Description

    FIELD OF THE APPLICATION
  • This application relates to the field of wireless devices, and more specifically, to a front resonator for a speaker of a wireless device.
    • BACKGROUND
  • Current wireless mobile communication devices include microprocessors, memory, soundcards, speakers, headphones, and run one or more software applications in addition to providing for voice communications.
  • One problem with current wireless devices pertains to speaker performance. Speakers in wireless devices require a front resonator to perform properly. The front resonator typically consists of a tube coupled to a front volume which is located in front of the speaker. Sound generated by the speaker travels through the front volume, through the tube, and into the air surrounding the wireless device where it is received by a user's ear. The tube and front volume are sized to obtain a desired frequency response. As such, to achieve a desired level of speaker performance, the size (e.g., length, volume, etc.) of the tube and/or front volume may have to be adjusted. However, an increase in the length of the tube, for example, will increase the thickness of the wireless device thus increasing the overall size of the wireless device, which is not desirable.
  • A need therefore exists for an improved front resonator for a speaker of a wireless device. Accordingly, a solution that addresses, at least in part, the above and other shortcomings is desired.

According to one embodiment, the speaker 134 is a dynamic speaker (e.g., a cone and magnet speaker). According to one embodiment, the front resonator 400 may be used in conjunction with a microphone or loud speaker. According to one embodiment, the edges of the enclosure 410 and plate 420 are rounded to reduce turbulence and to ease manufacturing tolerances. According to one embodiment, the enclosure 410 and plate 420 are made of metal and are welded or glued together. According to another embodiment, the enclosure 410 and plate 420 may be made of plastic. According to one embodiment, for a frequency response of approximately 4 kHz, each section 531, 541 of the tube 910 is approximately 0.4 mm high, by 1.2 mm wide, by 2.5 mm long and the front volume 900 is approximately 40 mm3. According to one embodiment, the front resonator 400 may include two or more tubes 910. According to one embodiment, the tube 910 may be formed or mounted on an outer surface 412 of the frame or enclosure 410.
  • Thus, according to one embodiment, there is provided a front resonator 400 for a speaker 134 of a wireless device 100, comprising: an enclosure 410 mounted over the speaker 134 and forming with an upper surface 1100 of the speaker 134 a front volume 900 for the front resonator 400; and, a horizontal (e.g., in the x - y plane) or approximately horizontal tube 910 formed or mounted on a surface (e.g., 411) of the enclosure 410, the tube 910 coupled (e.g., 500) to the front volume 900, and the tube 910 having at least one end 430, 440 to emit sound generated by the speaker 134 and passing through the front volume 900 and tube 910 from the wireless device 100.
  • The tube 910 may be horizontal (e.g., in the x - y plane) or approximately horizontal with respect to a vertical axis (e.g., the z - axis) of the front volume 900. The tube 910 may be formed or mounted on an inner surface 411 of the enclosure 410. The tube 910 may be formed by a plate 420 having an upper surface 421 mounted to the inner surface 411 of the enclosure 410, the upper surface 421 of the plate 420 having a trough 800 formed therein, the trough 800 and the inner surface 411 of the enclosure 410 forming the tube 910, the trough 800 having an opening 500 formed therein to couple the front volume 900 to the tube 910, the enclosure 410 having at least one opening 430, 440 formed therein and aligned proximate at least one respective end 530, 540 of the trough 800 to emit sound generated by the speaker 134 and passing through the front volume 900 and tube 910 from the wireless device 100. The trough 800 may be straight. The opening 500 in the trough 800 may be formed proximate a center of the trough 800. The opening 500 in the trough 800 may be formed in a bottom of the trough 800. The trough 800 may have a smooth shape with rounded ends. The at least one opening 430, 440 in the enclosure 410 may have semicircular and rectangular portions aligning with at least one respective end 530, 540 of the trough 800. The opening 500 in the trough 800 may have a rectangular shape. The upper surface 421 of the plate 420, the inner surface 411 of the enclosure 410, the trough 800, and a mounting plane of the speaker 134 may be parallel or approximately parallel. A volume of the front volume 900 and a volume of the tube 910 may be selected to provide a frequency response of approximately 4 kHz. The tube 910 may have first and second sections 531, 541. For a frequency response of approximately 4 kHz, each of the first and second sections 531, 541 may be approximately 0.4 mm high, by 1.2 mm wide, by 2.5 mm long and the front volume 900 may be approximately 40 mm3. The enclosure 410 may have a rounded, rectangular, open box-like shape. The inner surface 411 of the enclosure 410 may be an inner upper surface 411 of the enclosure 410. The plate 420 may be mounted in the enclosure 410 by welding or gluing. The enclosure 410 and the plate 420 may be formed from metal or plastic. The speaker 134 may be a cone and magnet speaker. The speaker 134 and front resonator 400 may be mounted within a case 150 of the wireless device 100. The tube 910 may be one or more tubes 910. And, the tube 910 may be formed or mounted on an outer surface 412 of the enclosure 410.
  • According to another embodiment, there is provided a wireless device 100 having a front resonator 400 as described above.
  • The above embodiments may contribute to an improved speaker system and may provide one or more advantages. First, the axis of the tube 910, 531, 541 is arranged horizontally with respect to the front volume 900 rather than vertically. As such, the overall height of the front resonator 400 is reduced and hence the overall thickness of the wireless device 100 may also be reduced. For example, if L = tube length and V = front volume, then Lnew / Lold = Vold / Vnew. As such, if Vnew = 0.5 Vold, then Lnew = 2 Lold. In other words, if the front volume is halved, tube length must be doubled which is not generally implementable in the vertical direction in a wireless device. Second, including the tube 910, 531, 541 within the front volume 900 rather than external to the front volume 900, according to one embodiment, allows for a further reduction in the overall thickness of the wireless device 100. Third, being contained within the enclosure 410, according to one embodiment, the tube 910, 531, 541 is physically protected from damage. Fourth, the use of two sections or tubes 531, 541 allows placing tolerances during manufacturing to be less strict (e.g., if one section or tube 531 is a bit longer, the other section or tube 541 will be a bit shorter). Fifth, selected rounding of the edges, corners, and surfaces of the enclosure 410 and plate 420 reduce turbulences and eases manufacturing tolerances. Sixth, the above embodiments may provide one or more of these advantages without significant adverse effect upon speaker performance.
  • The embodiments of the application described above are intended to be exemplary only. Those skilled in this art will understand that various modifications of detail may be made to these embodiments, all of which come within the scope of the application.
