BACKGROUND
1. Technical Field
[0001] The present disclosure relates to a wearable sound box apparatus; in particular,
to a wearable sound box apparatus with reduced-sized sound boxes (sound unit accommodating
areas) on both sides in order to achieve better low-frequency performance.
2. Description of Related Art
[0002] The conventional sound box apparatus typically is of larger size or occupies a larger
space compared with earphones, which gradually replace the sound box apparatus for
the playback of music. The conventional earphones generally rely on amplifiers inside
to output sound waves. Since the earphones are placed around the contour of the ears
and may be too close to eardrums, soft tissues of the ears may suffer from hearing
damages after going through lengthy usage periods. The above problem may be solved
if a portable sound box apparatus could be utilized.
[0003] However, integrating the conventional sound box apparatus into the portable sound
box apparatus in wearable form without sacrificing the characteristics of the sound
box apparatus could be challenging. For example, one wearable element has been employed
to be in connection with two sound boxes. With the sound box requiring some space
for the sound waves to reflect/bounce, such space and the surface from which the reflected/bounced
sound waves are outputted are often in the proximity (for instance, the space for
the sound waves to reflect is placed behind the surface from which the bounced sound
wave are outputted). Even so, when the space for the sound waves to bounce is too
small corresponding sounding performance may not be satisfactory. On the other hand,
if the space for the sound waves to bounce is too large carrying such sound box apparatus
may become burdensome.
[0004] One potential solution to the above problem as disclosed in the present disclosure
may take advantage of the space within the wearable element connecting the two sound
boxes.
SUMMARY
[0005] In order to overcome the aforementioned deficiencies, the present disclosure provides
a wearable sound box apparatus with a hollow connecting portion for increasing the
space inside the apparatus in addition to being equipped with a reflection tube. Accordingly,
the size of sound box accommodating areas at both sides of the apparatus may be reduced
to achieve the better low-frequency performance and render less burdensome the use
of the apparatus.
[0006] In one embodiment, the disclosed sound box apparatus may include a wearable element
having both ends thereof extended to form two sound box accommodating areas. The wearable
element may be structurally hollow, allowing for a printed circuit board (PCB), a
battery, and a reflection tube to be placed therein. A sound unit placed within each
of the sound box accommodating areas may be electrically connected to the PCB through
a signal line. When the sound unit operates, sound waves from the sound unit are reflected
within the wearable element and corresponding inverted sound waves are transmitted
out of the wearable element by the reflection tube.
[0007] Specifically, the sound box accommodating areas are hollow in structure and communicative
with the wearable element.
[0008] Specifically, the sound unit may further include a surface from which the sound waves
penetrate. The surface may include a cone, a dust cap, and a surround, a frame, a
damper, a voice coil, and a magnet set are integrated with the surface. The diameter
of a bottom of the frame is larger than the diameter of a top of the frame.
[0009] Specifically, the diameter of the damper is smaller than the diameter of the bottom
of the frame but larger than the diameter of the top of the frame.
[0010] Specifically, the diameter of the magnet set is smaller than the diameter of the
bottom of the frame but larger than the diameter of the top of the frame.
[0011] Specifically, the surfaces of the sound units from which the sound waves penetrate
in the sound box accommodating areas face in different directions.
[0012] Specifically, the surfaces of the sound units from which the sound waves penetrate
in the sound box accommodating areas face in the same direction.
[0013] Specifically, the reflection tube may further include a reflection hole on a surface
of the wearable element and a guiding pipe formed by the reflection hole extending
inwardly with respect to the wearable element.
[0014] Specifically, the PCB may further include a battery.
[0015] Specifically, the wearable element hollow in structure increases the volume of the
sound box accommodating areas.
[0016] In another embodiment, a wearable sound box apparatus may include a wearable element
having both ends thereof extended to form two sound box accommodating areas. The wearable
element may be structurally hollow, a printed circuit board (PCB) may be placed within
each or both of the sound box accommodating areas, a reflection tube may be placed
within the wearable element, and a sound unit may be placed within each of the sound
box accommodating areas and electrically connected to the PCB through a signal line.
When the sound unit operates, sound waves from the sound unit are reflected within
the wearable element and corresponding inverted sound waves are transmitted out of
the wearable element by the reflection tube.
[0017] Specifically, the sound box accommodating areas are hollow in structure and communicative
with the wearable element.
[0018] Specifically, the sound unit may further include a surface from which the sound waves
penetrate, the surface may include a cone, a dust cap, and a surround, a frame, a
damper, a voice coil, and a magnet set are integrated with the surface. The diameter
of a bottom of the frame is larger than the diameter of a top of the frame.
[0019] Specifically, the diameter of the damper is smaller than the diameter of the bottom
of the frame but larger than the diameter of the top of the frame.
[0020] Specifically, the diameter of the magnet set is smaller than the diameter of the
bottom of the frame but larger than the diameter of the top of the frame.
[0021] Specifically, the surfaces of the sound units from which the sound waves penetrate
in the sound box accommodating areas face in different directions.
[0022] Specifically, the surfaces of the sound units from which the sound waves penetrate
in the sound box accommodating areas face in the same direction.
[0023] Specifically, the reflection tube may further include a reflection hole on a surface

inwardly with respect to the wearable element.
[0024] Specifically, the PCB may further include a battery.
[0025] Specifically, the wearable element hollow in structure increases the volume of the
sound box accommodating areas.

DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
[0028] The aforementioned and other technical contents, features, and efficacies will be
shown in the following detail descriptions of a preferred embodiment corresponding
with the reference Figures.
[0029] Please refer to Figs. 2 and 3A-B of a partial schematic diagram of a wearable sound
box apparatus, an exploded view of a sound unit, and an integrated schematic diagram
of the sound unit according to one embodiment of the present disclosure, respectively.
As shown from the above figures, a wearable sound box apparatus 2 may include a wearable
element 21 having two sound box accommodating areas 22 extended from both ends thereof.
Each of the sound box accommodating areas 22, which may be structurally hollow, may
include a sound unit 221. The wearable element 21 may be structurally hollow as well,
allowing for a printed circuit board (PCB) 211, a battery 2111, and a reflection tube
213 to be disposed therein. The sound unit 221 within the sound box accommodating
area 22 may be electrically connected to the PCB 211 through a signal line 212.
[0030] The reflection tube 213 may define a reflection hole 2131 on a surface of the wearable
element 21 and a guide pipe 2132. The guide pipe 2132 may be formed by the reflection
hole 2131 extending inwardly with respect to the wearable element 21. When the sound
unit 221 operates, sound waves from the sound unit 221 may travel and bounce within
the wearable element 21. Reflected/bounced sound waves may become inverted counterparts,
which may be outputted by the reflection tube 213. The space for the sound waves to
bounce may be the space within the hollow wearable element 21, eliminating the need
of the large-sized sound box accommodating areas 22. Specifically, the sound box accommodating
area may only need to be large enough for the sound unit to be disposed. By further
adjusting the space within the wearable element 21, the space for the sound waves
to bounce may be sufficient for the better low-frequency performance to be achieved.
[0031] The sound unit 221 of the present disclosure may be different from the conventional
sound unit 1 shown in Fig. 1. As shown in Figs. 3A-B and 4, the sound unit 221 may
include a surface 2211 from which the sound waves may be outputted and such surface
2211 may include cone 2211, a dust cap 22112, and a surround 22113. The sound unit
221 may further include a frame 2212, a damper 2213, a voice coil 2214, a magnet set
2215, despite the conventional sound unit 1 may include a frame 11 integrated with
a cone 111, a dust cap 112, and a surround 113, a damper 12, a voice coil 13, and
a magnet set 14.
[0032] The frame 11 of the sound unit 1 is wider at its top (compared to its bottom), which
is not the case in the present disclosure. The frame 2212 may be with a frame top
22121 and a frame bottom 22122. The diameter of the frame bottom 22122 may be larger
than the diameter of the frame top 22121 with the diameters of the damper 2213 and
the magnet set 2215 smaller than the diameter of the frame bottom 22122 but larger
than the diameter of the frame top 22121.
[0033] Since the frame 2212 is wider at its bottom (compared to its top), which is oppositely
different from the structure of the frame 11 of the sound unit 1, the surface of the
damper 2213 and the size of the magnet set 2215 with a magnet and a pole piece may
enlarge. The increase in size of the damper 2213 and the magnet set 2215 may therefore
cause the magnetic circuitry to be larger than the vibration area of the cone 22111,
the dust cap 22112, and the surround 22113, reducing both Q value and the resonant
frequency of the sound unit 221 and increasing the compliance and the sound pressure
level (SPL) of the sound unit 221.
[0034] As shown in Fig. 5, because of the wearable element 21 the wearable sound box apparatus
may be placed anywhere of a human operator if allowed. For example, the wearable sound
box apparatus 2 may hang around the neck of the human operator 3. The surface from
which the sound waves may output could face in any direction to meet the needs. Specifically,
both surfaces 2211 from which the sound waves may be outputted of the two sound units
221 illustrated in Figs. 2 and 5 may face front at the same time, while the two surfaces
2211 from which the sound waves may be outputted may face right and left, respectively,
in the embodiment in Fig. 6. In short, there is no limitation/restriction to the direction
in which the surfaces 2211 from which the sound waves output of the sound units 221
face.
[0035] In one implementation, as shown in Fig. 6, the wearable element 21 may not be materially
flexible and the PCB 211 may still be placed within the wearable element 21. In another
implementation, the wearable element 21 may be flexible in nature and to avoid such
wearable element 21 from being overly bent to accidentally damage the PCB 211 the
PCB 211 may be alternatively placed within the sound box accommodating area 22.
[0036] Compared with the conventional arts, the present disclosure ,ay be with following
advantages: (1) with the wearable element being structurally hollow the space for
the sound waves to bounce before being outputted may increase to achieve the better
low-frequency performance and the volume of the sound box accommodating areas may
be reduced to render less burdensome the use of the disclosed sound box apparatus,
and (2) with the frame of the sound unit being wider at its bottom the surface of
the damper and the size of the magnet set may increase to enlarge the magnetic circuitry
to be larger than the vibration area, reducing the Q value of the sound unit and the
resonant frequency while increasing the compliance and the sound pressure level.

or having read this description, or having comprehended these examples, will occur
