hole corresponding to the low tone chamber 105, and a smaller part of the hollow 110a is located in the side through hole corresponding to the high tone chamber 103, so that the side through hole corresponding to the high tone chamber 103 is shielded by the non-hollow 110 b. The bass range is still output at this time more than the treble range.

In fig. 8, the tuning bar 110 is further adjusted by rotating the moving rod 110c clockwise (compared to the position of the moving rod 110c in fig. 7), so that the hollow areas 110a are all located at the side through holes corresponding to the tweeter chambers 103 (the hollow areas 110a are shielded by the domain partition walls 104, so the drawing is not shown), and therefore the side through holes corresponding to the woofer chambers 105 are all shielded by the non-hollow areas 110 b. The output of the treble range is now greater than the bass range.

Referring to fig. 7 and 8, fig. 9 is a speaker (with a housing removed) with a tuning dial structure according to an embodiment of the present invention. Fig. 10 is a perspective view of a speaker having a tuning dial structure according to an embodiment of the present invention. The bottom end 120c of the tuning dial structure 120 is connected to the dial rod 110c (please refer to fig. 6) on the tuning piece 110, and the top end 120b thereof protrudes out of the sliding notch 102d of the outer rear cover 102a, so that the user can adjust the position of the tuning piece 110. The tuning toggle structure 120 further has a blocking piece 120a to shield the sliding gap 102d corresponding to the outer rear cover 102a, so as to prevent foreign matters or moisture from invading the speaker. It should be noted that the tuning dial structure is not limited to the above structure or design, and any structure that can be connected to the tuning blade and protrude outside the housing can be used, such as a knob that can be connected to the tuning blade and protrude outside the housing.

In summary, the speaker structure of the present invention is provided with the poke rod to facilitate the rotation of the tuning through the hollow areas and the non-hollow areas arranged in the tuning sheet in a staggered manner, and then the structure of the frame and the sound field partition wall is used for the user to freely adjust the amount of the high and low sound fields according to personal preference. The tuning poke rod is further in linkage structure with the earphone shell, and a user can adjust the distribution of high and low sound areas outside the earphone shell.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
