1. Technical Field
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
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.
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.
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.
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.
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.
Specifically, the sound box accommodating areas are hollow in structure and communicative with the wearable element.
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.
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.
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.
Specifically, the surfaces of the sound units from which the sound waves penetrate in the sound box accommodating areas face in different directions.
Specifically, the surfaces of the sound units from which the sound waves penetrate in the sound box accommodating areas face in the same direction.
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.
Specifically, the PCB may further include a battery.
Specifically, the wearable element hollow in structure increases the volume of the sound box accommodating areas.

For further understanding of the present disclosure, reference is made to the following detailed description illustrating the embodiments and examples of the present disclosure. The description is only for illustrating the present disclosure, not for limiting the scope of the claim.
The drawings included herein provide further understanding of the present disclosure. A brief introduction of the drawings is as follows:
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.
Please refer to
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.
The sound unit 221 of the present disclosure may be different from the conventional sound unit 1 shown in
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.
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.
As shown in
In one implementation, as shown in
Compared with the conventional arts, the present disclosure, may 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.
