Description

BACKGROUND

1. Technical Field

The disclosure relates to a toy, and particularly to a toy capable of emitting sound.

2. General Background

Toys that emit sound are very important in today's market. To make these toys competitive in today's market, people are continuously improving the sound quality of the toys. However, improving the sound quality of toys often means choosing more expensive sound components for the toys. As a result, the costs are often passed on to the consumers.

Thus, what is needed is a toy that can emit higher quality sound, but without more expensive sound components.

SUMMARY

A toy is disclosed. The toy includes a speaker, a control unit, and a printed circuit board carrying the control unit. The toy defines a first cavity and a second cavity substantially isolated from each other. The first cavity receives the printed circuit board. The second cavity receives the speaker.

Other advantages and novel features will become more apparent from the following detailed description of embodiments when taken in conjunction with the accompanying drawings. The isolation of the first cavity and the second cavity increases a dB sound pressure level.

DETAILED DESCRIPTION

Referring to FIG. 1, a human-figured toy 10 according to an exemplary embodiment of the present disclosure is disclosed. The human-like toy 10 includes a head 20, a torso 30 for supporting the head 20, two upper limbs 40 and two lower limbs 50 connected with the torso 30.

Referring to FIGS. 2 and 3, the head 20 includes a top part 21, a middle part 22, and a bottom part 25. The top part 21, the middle part 22 and the bottom part 25 form a first cavity 27 when the top part 21, the middle part 22 and the bottom part 25 are assembled together. The head 20 further includes a neck 26 for connecting with the torso 30. The neck 26 is attached, and extends out of the bottom part 25. The neck 26 defines a through hole 261 communicating with the first cavity 27.

The first cavity 27 receives a printed circuit board (PCB) 24 and a nose driving unit 23. The PCB 24 carries a control unit (not shown) for controlling the human-figured toy 10. The nose driving unit 23 includes an enclosure 230, a motor 231, and a nose 232. The motor 231 is mounted in the enclosure 230. A first end of the nose 232 cooperates with the motor 231. A second end of the nose 232, opposite to the first end, extends out from the bottom part 25. The motor 231 is controlled by the control unit and drives the nose 232 to extend or retract.

Referring to FIGS. 4 and 5, the torso 30 includes a chest 31, a frame 32, and a back 33. The frame 32 includes a first joint 321 for connecting with the neck 26, two second joints 322 for connecting with the two upper limbs 40, and two third joints 323 for connecting with the two lower limbs 50. The chest 31, the frame 32, and the back 33 form a second cavity 34 when the chest 31, the frame 32, and the back 33 are assembled together. The first cavity 27 and the second cavity 34 are respectively formed in the head 20 and in the torso 30, and only communicate with each other by a through hole 261 of the neck 26. Thus, the first cavity 27 and the second cavity 34 are substantially isolated from each other.

In the second cavity 34, an annular flange 310 is formed on an inner surface of the chest 31. A speaker 14 is attached to the flange 310. A baffle 324 formed on the frame 32 lies against the speaker 14 for preventing the speaker 14 from detaching from the flange 310. The control unit in the head 20 controls the speaker 14 to reproduce/output sound, such as vocal sound, via a wire (not shown) that is passed through the through hole 251 of the neck 26 to the first cavity 27. The chest 31 defines some holes 311 at the flange 310 for emitting voice from the speaker 14 outside the human-figured toy 10.

Referring back to FIG. 1, lower limbs 50 include battery cases (not shown) for receiving batteries. The human-figured toy 10 further includes sensors (not shown), for example, sound sensors or touch sensors, which are mounted at appropriate positions thereof. The control unit in the head 20 receives instructions from the sensors, and controls the nose driving unit 23 to extend or retract, or the speaker 14 to output sound correspondingly.

Referring to FIG. 6, a curve 1 is a tested frequency response curve when the speaker is received in the second cavity 34 and the PCB 24 is received in the first cavity 27, and a curve 2 is a tested frequency response curve when both the speaker and the PCB 24 are received in the second cavity 34. An average sound pressure level of the curve 1 is 68.33 dB SPL (dB sound pressure level). An average sound pressure level of the curve 2 is 65.74 dB SPL. Especially in the frequency range between 200 Hz and 2000 Hz, which is a common sound output range of the speaker 14, the sound pressure level of the curve 1 is always higher than the sound pressure level of the curve 2. Thus, when the speaker 14 and the PCB 24 are positioned in substantially isolated cavities, sound emitting from the toy 10 is of higher quality. Additionally, the sound components comprising the toy 10 may be purchased inexpensively thus reducing manufacturing costs of the toy.

Moreover, it is to be understood that the disclosure may be embodied in other forms without departing from the spirit thereof. Thus, the present examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the disclosure is not to be limited to the details given herein.
